The solenoid valve is mounted in the transmission valve housing.
The valve controls the pressure used for the torque converter clutch. The pressure is modulated so that full, partial or no engagement is achieved.
The control module activates the valve by pulsing it with B+ (300 Hz PWM). The valve is powered from control module pin 9 in the connector that makes contact directly with the transmission on the bottom of the control module. The valve is grounded from pin 4. The current varies between 0-1000 mA. The solenoid is normally closed and the hydraulic pressure rises as the current increases.
