Need help! My auto trans is making a sound like a Skil saw. I opened up the transmission and the drive side, behind the moveable part, is awfully loose. It appears the fins are hitting the metal plate behind it. It wobbles when I move it by hand, sqeezing it on the belt. I didn't have an impact socket big enough to take it off. I searched around on this site and didn't see anything with a similar problem. Is this odd? Any ideas? How do I get that first nut off. (no jokes, please) Impact wrench do the trick? Thanks all.
