DescriptionNJAT0055The torque converter clutch solenoid valve is activated, with the
gear in ªD
4º, by the TCM in response to signals sent from the
vehicle speed and throttle position sensors. Lock-up piston opera-
tion 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.
