Ford technical service bulletin SSM 50261 for 2020-2021 Ford F-250 SD, 2020-2021 Ford F-350 SD and 2020-2021 Ford F-550 SD and others.

Bulletin number: SSM 50261
Component: Equipment: other: owners/service/other manual
Summary: Some 2021-2022 F-Super Duty vehicles may exhibit harsh or delayed engagement/shift concerns. Most concerns may be addressed with the PCM/TCM Transmission Accelerated Main Control Break In Routine. Refer to Workshop Manual (WSM), Section 307-01, DTC Chart and/or Diagnosis By Symptom to identify the clutch(s) to be cycled. This routine cycles the shift solenoids and clutch control valves to remove contamination that may be sticking the valves and must be performed along with an adaptive learning drive cycle before attempting internal service. Although this routine was originally developed for low mileage vehicles, it has proven effective for resolving many shift and engagement symptoms across the life of the vehicle. For claiming, use causal part 7A100 and applicable labor operations in Section 7 of the Service Labor Time Standards Manual.
