(1) Answer
P0748 indicates that the control unit has detected and electrical problem (open or short) in the shift solenoid "A" circuit. This could be caused by a failed shift solenoid "A" or a problem in the wiring between the solenoid and the control unit.
Take the car to a transmission shop or a Caddy specialist for help.
