The transmission can remain in 7 gear and not downshift when stopped. The only fix is putting it in park. The transmission also has intermittent rough gear changes and problems downshifting while stopping. Dealership updated the TCM which only made the issue worse. Ford stated that I should go to another dealer to see if they could replicate the issue (local dealer said they couldn’t replicate the problem)

Subject: Request for Review of Recall Remedy Effectiveness – Ford Recall 24S78 / the federal safety agency Recall 24V‑957 Vehicle: 2020 Ford F-250 Super Duty 6.7L Power Stroke VIN: [XXX] To Whom It May Concern: I am submitting this letter to document a significant safety event involving my 2020 Ford F-250 Super Duty and to request that the federal safety agency consider whether the current recall remedy associated with Ford Recall 24S78 / the federal safety agency Recall 24V‑957 adequately addresses vehicles that are already exhibiting symptoms of CP4 fuel pump deterioration. I am not submitting this complaint to seek financial compensation. My purpose is to provide information that may assist the federal safety agency in evaluating whether the existing remedy sufficiently protects motorists from the safety risks associated with CP4 pump failure. Background My vehicle's VIN has been confirmed as included in the affected population covered by the CP4 fuel pump recall. Prior to the ultimate failure, the vehicle exhibited symptoms that, in hindsight, may have been indicators of fuel-system deterioration. In February 2026, I documented concerns regarding abnormal starting behavior and specifically questioned whether either vehicle battery was failing. No battery issue was identified. Believing the issue might be battery related, I replaced both batteries at my own expense. The starting concern continued. On [XXX], while covered under a Ford Extended Service Plan, Fuel Injector #4 failed and was replaced under warranty. During the same service visit, the recall software update was performed. Despite the recall remedy being completed, the vehicle subsequently suffered a catastrophic CP4 pump failure in August 2026. Safety Event The failure occurred while traveling between Utopia, Texas and Tarpley, Texas on a rural roadway with sharp curves, steep terrain, significant drop-offs, and little or no roadway shoulder. The vehicle experienced a sudden loss of propulsion. Fortunately, I had just exited a curve and was able to INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (F

10r140 paired with 6.7 powerstroke in a 2020 f250 build date 11/19 at the Kentucky plant. My truck specs and build date and location is in the timeframe of the planetary gear recall, ford has also issued tsb’s about the cdf bushing that should have been a recall because it is a design flaw on every 2020-2022 model truck. It’s not fair that we should have to pay for a tsb bc we don’t have warranty left. My truck has 84,000 miles but is out of the 5 years warranty period. Symptoms I am having with my transmission are: Harsh engaging to drive and reverse Flair shifts bad sometimes almost like it goes into neutral between changing gears Has shifted from 4th to 1st instead of 4th to 5th or 6th, then it started shifting normal right after. Had my factory 3250rpm limiter not been moved to 4500rpm the truck would have locked the rear wheels up and possible caused driveline damage or other damaged. Also had a car been behind me when this happened I would have been in a wreck because it slammed to a low speed and the car would have rear ended me. Slips in 4th and 7th gear the most but sometimes in other gears Bumps when it shifts a lot of the gears Sometimes shudders and shakes and will almost make like a pop noise Will clunk on downshift from 5-3 Sometimes clunks when upshifting 3-5 I have had the truck looked at by an independent diesel mechanic I use and he said there is a problem somewhere in the transmission, it’s either planetary gear or cdf bushing has moved or the drum itself has cracked. The component itself has not been inspected because the only was to inspect this is to tear the transmission down. The pan has been dropped and had a lot of metal material on the magnet. No codes on the dash but my mechanic said I had dtcs stored for the transmission. I have created a case claim with Ford trying to see if they will extend the recall for the known issue but I have had zero luck with them. I have videos of the issues but can’t upload them on here.

The contact owns a 2020 Ford F-250. The contact received notification for the federal safety agency Campaign Number: 22V256000 (Power Train); however, the recall repair could not be completed. The vehicle was taken to a dealer where it was diagnosed that a thrust washer was missing from the output planetary assembly and had disintegrated, contaminating the transmission case, transfer case, torque converter, cooling lines, and radiator. The missing washer caused the planetary gear to shift and damage the transmission case. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was 80,256.

2020 Ford F250 with 85,000 miles. We purchased new and all maintenance has been done on time and by Ford Service. Transmission began jerking when going from park to drive (or reverse). Noticeable lunging of the vehicle when putting into gear. This began in December 2025. This is a safety concern if anyone is in front of or behind the vehicle when this happens. The truck jumps. Now the transmission is not shifting gears smoothly when the truck is in motion. This is a known problem with trucks manufactured during this time period with 10R80 transmissions. Ford has been less than helpful in helping me come to a resolution. They tell me there was a TSB sent out. They attempted to reprogram software (at a cost of $424 to me). I will upload the invoice from Ford. This only made the problem worse. They quoted me a "special price" of $8,500 to replace the transmission, however their service department is SIX WEEKS out. For this reason we have chosen to have the transmission replaced at a local transmission shop. Their price is $9,932.41. I have attached that invoice. Ford needs to take accountability for this safety problem and attempt to make these vehicles safe. They should absorb at least some of the cost to fix this design problem. We paid full price to purchase a new, safe vehicle. That is not what we received. Rather than a "Technical Service Bulletin", Ford should be forced to do a recall and make this right for customers who paid top dollar for these vehicles.
