NHTSA Complaint #11616287 — 2020 FORD F-350

My 2020 Ford F-350 has had an occasional problem with the transmission since shortly after I purchased it. It started with sticking in gear occasionally to the point where the engine RPM's would stay very high but not shift even when pushing the accelerator even more. It just would not come out of it. The dealer didn't find any issue and the issue subsided a bit, but in the last 6-8 months, it has noticeably shifted hard into drive, but not when shifting into reverse. Putting it in drive even with the brake depressed hard to the floor, it jolts forward and shakes the entire truck. When downshifting, it sometimes does it so hard that it feels like a vehicle hit the rear of the truck. There is nothing smooth about this truck with the behavior this transmission is showing. I changed the fluid and filter 6 weeks ago and it's the same. It also occasionally revs up when accelerating as you turn a corner and it "catches." I am mostly a daily driver that occasionally tows a boat or snowmobile trailer. Non-commercial user.
