GENERAL DESCRIPTION

The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the
5th gear ratio, while the transaxle is engaged in the 5th gear. For example, if the output speed is 1,000 RPM and
the 5th gear ratio is 0.868, then the input speed is 868 RPM.

DTC DESCRIPTION

This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by
the 5th gear ratio, while the transaxle is engaged in 5th gear. This malfunction is mainly caused by mechanical
troubles such as control valve sticking or solenoid valve malfunctioning rather than an electrical issue.

DTC P0741 TORQUE CONVERTER CLUTCH CIRCUIT - STUCK OFF

GENERAL DESCRIPTION

The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch (or Damper Clutch), to the
input shaft of the transmission, by applying hydraulic pressure. The main purpose of T/C clutch control is to
save fuel by decreasing the hydraulic load inside the T/C. The PCM/TCM outputs duty pulses to control the
