This may be due to the torque converter studs contacting the engine-to-transmission spacer plate (separator plate). To correct this condition, remove the transmission and flexplate and inspect the engine-to-transmission spacer plate and torque converter studs for wear/damage. If wear/damage is found, replace engine-to-transmission spacer plate. Refer to Workshop Manual (WSM) Section 303-01 Engine - 3.5L EcoBoost (BM), Removal and Installation, Crankshaft Rear Seal. When reinstalling the starter motor, be sure the starter is flush with the engine-to-transmission spacer plate prior to tightening the studbolts. Failure to do so may result in damaging newly installed engine-to-transmission spacer plate.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10250847-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10250847-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10250847","components":[{"id":"engine","name":"Engine","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2023,"year_to":2024,"match":"exact","vehicle_ids":["2023_ford_expedition","2024_ford_expedition"]},{"make":"FORD","model":"F-150","year_from":2021,"year_to":2023,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150","2023_ford_f-150"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2023,"year_to":2024,"match":"exact","vehicle_ids":["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.
