Park

When the gear selector lever is in the Park (P) position and the internal combustion engine is ON, fluid is drawn into the fluid pump and line pressure is directed to the pressure regulator valve.

Fluid Pressure Directed in Preparation for a Shift

Variable Low and 1-2 Reverse Clutch Regulator Valve

Line or auxiliary line fluid is routed through orifice #25 to the variable low and 1-2 reverse clutch regulator valve in preparation for a shift.

Variable Hi and 2-3-4 Clutch Regulator Valve

Line or auxiliary line fluid is routed through orifice #23 to the variable hi and 2-3-4 clutch regulator valve in preparation for a shift.

1-3 Reverse Clutch Regulator Valve

Line or auxiliary line fluid is routed through orifice #24 to the 1-3 reverse clutch regulator valve in preparation for a shift.

Dampener Bypass Clutch Valve

Line or auxiliary line fluid is routed through orifice #29 to the dampener bypass clutch valve in preparation for an apply of the torque dampener clutch.

Dampener Clutch Charge

Line or auxiliary line fluid is routed through orifices #42 and #43 into the dampener clutch charge circuit. Dampener clutch charge fluid fills the torque dampener clutch assembly in preparation for an apply of the torque dampener clutch.

Shift Solenoid 2

The shift solenoid 2 is energized, allowing actuator feed limit fluid to enter the solenoid 2 signal fluid circuit. Solenoid 2 signal fluid is routed to the shift solenoid valve - mode A. Solenoid 2 signal fluid is also routed to the 1-3 reverse clutch regulator valve, and to the variable hi and 2-3-4 clutch regulator valve where it enters the PS3 fluid circuit.

Shift Solenoid Valve - Mode A

Solenoid 2 signal fluid moves the shift solenoid valve - mode A, against spring force, to the applied position, in preparation for a shift.
