I know he has the 4t60e, I'm talking about my buddy's car. its a 97 GTP which means he would have a 4t65 correct? anyone know the weight of the transmission?

 

[Bio248]

yes, the GTP came with the 4t65e-hd. its heavy.

 

[Lionel]

i hope to god that you guys got someone who is able to tune that car handy because that 4t60e is NOT going to like boost at all. it might not even shift until you let off the throttle.

Bio what cause the car to not shift until you let off. My car is doing that now after the top swap.. I throw a code p0121 for the TCS and then bam wont shift normal at all.

yours isnt the same issue i was talking about considering you dont have a vacuum controlled transmission. you have a 4t65e and i guarantee it's something in the tune that's doing that.
