A833 Neutral Issue

UPDATE; So I pulled the side cover off again and counted the input to output shaft rotations. About 2.5+/- to 1. Which tells me it probably has something to do with 1st gear. I put the cover back on and can move the reverse lever into reverse and it locks up. I can move the forward (closest to the input shaft) lever into both gears 3rd/4th, but it still locks up. The rear most lever will only move forward (2nd gear?) past the neutral but not to the rear. Again, locks up. Something to do with 1st gear? Synchros?
