Operation Of Each Valve
Torque converter pressure control valve : The function of this valve is to maintain a constant pressure within the torque converter.
Damper clutch control valve : Its function is to control the hydraulic pressure that acts on the Damper Clutch. Manual valve :The position of the manual valve is determined by the selector lever and applies or cuts line pressure to different valves.
Pressure control valve & Solenoid valve : The pressure control valve prevents a rapid decrease in hydraulic pressure when the clutch becomes disengaged. It also reduces the sharp increase in input shaft speed during clutch to clutch control.
Switch valve : When the OD clutch is applied, the hydraulic pressure is applied to the regulator valve via the switch valve. Hence, the line pressure is reduced at 3rd and 4th gear.
Fail Safe Valve-A : During fail safe mode, this valve releases the pressure in the LR Brake.
Fail Safe Valve-B : During fail safe mode, this valve cuts the pressure from the 2nd pressure control valve to 2nd brake.
