Note, to adjust you just need to loosen the two side bolts and loosen the top clamp bolt to adjust, the side bolts are removed and the clamp slid down for clarity.

Pic #1 shows the shifter misadjusted. You can see the selector has gone between the two shift arms and is the cause for the "being stuck in two gears at once" or "it won't shift at all" complaint.

Pic #2 shows the lower "cam bearing" turned counterclockwise in the slot removing almost all slack between the parts, don't remove all clearance or it will get too tight, I would guess about .010 would be plenty. Notice with the shifter adjusted like this it is almost impossible for the selector to get caught between the shift levers.

Pic #3 shows a better shot of the alignment guide and the use of the proper 3/16 drill bit alignment tool. Now I better go sweep the carpet before my wife sees the mess !!!

Hope that helps
