1-2-3-4-5-6 Clutch Releases

1-2-3-4-5-6 Solenoid 

The 1-2-3-4-5-6 solenoid energizes applying pressure against the 1-2-3-4-5-6 regulator valve spring force. This blocks DRIVE fluid from entering the 123456 CLUTCH REGULATOR fluid circuit. 123456 CLUTCH REGULATOR fluid is exhausted thru orifice #15 and #11 into the EX BACKFILL fluid circuit and thru orifice #8 into the EXHAUST fluid circuit.
