Automatic Transmission Control Module problems of the 2018 Ford Mustang

My 2018 Ford Mustang ecoboost with the 10r80 automatic transmission began experiencing hesitation, delayed engagement, and harsh jerking during low-speed acceleration (15-20 mph), especially when cold. Engine rpm would increase, but the vehicle would hesitate before engaging. The condition worsened over time and eventually the vehicle entered limp mode, causing a significant loss of power and illuminating a wrench warning light. An authorized Ford dealership diagnosed dtc p07f6 (gear 9 incorrect ratio). The dealer verified fluid level, updated the pcm, and performed adaptive relearn procedures, but the problem remained. The transmission fluid was found to be dark with a burnt odor, and the dealer diagnosed an internal transmission failure requiring complete transmission replacement at an estimated cost of $9,250. This created a safety concern because the vehicle did not consistently accelerate as expected when entering traffic, crossing intersections, or merging onto roadways. Delayed engagement and loss of power reduced the ability to accelerate when needed. The vehicle has approximately 82,256 miles and has been maintained according to Ford's recommended service schedule. I am also aware of numerous publicly documented owner reports, technical discussions, and litigation involving the Ford 10r80 transmission used in vehicles from this generation. One of the commonly discussed concerns involves the cdf drum design in earlier 10r80 transmissions. My understanding is that Ford later revised the cdf drum design in subsequent production; however, when I contacted Ford regarding this transmission failure and requested assistance with repair const, they advised that my vehicle was not covered by any recall, customer satisfaction program, or warranty extension related to this issue. I am submitting this report so that my experience can be considered together with other reports to determine whether a broader safety-related defect exists.
