2024 FORD F-250 SD Engine Problems

I purchased my new 2024 Ford F250 on [XXX] with less than 30 miles on the odometer. It includes a 10-speed automatic transmission. I have noticed erratic up shifting and down shifting of the transmission. The problem started at approximately 700 miles on the vehicle. Additionally I have noticed that after initial starting the vehicle, when placed into drive or reverse, the transmission appears to slam into gear as noticed by a large jerk and loud sound. The vehicle continues to sound like there is a mismatch between the engine revving up and transmission lagging behind for some time, or as if the transmission is slipping gears. The new vehicle was taken into the dealership on 6/9/2025 at 7:00AM and work was reportedly completed and vehicle ready for pickup on [XXX]. I was informed that the service technician performed a break-in procedure and that everything was okay. Within 30 minutes...

When you start engine, and it's below normal temp, the engine maintains a high idle rpm and upon shifting to fwd or reverse the truck overpowers the brakes and accelerates rapidly. In reverse it's startling. It's unsafe in parking lots and on street parking.
