Official summary
Transmission warning may appear in instrument cluster. After ignition cycle, the warning message is no longer present. The fault occurs with ATF temperature below 60o C.

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.
