Vehicle Shudder problems of the 2008 Ford Escape

My vehicle will be in motion while driving and suddenly have a shifting problem. The vehicle will shake and stutter and looses power no matter how much you press your foot on the gas peddle. My engine light flashed on and off a couple times and then once my vehicle shifted, it would idle rough and act like it was going to die when I would stop at a light. This has been happening for several days now at different speeds on residential streets and the highway. The engine light has not come on since. I took it to have the error code read from the engine light coming on but it was only a generic code. One of the codes was for an airbag sensor. I do not know what is wrong with it.

Tl- the contact owns a 2008 Ford Escape. The contact stated that when stopped at a traffic light, the vehicle began shuddering when the accelorator pedal was depressed. The contact stated that the vehicle had also independently reversed. The failure caused the contact to shift the gear into park in order to stop the vehicle. The failure recurred multiple times. The vehicle had not been taken to a mechanic for a diagnosis. The manufacturer had not been notified of the failure and the approximate failure mileage was 97,000. Gb.

Vehicle wrench light came on the dash in the morning going to work. On the way home I was stopping by local auto parts store to have code tested. The auto parts tech said that there were no codes popping up. As I left and pulled away from the store the transmission jumped in rpms before it lurched into the 2nd automatic gear causing the vehicle to shudder. Every time I accelerated from a stop to higher speeds the rpms would jump up to 3-4 thousand before it would jump into the next gear. Took the vehicle to a dealer garage. They said it was giving them codes related to TSB 12-4-8. The estimate for the repair is $2200. Ford has issued this as a TSB knowing that it is an issue. They should take care of the repair.
