# Service bulletins for the 2025 Ford F\-550

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

109 bulletins from NHTSA, as of 2026-10-19.

- [SSM 55239](/bulletins/11038444.md), 2026-10-13, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM; SERVICE BRAKES. Some 2023\-2026 F\-Super Duty vehicles equipped with a trailer brake control module and built on or before 08\-May\-2026 may exhibit a "Trailer Disconnected" message after cycling the ignition off and back on with a trailer connected. This may be due to the presence of an integrated battery charger on a trailer equipped with electric over hydraulic brakes. If trailer functionality is restored after unplugging and plugging the trailer connector back in while the ignition is on, this condition can be corrected by downloading and performing the "Trailer Brake Configuration" application using the latest software version of the Ford Diagnosis and Repair System \(FDRS\) scan tool. For claiming, use causal part 19H332 and labor operations 12651D and 12651D4.

- [SSM 55218](/bulletins/11038166.md), 2026-10-06, Service bulletin: POWER TRAIN; UNKNOWN OR OTHER. For 20202026 vehicles equipped with the 10R140 transmission, a new Transmission Clutch Circuit Leak Test has been introduced in the Ford Diagnosis and Repair System \(FDRS\). This test utilizes the pressure and vacuum transducer \(PVT\) when available. Workshop Manual \(WSM\) updates related to this diagnostic procedure are planned for release in Q4 2026. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method. The previous air check procedure has been shown to produce a high rate of false positives, which may lead to unnecessary repairs when no actual leak is present. Accordingly, the air check procedure is not to be used for diagnosing internal transmission hydraulic leaks or as justification for transmission replacement.
