General Information

P0755 Shift Control Solenoid Valve \'B\'(Under Drive Clutch Solenoid)

General Information

Component Location





General Description

The Automatic Transmission changes the gear position of the transmission utilizing a combination of Clutches and Brakes, which are controlled by solenoid valves. This Automatic Transmission consists of a: LR (Low and Reverse Brake), 2-4 (2-4 Brake), UD (Under Drive Clutch), OD (Over Drive Clutch), REV (Reverse Clutch).

DTC Description

The PCM/TCM checks the Under Drive Clutch Control Signal by monitoring the feedback signal from the solenoid valve drive circuit. If an unexpected signal is monitored (for example, high voltage is detected when low voltage is expected, or low voltage is detected when high voltage is expected), the PCM/TCM judges that OVER DRIVE CLUTCH drive control solenoid circuit is malfunctioning and sets this code.
