Official summary
This bulletin supersedes 25-2383. Reason for update: to add 2023-2026 F-150 2.7L vehicles. Some of the vehicles listed in the Model Statement may exhibit a vibration/shudder felt during light throttle tip in at highway speeds (8,9,10 gear) with no diagnostic trouble codes (DTC) present. This may be due to various software parameters in the powertrain control module (PCM).
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
