904 / Slant six - No Reverse problem - broken band?

If those are the pics of your trans. the very last one might hold a clue. The throttle pressure linkage looks like it's been welded on. (NOTE: their always welded there but this one looks like it has been re-welded). Maybe some time in the past it broke and someone left part of it in the pan? I modified the picture with text and an arrow pointing to what I'm talking about. Is the piece about that size?
