2008 Jeep Grand Cherokee 3.7 A few weeks ago I went to start my Jeep and it wouldn't even crank over so I thought my factory battery was finally bad. Bought a new battery and still the same problem. I tried to check fuses and nothing worked. Set for a few days and then started right up like nothing ever happened and so problem in that area since. But a week ago my Jeep started to overheat and then send a message "trans over temp". Parked it and got a new low coolant temp sensor, thermostat, and coolant. But still overheating and throwing the code P0117. Any info on each problem is appreciated. Thanks
