Official summary
Some 2021-2025 F-150 vehicles may exhibit a stuck in park condition with no diagnostic trouble codes (DTCs). This may be due to connector C211 pin push out on circuit CCB61 or an open on circuit CCB61 between the antilock brake system (ABS) module and the body control module (BCM). Workshop Manual (WSM), Section 307-05 Automatic Transmission External Controls > Diagnosis and Testing > External Controls - Pinpoint Test for "Stuck In Park" has been updated with improved diagnostics. Refer to revised WSM sections for normal diagnosis.
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.
