Not likely. Remember its electronically controlled so everything will be different with a different transmission. What's the problem with the transmission that's in it now?

Nothing wrong with it. Works good. Might need a transmission mount though. Was just asking cause if there's a 5 gear automatic I'd rather have that.

Could I bolt on a GT or GTP supercharger on my 3.8 non supercharge ?

No, the internals of the engine are different. Plus you'll need the two stage fuel pump and a bunch of wiring and electronics will need to be changed. It's really not worth it. If you want a GTP buy a GTP. So if the transmission in your car is working fine why are you not happy with it.?

Hey Munron look I have an 06 GTP and I'm about to work on it improving it a little bit I would say so I was reading the conversation above and I just figured I would go ahead and put my two cents in and see what you say but personally I really don't like the transmission that's in my GTP to me it just don't seem like it does the engine Justice I'm not sure maybe my transmission is just old and needs to be rebuilt I don't have a whole lot of experience with these Pontiac Grand Prix or the 3800 or the transmission although I do have a little bit of experience with them now and I like what I've seen so far about but like I said if there was something I would want to improve it would be my transmission if there was a way and you're saying there is no transmission that can mount up to my 3800 and my other six grand prix without doing a bunch of remodeling if you get this just let me know thanks bro
