Related recalls
- POWER TRAIN:AUTOMATIC TRANSMISSION
Ford Motor Company (Ford) is recalling certain 2020 Super Duty F-250, F-350, F-450, and F-550 vehicles equipped with 6.7L diesel engines. A washer within the vehicle's transmission can disintegrate, causing metallic debris to become lodged in the 'Park' mechanism.
Risk: Debris lodged within the 'Park' mechanism may prevent the vehicle from achieving or holding 'Park,' increasing the risk of a vehicle rollaway and a crash.
Remedy: Dealers will replace a gearset within the transmission, free of charge. Owner notification letters were mailed on April 19, 2023. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 22S22.
- POWER TRAIN:DRIVELINE:DRIVESHAFT · STRUCTURE:FRAME AND MEMBERS:UNDERBODY SHIELDS
Ford Motor Company (Ford) is recalling certain 2017-2022 F-250 and F-350 Super Duty vehicles equipped with gasoline engines and aluminum driveshafts. Underbody heat and noise insulators may loosen and contact the aluminum driveshaft, which could damage the driveshaft and cause it to fracture.
Risk: A fractured driveshaft can cause a loss of drive power, or a loss of vehicle control if the driveshaft contacts the ground. Additionally, unintended movement could occur while parked if the parking brake is not engaged. Any of these scenarios can increase the risk of a crash.
Remedy: Dealers will inspect and repair the driveshaft as necessary, and properly attach the underbody insulators, free of charge. Owner notification letters were mailed on April 7, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 22S09.

Ford Motor Company (Ford) is recalling certain 2020 Super-Duty F-250, F-350, and F-550 diesel pickups. The transmission torque converter damper plate was not tempered, resulting in a brittle damper plate that may fracture and cause the engine to stall or require increased brake pedal effort in order to stop the vehicle.
Risk: An engine stall or requiring additional braking effort to stop the vehicle can increase the risk of a crash.
Remedy: Ford will notify owners, and dealers will replace the transmission assembly, free of charge. This recall began July 6, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S33.

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)

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.…
