Please help. Odd sound from underneath truck.

I have a 97 f350 with a 7.3L. Today leaving school it started making a sound I’ve never heard before. At first it sounded like the turbo but then after some driving I got home and realized it wasn’t the turbo. Every time I would change gears it would make this sound that almost sounds like a seatbelt belt scratching. The tranny oil is good and I have no idea what else would make this sound. It’s an automatic. I do have a video of the Sound. It is a 4x4

Did you look under the hood to see if you picked up something like a branch or a bag that's now rubbing against the serpentine belt?

Agreed ^^^ only to add that maybe the exhaust heat shield has broken away and rubbing on the driveshaft.
Additionally, have checked the power steering and transmission levels?
