So I have a 2017 F250 CCSB KR 6.7 with about 71K miles on it. I am the second owner and have had it for less than 2 years and have put about 40k miles on it, I drive it daily back and forth to work about 75miles a day, plus use the bed and tow some stuff nothing to heavy on the towing but can get heavy with the bed. I have already check transmission fluid and the level is correct, smell good, and looks good. There are no leaks underneath that I could see on the case or ground.

I just recently started to notice things going on with the shifting, it seems to be hesitant to shift up or down occasionally and almost seems like it hangs the gear and keeps accelerating harder until it shifts. This seems to be mostly in the 5/6 up shift. the downshift it just feels like its shifting hard from 4 to 3. Then the other day I was going through a drive thru and as i pulled up to a drive through with my window down i could hear a slight whine coming from my truck and once i got a complete stop it could still hear it for a few more seconds until it stopped and when it did I could feel the truck disengage and let the transmission "relax".

Any help or way to point me into the right direction would be awesome.
Cheers!
