2-6 Clutch Releases

26 Pressure Control (PC) Solenoid 4 

The 26 PC solenoid 4 is commanded OFF, allowing PCS 26 clutch fluid to exhaust from the 2-6 clutch regulator valve.

2-6 Clutch Regulator Valve 

2-6 clutch regulator valve spring force moves the valve to the released position, allowing 26 clutch fluid from the 2-6 clutch to pass through the valve and enter the exhaust backfill fluid circuit. With the 2-6 clutch regulator valve in this position, drive fluid passes through the valve into the PS2 circuit. PS2 fluid is routed to the normally-closed #2 pressure switch and opens the switch.

2-6 Clutch 

2-6 clutch spring force moves the 2-6 clutch piston to release the 2-6 clutch plates and force 26 clutch fluid to exhaust from the transmission case assembly. The exhausting 26 clutch fluid pressure is routed to the 2-6 clutch regulator valve where it enters the exhaust backfill fluid circuit.
