What oil should I put in my rebuilt Saab 900 '89 transmission?
The service manual specifies 10W30 or 10W40 mineral oil but is that even really applicable after 30 years? Oils have come a long way.

Using engine oil for a transmission just seems a bit retarded. Something made for bearings is not really the same as something for gears.
There are quite a few threads on saabcentral. Generally Mobil 1 10w-30 is suggested.
Did your pinion bearing go or did you lose synchros?

Pinion problems.
Changed a whole lot though. Synchros on 3rd and 4th gear, all seals, changed 4 bearings and so forth.

Vegetable oil should work fine.
