The manual valve is operated by the mechanical shift linkage. Its primary responsibility is to send line pressure
to the appropriate hydraulic circuits and solenoids. The valve has three operating ranges or positions.
CONVERTER CLUTCH SWITCH VALVE
The main responsibility of the converter clutch switch valve is to control hydraulic pressure applied to the front
(off) side of the converter clutch piston. Line pressure from the regulator valve is fed to the torque converter
regulator valve, where it passes through the valve, and is slightly regulated. The pressure is then directed to the
converter clutch switch valve and to the front side of the converter clutch piston. This pressure pushes the piston
back and disengages the converter clutch.
CONVERTER CLUTCH CONTROL VALVE
The converter clutch control valve controls the back (on) side of the torque converter clutch. When the
PCM/TCM energizes or modulates the LR/CC solenoid to apply the converter clutch piston, both the converter
clutch control valve and the converter control valve move, allowing pressure to be applied to the back side of
the clutch.
T/C REGULATOR VALVE
The torque converter regulator valve slightly regulates the flow of fluid to the torque converter.
LOW/REVERSE SWITCH VALVE
The low/reverse clutch is applied from different sources, depending on whether low (1st) gear or reverse is
selected. The low/reverse switch valve alternates positions depending on from which direction fluid pressure is
applied. By design, when the valve is shifted by fluid pressure from one channel, the opposing channel is
locked. The switch valve alienates the possibility of a sticking ball check, thus providing consistent application
of the low/reverse clutch under all operating conditions.
