When I do launches (car at sport+ and gearbox in sport mode) the gear shift is very rough (especially from second to third). It almost feels like the car jumps at gear shifts. After the discovery I did full software updates and nothing has changed. I'm guessing the fluid has something to do with it (nothing else has changed). Also, after the launches the car shifts rough at Comfort+ mode for a few days. After that the roughness goes away. The gearbox is always adapts according to different drive styles and conditions.

Sorry to hear about the tranny problems. This was the concern with changing fluid outside the 60k window. It seems like some people don't have problems and unfortunately others do. I think the way to go would be to wait until you have some problems before changing the tranny fluid if you missed that window.
