NHTSA Complaint #11711122 — 2019 FORD F-150

(Current approx mileage of occurance 104,xxx -105,xxx)The transmission on my 2019 Ford F150 abruptly started to run really bad. The transmission started slamming gears, hard shifting, delayed shifting, delayed acceleration. The shifting was slamming to hard, that it felt like another vehicle hit me in the rear. I called a local Ford dealership on 1/7/2026 to make an appointment to get the software updated (TSB 21-2145), the earliest appointment I was able to get was 1/13/2026. I drove the truck again on Sunday (1/11/2026) for church, and upon returning home, the wrench icon appeared on my dash board. I did not drive the truck again until 1/13/26 for the appointment. I took the truck in on my appointment and shared my concerns with the technician about it being a bigger problem than a software update, and he assured me he would complete proper inspection and diagnostics. After the tech completed the software update (& reset shift tables) the truck drove worse. He informed me, he believes the truck will need a replaced transmission. On my way home the truck drove worse, Slamming gears harder, and hesitating worse, worse delayed acceleration. The truck is not safe to drive. I took it to another reputable transmission shop in town 1/15 for a 2nd opinion, and he concluded the same. Transmission needs to be replaced. The frustrating thing in all of this, is I had an extended warranty on the truck through 100k miles. I took the truck in to the local Ford Dealer for a full inspection at 99,xxx miles to verify all was good, and if it wasn't then I would like to use my warranty for repairs. I was given a bill of good health. And approx 5000 miles later, I now need a full transmission replacement? I am getting no-where with Ford. I even tried my insurance company, and am getting no help there either. I still owe a balance on my truck, and now I've got to figure out a $8k-11k repair.
