Summary

Some 2020-2025 F-Super Duty vehicles equipped with a 10R140 automatic transmission may exhibit a delayed engagement into drive and/or reverse on initial start-up. The condition may occur at times after sitting overnight or for a couple of days. This may be due to the transmission fluid draining back from the torque converter. This is a normal characteristic of the 10R140 transmission and has no effect on durability, do not attempt to repair. Advise the customer to allow more time after first engine start-up and before shifting into gear allowing time for the torque converter to refill.

Owners of these vehicles have filed 243 complaints in the transmission category.
