Mechanical Components and Functions: Park: Notes

The park gear is splined to the front planetary carrier and the drive chain drive sprocket. There are lugs around the outer diameter of the park gear to allow the park pawl to hold the park gear stationary to the transaxle case which holds the final drive assembly in place and keeps the vehicle from moving.

When the manual control lever is rotated to the PARK position, the park lock works as follows:

• The Transmission Range (TR) sensor rotates the range detent plate which pushes the park pawl actuator rod towards the park pawl.
• The actuator rod pivots the park pawl into the lugs on the park gear, locking the gear stationary to the transaxle case.
