Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Selector Mechanism
Selection of the required driving mode, through the selector lever inside the vehicle, activates a selector shaft within the transmission. A push/pull type cable connects the lever in the car and the shaft on the gearbox. A cam fitted to the selector shaft is also connected to the manual valve of the control system, and selects one of its five desired positions (PRNDS/M). Moving the selector lever across the gate trips a proximity sensor.
A spring and cone operated pawl mechanically locks the secondary pulley when the selector lever is moved to the Park position. If selection of park is made at speed the pawl will rattle without engaging Park. It will not engage until the vehicle speed drops below approximately 3 mph.
Movement of the selector lever (or steering wheel buttons) in a forward direction, plus (+), changes the transmission up the gear ratios and movement in a rearward direction, minus (-), changes the transmission down the gear ratios.
