Description

The parking brake mechanism locks the transmission by engaging the parking brake pawl into the parking gear which is

splined to the countershaft.

Shifting to position causes the parking brake pawl roller (installed at the end of the parking brake shift arm) to press the

parking brake pawl onto the parking gear. Even if the end of the parking brake pawl rides on top of the parking gear teeth,

slight movement of the countershaft will cause the parking brake pawl and the parking gear to mesh with each other com-

pletely, because the parking brake shift arm receives tension from the parking brake shift arm spring. The parking brake

pawl receives the tension (which acts to separate the parking brake pawl from the parking gear) from the parking pawl

spring.
