Was out in a local state game lands today, puttin along in low range on some of their trails, and every once in awhile, I would get a "ding", but no lights. I know this normally occurs when the transmission overheats, but my tranny temp never seemed to go above 215* (yes, I know, I need a cooler) according to my Aerotech scan gauge. I also used it to check for the overheating code, and there were no stored codes. My temp. never dropped below 192* until we hit the open road on the way home. Will it do this if you sustain a high temp for to long? Or could it be something with the ESP since it automatically switches off for the most part when you put it in low range? I can't recall if it did it only in low or in high also. I lost track of how many times it did it after 6.
