The jerk is very quick almost like the motor is missing. As soon as you apply a little throttle it goes away. I haven't completely ruled out the motor but it feels as if it is generated from the middle of the car. Any others have this happen? Any diagnosis? TIA.

Had the same issue on my 05 4.4 at around 58-60K miles. Had issues recreating the problem with the tech, but they did note it. It got worse and finally the tech was able to feel it. Dealer replaced tranny under good will. Phew that would have cost a lot out of warranty.
