Ford Vehicles May Whine at Low Speeds

Some 2020 Ford F-150/Mustang/Ranger vehicles equipped with a 10R80 transmission and built on Oct. 21, 2019, and through Dec. 16, 2019, may exhibit a high-pitched whine noise coming from the transmission at low speeds during light acceleration or coasting. 

This may be due to the outer output shaft bearing. 

To correct the condition, follow the service manual procedure to replace the transmission inner output shaft bearing, fluid passage sleeve and outer output shaft bearing.
