Been on the road and just got back. These 12 hour drives are starting to kill me...
The shutter has always concerned me too. And I hear it's the nature of the beast. Initially I tried to equate it to all other clutch operated vehicles I have owned where a shutter indicated something was wrong.
Motorbikes, dirt bikes, any manual clutch vehicle, all the clutches slip, purposefully, it's how you DONT get shutter and have smooth takes offs and shifting. This clutch slippage was normal and designed to slip. So I equated it to like taking off in 3rd gear on one of the above, it shuttered and that meant wrong gear, drop down.
However, this is an "automatic clutch" and NOT a manual and this is what took me awhile to get into my head. That this particular shutter, whereas normally indicative of an issue with manual clutches, in this case, it does not and a certain amount of shutter is going to happen. What you don't want to do is prolong the shutter.
So a little shutter when taking off is ok. A little
Not to confuse a little with how much it is felt or how much it shutters, a little in meaning length of time, for a couple seconds.
Having it shutter for more than a couple of few seconds COMBINED with constantly driving it that way, yes, will wear things out much faster.
And the way to get around that, is to avoid extremely constant low speeds and just give it gas and don't do a lot of poking along very slow.
And if you're really worried about it, just keep it in low. I personally think way too many frown on low and think it's a disgrace or you won't get a badge of honor driving in low. I think too many associate owning a UTV with being in an extreme sport. That's what sport models are for.
Low is there for a reason. High has its uses. Flat or hilly trails, pavement, etc., etc high is fine. For me personally, on any kind of load, over and above normal driving and its low range all the way. It's fast enough for this old man and my shutter all but disappears. I believe that being in high is what caused a lot of the clutch issues you have heard about.
High = speed. Most all others, except me, love to go fast.
But stop thinking shutter means something is wrong. An automatic clutch is a different animal completely in regards to a manual clutch that many of us grew up on
