Code P0741 Acura Description

The power transfer capacity of the torque converter clutch is controlled by the balance of transmission fluid supply to and discharge from the torque converter. When hydraulic pressure is applied internally, the torque converter clutch turns ON, and when hydraulic pressure is applied from the back pressure side, the torque converter clutch turns OFF. As the hydraulic pressure from the internal pressure side increases, the power transfer capacity of the torque converter clutch increases. The direction of the hydraulic pressure supply is switched by shift solenoid valve B and the LC shift valve. Transmission fluid is supplied from the internal pressure side to shift solenoid valve B when the signal from the Powertrain Control Module (PCM) is ON (12 V), and transmission fluid is supplied from the back pressure side when it is OFF (0 V). The balance of internal pressure and back pressure is controlled by the CVT lock-up clutch control solenoid valve and the LC control valve. The CVT lock-up clutch control solenoid valve maximizes the power transfer capacity of the torque converter clutch when the signal from the PCM is ON (1 A), and it minimizes the power transfer capacity of the torque converter clutch when the signal from the PCM is OFF (0 A). If the ratio of engine speed and input shaft speed is not about 1:1 while the PCM is issuing the command to turn shift solenoid valve B and the CVT lock-up clutch control solenoid valve ON, the PCM detects a faulty lock-up control system and stores a Diagnostic Trouble Code (DTC).
