Official summary
Some 2020-2021 F-Super Duty vehicles equipped with a 10R140 transmission may exhibit a ticking or scraping noise coming from the bellhousing. The noise may or may not go away while in PARK and/or NEUTRAL. This may be due to the torque converter studs contacting the flexplate inspection cover and/or internal torque converter damper spring contact. To correct the condition, inspect and adjust the flexplate inspection cover (gas engine only) and/or replace the torque converter (gas or diesel engine).
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.
