Official summary
This article supersedes TSB 23-2219 to update the Parts List. Some 2021-2023 Bronco vehicles may exhibit no 3rd gear engagement and/or a grinding noise going into 3rd and/or 4th gear. This may be due to the transmission shifting system and clutch interaction such as a lack of full clutch disengagement during shifts and/or placing weight upon the gear shift lever while driving. To correct this condition, follow the Service Procedure to replace the 3rd and/or 4th gears and/or synchronizers as needed.
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.
