Have just found out that my manual 924s (1987) has never had the transmission fluid replaced. What is the best/ current standard fluid for my transmission? The only type available on pellican parts is the "swepco 201 80w90". Would that be good or is there something better?

Swepco is the best option for the Audi 016 transaxle.

Just to be clear, that is the transaxle in the 87 924s? I'm not familiar with the part numbers/types.

Yes, its an Audi 016 transaxle (similarly used in the Audi 4000/5000/200, etc.):

Thanks, this helps a lot. Do you know how I'd tell if I have the LSD version or not without checking the serial number?

The option tag in the trunk (assuming the transaxle is the original one) behind the trunk carpet along the edges.

Another option is to lift both rear wheels, put the car in neutral and turn one wheel. If the opposite wheel turns in the same direction, then you have a LSD. If they turn in opposite directions then you have open diff.

The Clark's garage doesn't list the QK trans as an option for the 924s. Oh well. At least I know now. Appreciate the help.

Since you mentioned Pelican------Redline MT90 is probably THE best.

The Redline MT90 isn't as good in the 016 when compared to the Swepco, its still better than old, dirty oil.

How are they different? Or how do you determine what works better?

Well, I put Redline in the "dogleg" Porsche 915-based box on my 924 and it made a huge difference in shift quality.

I put Redline in the Audi 016-based box in my 944 turbo and the shifting was non-existent when cold, but worked just fine once warmed up.

I'm going to put the Swepco in since my research indicates that should help solve some of the issues I'm having now. Though to be honest, this box has over 200K on it, so there's not much I can do that won't be a stalling effort at this point.

It was just remarkable how large a difference there was in cold shift effort from the old fill and the Redline on that gearbox, especially after the gains found on the other gearbox.

If you do a little searching here and on other 944 forums you may find some strange results when using Redline on those gearboxes, its a bit mixed to be honest.
