Grinding gear
 

I got into my car today and backed out of my driveway. The car sounded like i was dragging a stick underneath the car. I put the car in drive and take off. Everything is fine.

I get to the stop sign and take my foot off the gas and my car slows on its own until I heard the grinding again. I don't know why the grinding is occurring. I made sure there was nothing under my car or in the wheels.

The longer i drive, the better it got. I actually pulled up to the dealer and the sound was almost non existent.

Anyone with a 7AT know what is going on? Its my DD & dealer said they would need to keep it for awhile to take a look at it.

Someone save me the trouble?

Thanks

brake wear indicator?

It really just sounds like its coming from the engine.. Not the brakes. But no service lights/indicators

Also, I gunned it after I was hearing the sound on braking- & sure enough when the rev hit a certain RPM it made the sound again. As if there's nails on a chalkboard

heat shield?

My heat shield?

exhaust heat shield. not sure... just trying to eliminate the basic sources of rattles first.

Its not rattle... Picture you are driving and have a large piece of tree branch dragging under the body of the car. But when you go fast you cant hear it and when you go slow it drags.

I do appreciate your help though
