Excellent Product
The full 1 gallon bottle filled the transmission with a little to spare--maybe half to 3/4 of a quart.

Swepco figured it out
While there is no such thing as a miracle cure, I found the shifting in my 83 911sc to be smoother and more precise in feel after changing to Swepco 201. Still too early to for a dispositive result, but so far so good.

Perfect stuff for a 901
Simply the best for your 901 4 or 5 speed.

awesome gear oil.
This is a very high quality gear oil.
Just using this oil makes the shifting seem like new again.

Good stuff!
Short of a G50 transmission upgrade, the Swepco can be a cheap solution to your shifting problems. It won't perform miracles, but it certainly helped my '79 SC.

Smooth shifts, but not for cold climates
It did seem to make my 987 Boxster shift more smoothly, but then winter came. In the cold weather it is hard to shift during the first few minutes of driving. For this reason I think I will switch back to a multi viscosity synthetic.

A Believer
I am convinced that my 1986 911 shifts better with SEPCO 201 gear lube on board.

Slicker than hair oil
Or so my grandfather used to say. The fluid did make a slight difference in the shifting. Assuming it protects as well as everyone says, I would purchase again.

Great Stuff!
Swapped out my current fluid for this and my transmission is much smoother than it was previously. I was having trouble getting into 1st and Rev, but now most of those issues are gone.

Good Stuff For Your Picky Transaxles
Been using this for years, really quiets down noisy gears and synchros.

Smooth operation
Just flushed out the old Swepco 201. 25,000 miles and many track days. Just a small amount of metal whiskers on the magnetic drain plug. Which I think is great for so many miles. New fluid in; you can feel it is a little smoother than before. It was time.

Is it a bad pinion ring or bad transaxle oil?
Recently replaced the oil in my transaxle on my NA 944 with Swepco 201 and the howling sound that had been diagnosed as "a bad pinion ring" went away.

Immediate Improvement - 915 Transmission
Changed 915 transmission oil on my '84 Carrera because it wasn't shifting smoothly. The Swepco 201 product was highly recommended in the technical article and now I understand why. I saw an immediate improvement in shifting: shifts smoother, hesitates less, with less grinding. This product is "like butter!" Highly recommend at this point, although I've only driven the car 3 or 4 times since the fluid change.

Do NOT use in 1997 BMW 328i!!
Pelican Parts is irresponsibly marketing this stuff as liquid gold for all BMW manual transmissions, but if you use it in a 1997 BMW 328i or ANY BMW 1993 - 1997 it's more like liquid concrete. Reading these glowing testimonials, I paid the arm and a leg to upgrade my fluid. I came close to irreparably gumming up my transmission with Swepco by trusting Pelican for the product compatibility. After suffering nearly debilitating shifting, I did some extra research and found out that mid-90's BMWs use AUTOMATICDEXRON III transmission fluid in their manual transmissions. After flushing and replacing with the proper fluid $15.00 per gallon versus $60.00 my shifting is back to normal. Pelican should remove this listing for any incompatible models to aviod destroying their customers' cars with false representations.
Followup from the Pelican Staff:   For the early BMW transmissions (E30), BMW recommends SAE 80, WPI GL-4, MIL-L-2105 (non-hypoid type) fluid in the manual transmssions. For the differential, they recommend SAE 90, GL-5. For later E36 transmissions, some were indeed filled with automatic transmission fluid, and some with BMW MTF LT-1. There should be a tag on the side of the transmission recommending exactly what fluid to use. BMW also has "lifetime" fluid claims, which are not terribly good for the life of the transmission as they get up past 100,000+ miles. The Swepco product featured here has been used by many racers and enthusiasts over the years. Everyone seems to have a different opinion on the use of various motor and transmission oils - your preference may vary.

Transmission Fluid
Good pruduct, transmission seems much smoother.

Very impressed!
This gear oil is so far very impressive. It has a very sticky composition which I suspect will bode bell for my R&P and expensive gear sets.
