Transmission Gear Slipping problems of the 2011 Ford F-150

When accelerating the vehicle transmission slips into a lower gear, downshifting improperly causing a bump in the ride and a danger in clean acceleration. This issue occurred multiple times and is a contributing power train issue.

I am an owner of a Ford F-150 platinum. The VIN is (xxxxx). I received a notice of a recall with fix for my pickup last year. I took my pickup with the notice that I had received in the mail to our local Ford dealership, baugh Ford in clanton, alabama. I had an appointment with the local dealership on or around September 5, 2018 to resolve this issue. Prior to this repair, I had not noticed or experienced any problems with the transmission. However, following the repair, I noticed the transmission slipping or for lack of a better term forgetting what gear it was in. This seemed to happen while traveling slowly as in a parking lot, then letting off of the accelerator. As soon as the accelerator was depressed there was a brief pause followed by a loud metal to metal pop and jolt as if someone had hit the rear of the vehicle. This occurred infrequently and I could not make this happen, not reproduceable. This occurred approximately six times since September last. On June 15, 2019, while traveling on interstate I-65 north just north of montgomery, alabama at highway speed, I noticed the transmission seemed to momentarily slip or go into neutral. The gear selector was still in drive position and remained in that position through out this incident. Then it seemed as if the transmission started shifting gears. At some point the rear tires locked and the vehicle veered to the right and I and the truck abruptly left the interstate. I went down a steep embankment. I finally managed to stop my vehicle, without hitting any other vehicle or highway signage, near a secondary road. I then moved the gear selector from drive into the park position and then back to the drive position and drove a short distance to a safer location. I exited my vehicle and walked around and looked underneath the vehicle. Additionally, there no warning lights, no error/malfunction codes.
