Summary

Some 2022 F-Super Duty vehicles equipped with a 6.7L diesel engine and a 10R140 automatic transmission may exhibit harsh 3-2 and/or 2-1 downshifts when coming to a stop in tow/haul mode or when using engine brake mode. Because this is related to a software issue, replacement of the transmission or other components will not resolve this condition and engineering is currently working on a software update which is expected to be available by the end of June 2022. In the interim Perform TSB 22-2015, steps 10-15 only, and evaluate if the concern is resolved. If the concern is still present, let the customer know they can continue to drive the vehicle and schedule a follow-up appointment for June 2022. Monitor OASIS for updates and confirm that the service appointment is going forward once the repair becomes available.

Owners of these vehicles have filed 39 complaints in the transmission category.
