Abstract
A switch valve for a torque converter clutch switch valve body having a bore with line-in and apply ports. The switch valve has a plunger with a bore defined therein. The plunger is configured for moving in the switch valve body bore between first and second positions, whereby fluid communication with the line-in port is prevented and permitted in the first and second positions, respectively. A first spring biases the plunger towards the first position. A limit valve is positioned in the bore of the plunger and has a piston configured for moving in the plunger bore between first and second positions, whereby fluid communication with the apply port is prevented and permitted in the first and second positions, respectively. A second spring biases the limit valve towards the second position. Overpressure from the line-in port moves the piston towards the first position to prevent overpressure to the apply port.
