NHTSA Complaint #11659011 — 2015 FORD F-150

I noticed in the fall of 2024 that my transmission stared shifting hard between 30-40 mph during acceleration. I had the local Ford dealership check out the issue and they stated I needed a new transmission and included an estimate. I decided to seek information from 2 independent transmission shops and they could not confirm that I needed the transmission replaced at that time. The vehicle has been driving fine and I recently started to notice the hard shift again at 30 mph. Every once in a while, when the hard shift occurs, it seems like I lose power to the drive train and my vehicle slows down to about 15 mph and vehicles need to go around me. It only lasts for a few seconds and then the acceleration will continue to drive normal. I do notice an increase in RPM's from time to time as well while shifting around 30 mph but does not feel like it is slipping. Once through this area of shifting, the vehicle operates normally shifting through other gears. There were no warning lights or other symptoms leading to this issue. I did notice that there was an article posted with a possible transmission issue from this year vehicle that is being investigated concerning sudden down shifting while driving. Here is the article [XXX]. I am wondering if this is part of this issue? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
