P0744 A/T TCC S/V FUNCTION (LOCK -UP)
P0744 A/T TCC S/V FUNCTION (LOCK -UP)
Description
INFOID:0000000000957050
This malfunction is detected when the A/T does not shift into 5th gear position or the torque converter clutch
does not lock-up as instructed by the TCM. This is not only caused by electrical malfunction (circuits open or
shorted) but also by mechanical malfunction such as control valve sticking, improper solenoid valve operation,
etc.
