I was told that there were 4 different transmissions in grand prix's.. 2 in the gt's and se's and 2 in the gtp's. And that i have to find one with the same id code as mine or it wouldnt work right. Well i cant see the id tag on my trans and dont have a life or jack at my house. Im considering trailering it to the dealership i work at to put it on the lift ony day off. Any help is greatly appreciated.
