What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
Some 2023-2026 F-Super Duty vehicles equipped with a 10R100 or 10R140 transmission may exhibit an intermittent failure to engage forward or reverse gears and/or a loud whining noise. Additionally, the driver will be able to shift back to park. This may be due to PCM software being unable to command the transmission solenoid clutch actuators when the battery has a low state of charge (SoC) and/or the vehicle has been jump started. To restore proper transmission functionality, charge the battery as stated in the Workshop Manual (WSM), Section 414-01 Charging System > General Information. Cycle the ignition on then off and leave the vehicle off for 5 minutes to confirm the condition is no longer present. To prevent this issue from reoccurring, refer to the Owner's Manual > Storing Your Vehicle > Preparing Your Vehicle for Storage > 12V Battery. Replacement of transmission components will not resolve this condition. Inform the customer that the condition has no impact on transmission durability. For claiming, use causal part 12A650 and labor operations 12650D, 12650D45, and 12650D81.

What owners reported
Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 237 complaints with NHTSA since 2015. 105 of them name Electrical System, Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns a 2024 Ford F-350. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was taken to the dealer but was not diagnosed or repaired. The dealer informed the contact that a software update had been completed on the TCM.

The trailer light control module is intermittently causing trailer light faults messages and signal failures. This is associated to recall 26C10. The software update doesn’t correct the problem. Ford does not have the hardware on hand to replace the failing part. This is a safety issue for us who are on the road towing travel trailers

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54975 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 54975 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 54975 cover?
The manufacturer filed it against 15 model years: 2026 Ford F-250 Super Duty, 2025 Ford F-250 Super Duty, 2024 Ford F-250 Super Duty, 2023 Ford F-250 Super Duty, 2026 Ford F-350 Super Duty, 2025 Ford F-350 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
