Manufacturer summary

Original wording in English

Some 2020-2021 Mustang GT500 vehicles may experience erratic and harsh shifting at highway speeds and/or perceived lack of power when accelerating from a stop, with a powertrain malfunction (wrench) indicator and diagnostic trouble codes (DTCs) P1601 and/or P061A stored in the powertrain control module (PCM) while using SelectShift. This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
