## Other bulletins for the same vehicles and component

- [SSM 55072](/bulletins/11036337.md), 2026-08-25, Service bulletin: POWER TRAIN; ELECTRICAL SYSTEM; VEHICLE SPEED CONTROL. Some 2025\-2026 Mustang vehicles equipped with a 5.0L or 2.3L engine and built on 15\-Aug\-2025 and through 01\-Dec\-2025 may exhibit various drivability symptoms and/or have diagnostic trouble codes \(DTC\) stored in the powertrain control module \(PCM\) related to throttle/pedal position circuits. This may be caused by a spread terminal at the PCM connector. Inspect for loose fitting terminals at C1551B for 2.3L vehicles, and C175B on 5.0L vehicles. Refer to the appropriate Wiring Diagram Cells for circuit identification and wiring repair information. Wire terminal repair kit part DU2Z\-14474\-CA is recommended for this repair. Refer to Wiring Diagram, Cell 005 for repair procedures. For claiming, use causal part 14290 and labor operations 12651D, 12651D45 and 12651D45WR.
- [TSB 26\-2263](/bulletins/11033575.md), 2026-06-05, Service bulletin: POWER TRAIN. 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 \(OWC\).
- [TSB 26\-2210](/bulletins/11033573.md), 2026-06-05, Service bulletin: POWER TRAIN; ENGINE. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: \* Engine misfire condition \* Illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTC\) P0301, P0302, P0303, and/or P0304 stored in the powertrain control module \(PCM\)
- [SSM 54719](/bulletins/11031262.md), 2026-04-10, 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 54674](/bulletins/11030791.md), 2026-04-06, 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.
- [ECG2\-25.2.8.5 Mustang](/bulletins/11030366.md), 2026-03-31, Over\-the\-air update: UNKNOWN OR OTHER; ELECTRICAL SYSTEM; POWER TRAIN. "26C10 Recall remedy \-Addresses instances where the trailer lights and trailer brakes may not function"
- [TSB 26\-2112](/bulletins/11030178.md), 2026-03-23, Service bulletin: FUEL/PROPULSION SYSTEM; UNKNOWN OR OTHER; POWER TRAIN. This bulletin supersedes TSB 26\-2059. Reason For Update: To add missing labor operations. 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 \(OWC\).
- [TSB 25\-2587](/bulletins/11030177.md), 2026-03-23, Service campaign: POWER TRAIN; UNKNOWN OR OTHER. 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\-2059](/bulletins/11029552.md), 2026-03-04, 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 54593](/bulletins/11029082.md), 2026-02-27, 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.
