Transmission Over Temp Jeep Grand Cherokee 2007. To see an open circuit condition when the shifter is in the. At first i thought it was the battery but.
After turning the key to the off position after cranking the display will say transmission over temp for about 3 se. Radio, lights all over so i don't think it could be the battery. The temperature signal is transmitted to the tcm only when the reed contact of the park/neutral contact is closed because the tcm only reads atf temperature while in any forward gear, or reverse.
