TORQUE CONVERTER CLUTCH SOLENOID VALVE
TORQUE CONVERTER CLUTCH SOLENOID VALVE
PFP:31940
DescriptionECS007S8
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 position sensors. Lock-up piston operation will
then be controlled.
Lock-up operation, however, is prohibited when A/T fluid tempera-
ture is too low.
When the accelerator pedal is depressed (less than 2/8) 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.
