Was having late shifts i.e. engine not shifting at proper RPM's but shifting later in the revving cycle. Looked everywhere on VX.net for information and came across many solutions some of which I tried and some of which I did not. Nothing seemed to help. So with much trepidation I removed and dismantled the mode selector switch. After cleaning it, reassembling it and reinstalling it I think things were actually worse. BUT, while reinstalling I noticed that the mounting point for the top bolt is slotted allowing for adjustment. Since I hadn't tightened the top bolt yet I loosened the lower bolt, rotated the mode selector switch as far as I could clockwise and voila problem solved. Proper shifting achieved.

I am only mentioning this here because I could find no other posts on "adjusting" the mode selector switch but only on replacing or cleaning. Hopefully it will help someone in the future. Had I known about adjusting the switch I could have saved myself some time, energy and headaches. lol
