How are your engine and transmission mounts? The car is stopping, but the mounts could be shot, allowing the engine and tranny to shift (move) forward.

all 3 mounts are brand new replace em at the dealer last month ! be advice that it happen only when i break.. doesnt happen when i break lightly or when the car stop compleatly..by the way when i said jerk ..i didnt meant the car wanna run forward .. what i mean by jerk is that the gear knocb move back and forth like when i break it wanna stop but then let it go . its kinda like how you feel when u drop on a whole and come back flat surface .. umm am i confusing?
