LexusLooker Posted March 23, 2007 Share Posted March 23, 2007 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. Quote Link to comment Share on other sites More sharing options...
sheab Posted March 23, 2007 Author Share Posted March 23, 2007 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?
