SSM 479762019-06-07. Service bulletin. POWER TRAIN. On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop Manual (WSM), Section 307-01.
TSB19-21602019-06-05. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2017-2019 F-Super Duty vehicles equipped with a 6.7L engine built on or before 9-Jan-2019 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P2074, P0401, P0402 and/or P0170. This may be due to various strategies within the powertrain control module (PCM) software. To resolve this condition, follow the Service Procedure steps to reprogram the PCM and perform a mass air flow (MAF) parameter reset. Follow the service procedure steps to correct the condition.
SSM 479032019-05-07. Service bulletin. POWER TRAIN. SSM 47903 - 2018-2019 F-150/F-Super Duty/Transit - Rear Axle Pinion Seal Fluid Leak/Seepage Some 2018-2019 F-150, F-Super Duty, and Transit vehicles may exhibit the appearance of a fluid leak or seepage from the rear axle pinion seal. The appearance of a fluid leak or seepage on a vehicle with less than 500 miles or less than 3 months in service may not be due to a failed rear axle pinion seal. The appearance of fluid around the seal may be from the axle assembly being shipped to the vehicle assembly plant with the pinion facing down. To determine if a leak is present, clean the seal area of any residual lubricant and visually inspect the pinion seal for leaks or damage in the seal contact area or dust slinger on the pinion flange dust shield. If no concerns are found, run the vehicle on a hoist in DRIVE at idle speeds for 10 minutes to allow the fluid to circulate and recheck for signs of leakage.
SSM 478232019-04-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ENGINE. Various 2013-2019 vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P264F after powertrain control module (PCM) replacement. This DTC indicates that the engine serial number (ESN) must be programmed into the PCM. The ESN is located on PTS> OASIS> Features> Engine Serial Number. Once the ESN is obtained from the historical vehicle bill of materials (HvBOM), it can be programmed into the PCM using the appropriate Ford diagnostic scan tool. Navigate to the toolbox tab> powertrain menu> Service Functions> ESN.
TSB 19-20532019-04-02. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN. Some 2017-2019 F-Super Duty chassis cab/dual rear wheel (DRW) pickup vehicles and 2016- 2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an oil consumption concern in applications where the engine is idled for extended periods of time. This may be due to high crankcase pressure as a result of the crankcase ventilation filter element becoming restricted. To resolve the concern, replace the crankcase vent oil separator. The new crankcase vent oil separator appears different from the old crankcase vent oil separator as it no longer includes a serviceable filter element.
SSM 478232019-04-01. Service bulletin. POWER TRAIN. Various 2013-2019 vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P264F after powertrain control module (PCM) replacement.
