Pressure Control Solenoid "A" Electrical (Shift Solenoid Valve SL1) (P0748)
DESCRIPTION
Changing from 1st to 6th is performed by the ECM turning shift solenoid valves
SL1, SL2, SL3 and SL4 on and off. If an open or short circuit occurs in any of the
shift solenoid valves, the ECM controls the remaining normal shift solenoid valves
to allow the vehicle to be operated ...
