2003 Intrepid transmission/sensor heating question
So I have a 2003 Dodge Intrepid with the 2.7 motor. The transmission runs/shifts fine until it reaches normanl operating temp, 222 according to the computer. Then it drops into low range/limp back mode and will not shift past second gear. Ironically as soon as I stop driving it dropping the temp below normal operating temp it drives/shifts fine again. The codes are p0871 and p1776. Is this a cooling problem or a transmission problem.
