Grinding Sound From Cadillac CTS.


Topic starter

Hey Scotty, my mother drives a 2006 Cadillac CTS with 149,000 miles. When she puts the car in reverse, while backing up there is a loud grinding sound coming from the car. It’s beginning to happen more as time goes on and the local mechanics can’t ever seem to find how what is wrong with the car.

I’m at a loss on what to do with this and was hoping you’d have an answer. Thanks.

Put a scan tool into your car's OBD port and see if any codes pop up, since it's grinding it's possible that reverse gear might be going out. That's what I would assume since it's a 2006 CTS with almost 150k miles. especially if it has the original transmission.
