Service bulletin TSB 22-2245

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

This article supersedes TSB 21-2021 to update the part list Some 2019-2020 Ranger vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0420 stored in the powertrain control module (PCM). This may be due to various software parameters within the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM and replace the catalytic converter.

Other bulletins for the same vehicles and component
TSB 26-2359	2026-08-10. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0420 stored in the powertrain control module (PCM). This may be due to the software in the PCM.
SSM 54592	2026-02-27. 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.
SSM 54366	2025-11-19. Service bulletin. Some 2015-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. Pinpoint test HK in the Powertrain Control and Emissions Diagnosis (PC/ED) or in Section 303-14 of the Workshop Manual (WSM) has been updated to address this concern.
SSM 52548	2024-05-23. Service bulletin. 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.
TSB 24-2101	2024-04-04. Service bulletin. This article supersedes TSB 24-2046 to update the Service Procedure LTIS statement. Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, 2019-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift, an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) that are stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder (7H351) sleeve.
TSB 24-2046	2024-03-07. Service bulletin. This article supersedes TSB 23-2350 to update the Issue statement and the Service Procedure. Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, 2019-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift, an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder (7H351) sleeve.
TSB 23-2350	2023-11-22. Service bulletin. Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, 2019-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift, an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes This may be due to the software in the powertrain control module (PCM) or transmission control module (TCM), the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder (7H351) sleeve. To correct the condition, follow the Service Procedure to identify and correct the condition.
SSM 51939	2023-10-06. Service bulletin. Some 2017-2023 Ford and Lincoln vehicles equipped with a 10R60/10R80/10R80 MHT/10R100 transmission may exhibit a whine noise at idle and/or while driving. This may be identified as coming from the bellhousing and the front of the transmission fluid pan. The whine noise may become louder when the transmission is at operating temperature and may increase with engine revolutions per minute (RPM) in the park (P) position. A small amount of whine noise is considered to be characteristic of the 10R60/10R80/10R80 MHT/10R100 transmissions due to the offset gear drivetrain in the front support and has no effect on durability. Use the Report a Vehicle Concern link at the bottom of OASIS to submit a report if there is a customer concern of whine noise describing operating conditions and noise severity.
TSB 23-2251	2023-09-01. Service bulletin. Some 2019-2023 Ranger (non-Tremor) vehicles may exhibit a shudder/vibration when accelerating. This may be due to an excessive rear axle pinion angle (rear wheel drive (RWD) vehicles) or the pinion and driveshaft assemblies (four-wheel drive (4WD) non-Tremor vehicles). To correct the condition, follow the Service Procedure steps to adjust the rear axle pinion angle on 4x2 vehicles or replace the rear axle pinion and driveshaft on 4x4 non-Tremor vehicles.
TSB 23-2250	2023-08-30. Service bulletin. This article supersedes TSB 22-2428 and 23-2176 to update the Issue, Action and Service Procedure.
