2020 Ford F-350 SD: complete transmission failure

Filed Jul 1, 2026 · Transmission · AZ

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 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.

The letter from Ford written by David J Johnson director of service engineering operation, dated September 23, 2022.
