Hey is it possible to put a 4T65-e transmission in a 97 GP GT. The car comes with the 4T60-e like the Buick Riviera, LeSabre, and alot of other GM cars with the 3800 platform in 1997. I know that this version of the 4T60 is electronically controlled as opposed to its vacuum controlled predecessor. I would like to upgrade my tranny to 4t65-HD but my car doesnt even have a 65 trans.
Thanks
