Just sharing in case it helps anyone. Bought a 2019 Pilot Elite Demo with just under 5k miles last July. Like it but was bothered by the transmission especially in economy mode. At certain times the up and down shifts were rough especially from 24-30mph. Finally took it in to see if everything was ok. Tech said nothing showed abnormal and it seemed fine to him when he was test driving it. But he said he updated the TCM software and told me to give it about 500 miles to adapt to driving. Well it is has been great ever since. Smooth and gear changes are barely noticeable if at all. Not sure if this is helpful to anyone but really enjoy driving it much more now.
