Final update on this issue. The shift pin in my previous post was not the issue in this case. After replacing every electronic component on the ATV with no change with the problem. I had to pull the engine back off completely and go through everything with a fine tooth comb. Finally I found an issue that is not mentioned anywhere in the manual, on the internet that I can fine, NOWHERE. Inside the main shaft that the dual clutch goes on there is a brass or copper ring that the feed pipe "A" stabs into. In my case that brass/copper ring was scarred up. Apparently causing a variation in the oil pressure that the computer sensed and made it now allow the bike to down shift. It never threw an actual code. The MIL light comes on steady and does not allow the bike to shift at all. I installed a new mainshaft and now the bike shifts great. I hope this helps anyone who has this issue.
