PARKING LOCK CONSTRUCTION [5R55S]
id0513c1321300
• The parking gear is connected to the output shaft. The parking gear has lugs on its outer surface to allow the operation of the parking lock.
• The parking lock prevents the vehicle wheels from rotating by allowing the transmission case to hold the output shaft stationary through the parking gear. When the parking pawl engages the parking gear, it holds the gear stationary.
• When the manual control lever is rotated to the P position, the parking lock works as follows:
-
― The inner manual control valve detent lever (connected to the manual control shaft) rotates, pushing a spring-loaded actuator rod.
― The actuator rod pivots the parking pawl into alignment between the lugs of the parking gear.
― The parking pawl (connected to the transmission case) holds the parking gear.
