Service bulletin TSB 19-2049

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 2019 Mustang and F-150 vehicles built on or before 8-Jan-2019 and equipped with a 5.0L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P1289 and/or P017D stored in the powertrain control module (PCM). This may be due to cylinder head temperature (CHT) sensor. To resolve the condition, replace the CHT sensor.

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.
TSB 25-2475	2025-11-04. Service bulletin. This bulletin supersedes TSB 25-2301. Reason for update: update the Part List Description. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh engagement * Delayed engagement * Harsh shift * Delayed shift * 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 axial movement of the CDF clutch cylinder (7H351) sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect and replace other transmission components and flush transmission fluid cooler only as necessary as needed to ensure proper function. Add a new line to the repair order to document any additional

TSB 24-2184	2024-06-12. Service bulletin. This article supersedes TSB 24-2115 to update the Service Procedure. Some 2018-2020 F-150 vehicles equipped with a 2.7L EcoBoost may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0420 and/or P0430 stored in the powertrain control module (PCM). This may be due to calibration and controls sensitivity. To correct the condition, follow the Service Procedure to perform the catalyst stabilization drive cycle.
SSM 52586	2024-06-10. Service bulletin. Some 2018-2023 Mustang vehicles equipped with a 5.0L engine and a 10R80 transmission may exhibit a buck/jerk sensation that may be perceived as an engine misfire during throttle tip-in between 35-45 mph (56-72 km/h) and with the transmission in 8th, 9th, or 10th gear. This buck/jerk sensation is a characteristic of the vehicle and can be compared to a like vehicle that is equipped with a similar powertrain (engine, transmission, and rear end gear ratio) driven in the same manner. A diagnostic trouble code (DTC) will not set because of this condition. If no DTC is set, inform the customer that the vehicle is operating as designed. If a misfire DTC is present, the DTC should be diagnosed first following the correct diagnostic procedure outlined in the Workshop Manual, Section 303-07B.
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.
