Ok I got a new used transmission for my 04 Grand Prix. Ok now I the guy installed it but the high pressure transmission line is leaking. So I went to advance auto parts. The guy told me its about 20 bucks. Turns out it was 60. So I got it and he told me the one line I got doesn't fit on the transmission. He thinks the transmission I got is for a newer Grand Prix because he said he saw something that said 2008 on the tranny. So should I return to the store and tell them I need an 08 tranny line hose? Or what ?
