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 10ðC (50ðF) 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.
