Official summary
14519 - Special Coverage. On some vehicles, the mechanical flag used by the automatic transmission shift assembly to display the selected gear may break off from the flag carrier. If a vehicle has this condition, the transmission shift assembly?s PRNDL display may improperly indicate the wrong gear or that no gear has been selected. Dealers are to install the service PRNDL indicator kit.
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.
