When coming to a stop my car shifts from 3rd to 2nd her very abruptly. It makes it feel as though I've slammed on my brakes very suddenly. It also does it when I slow my car then press the gas to accelerate sometimes. I've taken my car to the dealership over 5 times since first purchased by my mother in 2010 and the dealership always claimed to be unable to notice the sudden jerking. This jerking happens mostly on the street due to my continual stop and go, but it has also happened while getting on the freeway and during freeway traffic.
Vehicle jerks when downshifting at about 20 mph.
While decelerating, either braking or coasting, the car will lurch violently when reaching approximately 22 mph. The severity of the lurch varies but in most instances it is hard enough to snap my neck forward.
