Official summary
This article supersedes TSB 23-2019 to update the model years affected, add an additional labor operation, and correct the part number called out in the Service Procedure. Some 2021-2024 Bronco vehicles equipped with a MT88 manual transmission may experience a rotational scraping noise while the transmission is in neutral, 1st or 2nd gear with the clutch pedal released and may be more noticeable in ambient temps below 10à °C (50à °F) and after a cold soak. This noise may diminish as the transmission warms up. This may be due to the 5th and 6th gear synchronizer rings.
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.
