I know a bit about those trannies and I don't have a clue what your talking about from your description. Does the car go forward? Does it go reverse? If it goes forward does it shift ever?

What does binding and tighteninmg up mean? The connotation I get from this is that you are in two gears at once; probably due to reverse failure. If this is the case, it will have to come out and come apart.

The tranny is not electrically controlled except for 5th gear. No codes.
