2021 Honda Rubicon shifting issues.

So.. It has now become cranky about changing from "drive" to "reverse". Sometimes it's seamless as it's always been, other times it just goes "click, click....click, click " when going from reverse to forward, or from forward to reverse..  Then it gives up and just stops at neutral.  Only thing that seems to help is to give it a bit of a bump / wiggle with my own weight. Any ideas as to what to check? It's low miules / hours .. Dealership maintained..

You should check the shift cable is moving the shift lever down on the engine full travel. I don't think that will be the problem though because that bike has a power shift (electrical/hydraulic).

I think it might have a place on the left side of the engine where you can fit a foot shift lever to test the gears and to get you home if the electrical or hydraulic systems that do the normal shifting plays up. They say to fit that lever and try manual shifting early on in the long and complicated diagnosis process.. So if that lever is in the tool kit, fit that and try driving manually.

I'll see if I can find a service manual.

Could only find an owners manual so far.. But it's for the 2020.. Probably right.. Check this pdf and see if it is the same as your model. Try the tests they say..

And I see it doesn't say you can drive it home..  That was older models.

Hmmm.. I probably been more specific about what trans it has.. there's no shifter peg / lever.. there's only a up and down button on the left handlebar. My only other options are a lever that switches from high range to low range, which seems to be a direct physical connection, not electronic. My drive options are 2 wheel drive, press a button for 4 wheel drive, and slide a lever over the 4 wheel drive button to lock the diff. 

It seems to be all electronic. It does have a slide switch to change from auto to manual.. The "click, click, click" problem is present in all drive modes, and is only solved by booty bumping the quad, or, shifting to the desired range while moving slowly. 

There's a little lever just behind the shift buttons, that when pulled in, will make it go from drive to reverse, or reverse to drive, in one shot It really doesn't seem to matter what I do, it just glitches, unless I give it the "secret handshake" ( booty bump)

Well I looked up that bike in the parts sites and it shows it as having a "Double Clutch Transmission", which is described as DCT. Then I tried to find a manual and the nearest manual I could find is the owners manual for the same bike from 2020, so I looked up the 2020 model, and it has the same running gear, a DTC transmission. So.. that bit I posted is describing what to do about faulty gear shifts in the 2020 model, which, as far as I can figure, is the same as your bike.
