Hello, need some help. Im installing a transmission in my 94 pontiac firebird, the problem im having is that the vin# does not match up with the engine i have in the car. The last owner changed it from the v6 to the v8 lt1. now im trying to get a rebuilt transmission from a good dealer and they keep sending me the transmission from a v6 witch dont match up. all i need is a vin# from a pontiac firebird that has a v8 lt1. i would be very greatfull. Im not sure if it is a legal issue car number vin info. I really just wanted to ask.. maybe an engine number would work im not sure.
