Problems with 2011 Ford Fusion POWER TRAIN

Transmission "flares" (rpms jump) when upshifts occur, sometimes several hundred rpms between lower and next higher gear. this happens on irregular basis, but mostly seems to happen when car is cold. *tr

I bought a 2011 ford fusion on nov. 26, 2010. the day i brought it home, the problems started. it bangs so hard into reverse that it feels like someone ran into the car with a bulldozer. it has dead spots in the acceleration, and often goes above 5000 rpm when shifting just going down a normal flat highway. the problems have gotten worse and more frequent and are completely random. it happens with a warm engine, cold engine, in rain, snow, sun, and even after being driven for 4 hours straight. i now have over 6000miles on the car and the dealership has done nothing because ford won't authorize anything because the car is not "putting out any codes." they say they have never heard of such problems, but online forums have hundreds of the same complaints with 2010 fusions. my fear is that the acceleration will fail when i am on the expressway or in heavy traffic or that my transmission will just fall out completely. this is my first new car, and i can't afford to get another one or a long court battle. help! it's not just an inconvenience, it's unsafe. *tr
