Sorry, didn't mean to come across as a smart ass. I don't think you are hurting anything at all. I bet most people have done it more than they would admit. The converter not being tied solid to the input shaft has some cushion with the fluid. That being said, the load when you take off it much, much greater than when you are rolling backwards slightly. I certainly can't argue that it is not the right thing to do, but I myself have never worried about it when I have done it. Hope that helps.

P.S. Maybe the people worried about it should use better parts :lol: :lol: :lol:
