I just got my 95 T/A, 383 D1SC running. I took it out for a ride today, with very little 1/2-3/4 throttle burst. No full throttle! Still working on finalizing the tune. Well, I was just cruising easy and the car will not go into 3rd or 4th. 1st and 2nd are fine, but when it chages to 3rd it just revs to the moon.. The tranny was rebuilt with a few "performance" parts a couple of years ago and has about 25K on it now. Tranny has cooler, Steel sprag, Kevlar clutches, and corvette servos, plus a Yank 3000.

Is my tranny toast or is it something else. I have scanned it and there are no codes. Help!!

 

3-4 clutches are gone time for a rebuild. Sent it to CPT

 

Yes i would agree the 3-4 clutch set is gone, You will need to rebuild or replace the trans

 

Yup...3-4 clutches. Thanks, Pyro. how do you like yours?

So the 3-4 clutchs go from "go to no" without any warning and no slippage?? I figured I would get some type of warning.

 

Not really sometimes it just happens

 

There's also a chance that the snap ring that retains the clutch pack has blown out. Did you raise line pressure in the transmission when you did your tune?
