I can hear what is kind of a chiping mixed with grinding noise inside the cab. It only happens when truck has been in reverse. Sometimes when I leave my foot on the brake and move the tranny to park, it will remain. Sometimes I think it's an exhaust leak and other times it sounds like a bearing grinding. It is only audible inside the cab and it sounds like it is right on the other side of the firewall. Sometimes it happens as soon as I put it in reverse, other times as soon as I move, and sometimes I have to hold the brake in and press the gas. Other times it won't happen at all.

Oil pressure is good although it is due a change. Tranny temp has been low since I put in the new fluid. Sometimes it will happen when I hit a bump.

Well, the stealer found the issue...they think. Broken motor mount is allowing the motor to shift to much and believe it is causing the motor to ground out.
