Official summary
Some 2022-2023 Expedition/Navigator vehicles equipped with a 1 speed transfer case may exhibit a concern where the 4x4 setting reverts to 2H after a key cycle. This may be due to the transfer case control module (TCCM) software. To correct the condition, reprogram the TCCM using the latest version of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 7E453 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
Vehicles covered
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.
