Parking Lock Mechanism; Function Of Parking (P) Lock - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

Function of parking (P) lock

The selector lever position "P" is locked whenever the R/P
locking solenoid is not actuated by selector lever control unit.
The prerequisites for this are as follows:
* No voltage supply to the selector lever control unit (Ignition
switch is not positioned to "ON")
* Brake pedal not depressed
Under these conditions, the locking lever (8) is in the locking
position. The tab on lock lever (9) locks the locking disc (1). It
is not possible to shift the selector lever out of selector lever
position "P".

Parking Lock Mechanism

Location and function
The parking lock gear (6) is located on the output shaft in the
rear section of the transmission housing. In selector lever po-
sition "P", the cone (3) slides between the parking lock pawl
(4) and the guide sleeve (5). The parking lock pawl (4) is there-
fore pushed against the parking lock gear (6). If the tooth of
the parking lock pawl (4) does not engage in a tooth space
when the vehicle is stationary, but rather touches a tooth of
the parking lock gear (6), the cone (3) is pre-tensioned by the
spring (2) and positioned ready for operation. If the parking
lock gear (6) continues to turn, the parking lock pawl (4) en-
gages in the next tooth space. To prevent damage due to
misuse, the widths of the tooth spaces are designed such
that the parking lock pawl (4) can only engage when the ve-
hicle is stationary or moving very slowly. If the vehicle rolls
faster, the shape of the teeth prevents the parking lock pawl
(4) from engaging.
