This article supersedes TSB 20-2107 to update the Part List. 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.
