Today, I got the opportunity to test ride a 2019 Rubicon and 2020 Rubicon 520. Both ATVs have DCT.
I can now confirm, while driving in ESP mode (not Auto), if the RPMs drop too low, the transmission will shift down on its' own.
In ESP mode, the transmission will downshift on it's own no matter what gear you are in if the computer determines your RPMs are too low. The transmission will drop from 5th to 4th, 4th to 3rd etc ... While in 5th gear, I let the ATV come to a rolling stop and the transmission dropped from 5th all the way to 1st gear on its' own while in ESP mode.
I have had a 2002 Foreman 450es, a 2005 Foreman 500 ESP and a 2008 Rincon with ESP. I have always driven the ATVs in Manual Mode. I just like to have complete control of what gear I am in at all times. My Rincon has over 30,000 miles and I was looking at purchasing a new Rubicon 520. Now, I am not so sure about it. I am in Canada and the Rincon has not been available in the Honda ATV lineup here for the last 2 years.
I am quite concerned if the transmission shifts from second to first gear when climbing a steep hill and having the front wheels come up when giving it gas while assuming I am still in 2nd gear.
Anyway, thank you for your replies.
