I used my 1998 New Holland 8260 a couple days ago and had no problems, so I get in it today to do some mowing and everytime I went to put it in high range or overdrive (23x12 tranny) I got an error code of "E65". My list of codes says this is for a "High Solenoid Open Circuit", i'm just wondering whats going on and how to fix it, as long as I don't hit the rabbit button on the shifter it will work in low range or underdrive, but if I try for high range the tractor stops, the alarm goes off, and E65 starts blinking on the dash. Its kinda weird that everything was fine Saturday and now its doing this!!
