Same problem. 2007 Ford Edge with 125K miles, odo data error, wrench light, airbag light, faulty tire pressure light, speedometer went to zero and transmission stuck in high gear, occurred while driving 70 mph on interstate. Had to push gas pedal to the floor to get the car rolling again from a stop. Parked the car for 2 hours. After restarting the car, the transmission felt like it had fallen out of the car when shifting from park to reverse and from reverse to drive. The problem persisted for about 2 miles, then it "reset" itself and began to drive normally as if nothing had happened. This occurred on a Sunday evening.
Took the car to the dealership the next morning, October 26th, after receiving error codes P0720 and P0722 from advance auto parts. The dealership replaced the TSS and OSS.
Nov 11th, the problem repeats itself with all of the same error messages listed above. I have the car towed to the dealership. Dealership informs me that my battery is dead and they cannot run diagnostics on the car with a dead battery. The battery is only 1.5 years old at this point. Dealership replaces the battery, but is unable to diagnose the problem since the electrical system has been reset from battery being disconnected. I am advised to drive the car as normal and the next time I experience the problem, to drive it straight to the dealership without turning the car off (if I'm lucky enough to have it happen during business hours) as they cannot diagnose the car without the error lights on.
Dec 4th, I'm "lucky" enough to have the problem present itself again on a Friday morning en route to work. I turn around and head straight for the dealership. I park the car and leave it running so my service coordinator can experience the transmission problems for himself by driving the car into the service lane. He also leaves the car running. I receive a call later that afternoon informing me that they know for sure that the smart junction box has to be replaced, as it is shorted out, and that they are getting the same P0720 error code again, but that they can not figure out why the tire pressure sensor and airbag sensor lights were coming on - they can't get my car to produce codes, because the technician COULD NOT DUPLICATE the problem. turns out the service valet guy TURNED MY CAR OFF. When the technician went to restart it, he could not duplicate. As you can see, I'm beyond frustrated. any help or advice is greatly appreciated.
