The transmission began malfunctioning by having hard shifting issues and losing power in some gears. An indicator on the dash lit up resembling a mechanics open-end wrench. Research online showed that the vehicle should not be driven and taken immediately to a mechanic or dealership. If driven especially pulling a heavy load like the fifth wheel that I bought the truck to tow the transmission could fail causing a serious safety issue. I immediately took the vehicle to a certified Ford dealership. At the dealership they informed me that parts in the transmission had failed and that it was the same exact condition as shown in recall 20S33. The noted recall was for trucks manufactured in January and February of 2020. My truck was manufactured March of 2020. The time warranty had expired for the vehicle but the mileage warranty was for 60,000 mi and the truck failed at $29,800. The transmission failed due to a manufacturing defect but I was billed over $9,800 for the repair. I have attached photos of the work order and receipt.

I am the owner of a 2020 Ford F‑350 equipped with the 6.7L Power Stroke diesel engine. My vehicle is subject to an open safety recall, the federal safety agency 24V957, involving the high‑pressure fuel system. I have been informed by an authorized Ford dealer that there is currently no effective repair remedy available. While I have not experienced loss of power, my vehicle has exhibited abnormal transmission shifting behavior beginning around 40,000 miles. This concern was documented by the dealer and described as normal operation. The condition persisted and was documented again around 60,000 miles, although the dealer stated they could not replicate the issue. Given the unresolved safety recall and ongoing powertrain behavior, I am concerned about vehicle safety, drivability, and long‑term reliability, and I am submitting this complaint to document the risk before a safety‑related failure occurs.

Truck started jerking and shifting hard when driving. Contacted ford and they said that they needed to do a software update. Did the software update and it got extremely worse not wanting to shift into gear. Take the truck to ford in November to have fixed said I needed a new tranny. My extended warranty approves a used one they put it in same thing happening. Send that one back and put another one in same issue with that tranny. It is now March and they cant find another used tranny to fix my truck. After reading many things online it comes down to the CDF drum the bushing/sleeve moves inside the drum. Ford is aware of this issue and has upgraded/revised a drum. Why is this not a recall issue?

I own a 2020 Ford F-350 Super Duty (VIN: [XXX] , mileage: ~20,000). The vehicle is subject to a recall involving the transmission output planetary four assembly replacement. Ford and the dealer insist that the transmission must be disassembled and rebuilt to complete this recall. I do not agree with this solution because it permanently alters the integrity of the original transmission. Additionally, the dealer (Route 23 Auto Mall, Butler NJ) has repeatedly mishandled repairs, including installing the fuel filter incorrectly multiple times. I have opened several case numbers with Ford Customer Service: Recall Case No: [XXX](02/02/2024) Fuel filter dealer error: [XXX] (01/06/2025), [XXX] (01/15/2025), [XXX] (08/26/2025) Transmission recall follow-up: [XXX] (02/25/2025) Buyback case (denied): [XXX] (03/04/2025) Despite multiple cases, Ford refused to buy back the vehicle because it is registered under a company name. This is unfair and leaves me with a defective and unsafe vehicle. I request the federal safety agency to investigate this recall and require Ford to provide a new transmission replacement instead of a rebuild, and to review Ford’s handling of dealer errors and warranty obligations.
