Can a transmission from a 98 grand prix se 4T65E, be installed into a 98 grand prix GTP supercharged. I believe the GTP has a 4T65E HD in it. I am having trouble locating a 4T65E HD.

Thanks!
 


yes it can but you will have to get your pcm tuned for the different gear ratio. Or you can put your HD differential in the non hd tranny if the hd dif is still good
