2021 Ford F-250 SD drivetrain & axles problems

The 10-Speed Automatic Transmission shifts hard and randomly. Leaving a stop sign, at any rate of speed, causes slippage in the shifting. Sometimes it'll shift too slowly, resulting in a jerky motion of the vehicle. Sometimes when on the highway, usually traveling at 68mph (cruise control), the vehicle will randomly jump gears when it's not necessary. Recently while getting up to speed we heard a large grinding noise shifting into 4th gear. The vehicle, otherwise, runs great.
