You would have to call the dealer or an AAMCO or transmission shop, even a slight difference or gear ratio difference, a sensor in a different location is going to cause havoc so make absolutely certain it is a different fit. Ran into a Camry with a check engine light on, customer neglected to say the transmission was replaced.
