Transmission Stuck In Gear problems of the 2019 Ford Expedition

Event occurs when vehicle is warmed up - transmission fluid temp > 205 and more likely to occur going uphill or on a slight incline on highway with a speed above 55 mph. When accelerating quickly or aggressively, the 10 speed transmission fails. I push down on the gas pedal while in the 10 gear. It seems like it is stuck in neutral, the engine rev's to the red line if I leave my foot on the pedal, the vehicle looses speed and eventually finds a gear between 2 and 6 and transmission re-engages. The vehicle will rev to the red line before finding a gear. This has created multiple dangerous situations in which a vehicular accident almost occurred due to the immediate loss of speed in highway traffic situations. The vehicle went from 83 mph to 55 in seconds before the transmission re-engages. I have take the car to the dealership twice and they can not recreate the issue in order to fix despite submitting numerous videos of the separate times in which the event occurs.
