I’ve got about 600 miles on mine now, and I’m currently in Moab for a week. Mine still screams! I’ve checked the sub trans level several times since first adding oil to bing the level to where it should have been from the factory and it’s still showing full. My solution was to buy and install the Rugged Radio intercom/radio system with headsets. Expensive solution to a problem I should never have had. Not only do the headsets give much needed relief from the screaming engine/trans noise, but my wife and I have found we really like the intercom system. No more yelling to hear each other over the wind or engine noise, no hearing fatigue at the end of a long days ride. We can just speak in a normal tone and volume and communicate effortlessly! We can also Bluetooth music from our phones through the headsets so no more cranking up the music to try and overpower the engine and wind noise. All in all a good solution... of course that doesn’t dismiss the problem of the shrieking engine/trans! All I have to do is remove the headset at speed to realize how loud the noise still is! We’ll see if it eventually fails!
