Yep...sounds like you took your car to my dealer too....LOL
I was driving home tonight with wife and kid in car. I pulled off from a stop and decided to pull off quicker than usual, instead of easing into the pull off. My wife turned to me and asked why the car shuddered...I handed her a 2 page piece of paper...LOL.
While driving to the next light I turned off the traction control. I repeated the same pull off...no shudder.
This is definitely related and part of the problem.
Also, I was told that I would be receiving a followup call from Ford Customer Service today.
I am still waiting.....It is now 9pm...
I have been driving with the Traction Control off for a week now to test this and it diminishes the shudder to almost nothing. When I turn it on, the problems begin to creep back.
