Guys, what transmission fluid are you all running for you manual users out there? I believe our weight is a 75w-90 (with the NON-slip versions preferred i.e. no friction modifier necessary). My research shows it's the exact same fluid for the transmission and differential (may be the same fill hole and drain hole...I'm not sure). Please let me know if I'm wrong on any of the above. And what is the "all wheel drive controller oil?" Thanks in advance for your responses!

 

Mobile 1 Delvac or Porsche Shell transaxle.

 

I use the Mobil 1 Delvac 75/90.

 

Thanks guys!

 

What about the front clutch fluid? My Porsche tech says it's different than transaxle fluid. Any idea, other than factory fluid, where to buy and what type?

 

A transmission specialist (they are members of this and many other sites) told me the Audi Transmission Oil (part# G 052 911 A2) is the exact same spec as the Shell Transaxle Fluid (part# 999 917 546 00). In fact, he said it was the same product, just re-badged under the Audi label! This would make perfect sense to me as I am in the marketing world and understand how products like engine oil, gasoline, peanut butter, etc. are commonly the exact same product, just re-badged under other labels. It's slightly less expensive than the Porsche branded oil (no surprise there). Just thought I'd pass this info along to the community!

 

This thread wasn't too popular, but for what it's worth, just got my turbo back today with the new clutch (from Protomotive) and the new Shell transaxle fluid and it is TWICE as good as the stock setup! The shifts are MUCH more precise and smooth, and the clutch is just as friendly as the stock setup, but bites harder! The clutch slippage is completely gone...couldn't be happier! Hats off to Todd at Protomotive...he really knows his stuff!

 

didn't know Todd offered clutch packages. Is it a sachs? what setup does he use?

 

It is a Sachs product.

 

great thread, does anyone know what the maintenance schedule is for a clutch fluid change? thanks for the help

 

Gbox transmissions (out of Colorado) told me the clutch fluid from the factory is VERY robust and doesn't need to be changed till 60,000 miles...I believe the owner's manual calls for 100,000 changes?? Gbox is extremely well respected on this and other forums. (See my earlier post for some very interesting data about the Audi fluid being the same fluid as the Porsche stuff...I received the Shell Porsche fluid and it is much darker than the Audi fluid...so, it's not the exact same, but probably meets the same spec...which is what Gbox probably meant anyways. The tranny shifts better with the Shell fluid than with the stock Mobil product).
