Soft shift when warm

I am STILL having transmission problems.

I have the transgo kit with the .500 boost valve and the 'vette servo.

When the car is colt it will chirp the tires shifting into second. When the transmission warms, the shift takes forever and is very very soft.


Any suggestions?

Re: Soft shift when warm

I would be suspect of internal leakage or sticking pump slide or regulator when warm

I forgot to mention that only the 1-2 shift is affected, if that matters.


I will look into your suggestions... I also suspect some sort of leakage.

Thank you very much for your reply, I really could use the help lol.

Re: Soft shift when warm

If the 1-2 shift is the only on affected I would closely inspect the 1-2 servo rings first

I just put in a corvette servo. I remember installing a 2nd apply piston, is that what are you referring too?
