I've had my Mustang for less than a month. The miserable thing has already broken. It started Friday evening. I was driving my car and came to a stop at a red light. When the signal turned green, I proceeded forward. All of a sudden the car violently shifts into another gear. I drive until I find a lot where I can stop for a moment. I let the car sit for a while then turn it on again. When put it into drive, the car shifted in to gear very violently. As I took off it was obvious that the car was not in first or second gear. When I got home I put the car into reverse and again it changed to gear violently. Then next morning I went to the Ford dealership to have them take a look. After two hours, at the dealership, I was told they believe it is a solenoid, but they would not be certain until Monday. After that they set me up with rental car. This has been bugging me all weekend. Needless to say, I absolutely hate my new Mustang. By the way, I've been nothing but gentle with this car.
