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.
