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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10250309-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10250309-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10250309","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2022,"year_to":2024,"match":"exact","vehicle_ids":["2022_ford_expedition","2023_ford_expedition","2024_ford_expedition"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2022,"year_to":2024,"match":"exact","vehicle_ids":["2022_lincoln_navigator","2023_lincoln_navigator","2024_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
