A 1991 Chevy Camaro with a manual transmission needs Dexron II ATF fluid. It provides lubricant and cooling to the transmission.
A 1991 RS came with a World Class T5 transmission
is it an automatic, or manual shift?
I recommend syncromesh
The ONLY transmission that came in the 1991 350 Z28 was a four speed Automatic 700R4. IF it has a manual it was added by someone.
It could have an automatic or 5-speed manual
Should be a plug at the side of the transmission - fill to this level
3.9
dextron mercron
Dextron 3 automatic transmission fluid. now known as domestic automatic transmission fluid. Yes it is a manual but they used the same stuff. It just lubricates the needle berrings.
The transmission fluid capacity for a 1991 S10 5 speed manual transmission is approximately 3 quarts. This can be purchased at any auto parts store.
For ease of shifting, dexron transmission fluid is best. the other alternative is 80/90w gear oil.
I use Mercon Depends on make, model,............
