This is rather weird. According to the JD dealer, the ..._ fault code is the ground speed sensor, which makes sense according to the described symptoms in the forum and elsewhere. However, when I removed this part (which is illustrated in the operator's manual), transmission oil puked out of its receptacle. I thought this was rather strange. Upon further investigation (after corking the hole) I discover that the part was made by Honeywell, the temperature control company. Since it appeared to be a thermocouple, I concluded that it was the transmission temperature sensor rather than the ground speed sensor. Can anyone shed some sort of illumination on this dilemma? I can't imagine a speed sensor being wet.
