The front hanging from a boom is probably causing the issue. That would allow the front to push away in an arc like a swing as you try to engage the trans. Set the front on cribbing so it is fixed. Are you on a cement pad while working? Dirt floor makes a little more challenge, have heard folks lay down 4x8 sheets of 3/4 to roll floor jack on if not working on cement pad.
