thanks for the add.....I have a 2012 420 rancher es with 1600 miles on it . When it runs for a bit and gets warm, shifting from neutral to any gear results in a blinking dash mark on the speedo, and shifting doesnt happen......never happens when its cold, however, it does shift into gear with a jerk. And general shifting does seem rougher.....this machine is a one owner since new, and rarely leaves the land I live on. Any suggestions? this problem just started up after I chnged the oil. always ran Amzoil 0-40, but used amzoil 10-40 this time......dont know if that is relevant?
