Cant seem to find recommendations for this. Mobil Synthetic ATF fluid or Swepco 714 (but what weight?) ?

No HTwo O

Can you purchase OEM trans fluid through places like Sunset Porsche? Are you going to replace the flter ($94) too?

I recently used M1 FS on my 993 tip.
There wasn't a weight to choose from - http://www.mobiloil.com/USA-English/...etic_ATF.aspx#

For the final drive (which will be changed shortly) I have M1 Synthetic gear lube - 75W90.

The tip shifted smoother and quicker than before. Easy DIY and highly recommended if it has never been changed before.

Haygeebaby,

Isn't the type of final drive fluid you linked to for Limited Slip differentials, hence the LS in the name. I don't think that's the type to use on a Tiptronic final drive (although it may work just fine). Just regular Mobil 1 Delvac 75W90 which is what many people use in the manual trans and front differentials on 964 C4 models.

Sorry for the late reply Ricardo. Just too busy these past few months.
Man - I just noticed the LS. How did I miss that ???
Need to check if it is okay to run API GL5 in the final drive.
Will update when I find out.

Just to let other users know, you want to use Mobil 1 Delvac 75-90 in the differential. Its hard to get, an you'll probably have to buy a whole gallon. The above picture is not the right stuff--it has friction modifiers in it for LSDs.
