Power Flow - Park And Neutral - SSANGYONG 1999 Musso Service Manual

5A-48 AUTOMATIC TRANSMISSION

POWER FLOW - PARK AND NEUTRAL

In Park and Neutral, there is no drive to the planetary gear set. The rear band is applied to eliminate 'clunk' on
engagement of the reverse gear, and to improve the low range engagement for 4WD applications. No other clutches
or bands are applied.
In Park the transmission is mechanically locked by engaging a case mounted pawl with teeth on the output shaft ring
gear.
Control
To maintain this arrangement in the steady state solenoids and valves are activated as follows:
Solenoids S1 and S2 are switched off.
Line (pump) pressure is applied to the primary regulator valve (PRV) and to the solenoid supply valve.
The converter, oil cooler, and lubrication circuits are charged from the primary regulator valve.
The line 500 circuit is charged by the solenoid supply valve.
The S5 circuit is charged by the variable pressure solenoid (S5).
Line pressure is prevented from entering the drive circuit by the manual valve.
The B1 circuit and all clutch circuits are open to exhaust.
Refer to figure 5.1 and table 5.2.
