Notes:

Please call with your VIN to order this transmission. Gearstar will program the transmission's control module with your VIN so it will be ready to use when you receive it. If the transmission is to be used with an aftermarket controller in a swap application, it will be programmed with a generic VIN that will work with these controllers.
