Rancher shifting difference 04 vs 13

I have posted a few times here about ho unhappy I’m with the way my 2013 rancher 420 Es shifts. With 60 miles on it, its very loud when shifting, nothing smooth about it. You can hear the shift motor every shift. Every shift you hear a Loud clunk.

Had the opertunity to test ride a rancher FA 2004 4500 miles for a neighbor that just bought it and wanted my opinion on his new ride. In auto I could not hear or feel it shift in any way! I would swear it was not shifting, but the display was showing it. Super super smooth like wet ice on wet ice! Now switched it to manual shift. Same thing! Every shift shifted so smooth you could not hear or feel it shift in any way. It was just awesome! I was amazed..actually fell,in love with the electric shift.

So…my question what the heck is the difference in the shifting systems in the 13 420es. And the 04 400 FA ranchers?
