Take the shifter down-rods loose at the transmission. With the shift arms on the side of the transmission housing, see it your can manually shift gears at the transmission. If so, the transmission is probably not the issue and your focus should go the shifter assembly at the end of the mast jacket on the steering column. It is common for this assembly to become worn, out of adjustment or in need of maintenance...or a little of each. Also, it is common for the lower column bearing, to fail and need replacement. In severe cases, the lower shaft bearing has failed and the remainder of the bearing races, have caused excessive wear and removal of a portion of the cross-section of the solid steering column shaft.
