Power Flow - Drive 4 Lock Up - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

Power flow - Drive 4 lock up

In Drive 4 Lock Up, transmission drive is the same as for
Drive 4 but with the application of the converter lock up
clutch to provide positive no-slip converter drive.
Control
To maintain this arrangement in the steady state sole-
noids and valves are activated as follows;
• When S7 is switched ON, S7 feed oil to the converter
clutch control valve is switched OFF and allowed to
exhaust through the S7 solenoid. This allows the valve
to move to the clutch engage position.
