Wrangler 2WD V6-3.8L (2008)
The main responsibility of the converter clutch switch valve (10) is to control hydraulic pressure applied to the front (off) side of the converter clutch
piston. Line pressure from the regulator valve (5) is fed to the torque converter regulator valve (8). The pressure is then directed to the converter clutch
switch valve (10) 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 (5) controls the back (on) side of the torque converter clutch (1). When the controller energizes or modulates the
LR/CC solenoid to apply the converter clutch piston, both the converter clutch control valve (5) 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 blocked. The switch valve alienates the possibility of a sticking ball check, thus providing consistent application of the
low/reverse clutch under these operating conditions.
