DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000001327209
 The torque converter clutch solenoid va lve is activated, with the gear in D5, M3, M4 and M5 by the TCM in
response to signals sent from the vehicle speed sensor and accelerator pedal position sensor (throttle posi-
tion 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.
