Trans Over Temp Msg - Car wont start
Hello, i own a 2008 jeep grand cherokee limited, 4.7L, 50.000 mls. About 3 weeks ago i made a stop at the gas station, turned the engine off and after 5 minutes i tried to restart but nothing happened, only a trans over temp warning on display. 30 minutes later the engine started perfectly. This problem is permanent now, but it got worse, most of the times it wont start even if car is parked overnight. Since last week i have to disconnect the battery for 10 minutes, reconnect it and it starts normally. Once the engine starts i can drive during hours without any error msgs on display, everything works perfect until i turn the engine off. Selenoid Pack and Transmission fluid was changed 3 months ago. I took the car to my local jeep dealer, they said its a failed response from TCM and want me to change the PCM. I did a forum search but i canīt find the exactly same problem i have. Most other trans over temp errors are only flashing for a few seconds when they turn the key off, my msg is not flashing, it stays fixed on the display. Maybe somebody can tellme if i really need to spend over 3000$ for a new PCM, iam afraid this is not the real solution. Here in colombia the oficial jeep service has poorly trained technicians and is a very expensive service.
