Thread: Transmission Slipping on 97GTP. Interchange?

I have a 97 GTP with over 200k on it, The transmission is starting to slip on it, I want to get a used transmission and put it in, My question is what do I need to look for for a 4t65e-hd? does it have to be from a grand prix or will that trans out of another model work? I found a couple for sale but they show having the 3.29 ratio, whats the ratio on the GTPs?

From my understanding is the 1997 SE and GT models still used the 4t60e vacuum controlled trans and the 97 GTP models had the 4t65E along with all 98-03 3800. am I correct?

Basically I want to know what my options are for a used tranny.

Ok, I found a locak guy that has a trans out of a GT with a ZZP shift hit and a HD conversion kit in it with 50 on it, what will I need to do to make it work having the 3.29s?

so im assuming that would involve sending the pcm to zzp, basically add 125 to the bill
