97 Gtp trans swap into a 00 Monte Carlo
Anybody know if it will work or could I swap the trans harness inside to make it work an get my gear ratio upgraded to
|
You don't need to change the harness, the transmission should bolt right up, you MIGHT need an L67 flexplate. But you would have to change the gear ratio in the tune of your PCM though.
|
Watch out with the 97 models. If I recall correctly, there were differences between it and the 98+ transmissions. I do know that the 98+ PCMs are different and run a common OS across all the V6 platforms. The 98+ PCMs are also more tunable, but I'm not sure how they would react with a 97 trans. The 97 GTP was a different animal that had some weird differences compared to the 98-03 GTPs.

The '97 Grand Prix had like ODB-1.5 and NO ONE to my knowledge makes a tuner for it. I have heard that people have re-wired and installed a '98+ PCM into a '97, so seeing that, I bet a '97 trans can be tuned in a 98+ car.
I believe the '97 trans on the Grand Prix is also vacuum assisted (has a vac line that connects to the throttle body). There may be a few other differences and "gotchas" in the process. |
powrtuner will work on some 96's and 97's. though the support is very limited. ive seen the bin files for 96's and 97's.
|
So I will be taking a chance with the 97 trans an another question if I install it would I be able to test it right away to make sure it works but I don't have gear ratio change yet or how does that work?
|
im wondering, why are you trying to put a 97 gtp trans into a 00 monte?
do you have the LS or the SS??? unless you have already have the trans, dont even bother with it. find one on Car-Part.com--Used Auto Parts Market |
Iam supercharged an my trans is done an the 97 I got for free
|
Jason I'd right. One of the key differences between the 97 and 98+ GTP transmissions is the 97 still runs vacuum. You will have to have a 97 year GTP throttle body in order to use it as far as I know unless you want to mod either the trans.
|
So if it doesn't have the vaccum then I should be good to use it?
