My 2007 C30 T5 with the five speed automatic has started having a problem where it will jerk when accelerating after coasting (example: slowing down for a stoplight but it turns green before you come to a complete stop). It is less noticeable if I ease into the throttle but is most noticeable if I try to accelerate moderately or fast. The car has 150,000 km and the transmission fluid was changed at 100,000. The transmission also jerks slightly when shifting (I’m not sure if this is how all automatics feel or not) and has a slight clunk when going into drive or reverse (again, not sure if this is normal for automatics). Do I have anything to worry about and has anybody else had this problem?
