I have read the question about the 2000 shift pin coming out but don't have a clear idea of what the problem is or what should be checked or replaced. Hick asked the same quuestion and had a link to the tranny picture to try to help. So could you or someone else point me in the right direction here? I would like to do a preventative part swap but I need to know the part with the disappearing pin. It would be great if someone could reply with the reference number from the link below: http://220.127.116.11/yamaha_DB/yam_DB_webclass1.asp?show_frames=2000YZ426FMTA+2000YZ426FMC4+2000YZ426FMC4.GIF Can someone help us out?
