E36 323i Manual Sedan

I replaced my transmission fluid in my Manual E36 (Getrag with ATF stickers on side of transmission) with this after reading lots of people raving about it on the forums. Downshifting into 1st and 2nd became much harder. I switched back to a generic Castrol Dex III ATF and everything is smoother again. Many have said this works well, but it didn't for me. Might be a gretrag vs ZF transmission thing?

Better Than Royal Purple Or Oem

I have tried other oils and my e46 manual transmission and this provided the smoothest shifting even in cold temperatures.

Perfect For A/T Drain And Fill

Do not believe the hype about lifetime fluids. All fluids will die with use and wear overtime. Flush out your dirty and burnt automatic transmission fluid before you do serious damage to your transmission.

Good Tranny Fluid For Your Money!

I bought about 6 bottles of this to change the old, neglected tranny fluid in my B5 A4 Quattro. I was hesitant to use this fluid at first, however after doing some research and finding a thread with many, many, happy users logging many miles on the stuff, my worries subsided. Also, this stuff meets the requirements of Esso LT71141 (ZF's requirements for B5 Passat and A4 FWD and AWD TipTronic transmissions), so no need to worry about it wrecking your tranny! Not only is it synthetic, but it is also much cheaper than Pentosin or similar replacement tranny fluid and much, much, cheaper than OEM fluid. Buy 6 bottles so you can be sure you have for a tranny drain/refill and filter replacement. Make sure you follow the filling procedure found in the Bentley manual or other official sources. Then reap the benefits of having nice fresh tranny fluid and a smooth transmission.

Some of the reviewers above may have been rewarded for their positive & negative reviews. We don't hold anything back.
