Summary

Some 2020-2022 F-Super Duty vehicles equipped with a 10R140 automatic transmission may exhibit harsh reverse to drive engagements without diagnostic trouble codes (DTCs). This may be due to sticking valves in the main control valve body or suspect input shaft seals (F9) and the output shaft seals (F10). To correct the condition, follow the Service Procedure steps to perform the transmission accelerated main control break-in routine for the E and F clutches and/or replace the input shaft seals (F9) and the output shaft seals (F10).

Owners of these vehicles have filed 213 complaints in the transmission category.
