SSM 50512

Some 2021 F-Super Duty vehicles equipped with the 10R140 transmission and built on 01-Jun-2021 and through 31-Jul-2021 may exhibit no forward or reverse engagement with 3 or more clutch stuck off diagnostic trouble codes (DTCs) at one time, DTCs - P0751, P0756, P0761, P0766, P0771, P2707, P0741, and/or P0868. This may be due to the fluid pump gasket delaminating. If the current accelerated main control break in procedure SSM does not address the concern, make sure that the fluid pump gasket is inspected when the main control is removed. If the gasket is damaged, then proceed with replacing the gasket and reinstalling the main control. If the gasket is not damaged, then continue with the main control inspection as directed by the appropriate SSM.
