AUTOMATIC TRANSMISSION AND DIFF ERENTIAL
16. Parking Mechanism
The end of the parking pawl engages mechanically with
the gear groove of the parking gear. This gear is spline-
fitted to the drive pinion shaft .
When the selector lever is set to "P", the manual lever
connected to the manual shaft turns, moving the park-
ing rod backward . A cam and spring are installed on the
rear of the parking rod . The parking cam slides freely on
the parking rod . The parking rod and cam contact the
"V" groove of the actuator (secured to the transmission
case) and the back of the parking pawl . With this
arrangement, when the parking rod moves backward,
the cam moves to the back of the parking pawl and the
"V" groove of the actuator . The parking pawl turns in
the direction of the parking gear using the parking pawl
shaft as a pivot. It then engages with the parking gear
groove .
If the end of the parking pawl rides over the tooth of the
parking gear so that the parking cam does not move
midway between the pawl and actuator, the parking rod
will move to "P". This compresses the parking spring so
that the parking cam is ready to move to "P". Under this
condition, if the vehicle moves slightly, the parking gear
will rotate to engage the pawl completely .
Except for the P range, the parking pawl is tensed by the
parking pawl return spring in the direction that moves
away from the parking gear .
