how do i tell if my car has a 4 speed or a 3 speed auto transmission? a friend of mine said the 3 speed ecu with work for a standard conversion and a 4 speed wont...not sure if hes right but i figure this would be the place to get the right info.
check ur numbers on the gear shifter if its P R N D 123 its a 4 speed and 3 speed is PR N D 12
