TSB 24-22492024-09-02. Service bulletin. POWER TRAIN. This article supersedes TSB 22-2087 to update the Part List. Some 2020-2022 F-Super Duty vehicles equipped with a 10R140 automatic transmission may exhibit harsh reverse to drive engagements without diagnostic trouble codes (DTCs). This may be due to sticking valves in the main control valve body or suspect input shaft seals (F9) and the output shaft seals (F10). To correct the condition, follow the Service Procedure steps to perform the transmission accelerated main control break-in routine for the E and F clutches and if necessary, replace the input shaft seals (F9) and the output shaft seals (F10).
SSM 525952024-06-10. Service bulletin. POWER TRAIN. When replacing the E clutch hub (7P211) on 2020-2024 F-Super Duty and 2024-2025 F-650/F-750 vehicles equipped with a 10R140 transmission, a new washer (7482) has been added and must be installed with the new updated E clutch hub. Refer to the Workshop Manual (WSM), Section 307-01B for proper installation of the washer. Refer to the parts catalog for the appropriate part numbers for the E clutch hub and the washer.
SSM 525482024-05-23. Service bulletin. POWER TRAIN. 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 523142024-03-20. Service bulletin. POWER TRAIN. 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.
SSM 516912023-06-16. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; POWER TRAIN. 2011-2023 F-Super Duty and 2016-2024 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C (80°F) and may increase to 1200 RPM at -40 °C (-40°F). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
SSM 516482023-05-31. Service bulletin. POWER TRAIN; EQUIPMENT. Some 2020-2022 F-Super Duty vehicles equipped with a 6.7L engine may experience a lack of power due to snow packing of the engine air cleaner when operating in extremely snowy conditions. This may also be due to ice forming in the air intake while operating in temperatures below -22°F (-30°C). Diagnostic trouble code (DTC) P1548 may be present in the powertrain control module (PCM). To supplement heavy snow environment pre-filter service kit (service part LC3Z-9K635-AA), a front grill cover (service part NC3Z-19A413-A) is now available for service but is not a warrantable item. It is recommended that the front grill cover be removed at temperatures greater than 10°F (-12°C) and reinstall in subsequent winter seasons in order to maintain optimal vehicle performance.
TSB 23-21602023-05-29. Service bulletin. POWER TRAIN. Some 2020 F-Super Duty vehicles equipped with a 6.2L or 7.3L engine and a 10R140 transmission may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P07F7 stored in the powertrain control module (PCM) and a loss of 10th gear. The vehicle may also exhibit harsh engagements and poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit leaks. To correct the condition, follow the Service Procedure to replace the CDF clutch cylinder.
SSM 507422022-05-14. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. Some 2020-2022 F-Super Duty vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0073 for the ambient air temperature sensor stored in the powertrain control (PCM). When performing pinpoint test BF in Workshop Manual (WSM), Section 413-01, the ambient air temperature sensor/outside air temperature display reset procedure has been added to the Ford Diagnostic Repair System (FDRS) diagnostic scan tool. Depending on how the vehicle is equipped, run the FCIM or HVAC. Reset the Outside Air Temperature Sensor Learned Values application. Clear DTCs and retest after performing the reset procedure.
SSM 506362022-03-29. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; ENGINE AND ENGINE COOLING; EQUIPMENT. 2011-2022 F-Super Duty and 2016-2023 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C (80°F) and may increase to 1200 RPM at -40 °C (-40°F). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
SSM 494832021-02-04. Service bulletin. POWER TRAIN. Some 2017-2021 F-Super Duty and 2016-2021 F650-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2021 F-150 with 3.0L diesel engines may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P206C in the powertrain control module (PCM). Review of repair data supports that P206C is often the result of incorrect diesel exhaust fluid (DEF) concentration. Per Powertrain Control/Emissions Diagnosis (PC/ED) Pinpoint Test (PPT) RJ, a DEF concentration reading below 28% will set P206C and cause vehicle derate. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts. Low concentration of DEF is not a warrantable condition.
SSM 494392021-02-04. Service bulletin. POWER TRAIN; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY. Some 2020-2021 F-Super Duty vehicles with 6.7L and 10R140 powertrain may exhibit an illuminated powertrain malfunction indicator (wrench) lamp with only DTC P07F6 stored in the transmission control module (TCM). The vehicle may also exhibit harsh engagements, poor shift quality and/or loss of 9th gear as a result of the DTC being set. If no additional DTCs or symptoms are present, clear keep alive memory and transmission adaptive tables with the appropriate Ford diagnostic scan tool, and perform an adaptive learning drive cycle. Transmission replacement is not necessary. Inform customers that a further improved calibration will be available in early March 2021. Let the customer know they can continue to drive the vehicle after performing this SSM, and schedule a service appointment for early March 2021. Monitor OASIS for updates.
