Trans Pump Bearing Spun

06 V6 4runner, my daughter was driving it, said it starting losing power, couldn't get above about 45. She finally made it to a park lot, after it cooled, I got there, started it up, put in drive, ok, no reverse. I kill engine and in about 20 secs of run time, it dumps, probably a gallon of trans fluid out the front seal. I pull the trans, and found the seal blown, with the pump bushing stuck to the converter. I'll post some pics shortly.

First pic is part of the seal on the side and the bearing/bushing is siezed on the torque converter. Second pic is after its cleaned up. I checked the pump, bushing drops in loose, so obviously is had been spinning. Anyone seen this before?
