Now this is a nes one for me. I was on a trip yesterday, and through a rough road when I hit a bump hard enough I heard grinding sound coming from underneath the center console. I sounded like a manual transmission not going into gear. If I hit hard enough on the brakes the noise seemed to go away. So what I tried was when I heard the noise to put it into neutral and the noise still persisted. I also tried keeping it in third in case it was a problem with the fourth gear, same noise kept poping out every couples of bumps.

Any ideas??
