Perhaps the problem lies with the flange on the flexplate. It won't affect the balance if you take a grinder to the lip. Just tape a line around the edge and remove the amount you need evenly all the way around. It won't take much and you'll save yourself the money and time of taking it to a shop.



I agree, if you have a grinder, I myself (having a steady hand) would use a cut-off disc on it, heck even a dremel, just buy a couple cups of the thin cut-off disc & have at it, may take an hour or so, run tape around it & cut off about .40"-.050" & your set. If you have a table vice, just snug it up so its steady & go to town .
