I have no idea who scotty kilmer is, nor why I should care?
The mechanic trans theory is humorous at best. I suspect you made it up anyway. The stuff described simply does not happen, even if it was his theory
The fluid level is OK per the OP, it has been suggested repeatedly that he check it. I would reccomend the method in the Bentley manual over some sort of silly panic stop trans fluid check.... unless you follow up with your italian tune-up
