Can you please advise what else we need to do.

My car has 65000 miles.
My car has an automatic transmission.

Hi there. Within the transmission the shift solenoid has lost power. Check the transmission oil level and make sure it is full with the engine running. Check the wiring harness to the transmission for any damaged wires or burned pins. If the wiring harness is okay and working, then the shift solenoid A has overheated or it has shorted it out. I recommend replacing the shift solenoid in the transmission. If you need further assistance with your vehicle, then seek out a professional, such as one from YourMechanic, to help you diagnose your Check Engine Light and transmission shifting issue for an accurate repair.
