How to Maintain and Modify your new MINI

This article is one in a series that have been released in conjunction with Pelican Parts' new book, How to Maintain and Modify your new MINI The book contains 240 pages of full color projects detailing everything from performance mods to changing your brake pads. With more than 500+ full-color glossy photos accompanying extensive step-by-step procedures, this book is required reading in any MINI owner's collection. The book is due to be released in late 2015. See The Official Book Website for more details.

One of the easiest tasks to perform on your MINI is to change the transmission fluid. It's very important to make sure that the fluid in your transmission is at the proper level, otherwise your transmission will experience significant wear. The synchro rings and sliders all depend on a slick surface in order to match speeds when shifting. If your transmission is low on oil, the wear on these components will accelerate significantly. In addition, shifting the car will be more difficult. One of the first things that you should check on a MINI that is having problems shifting is the level of the transmission oil. In addition, keeping the differential and all of its associated gears well lubricated should also help increase your fuel mileage.

The transmission oil also helps to keep temperatures down inside your transmission. The engine is one of the primary sources of heat for the transmission as it conducts and radiates through and around the points where the engine and transmission are mounted. The transmission also creates heat itself as the gears and synchros turn within its case. Keeping the transmission fluid at its proper level helps to mitigate heat problems. Having a large reservoir of oil to spread the heat throughout the transmission helps to keep temperatures down. On some of the higher performance BMW transmissions, often there is an external transmission cooler installed that operates similar to the engine cooler.

The MINI Cooper and Cooper S specifies the use of 'lifetime' fluid. This means that the fluid is designed to never be replaced. I'm not a believer of lifetime fluids in general. In my opinion, the transmission fluid should be changed every 30,000 miles or about once every two years. This number is a rough estimate, and may vary depending upon your use of your MINI (track vs. street). There are many moving parts in the transmission, and they have a tendency to drop small microscopic metal particles into the oil. Specifically, the synchro rings wear down slowly over time, each time you shift. While the transmission bearings are not as sensitive as the engine bearings, they can still exhibit wear from these particles in the oil.

MINI Specifies the use of MTF-94 oil in the Getrag 6-speed. There seems to be some confusion about this oil and what exactly it is. Based on my research it appears to be a Texaco product re-branded for BMW and MINI. Attempts to purchase the oil at the local dealer resulted in them offering to sell me a transmission oil replacement service.  Based on my research, I have found an equivalent for many MINI manual transmissions through model year 2006, Red Line fully synthetic 75W/80W GL-4.  It has been the gold standard in BMW transmissions for years and is highly recommended to use in your MINI. At this time, Pelican Parts can supply you with either quart or gallon sizes (See Figure 1).

The MINI's manual transmission has two plugs for filling and emptying the transmission oil, located on the side and bottom of the transmission case. Note that the location of the fill/drain plugs are different on both the Cooper and Cooper S (See Figure 2 and Figure 3) If you are simply checking the level of oil in your transmission, start by removing the top filler plug on the side of the transmission (See Figure 4). This is the plug that you add fluid to. When you have the plug removed, take your finger, and stick it inside the hole, angle it towards the ground, and see if you can feel any fluid in there. Make sure you do this when the car is cold, and parked on level ground. If you can feel the fluid level with your finger, then your fluid level is about right, or perhaps will need only a little topping off.

If you cannot feel the fluid level, then you will need to add transmission oil to the case. If you are planning on changing the oil, then remove the small plug on the bottom of the transmission case (See Figure 4). It's a wise idea to try to empty the transmission oil when the car is warm, as this will help it will flow out easier. Make sure that you have a drain pan capable of handling at least 4 quarts of transmission oil. Check the fluid in the pan to see if you see any unusual metal pieces, or grit in the oil (See Figure 5).

While the fluid is emptying out, you can use this time to clean out the drain plugs. Using a cotton swab or a paper towel, carefully clean out all of the black debris and particles that may have found their way in there.

Replace the bottom (drain) plug on the transmission, but don't tighten it too tightly (32-50 Nm or 24-30 ft-lbs). These plugs do not have a tendency to leak (transmission oil is thicker than engine oil). If it does leak later on, you can always tighten it a little more. Now, add transmission oil to the case. The best method of doing this is with a hand operated oil pump. These are available from most auto parts stores and attach to the top of the plastic transmission oil bottle. (See Figure 6 and Figure 7) They work very similar to the liquid soap dispensers you find in most bathrooms. Pump the transmission case full of fluid until it just starts to run out the filler hole. R50/R52 MINI Cooper models up to 07/04 use 2 quarts of oil. From 07/04 to 2008, they use 1.5 quarts. The R53 MINI Cooper S uses 1.5 quarts up to 2007. R55/R56R57 MINI Coopers use 1.8 quarts and MINI Cooper S models use 2.0 quarts from 2008 on.

Replace the filler plug and clean up the few drips that might have run out of the hole. Re-install the top (filler) plug into the transmission and torque it to 20-30Nm (15-22 ft-lbs.) (for the MINI Cooper S, torque the top plug to 43Nm (32 ft/lbs.)).

(R50 Cooper): The procedure for changing the transmission fluid on the Non-S cars is the same, although the drain and fill ports for the car are different. On these cars, the drain and fill plugs are 17mm bolts instead of internal hex plugs and are also mounted on the opposite side of the differential. Be sure to replace the two copper crush washers that sit on the backside of both the drain and fill plugs (part number 23-10-0-630-776).

Shown here is the gold standard for BMW and MINI transmissions, Red Line MTL.
Figure 1

Shown here is the gold standard for many BMW and MINI transmissions, Red Line MTL. This fully synthetic transmission oil is suitable for GL-4 applications. This oil is a great alternative to the factory oil and is available at Pelican Parts.

Shown here are the two plugs for the transmission on a MINI Cooper S with the 6 speed transmission.
Figure 2

Shown here are the two plugs for the transmission on a MINI Cooper S with the 6 speed transmission. The fill plug (green arrow) is above the drain plug (yellow arrow).

Shown here are the two plugs for the transmission on a MINI Cooper with the 5 speed transmission.
Figure 3

Shown here are the two plugs for the transmission on a MINI Cooper with the 5 speed transmission. The fill plug (green arrow) is above the drain plug (yellow arrow). The difference here is that the fill and drain plugs are on the opposite side of the transmission. The procedure for draining and re-filling the transmission is identical.

If you are only checking the transmission fluid level, remove only the top plug.
Figure 4

If you are only checking the transmission fluid level, remove only the top plug. The fluid level should just be at the bottom of the top plug hole.

It's a good idea to let the car warm up or drive it around the block a few times to allow the fluid inside to warm up.
Figure 5

It's a good idea to let the car warm up or drive it around the block a few times to allow the fluid inside to warm up. This will help it drain from the transmission. Remove the lower drain plug after removing the top plug.

Be sure you have a drain pan of at least 4 quarts capacity prior to draining the tranny fluid.
Figure 6

Be sure you have a drain pan of at least 4 quarts capacity prior to draining the transmission fluid. Be sure to have paper towels on hands to clean up any spills.

Shown here is the drain plug removed from a MINI Cooper with the 5 speed transmission.
Figure 7

Shown here is the drain plug removed from a MINI Cooper with the 5 speed transmission. A magnetic plug is used to collect metal shavings in the transmission that occur when the moving parts inside wear. Changing fluid often helps prevent this. Wipe the drain plug clean before re-installing with a new crush washer.

After the fluid has completely drained from the transmission, replace the drain plug.
Figure 8

After the fluid has completely drained from the transmission, replace the drain plug. It's a good idea to use a hand-operated fluid pump to fill the transmission with the new fluid. There isn't a lot of space to fit a bottle up there so the hand pump is a great alternative.

Shown here is the tube from the fluid pump entering the fill port on the transmission.
Figure 9

Shown here is the tube from the fluid pump entering the fill port on the transmission. (green arrow) Keep pumping until fluid just starts to flow out the fill port. Then carefully remove the fluid hose and re-fit the fill plug back into the transmission.

  Followup from the Pelican Staff: Detach the cables from the transmission. Once removed, does the shifter move easily? - Nick at Pelican Parts  
Leigh Comments: 2003 Mini Cooper S 130,000m. I have alot of slack in the drivetrain. I'm a fairly accomplished mechanic and its definately not clutch slip. When in gear with 1 front wheel off of the ground the wheel will rotate about 15 degrees. There is obvious slack in a coupling inside the transmission. The constant velocity joints are tight, the movement is obvious at the point the driveshaft enters the transmission. It also makes a slapping noise in the transmission. The gears shift well and the front end is otherwise tight. Ideas?

Northbarts Comments: My 2002 MC with approximately 100k has developed a growling noise in the manual 5 spd. transmission. I have never serviced the tranny. Could the noise be caused by low oil level and do you think that an oil change with Redline MTL might resolve the issue? Am I about to lose my transmission?
June 12, 2014
  Followup from the Pelican Staff: It could be from low fluid, I would use MINI fluid myself. Keep in mind, a growl may be a faulty bearing. Check the fluid for metal debris when draining. - Nick at Pelican Parts  
miguel Comments: Can I put royal purple in my trans . I have an 03 cooper s
April 14, 2014
  Followup from the Pelican Staff: I prefer MINI fluids. I have n experience with royal purple. That is a question for your local MINI dealer. - Nick at Pelican Parts  
Howie Comments: I have a 2005 Mini Cooper S 6 speed. It has been getting consistantly louder the higher the speed and lower the gear. My first thought was tires, but am thinking more like drive train issue. Could this be caused by the need to change the fluid or do you have another possible cause. I appreciated the help.
April 9, 2014
  Followup from the Pelican Staff: My suggestion is to pinpoint the noise. if it sounds like it could be related to wheel speed. Inspect tire and wheel bearing condition. - Nick at Pelican Parts  
jown.iv Comments: would just like to point out, under "tools", 14mm hex key socket is listed. on an r53 cooper S, it is an 8mm hexy key socket. fortunately, i picked up an entire metric set of hex key sockets, rather than just the 14mm, otherwise i would have been pretty irritated.

other than that, i appreciate the write up. worked out well. thank you.

sebs Comments: What type and how much transmission fluid would I need for a 2005 Mini Cooper R50 5 Speed, Can I use 75W/80W GL-4 ?
February 25, 2014
  Followup from the Pelican Staff: The fluid amounts are listed in the article:

http://www.pelicanparts.com/techarticles/MINI/30-TRANS-Manual_Transmission_Oil_Change/30-TRANS-Manual_Transmission_Oil_Change.htm

Replace the bottom (drain) plug on the transmission, but don’t tighten it too tightly (32-50 Nm or 24-30 ft-lbs). These plugs do not have a tendency to leak (transmission oil is thicker than engine oil). If it does leak later on, you can always tighten it a little more. Now, add transmission oil to the case. The best method of doing this is with a hand operated oil pump. These are available from most auto parts stores and attach to the top of the plastic transmission oil bottle. (See Figure 6 and Figure 7 ) They work very similar to the liquid soap dispensers you find in most bathrooms. Pump the transmission case full of fluid until it just starts to run out the filler hole. R50/R52 MINI Cooper models up to 07/04 use 2 quarts of oil. From 07/04 to 2008, they use 1.5 quarts. The R53 MINI Cooper S uses 1.5 quarts up to 2007. R55/R56R57 MINI Coopers use 1.8 quarts and MINI Cooper S models use 2.0 quarts from 2008 on.

Salzundpfeffer Comments: Do you recommend any additives like SLICK5000, graphite based - any experience with them - clumping or clogging. I know OEMs do not recommend them, just curious if there is some real world experience.

  Followup from the Pelican Staff: I have no experience with it.

I opened a post in our forums. A Pelican community member may be able to answer your question. - Nick at Pelican Parts
 
Prodigium Comments: How do you get underneath a Mini on level ground, take the plug out to check the oil level? Most of us have to do this with the cars front wheels on ramps and that will give a false full reading of the level. Filling with the fronts on ramps will result in a fill that isn't filled. Any suggestions? If I fill with the cars rear wheels on ramps it will overfill, maybe a pint or so, but is that bad?

  Followup from the Pelican Staff: I would suggest getting all four wheels off the ground. This can be done with jack stands, or a combination of jack stands and ramps. - Nick at Pelican Parts

DavidR Comments: 2007 base Cooper - I haven't looked underneath yet, but there's no need to remove the subframe, right? That is, I can reach the plugs OK - assuming that I have the right wrench - with the subframe in place?

Great articles. Thanks! My 07 has 80K on the clock and is getting to the age where I need to keep a closer watch on its needs.

Dando Comments: Can I just ask.. Once the Drain and fill plugs are removed, when fitting them back on 6 speed gearbox do you need to replace the washers? If so does anyone know the size of the crush washer needed? Thanks in advance.

Bojangles Comments: As an engineer I would like to clarify the incorrect statement above.
Multigrade oils are for comparing viscosities at the same temperature.. and EVERY automotive oil gets runnier at higher temperature.
a 10W30 oil means that when at room temperature, the oil has a viscosity of a 10 weight oil, and at operating temperature it has the viscosity of a 30 weight oil AT THE elevated temperature. 30 weight oil at operating temperature is still less viscous runnier than 10 weight at room temperature.
There is a lot of confusion out there. For sure the transmission oil 70W90 is definitely easier to drain when warm.

elio Comments: Really interesting, a good number of mini owners doesn't know that they should change the transsmision fluid even if they minis have manual transmission.

Chris Comments: Nice write up on fluid change. One comment regarding Cooper non-S with 5spd Getrag transmission late 2005 and 2006 R50s. The 5spd Getrag fill and drain plugs are the same as shown in Figure 2 for the S transmission also Getrag. Recently changed trans fluid in our '06 R50 with 5spd Getrag...very easy and quick procedure.

Lee Comments: Great article. One typo to note: in paragraph 6, the phrase "...the car is warm, as this will make the oil more viscous...". When warm, oil is *LESS* viscous lower viscosity.
