| TSB 26-2375 v2 | 2026-10-13. Service bulletin. NOTE: This bulletin has been updated, refer to the change log at the bottom for details. Issue: Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: • Poor shift quality • Illuminated powertrain malfunction (wrench) indicator with DTCs P2704 and P0771 stored in the PCM / TCM . This may be due to a calibration in the TCM and/or wear between the input shaft and the E clutch hub causing theinput shaft O-rings to become damaged resulting in an open E clutch circuit. Action: For vehicles that meet all of the criteria in the Issue and Model statements, follow the Service Procedure toreprogram the PCM / TCM and/or replace the E clutch hub and input shaft O-rings |

| SSM 55228 | 2026-10-12. Service bulletin. Some 2020-2026 Aviator/Explorer/F-150/Bronco/Ranger vehicles equipped with a 2.7L or 3.0L (non-diesel) engine may need the front engine cover removed and reinstalled for various reasons. The Workshop Manual (WSM), Section 303-01 Engine > Removal and Installation > Engine Front Cover service procedure has been updated to include a new essential special service tool (ESST) guide pin alignment tool (303-1790) that is used to align the engine front cover to the engine block, preventing the O-ring seal on the engine oil galley feed tube from getting damaged during installation. |
| SSM 55221 | 2026-10-12. Service bulletin. For 20222026 vehicles equipped with a 8F35 transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, 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, and/or D>R) should be noted in the warranty claim. 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 55218 | 2026-10-06. 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. |
| SSM 55217 | 2026-10-06. Service bulletin. Some 2020-2024 Explorer/Aviator vehicles equipped with 3.0L EcoBoost/hybrid engine may exhibit blue or black exhaust smoke on startup for the first 5 minutes after an overnight cold soak with no illuminated malfunction indicator lamp (MIL) or powertrain diagnostic trouble codes (DTCs) present. This may be due to engine oil breaching the dynamic oil seals separating the bearing core from the turbine housing in the left side turbocharger assembly. There is a new, updated left side turbocharger oil supply tube equipped with an internal check valve to prevent the engine oil from entering turbine housing after the engine is off. Replace the existing left side turbocharger oil supply tube with the updated service part that includes the check valve (service part# L1MZ-9T516-B) or latest level part. Refer to the Workshop Manual (WSM), Section 303-04 Fuel Charging and Controls - Turbocharger > Removal and Installation > Turbocharger Oil Supply Tube LH. For claiming, use causal part 9T516 and labor operation code 9440AL. |
| SSM 55211 | 2026-10-06. Over-the-air update. 2023-2026 Escape and 2025-2026 Bronco Sport vehicles equipped with a 1.5L EcoBoost engine may require removal of the turbocharger wastegate control actuator linkage for various reasons. The Workshop Manual (WSM), Section 303-04 Fuel Charging and Controls - Turbocharger - 1.5L EcoBoost > Removal and Installation > Wastegate Control Actuator Linkage service procedure has been added. In addition, the wastegate control actuator linkage rod with retaining clips (6K682) and actuator linkage rubber boot seal (9E416) have been released as lower-level components to complete the repair without replacing the entire turbocharger wastegate control actuator assembly. |
| TSB 26-2088 v2 | 2026-10-05. 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 26-2428 | 2026-10-02. Service bulletin. This bulletin supersedes 25-2326. Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM). This may be due to the software in the PCM and/or the fuel tank isolation valve. |
| TSB 26-2428 | 2026-10-02. Service bulletin. This bulletin supersedes 25-2326. Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM).

| TSB 26-2341 v2 | 2026-10-01. Service bulletin. This bulletin supersedes 26-2171. Reasons for update: update the Parts list to add a note to clarify the application of the part numbers W520102-S442 and 4S4Z-3N324-AA "FWD Only". Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Shudder condition, most noticeable at speeds below 60 mph (100 km/h) No relevant diagnostic trouble codes (DTC) present Traceable shudder event with IDS/FDRS reading *(Figure 1)* This condition may be perceived/felt as an engine misfire. This may be due to a concern with the output planetary assembly. |
