Service bulletin TSB 24-2255

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.

NHTSA's summary

Some 2024-2025 F-650/F-750 vehicles built on or before 22-Jul-2024 and equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P203B, P206B, and/or P2201:92 stored in the powertrain control module (PCM). This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool.

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 26-22522026-09-12. 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 the software in the TCM (diesel only) and/or sticking valves in the main control valve body and/or damaged E clutch friction plates and E clutch steel plates.

SSM 549762026-07-07. Service bulletin. 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. 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.

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 25-25722025-12-01. Service bulletin. This article supersedes TSB 25-2322 to update the Service Procedure, Labor Operations and Parts List. Some of the vehicles listed in the Model statement above may exhibit an upper engine ticking or tapping noise at idle. Customers may also report experiencing rough engine performance, engine misfire, or a malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0301-P0308 in the powertrain control module (PCM). This may be due to camshaft and/or valve tappet having excess wear within the engine assembly.
