The fill plug on the MTX is sized for a 3/8'' socket drive, right? Mine's stripped internally, the 3/8'' drive won't bite. This MTX has the drain plug mod, and right now the tranny's got no fluid. I need the fill plug out 'cuz right now I can't drive the car. So I guess I need to go shopping for an easy-out. Tight quarters so I hope I can find a stubby one. Anyone wanna suggest a size? VO
