The shift by wire system uses a push button GSM which interfaces with the PCM to select gear positions.
The shift by wire system also includes a brake shift interlock that will not allow the transmission to shift out of P unless the brake pedal is applied.
The steering wheel has SelectShift® switches mounted to it that allow the driver to manually shift the transmission when D is selected on the GSM .
