When Pulling Away From A Stop
Some 2020 F-350, F-450, and F-550 F-Super Duty chassis cab vehicles
equipped with a 6.7L diesel engine and 10R140 automatic transmission may
exhibit a delay/bump feel when pulling away from a stop. This may be due to
the neutral idle feature that automatically reduces the load on the engine when
the vehicle stops, and the gear selector is in DRIVE to reduce fuel consumption
and emissions. The transmission automatically resumes operation when the
brake is released. The neutral idle feature activates when the transmission is
sufficiently warmed, and the vehicle is on level grade. Do not attempt any
repairs for this condition. Refer to Owners Manual Transmission Section for
more information.
