Special Service Message 51939 - 2017-2023 Various Vehicles – 10R60/10R80/10R80 MHT/10R100 Transmissions – Whine Noise From Bellhousing/Front Of Fluid Pan At Idle And/Or While Driving

Some 2017-2023 Ford and Lincoln vehicles equipped with a 10R60/10R80/10R80 MHT/10R100 transmission may exhibit a whine noise at idle and/or while driving. This may be identified as coming from the bellhousing and the front of the transmission fluid pan. The whine noise may become louder when the transmission is at operating temperature and may increase with engine revolutions per minute (RPM) in the park (P) position. A small amount of whine noise is considered to be characteristic of the 10R60/10R80/10R80 MHT/10R100 transmissions due to the offset gear drivetrain in the front support and has no effect on durability. Use the "Report a Vehicle Concern" link at the bottom of OASIS to submit a report if there is a customer concern of whine noise describing operating conditions and noise severity.

This type of operating characteristic noise should be listed in the vehicle’s owner manual (since it is considered normal by Ford).

The fix?

No fix, whine is normal. This appears to just being giving the techs an off ramp when dealing with customers that complain about the whine. Techs now have a proper place and procedure for documenting customer complaints regarding transmission whine.
