From what I've read the transmission in this 04comp G has different rear end gears than all other gtp's. And I've read th at only the comp G and one other thing like a Buick rendezvous are only trannys that interchange. Is that correct. I have a 97 Grand prix gt 3.8 and a 03 gtp supercharged 3.8. Won't either of these transmissions work
