Converter Clutch Control Valve
The CC control valve has the job of controlling the back or
“on” side of the torque converter clutch. When the TCM ener- “L)
gizes the LR/CC solenoid to engage the converter clutch piston,
the CC control valve and T/C control valves move to the left.
The oil on the front or “off” side of the converter clutch piston
is vented to the sump.
Line pressure enters the CC control valve through the manual
valve and then passes through the CC control valve and the
T/C control valve to the back (“on”) side of the converter clutch
piston. Line pressure forces the piston forward which engages
the torque converter clutch. This action effectively connects
the torque converter turbine with the impeller. Line pressure
also flows from the regulator valve, through the T/C control
valve, to the cooler and cooler bypass for improved fluid and
transaxle cooling.
Solenoid Switch Valve
The switch valve controls line pressure direction from the LR/CC
solenoid. When the valve is shifted to the right, it allows the
low/reverse (L/R) clutch to be pressurized. When it is shifted
to the left, it directs line pressure to the T/C and CC control
d
valves to operate the T/C clutch. The valve is shifted to the
right in all positions except second, third, or fourth gear. When
the transaxle upshifts to second gear, the valve moves to the
left which allows converter clutch engagement when needed.
The valve must return to the right before a downshift to first
gear can occur.
