Manufacturer summary
Original wording in English
Some 2020 F-Super Duty vehicles equipped with a 6.7L diesel engine and built on or before 18-Aug-2020 may exhibit an illuminated powertrain malfunction indicator (wrench) lamp with only diagnostic trouble code (DTC) P07F6 stored in the transmission control module (TCM). This DTC may be accompanied by harsh engagements, a poor shift quality feel and/or loss of 9th gear as a result of the DTC being set. If no additional codes or symptoms are present, clear the DTC with the appropriate Ford diagnostic scan tool and schedule a follow-up appointment for service mid-September. Inform the customer that engineering is working to implement a solution and advise the customer that they can continue to drive the vehicle. Once available, contact the customer and confirm a service appointment. Monitor OASIS for updates.
NHTSA manufacturer communications ↗Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
