I bought a 2001 Grand Prix transmission with the overdrive out. I bought a used tranny for it. When I took the transmission out I noticed the main plug was different on the new one. Mine has a orange main plug and the one I bought has a green one and they have different pin configuration in it. Will it work? It also has a different module on the shift linkage, mine has two plugin's and the one I bought has one. Any ideas? Thanks for your help
