Official summary
In affected vehicles, the transmission torque converter may overheat in certain driving conditions. If the torque converter overheats it can lead to adverse NVH, rough idle, and low performance concerns. Ultimately this will require internal transmission repairs to resolve the concern. Ford Motor Company has developed and update to the Powertrain Control Module software that helps protect the transmission torque converter from overheating when exposed to certain driving styles.

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.
