I've had the clunking from 1-2 and 2-3 for a few months now, and after Ford had it for a week they told me after extensive testing "It's normal, and we even have another doing the same thing". I told them all that means is they have TWO bad cars, and that this isn't normal for a new car. Well, last week the service guy told me Ford is indeed working up a TSB that should be issued in a month or so to address the issue. Fingers crossed!
