Default Trans Fluid

Good Morning, Question: What is a good transmission fluid for the MANUAL TRANS? All the auto parts stores around hear scratch their *** when you
tell them Manual trans fluid. Everything seems to says Automatic. GM 10-4033 is order only here. Trying to get this Vette off the hoist.

I have used Redline MT-90 and Royal Purple Syncromax transmission fluids in several C5's and C6's with no problems. I actually prefer the Redline oil to the GM oil.

If I remember correctly the manual trans uses Dexron III automatic trans fluid. Should be able to find this at any auto parts.

Hey Garry in Az. Those are great fluids. The only problem is nobody stocks it around here. I have to order and that takes 5 to 6 days.
All the good old speed shops are gone and the counter people here are from a younger generation. I think one day
soon the manual trans will be history.

You maybe correct however owners manual says GM 10-4033 manual trans fluid. Transmissions are a bit** to replace.
Thank you for your reply however.

OP said he wasn't going to use Amsoil. But I've used it on a T56 in the past and after 200 miles or so it got better and better. After 1000 miles it was shifting MUCH smoother. I plan to do the same with my Z06 next summer
