Summary

Some 2021 F-150/Explorer/Aviator/Police Interceptor Utility vehicles, excluding hybrid, with 5,000 miles (8,000 km) or less may exhibit harsh or delayed engagement/shift concerns with or without transmission diagnostic trouble codes (DTC) in the powertrain control module (PCM). Most concerns at low mileage may be addressed with the accelerated main control break-in routine. Refer to Workshop Manual (WSM) Section 307-01 Diagnosis and Testing, 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 before attempting internal service. For claiming, use causal part 7A100 and applicable labor operations in Section 7 of the Service Labor Time Standards (SLTS) Manual.

Owners of these vehicles have filed 455 complaints in the transmission category.
