As mentioned above if the vibration goes away when the clutch is pushed in then that eliminates everything behind the clutch plate. When I had my 2012 GT I had my whining 3.73 gears replaced under warranty and ended up with a vibration. It would still vibrate when the clutch was pushed in. I re-indexed the OEM drive shaft and then swapped to an aluminum shaft and still had the issue. Dealerships could never solve it. Ended up selling the car. I hope you get yours sorted out.
