My 420at has problems shifting to first in auto or electric shift. It does go in gear but show a horizontal bar in the display. If you goose the throttle and drive a bit it will show in gear sometimes and shift through the rest of the gears fine. I have taken the shift motor apart and it is clean. I have replaces the shift angle sensor and cleaned the gears and replaced with synthetic grease. Nothing has changed the symptoms. This bike has 274 miles on it,
What else could it be?
