Torque Converter Clutch Solenoid Valve
DESCRIPTION
The torque converter clutch solenoid valve is activated, with the
gear in D
4, by the TCM in response to signals sent from the vehicle
speed and throttle (accelerator) position sensors. Torque converter
clutch piston operation will then be controlled.
Lock-up operation, however, is prohibited when A/T fluid tempera-
ture is too low.
