Official summary
Some 2020 F-Super Duty vehicles equipped with a 10R140 automatic transmission and built on or before 21-Sep-2020 may exhibit a lack of power with an illuminated malfunction indicator lamp (MIL) and/or wrench lamp with diagnostic trouble codes (DTCs) P0715, P0716, P0717 and or P07C0 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to the turbine shaft speed (TSS) sensor. To correct the condition, follow the Service Procedure to replace the TSS sensor.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
