Check on the pass side of the case is a about 4"X4" cover plate up high. Take that off and you should see the shift rod. The shift fork is held on the rod by a big set screw. If the set screw is lose or gone it will not shift. There is a spot in the shaft for the set screw to lock into. Hope this helps
