SOWC Servo Piston Applies

Reverse & 6-7-8-9 Solenoid 

The 1 reverse & 6-7-8-9 solenoid de-energizes releasing pressure against the 1 reverse & 6-7-8-9 regulator valve spring force. This allows LINE fluid to enter the 1 REV/6789 FEED fluid circuit. 1 REV/6789 FEED fluid is routed thru orifice #40 to the latch valve and to the clutch select valve.

Clutch Select Valve 

1 REV/6789 FEED fluid is routed thru the clutch select valve into the 1 REVERSE FEED fluid circuit. 1 REVERSE FEED fluid seats ball check valve #10 and is forced thru orifice #49 into the 1 REVERSE APPLY fluid circuit. 1 REVERSE APPLY fluid is directed to the SOWC servo piston.

SOWC Servo Piston 

1 REVERSE APPLY fluid is directed into the SOWC servo piston applying pressure against piston spring force.
