Over-the-air update PCM-25.6.1 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.

| TSB 26-2408 | 2026-09-30. Service bulletin. This bulletin supersedes 26-2309. Reason For Update: update the Model section to remove Aviator 10R80, update the Parts list to add 3.3L to W520514-S440, and add L1MZ-7Z490-G valve body separator plate for Aviator. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh 3-4, 4-5 upshifts * Harsh 5-3, 4-3 downshifts * Harsh reverse engagements These symptoms may be worse when cold. This may be due to the F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177). |

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). |
| TSB 26-2241 | 2026-05-18. Service bulletin. This bulletin supersedes 25-2587. Reason For Update: update the Parts list to add the F-clutch friction plates HL3Z-7B164-D and the F-clutch steel plates PR3Z-7B164-A for the proper vehicle lines, replace the transfer case mounting bolt part number from W714288-S438 to W714288-S437, update the part number W720688-S439 quantity from 2 to 1, update the part number ML3Z-7869-C claim quantity from 2 to 1 (only if necessary), update the description of CXT-10-LV6 and XT-10-QLVC by adding "transfer case fluid, 4WD only", move HL3Z-7A191-B and L1MZ-7F396-A fluid pan gaskets to the parts to inspect and replace list, and remove TL1Z-6775-A self adhesive heat shield from the F-150/Expedition/Navigator parts list as it is not a discard item. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh 3-4, 4-5 upshifts * Harsh 5-3, 4-3 downshifts * Harsh reverse engagements These symptoms may be worse when cold. This may be due to the F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177). |
| SSM 54719 | 2026-04-10. 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 |

| TSB 26-2112 | 2026-03-23. 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 25-2587 | 2026-03-23. Service campaign. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh 3-4, 4-5 upshifts * Harsh 5-3, 4-3 downshifts * Harsh reverse engagements These symptoms may be worse when cold. This may be due to the F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177). |
| TSB 26-2059 | 2026-03-04. 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 54593 | 2026-02-27. 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. |
