3-5-Reverse Clutch Releases
3-5 R Pressure Control (PC) Solenoid
The 3-5 R PC solenoid is commanded OFF allowing PCS 3-5 reverse clutch fluid from the 3-5-reverse clutch regulator valve to exhaust.
3-5-Reverse Clutch Regulator Valve
PCS 3-5 reverse clutch fluid exhausts, allowing 3-5-reverse clutch regulator valve spring force to move the 3-5-reverse clutch regulator valve to the released position. This allows exhausting 3-5 reverse clutch fluid pressure to pass into the exhaust backfill circuit in order to assist the 3-5-reverse clutch piston spring to quickly release the 3-5-reverse clutch.
3-5-Reverse Clutch
3-5-reverse clutch spring force, assisted by exhaust backfill pressure, moves the 3-5-reverse clutch piston to release the 3-5-reverse clutch plates and force 3-5 reverse clutch fluid to exhaust from the 3-5-reverse and 4-5-6 clutch housing assembly. The exhausting 3-5 reverse clutch fluid pressure is routed to the 3-5-reverse clutch regulator valve where it enters the exhaust backfill feed circuit.
