Pressure Control Solenoid (PCS)

PURPOSE
This electrical device, controlled by the PCM, is used to control fluid line pressure.

OPERATION
The solenoid controls line pressure by controlling actuator feed limit fluid flow acting on internal spool valve and spring pressure. The solenoid is a normally closed solenoid valve that controls fluid pressure when operating on a duty cycle.

LOCATION
The solenoid is attached to the control valve body within the transmission.
