Service bulletin SSM 49063

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 2017-2020 F-Super Duty vehicles equipped with a 6.7L diesel engine may exhibit an illuminated malfunction indicator lamp (MIL) and diagnostic trouble code (DTC) P20EE. The Powertrain Controls and Emissions Diagnosis (PC/ED) pinpoint test RD15 has been updated to perform a diesel particulate filter (DPF) manual regeneration with the appropriate Ford diagnostic scan tool twice along with performing a diesel particulate filter (DPF) parameter reset and drive cycle.

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 26-2088 v22026-10-05. Service bulletin. This bulletin supersedes 24-2249. Reason for update: update the claim quantity of the torque converter nuts, part number and claim quantity of the front support assembly bolt washers, and part number change of the fluid pan from the Parts List. Reissued 01-Oct-2026 - Added LC3Z-7G091-B to the part list
TSB 26-22162026-05-14. Service bulletin. This bulletin supersedes 25-2549. Reason for update: To add 2020 model year chassis cab vehicles. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0420 and/or P0430 stored in the powertrain control module (PCM). This may be due to the software in the PCM. This condition does not affect vehicle drivability or durability.
TSB 26-20882026-03-10. Service bulletin. This article supersedes TSB 24-2249 to update the claim quantity of the torque converter nuts, part number and claim quantity of the front support assembly bolt washers, and part number change of the fluid pan from the Parts List. Some of the vehicles listed in the Model statement above may exhibit a harsh reverse to drive engagements with no diagnostic trouble codes (DTC). This may be due to sticking valves in the main control valve body and/or damaged input shaft seals (F9), and the output shaft seals (F10).

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.
TSB 25-23572025-08-12. Service bulletin. This article supersedes TSB 23-2160 to update the parts list. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: * An illuminated powertrain malfunction (wrench) indicator with DTC P07F7 * Loss of 10th gear. The vehicle may also exhibit harsh engagements and poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit leaks.
TSB 25-23222025-07-24. Service bulletin. This article supersedes TSB 25-2200 to update the parts list to add the new camshaft and tappet service kit and add F-650/F-750. 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.
TSB 25-22622025-06-19. Service bulletin. This article supersedes TSB 23-2076 to update the powertrain control module (PCM) software level addressing the condition. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with cylinder injection pulse offset diagnostic trouble codes (DTC) P2B11, P2B13, P2B15, P2B17, P2B19, P2B1B, P2B1D, and/or P2B1F stored in the powertrain control module (PCM). The vehicle may also exhibit a slight running rough condition at idle. This may be due to incorrect learned values in the PCM from operating the vehicle at altitudes greater than 2500 feet (762 meters) above sea level. This condition does not affect vehicle drivability or durability.
