3-5-Reverse Clutch Applies
3-5 R Pressure Control (PC) Solenoid
The 3-5 R PC solenoid is commanded ON, allowing actuator feed limit fluid to enter the PCS 3-5 reverse clutch fluid circuit. PCS 3-5 reverse clutch fluid is routed through orifice #2-6 to the 3-5-reverse clutch regulator valve.
3-5-Reverse Clutch Regulator Valve
PCS 3-5 reverse clutch fluid, at the 3-5-reverse clutch regulator valve, opposes 3-5-reverse clutch regulator valve spring force and 3-5 reverse clutch feedback fluid pressure to regulate 3-5 reverse clutch feed/drive 1-6 pressure into the 3-5 reverse clutch circuit. The 3-5 reverse clutch fluid is then routed through orifice #25 to the 3-5-reverse clutch assembly, through orifice #6 to the spring end of the 3-5-reverse clutch regulator valve and through orifice #33 to the #4 ball check valve.
3-5-Reverse Clutch
3-5 reverse clutch fluid enters the 3-5-reverse and 4-5-6 clutch housing assembly to move the 3-5-reverse clutch piston against spring force and exhaust backfill fluid pressure to apply the 3-5-reverse clutch plates.
#4 Ball Check Valve
3-5 reverse clutch feed fluid unseats the #4 ball check valve, allowing excess pressure to pass into the actuator feed limit circuit. This helps to control clutch apply fluid pressure and clutch apply feel.
Accumulator
PCS 3-5 reverse clutch fluid is also routed to an accumulator valve. The accumulator valve is used to dampen any pressure irregularities occurring in the PCS 3-5 reverse clutch fluid circuit. This helps to control clutch apply fluid pressure and clutch apply feel.
