Service bulletin tsb18-2175

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.

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

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.
SSM 52476	2024-05-03. Service bulletin. All accessory stick-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated (wired) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System (DPES); dealership management can authorize users. The authorized user must go to FMCDealer.com > Parts and Service > Parts Product Line Information > Keys/Entry Devices > Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad.
SSM 52444	2024-04-29. Service bulletin. 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 52428	2024-04-29. Service bulletin. 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.
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.
SSM 52314	2024-03-20. Service bulletin. 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.
