Ok, here's the deal. I have a 85 trans am that I had the transmission completely rebuilt in and it had a B&M shiftkit installed at the time(I know, I know, but I hadnt heard anything bad about them at the time). Anyway, this was back in the 305 days. just got the car going again, but in the time the car was down(about 16 months) I put a corvette servo, larger boost valves, a B&M cooler, and Mobil 1 Synthetic. The car was only driven probably 3 or 4 months after the shiftkit until the motor went. It now has the 350 in the sig, along with a 3.45 posi rear and Potenza RE730 tires.

Now for the problem. I took it out for the first time and when I drove it it seemed to pull pretty good and it doesnt seem to rev up between shifts or anything(that I can tell so far because I have only driven it a few minutes), but it doesnt chirp the tires on the shifts anymore. It still seems to shift fine from what I can tell from driving it around the neighborhood other than not being as firm as I want at full throttle. I put a 3000 stall in it so I know that the shifts wont be as firm as they were at part throtle but that is fine. I reset the tv cable today and took it out for another quick drive but it seems to be the same.

I dont think it is a lack of power because I had a worn out LG4 before that wouldnt even lite the tires up from a stop and now I can lite them up pretty good from a 10+mph(speedo isnt wired up completely yet) roll.

Does anyone know what my problem is?

Thanks

Anyone? The only things really intearnal at all that I did was the corvette servo and boost valves. Could either of those if installed wrong cause these symptoms?

Also, I know you are supposed to check the fluid hot. Will it appear higher or lower on the dipstick when hot. I would assume higher since stuff tends to expand when hot, but am not sure. I havent got a chance to check it when hot yet because I have only driven it twice and didnt leave the neighborhood either time. I just wasnt thinking to check the fluid hot. It appears to right about at the full mark when cold. How much of a difference will there be?

I could really use the help. I just want to know if anything I have changed between the time I stoped driving it and now could have caused this. It shifted firm enough at WOT to chirp the tires until I stopped driving it and everything I have done should have increased the firmness of the shifts other than the stall, and I dont think that would effect WOT.

when we rebuilt my tranny, the first drive we took it shifted horribly smooth, but as i drove it more and the clutches obsorbed fluid, it started shifting harder, maybe you just need to drive it some, so just go put miles on it and if in a week its still smoothe, check back here

 

I was hoping it could be something like that. I have only driven it about a mile if that since I got the car back together. I still have to do a couple more things to the car and get plates back on it before it is ready for street duty though. Man I hope your right.

Hey, I drove it around a bit today and it seemed a little better. Then I came home and checked the fluid while it was hot. It was pretty low so I filled it up and it shifts awsome now.

Thanks
