Well I was scratching my head on the bellhousing gouging and I think I realized what may have happened.
Another look at the oil pump picture and you might notice that there is no way for the oil pump to engage the torque converter. Both of the tabs are missing. I happened to find one of them though.

Seems like a failure that should have caused a lot more damage.
