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 552182026-10-06. Service bulletin. 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.
TSB 26-24062026-09-12. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: Poor shift quality Illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTCs) P2704 and P0771 stored in the powertrain control module (PCM)/transmission control module (TCM) This may be due to sticking valves in the main control valve body and/or damaged E clutch friction plates and/or E clutch steel plates. Additional model information: 6.7L Diesel Engine 7.3L Gas Engine 10R140 Automatic Transmission
SSM 549752026-07-07. Service 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.

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).
ECM-26.10.0 SuperDuty2026-05-15. Over-the-air update. 26E01 Recall remedy -Powertrain Control Module calibration update to ensure emissions system restrictions function properly when the vehicle is parked.
PCM-26.10.0 Expedition2026-04-17. Over-the-air update. Quality improvements include: -Updates the Powertrain Control Module documentation to ensure vehicles can receive the latest updates
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
26E012026-04-07. Other. Certain 2023 - 2026 Model Year F-250 – F600 Super Duty Vehicles with 6.7L Engines Powertrain Control Module (PCM) Software Update The affected vehicles were originally manufactured with Powertrain Control Module (PCM) software that did not provide the correct warnings when certain conditions are present in the Selective Catalyst Reduction (SCR) system as required and described in the Owner’s Manual.
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.
