I had the exact same symptom with low range and after a lot of screwing around with cable adjustments I took the machine to another dealer and they found that the sub trans had been overfilled with oil (by my original dealer). They drained it and re-filled and I was good to go.
Alright guys so after some phone calls to the surrounding dealers with no help... Well one said bring it in we'll split the trans and see what's going on. How about um no... I carried it to my local shade tree and had him help me diagnose the problem. Needed more hands.
It is exactly as you all describe. It was the smaller sleeve had left the crimp on the shift cable. You could see the cable buckle in that area behind the rubber sleeve. We cut the rubber sleeve away from that area. (Cable already broke so why not?) Now this is where the shade tree came in to play. He slid the sleeve back into position grabbed his trusty vice grips and then grabbed the very edge where the rubber boot was cut away. He then re-crimped the end using just two sides of the stationary piece that is attached to the motor. Man do I wish I taken pictures of all this. It grabbed the smaller piece that had broken pretty well. Slipped him a $50 because he had put a fuel pump in my little boys rzr 170 and that was $40. Gotta love them shade trees! Now to order a shift cable.
Thanks guys for all your help. Hopefully this helps someone even if they are out on the trail. You can manually change the gear on the side if the trans by hand as long as it matches the position on the dash. the location is by your right foot under seat. If you have a set of vice grips it could easily be temporarily fixed on the trail to get you back to the truck.
Oil changes, air filters, rear diff (under warranty kept puking out front pinion seals), now shift cable, not bad for as many miles as she has.
