So I have a 2009 rancher 420 a/t. The automatic shift will downshift, but not up shift in auto mode on takeoff. The electric manual shift mode is very slow or sluggish to shift from 1st to 2nd then to 3rd. And very hard to get into 4th. It won't go into 5th at all on its own.
I've replaced the cdi, main body control, tps, shift motor, and battery.
Nothing has changed
Still no automatic mode going up through gears. Any one else had this problem or understand what may be happening
