Speed Sensor Problems of Ford F-150 - part 2

I was traveling along I-85 about 70mph in my 2013 F-150 stx 5. 0 when out of nowhere the truck down shifted from overdrive to 2 gear the truck started wheel hopping and barking the tires and was nearly uncontrollable! I was almost hit in the rear several times until I could limp it to the shoulder and if anyone knows the area I was almost in charlotte nc traffic is terrible. Once I gathered myself noticed the seatbelt light came on odometer showed 2 dotted lines with the a wrench sign, also tried to take off aging little power speedometer was not working and would not shift out of 2nd gear. I stopped and cut the truck off and waited about 5 minutes and seem to be okay. The very next day going down the highway about 55mph and it did the same thing except this time the back wheels seem to have locked up and when it let loose I almost got hit trying to the shoulder once again did the exact things as the day before still no check engine light. I called the local dealer and was told nothing could be done until a check engine light came on. Once again after letting the truck set for a bit it seemed okay. So for about 3 days it run fine and I was to leave the next morning for out of town work and my truck is the only means of transportation and just as I pulled from my house it started to act up and the check engine light came on just so happens I live near a parts store chain and the person put the code device on and the code came up with I believe it was p 0720 which was the output speed sensor switch located in the transmission. . Dealer repaired at a cost of $987. 00 that I paid that hurt my wallet. I called Ford customer service and the agent said that it has happened to other years with same code and the same fix and would open a case to see if there is a way to get Ford to pay, so I am keeping my fingers crossed.

Driving on highway at 70mph, I saw my speedometer momentarily drop to 40mph. It did it again about 15 seconds later, and downshifted to about 4th gear momentarily. About a minute later, still at 70mph the speedometer dropped, and the transmission downshifted to 1st gear! my rear wheels locked up, and I lost control, and fishtailed for a few seconds. Luckily I had taken a half day vacation and was not in rush hour traffic. Still other cars had to swerve to keep from being hit. The dearlership was able to reproduce the problem, and replaced a moulded plastic module made by continental that I think contained the transmission speed sensor. So it appears that when the transmission speed sensor signal is lost, the failure mode is to downshift to 1st gear no matter the speed of the vehicle.
