I'm sure this topic has been discussed & I've noted NWK has mentioned it.
Last season was short because of our back country ban due fires in BC, so this shifter annoyance went it away......well its back

You don't need to bother looking up in the service manual how to adjust, that will just add to the frustration.
What I discovered when I tried to adjust the rod was a compromise between going to low range or Park.....never really working nicely.
Yesterday I removed the center console so I could watch the linkage & try to adjust again. Looking @ the lever coming out of the crankcase I could see the compromise when adjusting the linkage rod. On the shift box there are three bolts holding the top cover, I removed the top cover & re adjusted the linkage again. This time when adjusting the linkage rod, no compromise going into low range or back to park. Click click every time with the shit drum moving into its correct position. When I watched the lever coming out of the crankcase it would go very slightly past the indent in the shift drum inside. Then fall back nicely into low range or park, the other gears & neutral all seem to much happier going into the correct drum position for each gear.
Now that the linkage is adjusted corrected, let's put this sucker together. As soon as I bolted the top cover of the shift box back on the low range shift issue returned. WTF &

, the top cover has indents & a roller that follows these. The indent for low range does not allow the shift lever to travel far enough & correctly into low range. A very quick modification with a foredoom to allow full travel & it works correctly.
When you reassemble everything you will find the gray top cover for the console will now need a slight modification. The shift lever will touch that going into low range, a slight opening of that slot will allow the shifter properly into low range.
With it all back together & a few short test spins, it shifts very nice. You can still load the gear box so it does "not" want to shift & you have rock or move it. Over all it shifts smooth & easily......much better

How I determined the correct adjustment for the linkage rod. With top cover of the shift box removed, you are working with the shift drum indents in the transmision only. Watch the lever coming out of the crank case, in Park & low range the lever will go slightly past the indent & click nicely into position. Adjust for equal amount going past the indent.
When I do this again I will take some photo's & update the post.
