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.
