DTC P0755 SHIFT CONTROL SOLENOID VALVE B CIRCUIT MALFUNCTION

COMPONENT LOCATION

GENERAL DESCRIPTION

The Automatic transmission changes the gear position of the transmission by utilizing a combination of clutches
and brakes, which are controlled by solenoid valves. This automatic transmission consists of a: LR (Low and
Reverse Brake), 2ND (2nd Brake), UD (Under Drive Clutch), OD (Over Drive Clutch), REV (Reverse Clutch),
and a RED (Reduction Brake, only for 5 speed transmissions). The UD Clutch is engaged in the 1st gear, 2nd
gear and 3rd gear positions.

DTC DESCRIPTION

The 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 TCM judges that Under
Drive control solenoid circuit is malfunctioning and sets this code.
