OH-OH
Did you take the shifter apart?
When the vehicle is stopped, it is often hard to shift all gears. Sometimes the parts inside don't line up. Sometimes a brass will screw itself onto a cone real tight, and then it has to be freed by turning the driveshaft.
If you are sure you got the neutralgate lined up AND, all the levers are secured on the tranny, then a road test is in order. The alternative is to get the rear wheels in the air,stick her in first, and ease it out. You may need to ride the brake a bit during the upshifts.I wouldn't try downshifting. The wheels need to be stopped to shift into reverse.
