2015 Ford F-150 Transmission Problems

The component is the 6R80 transmission; the transmission is not available for inspection as i purchased an entirely new unit through ford. After having ford service department technicians perform the recall service, my vehicle began shifting erratically over the course of a few weeks. When I reached back out to the service department I was told- "It will take time for the vehicle to go through a re-learn procedure." I was instructed to give it a few weeks. After about 2 weeks the vehicle began shifting erratically between 6th and 3rd gear at highway speeds. It would randomly hold gears and then skip multiple gears; these issues began and progressed drastically in a span of 2 days. After this issue occured i took the vehicle back to an authorized Ford service department only to be told that the vehicle would need a new transmission and that the update would force the vehicle to "clear/reset, the system after every shutdown." Furthermore the vehicle would only display an error or warning light momentarily before locking the transmission in gears 3-5. At which point the warning light would disappear, after the "limp" mode. Once in this "limp" mode the vehicle would again randomly downshift in 1st or 2nd gear and then jump to 6th.
