My speed is limited to only 45 mph in 2024 rubicon. How do increase the speed limit. Older rubicons all go 57-60 mph. This is my work vehicle so this lower speed limits my ability to get things done. Also when shut atv off always goes into neutral. Hauling in pickup older ones always put into reverse keep from rolling around as much. Can this be changed so stays in reverse? This more safety issue. Thanks to anyone
