Transmission jerks and slips. When coming to a stop, the car slams into gear. This could cause a major accident if this occurred during wet or icy road conditions due to breaking traction from wheels and road surface. This is a major concern and after doing some research, thousands of 5 series BMW's have this problem. The result is a defective mechatronics which costs between $5000-$8000 to fix and not covered by BMW or under warranty.

Intermittent harsh 2-1 downshift (jolt) when coming to a stop with light brake application. Jolts and/or jerks felt when reaccelerating after coasting. Judder when gently accelerating (most noticeable at an engine speed below 2,000 rpm).

An excessively harsh 2-1 downshift when decelerating to a stop, or transmission "bangs" into gear when accelerating from a full or a "rolling" stop (vehicle did not come to a complete stop).

When beginning to drive, the vehicle would slam to the point where I thought I was rear ended. I took the car to my mechanic and he said it was the transmission and the fix was costly. Continues to do this at times and will also do a smaller scale slam when slowing to a stop light or stop sign.
