Over-the-air update PCM-26.10.0 Expedition

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.

TSB 26-22632026-06-05. Service bulletin. This bulletin supersedes 26-2112. Reason For Update: add 2026 model year vehicles, update LV fluid XT-10-QLVC and CXT-10-LV6 description to add "Transfer Case Fluid 4WD Only", and update Step 4 to inspect/replace 7H351 and 7B177 outside of this article. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: - No upshift past second gear - Unable to achieve third gear ratio - Illuminated MIL with DTCs P0757 and P2701 This may be due to a damaged one-way clutch (OWC).
SSM 547192026-04-10. Service bulletin. 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 546742026-04-06. Service bulletin. For 2021-2026 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. The Workshop Manual (WSM) has been updated under Section 307-01 > Diagnosis and Testing to include this procedure. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method.
TSB 26-21122026-03-23. Service bulletin. This bulletin supersedes TSB 26-2059. Reason For Update: To add missing labor operations. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: - No upshift past second gear - Unable to achieve third gear ratio - Illuminated malfunction indicator lamp (MIL) with DTCs P0757 and P2701 This may be due to a damaged one-way clutch (OWC).
TSB 26-20592026-03-04. Service bulletin. This bulletin supersedes TSB 25-2423. Reason For Update: Replace the incorrect acronym SOWC with the correct acronym OWC. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: - No upshift past second gear - Unable to achieve third gear ratio - Illuminated malfunction indicator lamp (MIL) with DTCs P0757 and P2701 This may be due to a damaged one-way clutch (OWC).
SSM 545932026-02-27. Service bulletin. Some 2024-2025 F-150, Expedition/Navigator, Escape/Corsair, Bronco, Explorer, Mustang, Maverick vehicles equipped with a 1.5/2.0/2.3/3.5L EcoBoost engine and built on 01-Oct-2024 and through 31-May-2025 may exhibit an extended crank condition, strong fuel smell in the engine oil, high engine oil level and/or may have various drivability diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM) with an illuminated malfunction indicator lamp (MIL). This may be due to an internal fuel leak of the high-pressure fuel pump causing fuel to enter the crankcase and reduce fuel pressure in the direct injection fuel rail. Diagnose this condition using Pinpoint Test HP located in Workshop Manual (WSM), Section 303-04. If no DTCs are stored in the PCM, proceed from Step HP1 to Step HP5 and continue testing. Repair as necessary outside of this article. For claiming, if high-pressure fuel pump replacement is required, use causal part number 9D376 and labor operation code 9543A. If the root cause is identified as anything other than the fuel injection pump, claim the repair outside of this article.
SSM 545922026-02-27. Service bulletin. For 20172026 vehicles equipped with a 10R transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, located in Section 307-01 > Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements (N>R, N>D, R>D, or D>R) should be noted. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article.
TSB 25-26212026-02-17. Service bulletin. Some vehicles listed in the Model statement above may exhibit a no crank/no start condition where the customer cannot start their vehicle. The vehicle may also exhibit a "No Key Detected" message displayed on the instrument panel cluster (IPC), and no key fob works in the back up slot. The remote keyless entry (RKE) functionality will work to lock/unlock the vehicle.

SSM 545032026-01-21. Service bulletin. 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
