I have a 2000 grand prix GT with a N/A 3.8, the trans is bad and I am going to swap it out, my question is I already have a transmission that i know works good out of a 98 buick regal ls, would this work in the grand prix and function properly, if not what would need to be done. Also I have a grand prix GTP, whats the interchange on the transmission for GTP cars.
Thanks for you time.
