Official summary
Some 2015-2020 Mustang Shelby GT350/GT350R vehicles may exhibit a hesitation or surge in the vehicle with no diagnostic trouble codes (DTCs) present. This may be accompanied by an inoperative cruise control system. This may be due to a transmission output shaft flange nut that has come loose, allowing the output shaft tone ring to move in relation to the output shaft causing an erroneous signal. To resolve the condition, follow the Service Procedure steps to replace the output shaft flange nut.

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.
