I have an 06 rancher es and have recently had the angle sensor replaced. Now I am having another shifting problem. I am getting an 8 code. Now when this happened I was riding 25-30mph, the code came up. I shut atv off turned back on shifted back to neutral and started, up shift button would not work. so I pull manual shifter out and got it back to the house, reved it up a few times and the speedometer would go crazy. I then shut it off it set for about an hour, I started again everything good now. What is the problem here anyone know. Thanks

I just checked codes, and I have a 3 and 8. it is running now though.
