Need Help Diagnosing 10R60 Transmission Noise / Slippage (occurs weekly - videos captured)

[Lone Star State Shepherd]

2023 Ford Explorer ST - 16K miles

I purchased this ST used four months ago and the transmission slippage has occurred randomly every seven days or so.

The Ford dealership I have been going to with my last two Explorers says I need to leave the car for two months (backlog) and if it doesn't make the noise when they test drive it they can't help me (despite clear evidence in the videos).

Can anyone help diagnose this issue and recoimmend a remedy?
