4. Is resistance within specification?
YES
Go to step 2.
NO
Replace "PRESS CONTROL SOL VALVE (VFS)" as necessary and go to
"VERIFICATION OF VEHICLE REPAIR" procedure.
2. CHECK PCM/TCM
1. Connect scan tool to data link connector (DLC).
2. Ignition "ON" & Engine "OFF".
3. Select A/T Solenoid valve Actuator test and Operate Actuator test.
4. Can you hear operating sound for "PRESS CONTROL SOL VALVE (VFS)" Actuator testing
function?
YES
Go to "VERIFICATION OF VEHICLE REPAIR" procedure.
NO
Replace PCM/TCM as necessary and go to "VERIFICATION OF VEHICLE REPAIR"
procedure.
ACTUATOR TEST CONDITION

DTC P0750 SHIFT CONTROL SOLENOID VALVE A 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 LR Brake is engaged in the 1st gear and
reverse gear positions.
DTC DESCRIPTION
The TCM checks the Low and Reverse 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 the Low
and Reverse control solenoid circuit is malfunctioning and sets this code.
