It is a VERY WIDE SPREAD PROBLEM and appears to have been acknowledged by Ford with at least two or three part updates.
I went to the Ford Dealer and their transmission specialist told me they had 50-yes 50 transmissions in line for issues. He knew exactly the symptoms. He knew they either appear in 3,4,5 or the higher gears. He knew that before some had a downshift from 10th to 1st (yes-you read that right) when on the highway.
It is not strange at all.
You didn't say what year you had-but if you have 2017 through 2020-you have at least two design issues from the factory. The 2024s have the new parts.
I understand that this is a Ford board-but I'm not getting in to an debate that there are not issues-because there are. If you do not have the ten speed-you don't have issues.

Hi, I had my 2020 F150 into the dealer at 49,000 miles for rough shifting. The rough shifting happens between 3-5 and occasionally in the higher gear like 7-9. I also notice rough downshifts. They reset the adaptive tables but I’m still noticing the rough shifting. I really notice it driving in manual mode and shifting it from like 6-5 and 5-4. How long does the adaptive tables take to learn before I should take it back. They did find the tsb 23-2250. Thank you

Those who have had the adaptive shifting relearn states in almost all cases the symptoms return.
