SOWC Servo Piston Releases

1 Reverse & 6-7-8-9 Solenoid 

The 1 reverse & 6-7-8-9 solenoid energizes applying pressure against the 1 reverse & 6-7-8-9 regulator valve spring force. This blocks LINE fluid from entering the 1 REV/6789 FEED fluid circuit. 1 REV/6789 FEED fluid is routed to the EXHAUST BACFILL fluid circuit and thru orifice #20 into the EXHAUST fluid circuit.

SOWC Servo Piston 

The SOWC servo piston is released. 1 REVERSE APPLY fluid is exhausted thru orifice #49 into the 1 REVERSE FD fluid circuit and directed thru the clutch select valve into the EXHAUST BACKFILL fluid circuit.
