Official summary
Some 2020 Explorer/Aviator vehicles built on or before 19-May-2020 and equipped with a 10R60 automatic transmission may exhibit a harsh 7-6 gear downshift. This may be caused by the A clutch piston return spring snap ring becoming dislodged. To correct the condition, follow the Service Procedure steps to replace the front support and A clutch assemblies.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
