Well im no expert tranny mechanic but it looks like you might have it in reverse or 1st. The big gear in front is engaged into the secondary shaft gear. Kinda of hard to get a "feel" for what should be and not via pics. I think if you have the knowhow todo a rebuild you can see whats going on. Use a screw driver to move things around while turning the output shaft and im sure it will all sync together.
