From time to time my 04 4.7 RWD Durango will display the warning light for transmission overheating. There is no consistency in when the light comes on, I've checked the fluid and it still is a light red color with no burnt smell to it, I've stopped the car when this happened and checked the fluid( which reads at the full mark to eliminate the suggestion that it may be low or to full) and it is tepid or slightly warm at best. I have noticed that the shifting becomes hesitant when the light is on. When you your the engine off and restart the light stays off. Any advice in this matter would be greatly appreciated.

 

Either a bad connection somewhere, or the sensor itself if failing.
