TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionBCS0011O
Torque converter clutch solenoid valve is activated, with the gear in D4 , D3 and 33 , by TCM in response to
signals sent from vehicle speed and the ECM (throttle opening). Lock-up piston operation will then be con-
trolled.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
