In my 79 Trans Am. I've got it running decently now. The Borg Warner 4 speed super T10 does not down shift that well. To go down into 1st the car practically has to be just creeping along. I'm guessing the factory gear oil is still in there. I added a bit of Maxlife ATF (12oz out of 40oz capacity) to thin it down and it improved some.
So what kind of fluids should I try in there?
1. I just picked up some Pennzoil synchromesh
2. I have some CVT fluid
3. various ATFs Dex, Merc, Maxlife
4. what engine oils should I try?
5. various additives such as Lucas trans fix
Longevity is not a concern as this is just a toy that will be driven maybe 1-2 k miles per year. So I seriously doubt that anything I put in will mess it up.
Shift quality is the desired result.
