The transmission selector assembly is located in a central position in the floor console. The assembly is attached to a molding in the floor console with four screws.
A park switch is located to the right of the lever and is operated when the lever is moved to the 'P' Park position. The lever is located in a slot in a rotary disc. The disc rotates with movement of the lever in the forward or back directions. The disk movement is detected by Hall sensors located on the selector PCB which correspond with the different selector positions.
Movement of the selector lever is passed to the transmission Mechatronic valve block via a lever located on the side of the transmission casing. The lever, in turn, moves a manually operated selector valve within the transmission valve block.
An interlock solenoid is located in the selector lever assembly. When energized, the solenoid engages an interlock lever preventing the selector lever from being moved. When the foot brake is applied, a signal from the brake switch de-energizes the solenoid allowing the selector lever to be moved from the 'P' or 'N' position. This prevents the selector from being moved to the 'D' or 'R' position unintentionally and the application of the brakes also prevents the vehicle 'creeping' when the gear is engaged.
If electrical power to the selector lever is lost, the selector lever will be locked in the 'N' or 'P' position by the shift interlock solenoid if moved from the 'D' position. The selector lever will remain locked until electrical power to the selector lever is restored. There is no emergency interlock solenoid release mechanism on the selector lever.
Selections made using the selector lever are passed to the TCM in high speed Controller Area Network (CAN) bus messages. The park switch is hardwired to the instrument cluster and the Central Junction Box (CJB).
