TORQUE CONVERTER CLUTCH SOLENOID VALVEThe 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 control 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).
