When I'm coming to a stop, I'll usually just use engine/lever braking to slow me down most of the way and just leave it in whatever gear I was in before slowing down. As I get near 10MPH or slower, I'll shift it all the way back into 1st and when I do, there's a significant clunk that feels much heavier versus downshifting into other gears while moving. Should I not be shifting back into 1st while still moving? Am I destroying the clutch mechanism?
