I am truly sorry for the hassle you are experiencing with your shifting concerns. I understand that it is very frustrating to have to worry about your brand new car shaking all over inside, especially to the point you are unable to even have a cup of coffee. It is positive news that the dealer is actively working to diagnose your issue. I would like to assist in resolving this for you. Please PM me your VIN, contact info, mileage, and dealer so I can try to help.
