Torque Converter Clutch Solenoid: Description and Operation






The Torque Converter Clutch Solenoid valve (TCC Sol. valve) is a three-port assembly which uses negative (-) duty cycle, pulse-width modulation (PWM) to control the rate of TCC apply and release. The solenoid's ability to ramp apply and release pressures results in a smoother apply and release of the TCC in all conditions.

The TCC sol valve is a normally closed valve, mounted to the upper valve body and used to control the position of the TCC apply valve.
TCC solenoid resistance should be 10-11 ohms when measured at 20° C (68° F). Resistance should be 13-15 ohms when measured at 100° C (212° F).
