weird invinsible push
i'm at 18k. every time i drive the car from start, the car after 5-10 minutes, at the stop light a fan comes on (it is audible) then a "push" occurs or a jerk. i do not know if transmission is to blame, but what is this fan sound coming on? (btw, weather is around 40F). when i mention the car pushes forward, i mean that if my foot is not glued tight on to the brake and on it hard, that car will move forward.
