Official summary
04627731A$ - Trans Vent Hose The upper end of the transmission vent hose terminates with an open elbow. There is no cap on the end of the vent hose. This is intentional. Some graphics in StarParts may show a vent hose including a cap, but this is incorrect. The actual production vent hose has an open elbow fitting, not a cap. The elbow should be pointing downwards in the vehicle.~
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.
