I own a 97 GT that is mechanically in good shape, but the body has seen better days. I came across a GTP with a good shell, no rust, lower miles, ect. Now I am assume something mechanically went bad in the GTP. I am still emailing the guy with the GTP and I don't have all the info on that car yet. Back to my point. I want to take my engine and trans from my GT and stick it into this GTP. First off you might be thinking "But the trans is the weaker 4T60" but I had that trans complete rebuilt a few years back and stands at 40,000 miles. The engine is still rock solid. Also the suspension in the GT is only a few months old. So that would be swapped over too.
But the body is damaged on the GT. After sideswiping a car, backing into my dad's 2500 chevy (story behind this one), and due to snow sliding into a ditch and also smacking into a tree and a fence yeah this body need very costly body work. Not include the rusted rockers, the cancer spot near the gas door, and all the fenders and bumpers being in sad shape. This GTP has a very mint looking shell. I would rate it at a 9.3 out of 10.
But I am curious to see if the 4T65 trans in the GTP is any good. I'll find out, but if I were to take my L36 engine and attach it to the 4T65 would I keep my GT ECU or GTP ECU or go pull a ECU from a 98 GT? I just don't want to do any wire cutting, adding, ect. I know the 97 GTP trans was the non HD that ended up in the 98 and above GTs. I just want to make sure everything is compatible and that codes will go off when they really need too.
Reason why I am not going for the performance route is because I want to give this my to fiance so she can have a rock solid car for work and school. She has a p.o.s. 94 integra with the a/c line ripped out with 200,000 miles. And if she gets into a crash of any sort I know the Grand Prix can take a beating and keep going or at least keep her safe.
I appreciate any help/advice.
