I recently updated to a new system for three days and discovered a serious issue for me. The old system, although it would jerk a bit when decelerating to 40 km/h, didn't have any other problems. However, after upgrading to the new version, there's a significant shift shock from 0-40 km/h. You can feel the car shake a bit when shifting gears, which was not an issue with the old system. Regardless of the speed, there were no noticeable jerks before.
