- Summary
- 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.
