GF27.60-P-2010AHI Park pawl component description
- TRANSMISSION 722.930

Component Identification:

Location
The park pawl gear and park pawl mechanism are located in the rear part of the transmission housing.

Task
Secures the vehicle mechanically, in addition to the parking brake, in order to prevent it from rolling.

Function
In selector switch position "P" the cone slides between the park detent and the pilot bushing. As a result the park detent is pressed against the park pawl gear.

If the tooth of the park detent does not engage in a tooth space when the vehicle is stationary, but rather touches a tooth of the park pawl gear, the cone is pre-tensioned by the spring and positioned ready for operation. When the park pawl gear turns further, the park detent engages in the next tooth gap.

To prevent damage due to incorrect operation, the intervals between the tooth gaps are such that the park detent can only engage when the vehicle is stationary or crawling at low speed. If the vehicle moves faster, the park detent is deflected by the oblique surfaces of the teeth and cannot engage.
