6R80 lumpy/erratic gear changes

[Yetti2005]

Hi all, over the last few months I’ve noticed the auto box changes appear to be getting more harsh and changing a little more frequently on hills (can’t decide if it wants 3rd or 4th for example) etc. is this likely to be just fluid top up or replacement needed or is it an indicator of something more serious? It’s a prefacelift 2018 with 30k miles… never been on a track but gets some sporadic lively driving on the roads (always within the speed limits obviously )

Any useful advice would be appreciated… cheers!

This may be a long shot but it's very inexpensive!!
There have been several over here that have noticed a change in exhaust notes and it seems that Adaptive Learning may be the culprit.....AL could also be playing a role in your transmission shifting depending on your driving habits??
Disconnect the negative battery terminal and turn the lights on and off....touch the start button and let it sit for 15 minutes....reconnect and give her a test drive!!
Hope this helps ya....GOOD LUCK!!
