I have a 2004 C230 Kompressor Coupe with 5-speed auto transmission. When I am slowing down to stop, the brakes become very non-linear. The brake pressure applied seems to change when the car downshifts to 2nd and 1st when coming to a stop. It makes the car jerk a little bit. It also seems to shift hard and at odd times sometimes. Any one else have similar experiences. Thanks.
