Yes, I've been in a manual transmission car. I've driven autocross and hill climb events. First car was a Sunbeam then a manual tran Mustang 289. I've also bought many, many new cars and I've never experienced problems that caused me to take it back to the dealership this many times. I'm 59 years old and not a newbie to what smooth and rough rides feel like. I don't mind a harder than normal shift to gain power and economy; I just don't want to crack a tooth. Also remember, this is all happening at a constant 2 or 3 miles an hour. There is no acceleration involved. In fact, it is under very light pressure on the break, just like in a stop-and-go traffic situation. It feels like the trans can't make up it's mind if it wants to be in neutral of first gear and very quickly shutters between the two. And, the trans expert at the Ford dealership says it's not normal when he rode in the parking lot with me yesterday. He was actually astonished. Finally, I've done more than make a cell phone video of this. As the news director for a television station, I've had a photographer record the shuttering on a Panasonic P2 camera to document this whole episode. If I wind up having to post it online, I'll provide a link. I just want it fixed or my money back.
