3-5 Reverse Clutch Applies

3-5-R Pressure Control Solenoid 2 

The 3-5-R pressure control Solenoid 2 is commanded ON, allowing actuator feed fluid to enter the PCS 3-5-Reverse clutch fluid circuit. PCS 3-5-Reverse clutch fluid is routed through orifice #36 and then to the 3-5 reverse clutch regulator valve. PCS 3-5-Reverse clutch fluid is also routed through orifice #37 and then to the 3-5 reverse clutch boost valve.

3-5 Reverse Clutch Boost Valve 

PCS 3-5-Reverse clutch fluid pressure acts on a differential area moving the PCS 3-5 reverse clutch boost valve against the 3-5 reverse clutch boost valve spring. The 3-5-Reverse clutch fluid passes through the valve and enters the 3-5-Reverse clutch feedback circuit. As PCS 3-5-Reverse clutch fluid pressure is increased to a given value, the 3-5 reverse clutch boost valve opens the 3-5 Reverse Clutch feedback circuit to exhaust. This results in the 3-5 reverse clutch regulator valve moving to the full feed position sending full 3-5-Reverse clutch feed pressure (full line pressure) to the clutch.

3-5 Reverse Clutch Regulator Valve 

PCS 3-5-Reverse clutch fluid moves the 3-5 reverse clutch regulator valve against 3-5 reverse clutch regulator valve spring force and 3-5-Reverse clutch feedback fluid. This allows 3-5-Reverse feed to pass through the valve and enter the 3-5-Reverse clutch circuit. The 3-5-Reverse clutch fluid is then routed to the 3-5 reverse clutch, the 3-5 reverse boost valve and the clutch select valve 2. When the 3-5 reverse clutch regulator valve is in this position, PS 2 fluid from the pressure Switch 2 exhausts through the valve allowing the switch to close.

Clutch Select Valve 2 

The 3-5-Reverse clutch fluid passes through the clutch select valve 2 and enters the 1-2-3-4 clutch default feed fluid circuit. The 1-2-3-4 clutch default feed fluid is then routed to the clutch select valve 3.

3-5 Reverse Clutch 

The 3-5-Reverse clutch fluid enters the 3-5 reverse/4-5-6 Clutch housing to move the piston against spring force combined with force from the compensator to apply the 3-5 reverse clutch plates.
