I have a 2021 stx f150 with just under 4700 miles. It’s been in for dealer for equal time of me owning it for vary hard shifting and harsh clunking from rear end when coming to a stop. They have replaced valve body’s and done multiple resets of shift table. Still no fix. Just feels like even more of a piece of crap 50k$ truck. Looking for help to see if anyone has had similar issues.
