SSM 547192026-04-10. Service bulletin. POWER TRAIN. 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
SSM 546742026-04-06. Service bulletin. POWER TRAIN. 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. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method.

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 26-20592026-03-04. Service bulletin. POWER TRAIN. 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 545932026-02-27. Service bulletin. ENGINE; POWER TRAIN; FUEL/PROPULSION SYSTEM. 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.
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 525482024-05-23. Service bulletin. POWER TRAIN. Various vehicles equiped with 10R80/10R80 MHT/10R100/10R140 transmissions may require replacement of the seal kits (7153) when internal repairs are being performed. These kits come with 4 wheel drive (4WD) seals and will no longer include the 2WD seals. When working on a 2WD vehicle, any 2WD seals must be ordered separately. Refer to the parts catalog for the proper 2WD seals required.
SSM 524442024-04-29. Service bulletin. POWER TRAIN. Some 2018-2024 Mustang vehicles built on and after 04-Dec-2017 may exhibit a ting, pop, clunk, or click noise from the rear wheel hub when accelerating, applying brakes, or when shifting between drive/reverse (torque reversals). This condition may be caused by stick/slip between the hub and halfshaft interface during the torque reversals creating the ting, pop, clunk, or click noise. To correct the condition, refer to the Workshop Manual (WSM) to replace the halfshaft and hub assembly of the suspected side(s).
SSM 524282024-04-29. Service bulletin. POWER TRAIN. Some 2018-2024 Mustang vehicles built on 04-Dec-2017 and through 01-Oct-2023 may exhibit a ting, pop, clunk, or click noise from the rear wheel hub when accelerating, applying brakes, or when shifting between drive/reverse (torque reversals). This condition may be caused by stick/slip between the hub and halfshaft interface during the torque reversals creating the ting, pop, clunk, or click noise. To correct the condition, refer to the Workshop Manual (WSM) to replace the halfshaft and hub assembly of the suspected side.
SSM 524192024-04-24. Service bulletin. POWER TRAIN. Some 2023-2024 Escape/Corsair vehicles equipped with a 1.5L or 2.0L EcoBoost engine, 2024 Mustang vehicles equipped with a 2.3L EcoBoost engine, and 2024 Nautilus vehicles may exhibit an engine misfire condition with diagnostic trouble codes (DTC) P0301, P0302, P0303 and/or P0304 set in the powertrain control module (PCM). If the codes are stored in the PCM, remove and inspect the condition of all the spark plugs. If any spark plugs appear to be damaged, use a borescope to inspect the condition of the cylinder walls. If the cylinder walls are scored/scraped/damaged, replace the long block engine assembly (6006) to resolve this condition. If the cylinder walls are not scored/scraped/damaged, replace the damaged spark plug(s) and advise the customer that engineering is investigating this issue. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.
TSB 24-20712024-04-03. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); POWER TRAIN; ELECTRICAL SYSTEM. Some 2024 Mustang vehicles equipped with a manual tranmission may exhibit an intermittent DTE reading that drops to 0 with the fuel level displaying near 25% capacity. This may be due to the software level of the powertrain control module (PCM). To correct this condition, perform the Service Procedure below to reprogram the PCM to the latest software level using the Ford Diagnosis and Repair System (FDRS).
SSM 523142024-03-20. Service bulletin. POWER TRAIN. During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in the timing gear breaking and engine damage. Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual (WSM) Section, 303-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.
