I’ve got a 2020 roadmaster elite with 3000 miles on it. I’m traveling yesterday I had a problem shifting. Very intermittent but when I was in 6th gear and need to downshift it went to 5th but then the spring in the shifter didnt lift the pedal back up so I could go down to 4th. I had to take my toe and lift it slightly so I could downshift to 4th. Likewise with all the gears. No problem up shifting just down. It started working properly again but later on same problem occurred. Any thoughts?
