Some 2018 Mustang vehicles equipped with a 10R80 transmission may exhibit a concern of no upshift past second gear or not achieving third gear ratio with DTCs P0757 and P2701. This concern may be caused by a damaged one-way clutch. To resolve this condition, replace the complete front support assembly (7A130) which includes the one-way clutch as well as any other parts that are found to be damaged.
