What caused damage to reactor shaft

Looks like the bearing on the stator was coming apart and chewing up the support shaft. I would imagine the remainder of that bearing went through the converter and laid some fins over causing your stall speed to change. Have the converter cut open by a converter shop and you will have your proof.

I agree with your analogy. The converter is on the way to Tsi to be looked at. As far as what kind it is, turn key car so who knows. Google of the numbers comes up empty
