Service bulletins for the 2026 Ford F-650

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. 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.
TSB 26-24062026-09-12. Service bulletin. UNKNOWN OR OTHER; POWER TRAIN. 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.

SSM 549762026-07-07. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. Some 2023-2026 F-53 Motorhome Chassis/F-59 Commercial Stripped Chassis and 2024-2026 F-650/F-750/E-Series vehicles equipped with a 6R140 transmission may be limited to 5th gear and reverse gear only. Additionally, the driver will be able to shift back to park. Diagnostic trouble codes (DTC) P2701, P2704, P0757, and/or P0733 may be stored in the powertrain control module (PCM). 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 tr
SSM 548992026-06-09. Service bulletin. POWER TRAIN. Some 2023-2026 F-53 Motorhome Chassis/F-59 Commercial Stripped Chassis and 2024-2026 F-650/F-750/E-Series vehicles equipped with a 6R140 transmission may be limited to 5th gear and reverse gear only. Additionally, the driver will be able to shift back to park. Diagnostic trouble codes (DTC) P2701, P2704, P0757, and/or P0733 may be stored in the powertrain control module (PCM). 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.

Replacement of transmission components will not resolve this condition.
SSM 545922026-02-27. Service bulletin. POWER TRAIN. 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.
SSM 545592026-02-12. Service bulletin. POWER TRAIN. Some 2026 F-Super Duty and F-650/F-750 vehicles equipped with a 10R140 automatic transmission may exhibit fluid leakage from the transmission fluid pan area. Prior to performing any repairs, thoroughly clean the transmission fluid pan area to ensure accurate identification of the leak source. Before replacing the transmission fluid pan or gasket, verify the torque of the fluid pan bolts and stud bolts. If the torque is incorrect, tighten the pan bolts and stud bolts to the specified torque following the proper torque sequence in Workshop Manual (WSM), Section 307-01. After tightening, verify that the leak has been repaired. If the pan bolts and stud bolts are already torqued correctly, proceed with standard leak diagnosis. Should the diagnosis indicate that pan replacement is required, mark the area of the pan where the leak is present. This information will assist engineering with root cause analysis. For claiming, use causal part 7A194 and labor operation 7000E.

SSM 543382025-11-04. Service bulletin. POWER TRAIN. Some 2021-2025 F-150 vehicles equipped with a 5.0L/5.2L engine, 2021-2025 F-Super Duty/F-53 Motorhome/F59 Commercial Stripped Chassis vehicles equipped with a 6.8L/7.3L engine and 2021-2026 E-Series/F-650/F-750 vehicles equipped with a 7.3L engine may exhibit a rattle/scraping noise upon startup that may remain after the engine is running. This may be due to the starter motor drive gear not retracting after starting. To correct this condition, inspect the starter motor drive gear and shaft. If the starter motor drive gear slides back and forth by hand and/or shows signs of scoring or damage, replace the starter motor following Workshop Manual (WSM), Section 303-06 Starting System > Removal and Installation > Starter.
TSB 25-25152025-10-28. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated MIL with DTC P0384 stored in the powertrain control module (PCM). This may be due to the calibration in the PCM. This condition does not affect vehicle drivability or durability.
SSM 541902025-09-08. Other. UNKNOWN OR OTHER; ELECTRICAL SYSTEM. If the vehicle is built with minor feature code "(IEPAA) - LESS CELLPHONE INTERFACE SYSTM", the vehicle is not misbuilt. Do not submit a claim for this condition. To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS).
