So had a 700R4 that the bellhousing bolts worked lose on. Here’s what happens when the torque converter get’s in a bind when it moved.

And yes, that destroyed the whole pump. Luckily I haven’t found any shrapnel inside the transmission so clean up and get a new pump and make sure the endplay still good. Going through another pump and getting it ready to put this back on the road with a new torque converter.
