During a modest deceleration or while the car is coasting towards a stop with brake depressed, the transmission will at times seem to downshift in an unsmooth way. Seemingly skipping gears down. The vehicle at times can coast at around 1500 rpms then all of the sudden the rpms jump to almost or around 3000 rpms causing a bucking sensation for the driver. Brake use is affected when this occurs. When the vehicle bucks, the brake pressure can change or is enhanced by the downshift. This can happen pretty regularly during regular driving use and is noticed most during slower driving speeds (10 - 45 mph) and light brake use. High speed braking and heavy brake use do not have this affect as much. Dealer reviewed and could not see any issues. Suggested report to GM - perhaps a software update can smooth out shifting. Noticed first time a day after purchase.
