My car is a 2014 Cruze Diesel with 24,500 kilometers. I got it in August of 2014 and this issue presented itself as the weather became colder that following winter. When shifting from 6th gear to 5th gear, it will give a light jerking feedback as if the RPMs were too high and you throw it into a low gear too quickly. It is the north american model so it is an automatic. I'm not using the manual shifting mode when this happens (although I have tried it and the issue presents itself in both situations, whether the RPMs are low enough for a proper shift or not.) I called the dealer and they weren't too sure and said to drop by any time when it happens. I've caught it happening a few times since then but nothing consistent enough for me to be able to go to the dealer and have them notice it. I figured I'd post here and see if anyone else experiences this and if it's normal for this type of transmission or if I should have them look at something specific. I am aware this transmission does shift a little rough sometimes especially in cold weather. This issue presents itself even after the vehicle has fully warmed up in cold weather. The issue also was present before I started running with the Trifecta tune. The tune has not made the issue better or worse.
