# Over\-the\-air update PCM\-25.6.2 Navigator

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.

- [SSM 54719](/bulletins/11031262.md), 2026-04-10, Service bulletin: POWER TRAIN. For 20212026 vehicles equipped with the 10R80 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. When referred to a specific clutch \(A\-F\) test by a pinpoint test in Workshop Manual \(WSM\), Section 307\-01 \> Diagnosis and Testing, the Clutch Assembly tests have been updated with a hyperlink to the new Transmission Line Pressure Test \- Pressure Vacuum Transducer \(PVT\) Is Available procedure in WSM, Section 307\-01 \> General Procedures. This procedure provides instructions to perform the FDRS Transmission Clutch Circuit Leak Test when applicable. 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

- [SSM 54503](/bulletins/11027712.md), 2026-01-21, Service bulletin: POWER TRAIN. Some 2021\-2025 F\-150, 2022\-2025 Expedition/Navigator, 2023\-2026 F\-Super Duty, 2024\-2025 Ranger and 2026 Transit vehicles may exhibit a discharged battery and/or a no crank/no start condition. The vehicle may also exhibit a clicking noise from the trailer module \(TRM\) while the vehicle is off. This may be due to software in the TRM.\<br /\>\<br /\>Verify the TRM software part number in the vehicle using Ford Diagnosis and Repair System \(FDRS\) to be PC3T\-19J297\-BF, PC3T\-19J297\-FF, ML3T\-19J297\-CD or ML3T\-19J297\-GD. To confirm a vehicle is equipped with a certain software level, review the software information by hovering over the "Diagnostics" tab in Professional Technician System \(PTS\) and selecting "Vehicle Software". If one of the listed software part numbers is present, follow the Service Procedure to reprogram the TRM. For vehicles with any other software part number in the TRM, refer to Workshop Manual \(WSM\), Section 414\-01 to continue with normal diagnostics outside of this article. For claiming, use causal part 19H332 and labor operation 12651D and 12651D4 of the Service Labor Time Standards \(SLTS\) Man
- [SSM 54392](/bulletins/11025816.md), 2025-12-01, Service bulletin: ENGINE; POWER TRAIN. Some 2021\-2025 F\-150/Expedition/Navigator vehicles equipped with a 3.5L EcoBoost engine may exhibit diagnostic trouble code \(DTC\) P0299 stored in the powertrain control module \(PCM\) and may also exhibit a rattle noise from the turbocharger. This may be due to the wastegate actuator rod being disconnected. Workshop Manual \(WSM\), Section 303\-04 Fuel Charging and Controls \> Turbocharger has been added to address this condition to allow servicing of the turbocharger actuator rod. In addition, the wastegate actuator rod and associated retention springs and clips have been released as lower level components to complete the repair without replacing the entire turbocharger actuator assembly.
- [SSM 54363](/bulletins/11025526.md), 2025-11-13, Service bulletin: UNKNOWN OR OTHER; POWER TRAIN; ENGINE.
