Pressure Regulation

Pressure Regulator Valve 

This valve regulates the pump output in response to several forces: torque signal, fluid pressure, reverse gear, orificed line pressure and spring force. Line pressure from this valve is then routed to the actuator feed limit valve, the 1-2 & 3-4 accumulator valve, the 2-3 accumulator valve, and the converter clutch regulating valve.

Actuator Feed Limit Valve 

The line pressure is limited to a maximum force as it passes through the actuator feed limit valve and enters the actuator feed circuit. Actuator feed is then routed to the pressure control solenoid valve, and into the fluid circuits of the 1-2 and the 2-3 shift solenoid valves.
