Cherokee 4WD LHD L6-4.0L VIN S (2001)
The cut-back valve (Fig. 296) helps prevent excessive pump pressure buildup in second, third and fourth gear. The valve is actuated by throttle
pressure and by line pressure from the second brake. The valve also helps regulate line pressure by controlling the amount of cut-back pressure to the
throttle valve.
SECONDARY REGULATOR VALVE
The secondary regulator valve (Fig. 297) regulates converter clutch and transmission lubrication pressure. When primary regulator valve pressure
exceeds requirements for clutch engagement or transmission lubrication, the secondary regulator valve is moved upward exposing the drain port.
Excess pressure then bleeds off as needed. As pressure drops, spring tension moves the valve downward closing the drain port.
