DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionNCS0003I

Torque converter clutch solenoid valve is activated, with the gear in D4 , D5 , M2 , M3 , M4 and M5 by the
TCM in response to signals sent from the vehicle speed sensor and accelerator pedal position sensor
(throttle position sensor). Torque converter clutch piston operation will then be controlled.

Lock-up operation, however, is prohibited when A/T fluid temperature is too low.

When the accelerator pedal is depressed (less than 1.0/8) 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.
