TORQUE CONVERTER CLUTCH SOLENOID VALVE CIRCUIT CHECK
The torque converter clutch solenoid valve is activated, with the gear in D4, by the A/T control unit in response to signals sent from the vehicle speed and throttle position sensors. Lock-up piston operation will then be controlled.
Lock-up operation, however, is prohibited when Automatic Transmission Fluid (ATF) temperature is too low.
