Some 2021-2022 Bronco vehicles equipped with a MT88 manual transmission may experience a rotational scraping noise in ambient temps below 10C (50F) and after a cold soak with the transmission in neutral, 1st and/or 2nd gear and clutch engaged. The noise may go away as the transmission warms up. This may be due to the 5th and 6th gear synchronizer rings. To correct the condition, follow the Service Procedure to replace the 5th and 6th gear synchronizer rings.
