One of the less common maintenance tasks that are performed on a car is changing the transmission fluid. Typically, you'll want to change the fluid every 80,000 miles or so along with the filter in the transmission. In the 1990's, there were more than a few major automobile manufacturers advertising that they had developed transmissions that required no fluid changes. The fluid inside was considered to be "lifetime" oil, meaning that it never needed to be changed. Over the years, it seems that this may have been an overly ambitious claim.

Originally, Mercedes specified that the 722.6 transmission was "sealed for life." This means that Mercedes has not specified a fluid/filter change interval. However, it appears that Mercedes has changed the "sealed for life" recommendation gradually by adding more frequent service in later model years.

There seems to be a couple different schools of thought when it comes to "lifetime" oil. Some people have said that you don't want to change the oil in the transmission because the increased viscosity of the new fluid can dislodge particles of dirt inside the transmission, clogging the new filter in a matter of miles. Other people will say that there are friction additives in the new fluid that are not compatible with the transmission.

In this article, we will go over the steps involved with draining out the old transmission fluid and adding new fluid. The first step is to jack the car up and secure it on jack stands. Please refer to our article on "jacking up your car" for more info. Next, slide underneath the car and locate the automatic transmission pan. This pan acts as a sump to hold the majority of the transmission fluid. You'll see a 5mm drain plug in the bottom of the pan. Now before you remove the old drain plug, you'll want to have a drain pan with a capacity of at least 11 quarts. It also helps to have plenty of paper towels on hand. This can be a messy job and it helps to have towels around to soak up the occasional spill.

NOTE: If you do not have the Mercedes special (dipstick) tool, you can still proceed with this DIY if you drain and very carefully measure the old fluid (write it down so you can't forget). The 722.6xx transmission fluid level is critical, three to four ounces plus or minus and it will not function correctly. Put back in the exact amount removed, this will allow you to change the fluid, and worst case; drive to a local independent MB shop to top off the fluid level.

You'll need to drain the fluid from both the transmission pan and the torque converter. On the bottom of the bell housing, you'll see a square window. On cars up to 1999, this window allows you access to the bottom of the torque converter. The safe way to rotate the engine for torque converter drain plug access is by turning the 27mm bolt on the harmonic balancer/crankshaft pulley. You will have to remove the front splash shield/sound panel in order to access the pulley nut from below. The shield is held in place with six 8mm bolts. Remove them and set the shield aside.

When rotating the crankshaft by hand with a ratchet and a 27mm socket, always turn the crankshaft in the same direction in which the engine runs. In this case, if you are standing in front of the car looking towards the back, you turn the engine in a clockwise direction. Also, do not forget to remove the ratchet before starting your engine!

Now move the drain pan under the transmission to catch all the fluid. Remove the 5mm drain plug in the bottom of the transmission. Fluid will come pouring out of the transmission. You'll probably also notice a strong burnt smell to the fluid. We certainly did with our project car. There's no official word from Mercedes-Benz about the burnt smell, but from the mechanics and sources we have spoken to, the smell indicates that the fluid is past its useful life and should not be re-used. Once drained, remove the 5mm drain plug from the torque converter and let it drain. Allow the transmission and torque converter to drain for at least 15 minutes. Make sure you also have a large container on the ground to collect all the fluid. It also helps to wear a set of protective gloves and have a roll of paper towels nearby to clean up any spills.

Once all the fluid has drained from the transmission and torque converter, remove the old sealing washers from the drain plugs and fit the new sealing washers from the filter kit on the drain plugs. Now re-fit the plugs in both the transmission pan and torque converter. Tighten the torque converter oil drain plug to 14 NM = 124 inch pounds. Torque the transmission oil drain plug to 20 NM = 177 inch pounds.

Locate the clamps on the outside perimeter of the transmission pan. These clamps are held in place by a 5mm Torx bolt. On the front right driver's side, one of the clamps is also held in place with an exhaust shield. Remove the clamps and you will be able to remove the transmission pan. Usually, it will just drop off the bottom of the transmission. In our case, it needed to be pried off. Once you remove the pan, you'll see both the valve body for the transmission as well as the filter. The old filter just pulls out of the valve body. Make sure you have the drain pan handy as you pull the filter out. Residual fluid will likely come streaming out of both the filter and the mounting hole on the valve body. It's a good idea to inspect the hole where it mounts and clean the mounting surfaces with a clean, lint-free rag. Take the new filter and place it in the mounting hole on the valve body. You'll notice a mounting tab on the top of the filter that fits on to one of the ribs of the valve body. Just push it up into place.

This is everything you'll need to change the fluid and filter in your Mercedes.
Figure 1

This is everything you'll need to change the fluid and filter in your Mercedes. Shown here are the filter kit for the transmission (This includes a new pan gasket, filter element, dipstick tube cap, drain plug seals, a quart of Mercedes automatic transmission fluid (approximately 10 quarts are needed overall) and the special dipstick tool you'll need to measure the level of fluid in the transmission.

You'll need to drain the old fluid from two locations on the transmission.
Figure 2

You'll need to drain the old fluid from two locations on the transmission. In this view, looking back towards the rear of the car, you'll see the main drain plug (purple arrow) near the rear of the transmission pan and the drain plug located in the torque converter (green arrow, plug not visible). In order to access the drain plug in the torque converter, you'll need to rotate the engine until the plug is accessible though the window in the transmission bell housing. In our case, the easiest way is to place a 27mm socket on the front crankshaft pulley and turn the motor over until the plug is visible in the window. You'll need to remove the front splash to access the front crankshaft bolt.

Remove the splash shield at the front of the engine by first removing the four 8mm bolts along the front edge (green arrows).
Figure 3

Remove the splash shield at the front of the engine by first removing the four 8mm bolts along the front edge (green arrows).

Next remove the six 8mm bolts on the front of each wheel well (green arrows) NOTE: Passenger side wheel well shown here, the driver's side is similar.
Figure 4

Next remove the six 8mm bolts on the front of each wheel well (green arrows) NOTE: Passenger side wheel well shown here, the driver's side is similar. Once all the bolts are removed, carefully lower and remove the front splash shield.

Now put a 27mm socket on the front crankshaft pulley (green arrow) and rotate the engine over by hand until you can see the torque converter drain plug through the window in the transmission as seen in <a href=# style=color:000080 id='In_text_6' onClick=PopUpMessage('In_text_6','images_small/Pic07.
Figure 5

Now put a 27mm socket on the front crankshaft pulley (green arrow) and rotate the engine over by hand until you can see the torque converter drain plug through the window in the transmission as seen in Figure 6 below.

You'll want to keep turning the engine until the drain plug is visible through the service window in the transmission as seen here (green arrow).
Figure 6

You'll want to keep turning the engine until the drain plug is visible through the service window in the transmission as seen here (green arrow).

Remove the 5mm drain plug in the torque converter and allow it to drain into a large container.
Figure 7

Remove the 5mm drain plug in the torque converter and allow it to drain into a large container.

Next, loosen and remove the mm drain plug at the rear of the transmission.
Figure 8

Next, loosen and remove the mm drain plug at the rear of the transmission. Be ready for the old fluid to come spilling out of the transmission.

Allow the transmission to drain for at least 15 minutes.
Figure 9

Allow the transmission to drain for at least 15 minutes. Make sure you also have a large container on the ground to collect all the fluid. It also helps to wear a set of protective gloves and have a roll of paper towels nearby to clean up any spills.

Once drained, locate the clamps that hold the transmission pan to the bottom of the transmission (green arrows).
Figure 10

Once drained, locate the clamps that hold the transmission pan to the bottom of the transmission (green arrows). These clamps have a 5mm Torx bolt that holds them in place. Remove the bolts and the clamps will just slide off. Keep in mind that the front clamp on the passenger side will be attached to a heat shield.

Now carefully pry the pan off the bottom of the transmission.
Figure 11

Now carefully pry the pan off the bottom of the transmission. You'll probably have some fluid spill out as you do this, so it's a good idea to have a large drip pan underneath. In our case, the smell from the old fluid was enough to tell us that the fluid was well past it's service life. You'll notice an acrid, burnt smell. Once the pan is removed, you'll see the filter (green arrow) and valve body (purple arrow) directly above it.

Remove the old filter by simply pulling it out of the valve body.
Figure 12

Remove the old filter by simply pulling it out of the valve body. It's also a good idea to inspect the hole where it mounts and clean the mounting surfaces with a clean, lint-free rag.

The wiring harness connector for the transmission is known for having problems with leaking.
Figure 13

The wiring harness connector for the transmission is known for having problems with leaking. It is located on the right side of the transmission just above the fluid pan. Shown here is the locking tab that holds the connector in place (green arrow). Rotate the tab counter clockwise to unlock the harness connector.

Once the locking tab is released, pull the harness connector out of the transmission.
Figure 14

Once the locking tab is released, pull the harness connector out of the transmission. Inside, you'll see a small 7mm bolt, holding the harness connector to the transmission (green arrow). Loosen this bolt and pull the harness connector out of the transmission.

Shown here are the two O-rings that must also be removed from the inside of the housing (green arrows).
Figure 15

Shown here are the two O-rings that must also be removed from the inside of the housing (green arrows). Usually, they stick inside the transmission, although they can also still be attached to the connector.

Here is the new harness connector with the updated O-rings (green arrows).
Figure 16

Here is the new harness connector with the updated O-rings (green arrows). Install the new harness connector in the transmission housing and lightly tighten the bolt holding it in place.

Shown here is the new connector in place with the locking tab rotated up.
Figure 17

Shown here is the new connector in place with the locking tab rotated up.

Take the new filter and place it in the mounting hole on the valve body.
Figure 18

Take the new filter and place it in the mounting hole on the valve body. You'll also notice a mounting tab on the top of the filter that fits on to one of the ribs of the valve body. Just push it up into place.

Now take the transmission pan and pull the old mounting gasket off the top of the pan.
Figure 19

Now take the transmission pan and pull the old mounting gasket off the top of the pan. It should just peel off the top lip of the pan.

The next step is to clean out the bottom of the pan.
Figure 20

The next step is to clean out the bottom of the pan. Keep in mind that all of the residues and accumulated junk that gets into the fluid will eventually deposit itself here. You might be surprised at what is sitting at the bottom of the pan.

Now take the new gasket from the filter kit and press it on to the top lip of the transmission pan.
Figure 21

Now take the new gasket from the filter kit and press it on to the top lip of the transmission pan. Once the new gasket is seated on the pan, place it back up on the transmission and re-attach the bolts and clamps. Tighten them down snugly, but not so much you strip them out.

Now, from the top, locate the automatic transmission filler hole near the firewall on the passenger side of the engine.
Figure 22

Now, from the top, locate the automatic transmission filler hole near the firewall on the passenger side of the engine. You'll notice a plug in the top of the tube that reads "MB Workshop Only". You'll need to remove this plug to continue. You can just barely move the red release lever inside the plug with a small screwdriver as shown here. Once the release is free, just pull the plug up and out of the tube.

Now fill the transmission with 5 quarts of Mercedes-Benz branded transmission fluid (part no.
Figure 23

Now fill the transmission with 5 quarts of Mercedes-Benz branded transmission fluid (part no. 001-989-21-03-10) it is critical that you use the original MBZ fluid in this application. You'll next need to jack the car up on four jackstands and make sure it is secured safely. You need to run the car through all the gears to circulate the fluid through the transmission. Having a small amount of fluid in the transmission helps to prime the system.

Now look at the dipstick tool for the transmission.
Figure 24

Now look at the dipstick tool for the transmission. You'll see two gradients on it. One level shows the transmission level at 25 degrees C, and the other at 80 degrees C. The idea here is that you want to check the level of the fluid at two different temperatures. As the temperature of the fluid increases, the level of the fluid will rise. The 25 degree mark (green arrow) is supposed to indicate a cold fluid level while the 80 degree mark (purple arrow) is with the transmission fully warmed up.

Now start the car with the wheels off the ground and run it at idle through reverse, drive and all other gears for 30 seconds each.
Figure 25

Now start the car with the wheels off the ground and run it at idle through reverse, drive and all other gears for 30 seconds each. The idea here is to circulate the fluid already in the transmission. With the engine still running, place the dipstick tool into the tube and push it in as far as it will go. Keep in mind that it will not go all the way down to the handle.

Here's where the procedure gets a little tricky.
Figure 26

Here's where the procedure gets a little tricky. You'll need to monitor the temperature of the fluid as the car warms up. For this task, an infrared pyrometer is an invaluable tool. This tool allows you to point a laser beam at any given object and see the temperature in both Fahrenheit and Celsius scales. In this case, you would want to set the tool to Celsius and point it at the transmission pan until it reads roughly 80 degrees C (this will take a while). At this point, pull the dipstick out and read the level. If the level is correct, it will read between the lines for the 80 degree gradient on the dipstick. If it does not register, add more fluid until it does. You'll need to have the engine running and the transmission in park as you do this. Keep in mind that you will need to circulate the fluid between each time you fill by running the transmission through the gears. Once done, put the car back in park and re-check the level. It's a time consuming process, and you want to make sure that you get it just right. The fluid level MUST be correct or you could cause damage to the transmission.

Here's a shot of what the dipstick tool should look like at the correct fluid level at 80 degrees Celsius.
Figure 27

Here's a shot of what the dipstick tool should look like at the correct fluid level at 80 degrees Celsius. As you can see here, the fluid level comes up and over both sets of marks on the tool, indicating that the fluid level is correct. You want to aim for in-between the marks on the upper, 80 degree gradient. In this picture, we are just a tad on the high side. Once you have the fluid level correct, lower the car down off the jackstands.

Dilip Comments: I have MB E200 1986 model the ideling was very high could not even set it with the dingostic mb star so changed the throttle control actuator the rev is under control at 8.5 but asa I put in D mode the car wants run away and have to control using brakes until on a straight run at stop again have to control the drag its not normal smooth run after the stop how can I adjust the modulating pressure in the G/Box? How to solve this problem of dragging even when the rev is at 8.5/9 especially when reversing
November 20, 2016
  Followup from the Pelican Staff: Sounds more like a major vacuum leak than a trans pressure problem. - Nick at Pelican Parts  
GRC911 Comments: Great article and very helpful, thank you for creating this for all to use. A couple things I noticed while changing the fluid for the first time on my '99 with ~195K miles. The fluid that I was able to drain when I dropped the pan only totaled ~3L. The bolt to the torque converter was frozen and I stopped trying to prevent it from snapping.
I refilled the transmission with the same amount that I took out. After shifting it through the gears I took my first reading and nothing came up on the dipstick. Long story short, I've added almost 4L and it is just now to the lower gradient of the 80 degree mark. It's now shifting smoothly, no cold weather problems, and there no leaks!

Carnut Comments: How does the transmission fluid go into a 2007 Mercedes CLK550 Cabaret? Is there a place under the engine cover to pour it in remove the top cover or do you have to buy a pump and pump it back up into the transmission through the dipstick hole from underneath the transmission. I can't find a single picture that shows this and I have heard that the transmission has to be pumped in instead of poured in. Any information would be appreciated so I can buy the right parts.
August 6, 2016
  Followup from the Pelican Staff: There should be a tube with a cap in the engine compartment. You will need to buy a dipstick for your model, then use the dipstick to check the level and top up via the tube if needed. The fluid should be between the two marks of the dipstick when the transmission is cold with the engine idling.

kingzain Comments: Just bought a 2007 R320 CDI. its a diesel engine and engine sound is really good.
But as I was about to leave dealership, This car has no power - period. It runs, but on hills or even flat road even with the gas pedal on the floor - it just does not accelerate well at all, check engine light came on, is it a big problem to be worried about because I just bought it, and i decided to take it back to the dealership for them to fix it.They said it will be fixed tomorrow. Any thoughts would be appreciated.
July 8, 2016
  Followup from the Pelican Staff: Hard to say without knowing the code stored. COuld be a fuel delivery issue, engine misfire or restricted exhaust. - Nick at Pelican Parts  
Carnut Comments: Thanks for the note about the 550CLK - not a single fault code appeared and since the rain storm stopped and the car was parked for that short period the transmission has been working perfectly. I expect it was the electronics that got wet. Had lots of Mercedes and this is the first for this problem. Of course I have never seen so much rain like driving through a small lake with all the water on the road.

Carnut Comments: I have a CLK550 that went into Limp mode in a large rain storm. I parked it for one hour and it works fine now. Is it something that I need to look at or is this something that happens in huge rain storms - lost of water on the road that splashed up under the car over 30 miles of driving.
June 30, 2016
  Followup from the Pelican Staff: COuld be water intrusion into the wiring harness. Try drying it out and seeing if the fault codes can be cleared. - Nick at Pelican Parts

jeffdee Comments: hi I have a Mercedes c32 amg 02reg its jerking in gears wen cold wen warm its not bad I have not had the fluid change can you help
June 16, 2016
  Followup from the Pelican Staff: This could be a slip caused by low fluid or low pressure. Start by checking your fluid level. If it is OK, you may have worn parts causing a pressure drop and slip. I would have it checked before it gets much worse.
- Nick at Pelican Parts
 
RickMia Comments: I have a 2006 Mercedes Benz SLK 350, and have never checked the transmission. Been having trouble with trouble with auto shifting gears, and I was told to add transmission fluid. Is this possible with this car, as I am not able to find anything online where to add fluid? I bought dip-stick and fluid but not sure where to pour or measure. Thanks
June 15, 2016
  Followup from the Pelican Staff: It is possible to add fluid to your vehicle. You will have to add through the dipstick tube. - Nick at Pelican Parts  
Ngethe Comments: My 1998 E280 Mercedez has hard start very often. Once in a while it starts same time but most of the time...it hard start, I'm even worried that my started will not last long. Please Help
May 27, 2016
  Followup from the Pelican Staff: I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume, quality and engine compression. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

TRAVOLTA Comments: Hello
Any idea if the AMG C32 2002 year has the drain plug on the torque converter ?
otherwise I will need to do a flush by removing the trans cooler line. Which cooler line is the return to the transmission ? Upper or lower banjo bolt ?
I have a leak where the upper cooler pipe joins the radiator. Must be the o-ring.
would l need to lube the new o-ring or install it dry on the cooler line.
cheers and best regards
May 27, 2016
  Followup from the Pelican Staff: There is no torque converter drain.

Benz instructs to remove the lines at the trans, then remove fluid from cooler. Reinstall lines and fill.

Always lubricate O-rings with clean fluid. - Nick at Pelican Parts

March 10, 2016
  Followup from the Pelican Staff: I don’t have that info.


I would grab a repair manual. It will have the procedure, special tools and torque specs.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts
 
Frank Comments: For completeness, at what point do you replace the torque converter drain plug and the transmission drain plug? What torque?
I'm guessing before Figure 23.

At first I thought that you didn't have them plugged to flush out any old residue that's on the walls of the transmission and converter as you pour in some new oil.
March 9, 2016
  Followup from the Pelican Staff: The seals for the plugs should be replaced each time the plug is removed. The plugs are reinstalled as soon as the fluid has completed draining.

Jaccues Comments: Hi Nick, i followed the instructions to remove the connector adapter plug on my c200 elegance / 722.6 after it went into limp mode at the time i just thought it was low fluid and put in one liter as the plug came out a lot of oil came out as well, about two liters, is that much oil meant to come out from there if over filled?
February 12, 2016
  Followup from the Pelican Staff: it would depend on how much it was over-filled by. I can't assume the amount. Your best bet is to check the fluid level and drain or top up as needed. - Nick at Pelican Parts

Anthony Comments: Hello. The ATF process with pictures is good. I have an ML350 2007. I believe the oil has to be pumped into the pan via a adaptive tool. Will I have to reset the computer. Can it be done with OBDII tool if I trip the computer? Also, is it a good time to change the conductor plate and the plug housing since this is a known problem with shifting.
November 29, 2015
  Followup from the Pelican Staff: OBD II tools usually can't perform factory specific functions. You will need a mercedes-benz scan tool.

Changing the additional items it wise while in there. - Nick at Pelican Parts

Tom Comments: I have a 1982 380SL. When the transmission shits from 2d to 3rd it slips and engine revs. However if I accelerate and not just ease off a stop it shifts normally thru the gears.
October 20, 2015
  Followup from the Pelican Staff: This could be a slip caused by low fluid or low pressure. Start by checking your fluid level. If it is OK, you may have worn parts causing a pressure drop and slip. I would have it checked before it gets much worse.

The Captain Comments: Hi. I recently changed the transmison oil and fliter for mercedes s500 model 1994. Now i find that the transmision changes up gear @20 km speed and into second gear @40 km. then speed builds up slowly till the desired speed without an issue.
Then when i kickdown the accelerator paddel, normally it changes dowgear to speedup more and then changes gear. Now this doesnt happan now.
So, why the gear changes into second and third gear so soon, and the kickdown doesnt work?

Moondogg Comments: Great article on changing tranny fluid - all directions clear and concise. However, my 1999 E320 222,000 miles required a 17mm hex bit to turn crankshaft - not a 27 mm socket as you show. After draining torque converter and transmission pan I moved on and removed valve body and replaced conductor plate, and plug housing. Plug housing was half full of tranny fluid when I pulled the plug, so cleaned out plug using contact cleaner. Put it all back together and filled using 10 liters of Shell ATF 134. How to suck out 1.5 oz to get to proper level when hot 80 C. Car shifts better than I remember. Thanks for online tutorial!

sheils Comments: Hello forum friends. I have a 1995 mercedes e320 4d sedan chassis 124 engine 104.992 german manufactured. Recent issues with going in reverse while going forward is perfect led to a trans flush and new oil filter. Are there diagnostic codes in ECM for this year vehicle? Any other potential issues external or attachments to the trans to consider. How would the transmission overload protection switch problem be detected or a problem with the waterpump, clamps, drain plug torque or colling lines play a role.

Mike Comments: Hi,
Very interesting article - thanks.
Couple of questions:-
You say "On cars up to 1999, this window allows you access to the bottom of the torque converter". What about later models? I have heard that there is no plug in the later converters my car is a 2001.
Also, when draining the fluid, I assume that some old fluid remains in the cooler and connecting pipes. Does this matter?
Thanks again.
November 26, 2014
  Followup from the Pelican Staff: Newer models may not have a torque converter drain, this is correct.

When performing a drain and fill, only some of the fluid comes out. In order to replace it all, you would have to use a flush machine, that replaces the fluid as it drains it, via a cooler line. - Nick at Pelican Parts

Willing to give ay detail - filter and gasket also changed. Was a little milky at first - radiator oil coolant was fixed, and now ATF colour gone back to reddish colour.

I understand from your photo no. 26 above showing the cap and small screwdriver being used after the red locking tab has been broken off,, but am unclear as to precisely what to do to unlock the cap with the screwdriver to ensure it doesn't allow the tab remnant to drop down the filler pipe Appreciate your help.

  Followup from the Pelican Staff: The article states Now, from the top, locate the automatic transmission filler hole near the firewall on the passenger side of the engine. You'll notice a plug in the top of the tube that reads ”MB Workshop Only". You'll need to remove this plug to continue. You can just barely move the red release lever inside the plug with a small screwdriver as shown here. Once the release is free, just pull the plug up and out of the tube.

You only lever the tab as you pull the plug off dipstick tube. - Nick at Pelican Parts

Followed procedure for removing cap, first pulling red tab off and then trying to release the cap by using small screwdriver to depress tab remaining inside cap. However, the remaining portion of the red tap has dropped down the filler tube and presumably now mixed in with transmission oil in the sump. Will this cause any problems with transmission if I leave it or do I have to resort to draining transmission oil ? Thanks, Nick

MERCEDESTIFFANY Comments: I have a 2000 E320 4matic Wagon with 276,000 miles on it, recently went into soft limp mode changed conductor plate and ran fine for a few weeks then slipped into hard limp, factory reset and it seemed fine for about a week but now I'm hearing that hissing/whining when changing gears, so my question is 1. is my trans finally just going 2. if it is can I just change the trans pump if so where located and how 3. or could it just need a proper trans oil change and top off like you show in this article?

PIP Comments: Hi Phil Here I have a CDi 2200 with 81,000 on the clock, and my maintenance records do not show any changing of the auto gearbox fluid. The gearbox has recently started to make a light ticking noise, not unlike a small fan rotor just catching. We reckon a fluid change could eradicate this as the car otherwise runs very well. Cpuld you please comment. Thanks

Nazibwoi Comments: Thanx a lot nick! U guys rock! I'm all the way in Nigeria and we don't have access to MB approved services, so before anything is done I like to double check. Talked with my repair man and he said it probably the fuel pump cos I normally run my car till the tank has about 5 liters left. Anyways I filled the tank and the problem stopped. So do I need to still change the pump cos my car starts on first turn of the ignition so I'm thinking the pump is not so bad..... Really appreciate though........u r the best!!!!!!!

GrooveMechanic Comments: Hi I have a question. I have a 2001 CLK320 transmission 722.6 I believe

For the past month or so It's been doing 2 things infrequently:

B sometimes after driving a bit and coming to a stop will be stuck in second gear when I take off again. Coming to a stop, shifting to Park then shifting back to drive fixes it

B more rare after driving and coming to a stop or while driving after taking my foot off the gas will shift to neutral.
coming to a stop, putting car in Park, turning off ignition and starting up again fixes it.

The occurrences of these things happening drop to almost 0 once the car has been running for 5-10 min or so.

Garyjac Comments: Hello, I have an 03 Sprinter with only 41,000 miles, stuck in 2nd gear limp mode?

TCU shows no codes, I've changed wiring harness connector, 2 times [first time it started to leak again after about 10,000 miles], I checked it and it is dry as a bone. I've done 2 fluid and filter changes with no problems. I was using the truck to it's max weight so I wanted to be sure I was taking good care of it.

I have two 1998 ML320s as our daily drivers, and I have had to remove and repair both of those transmissions so I didn't want this one going bad.

Anyway, the Sprinter never had any trouble, until I stopped to let wife out at the mall, and when I went to pull away, no shifts, on other gears! I can backup and go forward but cannot get any other forward gears. The shifter will not read anything but D/N/R.
It was a long/slow 10 miles home. I've being reading and testing for around two months on and off, but have not fond the trouble. Any ideas would be great, Thanks, Gary

  Followup from the Pelican Staff:
You could have a mechanical failure inside the transmission or a shift module issue.

If it is in LIMP MODE, there will be fault codes stored. I would start by checking the vehicle for fault codes. If multiple systems are not working properly, fault codes will be set. This will be your best bet when diagnosing.

Also looking the previews steps in photo #7 draining the torque converter and the reservoir is +/- 9 liters, if I only put 5 quarts like in your photo #23 and turn the car on; doesn't mean I will damage the transmission for low level transmission fluid? Or should I keep adding transmission fluid until I reach all transmission fluid I remove previously?

Tom Comments: Please help. I have a 1995 E320 wagon. A hole in the oil pan required raising the motor about 6 inches to R&R. After fixing that, I noticed the shifter is a little off, i.e., for reverse, the gear shift is between P and R. Started car and drove a half mile then suddenly in a 30 second time span all forward and reverse gears are gone. I took off the trans pan and found the filter was very bad - the filter material had been sucked about 3-4mm up into the tube that goes into the valve body, but the filter material all seems to be there. Reassembled with new filter. Still no gears. ATF level is correct.

keaton Comments: I have a 98 ML320, suddenly the car doesnt move, it s going in gear but won't move or move very slightly. I will try to unplug the electrical connector at the transmission and see if the vehicle will move forward in third to see for a bad transmission. should I disconnect battery when doing it or should I disconnect when engine is on?
Thaks for help

Macky Comments: 97 S320 with 722.6 5-speed trans, wont shift of out of 1st gear when cold, from startup until 60-90 C.. When warmed up tranny is ok.

What seems to be the problem wit this car/tranny?

  Followup from the Pelican Staff: This could be ab ad electrical connection of faulty module. I would start by checking the vehicle for fault codes. - Nick at Pelican Parts  
Ken Comments: Nick, thanks for answering my transmission dipstick question. What made it hard was that the dipstick clamp had a groove at the end that mated exactly with the top of the dipstick tube, making it look like for some reason it was supposed to. Not so. Thanks so much. Ken

MacJ Comments: Hi there. I have a ML320 which has an issue changing gears from cold, If you manually shift from 1st thru the gears it will select them fine. Once it is warm there is usually no problems in D from then on. If you stop for a period of time you need to repeat the process. I have changed the fluid and filter. I have noticed it go into "limp mode" twice but stop and start cures this. There is also a rattle from the N/S cat so its about to fail. Any clues guys
December 29, 2013
  Followup from the Pelican Staff: I would start by checking the vehicle for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing. As if it is in limp mode, there will be fault codes stored.

18thangel_ Comments: Ok, I finished up my transmission flush, but I can't get an accurate reading. I have two different infrared thermometers and the hottest I can get the surface of the drain pan is 51 degrees celsius. This is after 30 minutes in downtown driving or a 400 mile highway drive. Nothing, I can't get it to the 80 C mark. Any suggestions? I'm driving a 97 E300.

Thanks!
December 28, 2013
  Followup from the Pelican Staff: If unsure, warm engine until it reaches operating temp, then recheck. A scan tool really is the best method for checking fluid temp. - Nick at Pelican Parts

Ken Comments: Re Kerry's request for clarification on my Aug 17, 2013 post on 1995 E-320 oil check. I was referring to transmission fluid. Dipstick locks in place with a clamp hinged to the cap to swing down and grip the dipstick tube. Question was whether dipstick clamp should be up or down when checking the level. Makes an inch or so of difference on how far the dipstick goes in. I assume clamp should be up and out of the way, but need to make sure the oil dipstick has no such complications. Thanks, Ken
December 15, 2013
  Followup from the Pelican Staff: The cap should be folded out of the way. - Nick at Pelican Parts  
rhys Comments: I have aclk w209 220cdi and have been experiencing some hard shifting for the first mile when very cold eg first thing in the morning.

December 14, 2013
  Followup from the Pelican Staff: There may be a pressure problem. If the trans ecu see slip and raises the pressure, you may feel hard shifts. Have you check the vehicle for fault codes? - Nick at Pelican Parts  
Pitta Comments: Any tips on checking level/changing transmission fluid on a Mercedes V230 automatic 1997.

December 11, 2013
  Followup from the Pelican Staff: Check fluid level using dipstick with engine idling and vehicle parked on level surface. Fluid should be between min and max at 176°.

To service, drain fluid from drain plug, measure amount that came out. Fill with same amount through dipstick tube. Then check level and top up if needed.- Nick at Pelican Parts
 
1995 E 320 Comments: Previous comment correcton - the E320 has replaced 1998 transmission - not 1990.

1995 E320 Comments: Have 1995 E320 with 1990 replaced transmission. driven daily and runs well but sometimes 5% of time when put in D or 3 from stop it only revs as if in Neutral...have to put into 2nd low and get to 10mph before shifting manually into D or 3. - ...but fine during driving and above 10mph. could it be trans fluid leak? , should I try trans fluid Flush or is there another possible issue?
December 4, 2013
  Followup from the Pelican Staff: Sounds like the transmission is old and worn out. Changing the fluid MIGHT help--but only if fluid changes have been regular in the past. If the fluid is very old and has not been changed in a long time, changing the fluid now might stir up old deposits in the sump and make things worse instantly. - Nick at Pelican Parts  
should have bought a ford Comments: my 1999 Mercedes benz c230 compressor will not shift from first gear while driving, could this be an electrical issue?
November 28, 2013
  Followup from the Pelican Staff: This could be a few things. Your best bet is to scan the car for fault codes using a Mercedes-Benz scan tool.

With that said, if you recently spilled a drink on your center console, the shifter module could be faulty. It is located under the shifter, in center console.

Next could be the conductor plate which is located in the transmission, on the right inside. - Nick at Pelican Parts
 
Max Comments: Big thanks for your answer.
So what should be then the solution regarding the catalytic converter and the drop of transmission power.
November 25, 2013
  Followup from the Pelican Staff: Replace the catalytic converter with a new one and repair the problem causing the fault in the transmission. I would scan the trans control module and check for fault codes. The fault code will lead you to the area of the problem. - Nick at Pelican Parts  
Max Comments: I have an E240 automatik 2006 120000k. first problem is that the transmission power have droped; did the last transmission service in 90000km. secondy i remove the catlytik on the exaust and i aways have the engine ight on dashboard time to time.
Thanks for your advices
November 23, 2013
  Followup from the Pelican Staff: If you remove the catalytic converter the O2 sensors are going to read the same and the ECM will flag a code for a bad catalytic converter. Also, if the transmission is stuck in 3rd gear that means it is in fail-safe and has set a trouble code. - Kerry at Pelican Parts  
Lecha Comments: Hi, would you please explain why in the final step of the transmission fluid change process you need the special dipstick tool to check the fluid level and why can't you use the standard dipstick that it is used when checking transmision fluid level on any given day?
November 17, 2013
  Followup from the Pelican Staff: The vehicle does not a dipstick from the factory. It just has a cap. the "tool" is the dipstick. - Nick at Pelican Parts  
Vchurch Comments: Ok, so I've been doing the transmission fluid change for the past few days and have been using the following directions. Everything was going great until the final step. I went to put the torque converter drain plug back on and now it wont tighten or loosen from the torque converter. There's no space for me to squeeze in a flat head to back it out. I've tried a magnet to create downward force, flat head and other things in between. Any ideas? I'm nervous about drilling it.
November 12, 2013
  Followup from the Pelican Staff: So I'm guessing the threads are stripped. Can you grab it with a vise grip? If you can drill it you can drill a much smaller hole and then thread in a screw adn try to pull on it while spinning it loose. Just an idea. - Kerry at Pelican Parts  
sakadezulu Comments: My 1997 E 420 has 73000 miles but the transmission, but my transmission fluid look like is has some water in it, having stayed one place for a long time. Another problem is that the alarm goes of each time I want to start the key. This started when I noticed that the battery was very weak, I bought anew battery and problem still continues. What can I do to rectify both proble
November 8, 2013
  Followup from the Pelican Staff: You should flush out all the transmission fluid and replace it with fresh fluid. As far as the siren, is the car starting or is the alarm preventing it from starting? If it's starting then the alarm module is not not seeing that you are getting into the car. Try using the key in the door to unlock the car. On American models this shuts off the alarm and the siren should not go off. - Kerry at Pelican Parts  
leerenn Comments: Follow up, my 01 mb e320 has 198000 miles no problems, 2nd owner, what are chances of tranny lasting to 250,000? what would you do to increase likelihood of keeping car running good to 250,000? I know a lot of MB's go 250,000 easily, but some seem to have problems?
Great web site, thanks so much
November 8, 2013
  Followup from the Pelican Staff: Accelerate slowly if you can and avoid traffic. Flushing the fluid at this mileage is dicey! Good luck.. - Kerry at Pelican Parts  
chevvy Comments: can you tell me why my 99 ml430 transmission whines worse than my wife? if I turn the air up to full it is not so noticeable but on quiet days , its a bitch,...... the trans stilll works fine, its just the noise.
November 5, 2013
  Followup from the Pelican Staff: Without being there it is hard to say since I cannot hear the whining (divorced so that's how if fixed you second problem). All you can really do is check the fluid level and possibly change the fluid. You might have a clogged trnamission fluid filter restricting oil flow but that is only a guess. However it could be damage inside the transmission. - Kerry at Pelican Parts

November 5, 2013
  Followup from the Pelican Staff: How much did you add and did you put it in the transmission and not down the engine dipstick? (Don;t be offended I've seen professions make that mistake). You may want to drain borh your transmission fluid and engine oil and refill them. - Kerry at Pelican Parts  
Kevin O Comments: I have a 2000 320 4matic wagon with 110k miles. At highway speed 75 mph, check engine light comes on and car runs rough. When I stop car, and restart, engine runs fine again. Transmission shifts abruptly when starting up again. This may happen just once on a long highway trip. Otherwise, engine and trans perform well. Suggestions?
November 3, 2013
  Followup from the Pelican Staff: If you can have someone pull the DTC (codes). This could be anything from a bad coil, injectors or a vad fuel pump but I cn;t rule out a MAF. Anyone would need to trouble codes that turned on the check engine light - Kerry at Pelican Parts  
Janders Comments: Hi, I have an issue with my e430 whereby which the transmission surges a bit when slowing down and coasting. The feeling is almost like when a manual transmission is in too high of a gear. Any suggestions if a fluid change may help. When shifting the car into neutral, I have not noticed this surge.
November 3, 2013
  Followup from the Pelican Staff: Sounds like your sprague clutch is not letting the engine free-wheel under deceleration. Try flushing out the transmission fluid and a new filter and see if that does not help. - Kerry at Pelican Parts  
leerenn Comments: MB 01 E320 - 198000 miles, runs great, would it be reasonable at every oil change 6000 - 7500 miles is my plan to simply drain trans oil from drain plug, and refill. Over the course of time this would ultimately keep the trans fluid relatively new/good condition. I did this with my 96 honda accord 200,000 miles and it seemed to run like new until my daughter crashed at 250000 not her fault.
November 2, 2013
  Followup from the Pelican Staff: Your changing the transmission fluid way too much. Mercedes Benz now recommends 40,000 miles for new transmissions, 7500 miles is nothing for transmission fluid since it is only used as a hydraulic fluid for power transfer. 25,000 miles would be considered short but safe. If you are doing this to a transmission with 198,000 miles already on it the damage has been done and new fluid will not help very much. Sorry - Kerry at Pelican Parts  
Khim Comments: Hi, I've a W210 E200 YR 1998 CC from UK. . If you speed and then slow down for some reason, when you try to increase speed, it refuses. The rave will be high but no power. Could my transmission be ceasing? Thanks.
October 27, 2013
  Followup from the Pelican Staff: Yes it sounds like a transmission problem. Try chenging the fluid and checking the fluid level and see if this does not fix the problem. - Kerry at Pelican Parts  
Haggisnneeps Comments: Hi, I have an s reg 1998 ml320 auto petrol. When driving along about 45 mph a triangular warning light comes on in the middle of the speedo and the car seems to go into neutral. I can rev the engine but no traction. This happens for a few seconds then power is restored. It is not the limiter or cruise control as I have made sure of that. Any ideas? Thanks
October 23, 2013
  Followup from the Pelican Staff: I'm guessing but sounds to me like the traction control is detecting wheel slippage and closing the throttle until the computer feels traction is regained. Check for wheel speed sensor codes in the ABS system - Kerry at Pelican Parts  
Shane Comments: OK, I have a 97 c250 td auto, runs sweet other than occasional random changes, mainly from cold when cornering left. Now to me that suggests low fluid, so I have bought a dipstick frmo ebay and according to the instructions that came with it, it was about 300ml low on fluid. However,last night I lost drive completely for about 10 secs after I pulled in to allow an ongoing car to come through, car passed and I tried to pull back out and there was nothing there, went through the gears and it was fine for the rest of the journey. Any ideas? Also, every other auto I have owned the fluid level is checked with the engine running and in drive after being shifted through all gears, according to the blurb that came with this stick, it needs to be in park to check, does that sound correct? Thanks in advance.
October 22, 2013
  Followup from the Pelican Staff: Yes check in park with the engine running at about 30 to 35 degrees Celsius. If you have a computer controlled transmission (I can;t tell because I am from the United States and Mercedes did not sell the C250TD here) check the electrical connection at the transmission and the control unit for oil contamination. - Kerry at Pelican Parts

TG Shepard Comments: 2003 ML320 3.2L Kickdown Cable Leak at Transmission.
Is it necessary to remove the transmission to replace the O'rings on the cable housing?
I suspect the cable goes deep into the transmission. The O'rings need to go over the cable. It has a moderate standstill leak on the entire casing of the kickdown cable body held onto the back of the transmission with one bolt.
I am hoping the broken motor mount on the drivers' side did not cause the kickdown housing to crack. Have you run across the scenario before?
October 15, 2013
  Followup from the Pelican Staff: No but anything is possible.You probably do not have to pull down the whole transmission but you will probably have to remove the valvebody and linkages at the kinkdown cable to pull the o-rings off? - Kerry at Pelican Parts  
Mercer Comments: Hi, I do really hope that you will be able to help me, I have a Mercedes 1998 w202 c250td auto. I was busy on the dyno tuning the car with a Dastek Unichip, and the carpet at the back in the engine bay started to burn, engine is fixed all the wires that got some damage, the engine is still running perfect but it stayes in 1st gear auto it doesn't kick over to 2nd,3rd so on, when I put it in D sometimes it would like not select the the gear or when it does it kicks in and same with R.... Now I did a diagnostic test with a Launch on the ETC-Electronic transmission control unit and the two faults that it tells me is, 010 Valves supply voltage and, 106 Sporadically Valles supply voltage... I know the ETC is at the passenger feet.. What wire is the power supply to the transmission valves..??? Is there any transmission wiring diagrams that I can get somewhere... Please and thanks in advance....
October 14, 2013
  Followup from the Pelican Staff: You need to purchase one of our repair manuals on the car and check the power and ground supply wires to the ETC control unit. The ETC control unit supplies power and ground to the shift and pressue control solenoids in different combinations in order to shift the transmission whioe going down the road. The transmission control unit probably woke up while you were programming the engine control unit a got daomamged - Kerry at Pelican Parts

Gonzo Comments: Hi, I have a 1998 Mercedes S280 W140, this engine did not go to USA I assume.
I am sure it has the722.6 auto box.
My question is on two occasions I have been on the freeway and used kick down then suddenly lost all drive, scary to say the least when your in the fast lane !

Got to the kerbside switched off restarted and all is fine, another symptom is slight jump from 1st to second.

Any ideas, can much be investigated without box removal Thank.s in advance for any reply Gonzo
October 7, 2013
  Followup from the Pelican Staff: Well Gonzo the safest thing to do is get someone or some tool to pull the codes out of the transmission computer to find out what the symptom is. These transmission are known for having bad conductor plates and the speed sensors go bad. This may be your problem but it could also be transmission fluid "wicking" up the wires to the transmission control unit. Check and clean the connectors at the control unit. Of course there are many possibilites but these are commong. - Kerry at Pelican Parts  
Bear Comments: Hello, I have a 2002 Mercedes E320 with about 90,000 miles on it. Last weekend I was driving down the expressway and I heard a beep and noticed that the ABS and BAS lights were on and a message to take it to Mercedes Service. Also before I reached my destination, the transmission seemed to be slipping. Once I reached my destination, I pulled in forward to park it and tried reverse to back into a parking space but it would not respond. I had to push it. I tried turning the steering to the left and right and this cleared the Lights now check engine light is on and now the transmission will not shift above 2nd gear 50-55mph max at 5500rpm. Can you please Help?
Thanks in advance for any assistance you can give.
October 6, 2013
  Followup from the Pelican Staff: I'm sorry bear but you may have a bad transmission. Some common problems with this unit is transmisson fluid "wicking" up the wires to the control unit, bad conductor plate (has speed sensors in it) or low transmission fluid. You are really going to need someone to pull codes out of your engine and transmission computer. Keep in mind there are many possible failures I just gave you the common ones. - Kerry at Pelican Parts  
freddy Comments: I have a 2002 c230 kompresor what kind of service will it need at 100,000 miles?
October 3, 2013
  Followup from the Pelican Staff: All this information can be found in your owner's manual. THis is a major service which will include replacing your spark plugs. Other items that need to be replaced are brake fluid every 2 years, coolant every three years, and every 4 years or 30,000 miles replace your air and fuel filter. This is all based on if you followed the maintenance schedule in the bool and not the FSS. - Kerry at Pelican Parts

When if fails, on the dashboard the gear indicator as well the S/W indicator do not show.
Where should be this fault located? Gearbox connector plug?

October 3, 2013
  Followup from the Pelican Staff: I have see oil in the connector at the gear box and "wick" up the wiring to the control unit under the passenger side floorboard. Clean connectors with electrical contact cleaner. Clear codes and disconnecto the battery for 15 minutes and turn ignition key on with the engine off for one and a half minutes after you have reconnected the battery. You may have problems in theocnducti=or plate inside th transmission as well.- Kerry at Pelican Parts

  Followup from the Pelican Staff: Try unplugging the electrical connector at the transmission and see if the vehicle will move forward. You will only have 3rd gear but you need to know if the car will move. If not you have a bad transmission. If it does move you have an electrical problem. - Kerry at Pelican Parts

  Followup from the Pelican Staff: We do not have the C200 here is America. I doubt it is electronically controlled but look of a large electrical connector around the perimeter of the where the pan mounts. If you have a large electricla connector rotate the lock clip, unplug it and see if there is oil in the connector (leaking) If it is not electronically controlled check that the shift if moving inside the transmission and you may have to try swapping or installing a rebuilt valve body inside the transmission - Kerry at Pelican Parts

September 2, 2013
  Followup from the Pelican Staff: I would start by checking the fluid level and condition. Some of these vehicles had an issue with the wiring harness at the transmission, it will wick fluid up the harness to the control module, causing a similar issue. Check if your control module has fluid at the electrical connector. - Nick at Pelican Parts

Alan_1967 Comments: Dear Sir,
I have a 1997 Mercedes S500. The transmission does not respond to engage quickly when I slow down to about 10 Miles an hour then step on the gas to go. It kind of jumps after it engages. This usually happens when the car has warmed up and when it is hot outside. Also it shifts too early to third gear when only up to about 35 - 40 miles
I have changed the transmission oil and filter with same results. Nothing has changed.

Any Suggestions please?

  Followup from the Pelican Staff: Do you have any codes in the transmission computer? These transmission have a conductor plate inside that goes bad but you usually get codes from this problem. - Kerry at Pelican Parts  
Ron Khan Comments: Hi, I have a 1999 E320 with 190k miles on it. I want to change transmission fluid because it is black and smells burnt. Car is running okay though. Transmission shop guy said don't change. It might not work after new clean oil. I am confused now. What should I do??
August 26, 2013
  Followup from the Pelican Staff: There is some merit to what your transmission guy says. Clean fluid will fix solenoids that are sticking as a result of dirty fluid but nothing is going to help with the clutch material that has already worn off the clutch plates. If you are going to change the fluid do a "flush". This is like a transfusion. Old fluid is pumped out and new fluid is pumped in. To drop the pan and replace only what was drained in the pan will only changed less than half of the fluid in the transmission. - Kerry at Pelican Parts  
MGM AUS Comments: i have exactly same problem as "nigel merc" from 5th august... '98 E240 doesn't respond to accelerator for 2-3 seconds . RPMs do not increase during that time so your Kerry's advice was it's likely to be an electronic throttle problem . Is this easily replaced or repaired ? Is it expensive ?I appreciate your excellent column .
August 19, 2013
  Followup from the Pelican Staff: If the car has electroic throttle (EA) (cars with traction control) it can usually be replaced without taking off the intake manifold. You really need a Mercedes Benz capable scan tool that can go into the engine management computer and the EA computer. You can try disconnecting the battery for 15 minutes or so and turning the key on for 90 seconds after reconnecting the battery. That may reset the throttle if the problems is not a hard fault. - Kerry at Pelican Parts  
Ken Comments: 1995 E320, has normal dipstick locked in place just as the cap you show. Do I measure the oil level with the lock up, so the dipstick goes all the way in, or down, so the end of the lock hits the top of the tube, limiting dipstick travel by an inch or so? I assume it is with the lock up and out of the way. Let me know as I know fluid level matters a lot.

ezslc Comments: I have a 1997 e420 and this was the per-inspection codes and notes?

"Engine sounds good except for long cranking after
sitting for a while. Has the following historic codes:
*P1580 M16/3 right EA/CC/ISC actuator, located on left of enigine
*P0455 purge control system, major leak, or voltage supply of component
B4/3 fuel tank pressure sensor."


he also mentioned this:

"Transmission fluid looks dark and dirty, do not advise
servicing transmission unles it has been serviced before"

If it has been serviced before would it be bad to service the transmission fluid again if its dark and dirty?
August 15, 2013
  Followup from the Pelican Staff: The long crank issue could be related to the P1580, the fault code points to a problem witht he electronic throttle module. A lot of time this is a faulty throttle module

The P0455 is a major evap leak. This is a large fuel vapor leak in your evaporative emission system. This could be a leak or a faulty fuel tank pressure sensor. I have seen it go both ways.

Some shops do not like to service transmission fluid when it is drity. There is some fear that the transmission will develop an issue once new fluid is introduced.

August 13, 2013
  Followup from the Pelican Staff: Sounds to me like either your ESM (Electronic Shifter Module)or your transmission position switch are not functioning so the ME (Motor Electronics) does not know the vehicle is in park and therefore will not let it crank. Check your fluid level in the transmission. Also try disconnecting the battery (you will lose your radio station presets) and reconnecting it after 5 minutes. - Kerry at Pelican Parts  
nigel merc Comments: I have a 1998 E430.it starts and idles perfectly. if u press down the accelerator pad the engine only response after a few seconds. it therefore takes off very slowly but once it starts moving everything seems normal. speed limiter no longer works, just beeps and writes --. the cruise control is OK. what could be the problem?
August 5, 2013
  Followup from the Pelican Staff: It sounds like an electronic throttle problem not a transmission problem. Does the rpm increase when you step on the gas but the car not move? That's a transmission problem. If you step on the gas and the engine rpm does not increase right away that is an electronic throttle problem. - Kerry at Pelican Parts  
nrj1084 Comments: The 1996 E320 and E300 still had the old 722.3 4-speed automatic, not the newer 722.6. Is the service interval and procedure the same on the '96 models? I know that the article description says that the tutorial above applies to all 1996 W210 models, but I wanted to make sure that was indeed the case, because it is sometimes easy to forget that the first-year models used a carryover tranny from their W124 predecessors.

Could that be overfilled and what's the correct action if yes?!
July 31, 2013
  Followup from the Pelican Staff: NO, over filled is not the issue.
Low oil level might fit your description.
The failure may be coincidental, as there are other very expensive possible causes.

scotrvmarine Comments: Hello,

I am confused. Concerning the 726 transmission.
This is a response I got earlier.
"Yes, it is "possible" replacing the defective "A/T Wiring Harness Connector" might repair your shifting issue.
http://www.pelicanparts.com/cgi-bin/ksearch/pel_search.cgi?SUPERCAT_FLAG=Y&make=MBZ&please_wait=N&forumid=&threadid=&command=DWsearch&description=2035400253&I1.x=8&I1."

So I ordered the transmission adapter wire plug. Reviewing the other posts I found this.

" Also, I don't want to buy the whole connector at $30 from the dealer. I was thinking about pulling out the piece and bringing it to Home Depot to see if I can get O-rings that would fit. Would this be a dumb move because of temperature thresholds and such? Thanks
July 22, 2013
Followup from the Pelican Staff: Sorry, your idea will not work.
The connector fails by leaking through the wires, not the O-rings."

Did I order the correct part? Is what I need a dealer only part? I didnt get new wires just the adapter plug with the o rings. Is what I need the wire harness and plug going to the tcu?

Thanks for all your help.


July 23, 2013
  Followup from the Pelican Staff: You ordered the correct part...
The response to "ilen" should be ignored, as this person wanted to re-use the old adapter plug, thinking their leak was only from the O-rings.

MB superseded this part (so many times) because:
The "wire pins" molded / cast into the plastic adapter plug, leaked transmission fluid around the PINS directly into the external wire harness.

Long-term transmission fluid leaking in the external wire harness flows through wicking action, up to the transmission control module (wrecking it).

My three safety rules for this adapter plug:
#1. If it is leaking, replace it with the newest level.
#2. If you are doing related transmission service, replace it with the newest level.
#3. If cannot prove beyond ANY doubt that it has already been replaced, replace it with the newest level.

Scot Comments: Hello and thanks for your great website.
I have a 1999 E300D. Will this transmission fluid change procedure be the same? Also, my transmission seems to be stuck in one gear. In other words does not shift up or down. I have reverse. Is it possible that it is the harness connector if it is leaking? Would just changing the connector correct the problem or does it cause damage to the TCU?

Thanks again,
Scot

July 10, 2013
  Followup from the Pelican Staff: Incorrect fluid level will lock the transmission into safe mode or lock out the shifter.
The MB dealer STAR diagnostic scan tool is required to unlock, clear codes, and probably reprogram the transmission modules.

Transmission seems to shift OK; I still was unable to get a reading on the dipstick, it's smudged with oil to the top of the plastic part! What could I be doing wrong? Could I really have overfilled the transmission with 9.5 liters / 10 quarts? Why is there no defined ATF volume?

Thanks!
June 30, 2013
  Followup from the Pelican Staff: These are very touchy, you might have filled it to quickly.
From your description, it sounds like the system is over filled.
Excess fluid needs to be removed, before the transmission is damaged.

This
"Why is there no defined ATF volume?"
is a question for Mercedes engineering.

Jens Comments: Hi, excellent instructions and photos! However, I attempted the trans. oil change on my 1997 E420 and failed miserably when I tried to fill it. The ASR light and the ABS warning light came on the left wheel only span intermittently; I could not get a read on the dip stick starting with 5 quarts it only showed oil smudged to the top of the plastic part new dip stick supplied by you, as all other materials; I couldn't get it to register more than 70 degree Celsius with a Pyrometer even after several hours of idling and revving the engine with tranny in various gears and park. I ended with 9.5 liters or 10 quarts in the transmission hoping that that wouldn't be too far of the mark...? Other than shooting the car what do you recommend! Thanks!

scot Comments: Hi! New to your site, but find it very informative and VERY user friendly! Thanks for that.
Question about my 2002 S500..Transmission. Lately, its been shifting very erratically, sometimes going into neutral on its own while coming to a complete stop. I can shift manually, and its all good. I do not remember doing a service on it for over 150,000 miles, as the whole ....life long sealed transmission thing that I took seriously. But, the oil as I have seen it is VERY dirty and I'm wondering if its OK to do a flush and filter change? Also a connector change as I have been told leaking oil can get in there and cause trouble as well. Would you happen to have any diagrams of the transmission, from the valve body, conductor late, solenoids etc? I'm interested in how it all fits in there. Also, being told recently that we can now only get a new valve body, if needed, from the dealership, as well as the programming of it? Is this true, and any common sense reasoning behind this move by Mercedes? Can I clean it out myself without damaging any thing important?
Will be ordering my filter kit, connector and fluid over the weekend from you, and wanted to make sure I was starting in a good place. Thanks again for all your great info!

Replacing the transmission fluid every 100,000 miles is wise.
Ignore the Life long sealed transmission claim, it is wrong, and MB now suggests fluid services for these units.

As it is VERY dirty, I suggest a flush and filter change.

Harleyman87 Comments: Hi, I have 1993 500sel I took it experienced mechanic fixes Mercedes and had rear seal replaced & filter and pump changed. Now transmission oil is keep on leaking from either seal or bottom dipstick screw. I have taken it back 5 times back to mechanic. He has replace pan gasket 3 times and all the other seals have been replaced. PLEASE HELP, Do you think they are tightening pan screw too much and messing up gasket, But I also observe it's leaking from dipstick screw seal which has been replaced 3 times. I spend over $2k on this repair alone and still unable to drive it. What should be torque for pan screw & dipstick bolt. Thanks

  Followup from the Pelican Staff: I suspect this leak has been mis diagnosed.

One of the most common and difficult to diagnose leaks is the transmission pump O-ring failure.

The pump O-ring leak typically travels along the oil pan gasket or dipstick area.

The transmission must be removed, and partially disassembled for this repair.

Bristol Danny Comments: I have a 2003 C200K Merc. At times when pulling away the auto gearbox does not change up a gear but just stays in a low gear and revs. I find that by putting it into neutral and then back to drive it is ok. Is it a possibility that it is low on transmission oil or could it be something more sinister.
April 3, 2013
  Followup from the Pelican Staff: Start by assuming low fluid, because everything else is higher cost.

bristoldanny Comments: When pulling away from standstill my C200k 2003 auto gearbox sometimes sticks in first gear and revs and will not go up a gear. the only way to stop it is to put it into nuetral. is this a lack of gearbox fluid or something more sinister

cc260E Comments: Great DIY job explaination,

Many thanks

Maybe I misread it but I would like to know the reference of the dipstick to buy it from Mercedes.

Thanks

  Followup from the Pelican Staff: You are welcome.

Dipstick
MB# 140589152100

When the transmission is cold the oil level indicator must be between the "min" and "max" mark at a transmission oil temperature of 25° C.
The exact oil level must be between the"min." and "max." mark at 80°C (transmission oil temperature).

nick Comments: my 1991 sl500 will not go into reverse unless i turn off the engine , any thoughts
March 26, 2013
  Followup from the Pelican Staff: The most common causes of automatic transmission reverse failure.

Improper fluid level.
Fluid filter damaged or plugged.
Transmission shift cable mis-adjusted.
Improper band/clutch application pressure.
Direct/Reverse servo piston seal cut or leaking.
Reverse clutch burnt or worn out.
Main control assembly gaskets damaged or bolt out of torque.
Main control separator plate damaged.
Pump assembly bolts out of specifications.

The only quick answer is diagnosis by a good transmission specialist or independent MB shop.

  Followup from the Pelican Staff: Typically that is a loose/damaged fuel cap, hose or line.
Your local Mercedes dealer will often print off the workshop pages you need.
A full list of the parts is (I am guessing) several thousand USD.
We have all of the parts.

  Followup from the Pelican Staff: P0455 gross leak is most often a loose fuel cap or broken hose/fitting.
You can build an adapter from a fuel fill cap, pressurize the tank between 0.5 and 1.0 PSI, and listen for the hissing leak.

Ran car shifted gears and then drove 3 miles lost drive completely . Have drained both box and torque refilled still no drive. Any help greatly appreciated cheers

  Followup from the Pelican Staff: These all transmissions can be finicky at times. I have heard of this happening before with some of the older BMWs. I would recommend that you verify the fluid level in the transmission when it's warm and running and on flat level ground. You also might want to try using a different viscosity of fluid. At your local auto parts store you should be able to find long life transmission fluid that might work a bit better. Hope this helps. - Wayne at Pelican Parts  
Tat Comments: Hello I own a 2000 Mercedes cl500. Chassis w215 v8 5.0 liter . My transmissions is leaking. Should I just add oil And replace a gasket or do the whole flushing and refilling the oil? Please provide instruction I would really appreciate it thanks!
February 8, 2013
  Followup from the Pelican Staff: With a leaky transmission it could be a minor issue or a major issue. First I would make sure that none of the transmission lines are leaking and that the leak is actually coming from the transmission case itself. Then I would clean off the bottom of the transmission and check to see if I could tell where the leak is coming from. If the leak is coming from the gasket that holds on the lower pan, then you should be able to remove the pan change the fluid and replace the gasket fairly easily. If the leak is coming from somewhere else then it may be a more involved procedure. I believe that you can also try using a high mileage transmission fluid that is less likely to cause leaks on older transmission. I haven't used this product myself but if you transmission is leaking it's probably worth a try. - Wayne at Pelican Parts

josphat matare Comments: my Mercedes e320,1996 model shows exhaust is overheating on the dashboard,could that contribute to engine overheating and what could be the probable cause and needs to be done.
Thank you in advance.
December 11, 2012
  Followup from the Pelican Staff: Exhaust overheating:
This needs to be addressed quickly, by a qualified professional mechanic.
Warning, Danger: In extreme examples of this issue "THE VEHICLE CAN CATCH FIRE.
Here are examples of glowing metal, and what temperature your vehicle is exposed to.
http://www.marshallarts.co.za/temptable.htm
http://www.simplytoolsteel.com/images/Temperature-color-chart-large.jpg
http://www.m4040.com/Knifemaking/PICTURES/Tutorial/GlowChart-sm.gif

The main cause of converter overheating is excess fuel in the exhaust.
The fuel enters the ceramic block and burns there, creating excess heat.
Temperatures rise to 1,500° F or higher.
The catalytic - ceramic matrix fractures, melting in upon itself, blocking the exhaust system further + trapping more heat.
This is a self-destructive cascade event known as "converter melt-down".
The over fueling issue must be repaired BEFORE replacing the catalytic converter or "converter melt-down" will happen again.

Army Comments: When turning the crankshaft by hand with your 27mm socket always turn the crank in the same rotation in which the engine runs. In this case if you are standing in front of the car looking towards the back; you turn the engine in a clockwise direction.

Do not forget to remove your ratchet handle and 27mm socket before you start your engine!

  Followup from the Pelican Staff: Thank you.

We are reviewing the DIY, to edit in your suggestions.

Both are important.

Again, thank you.
