Official summary
Service bulletin - The 8-Speed dual-clutch transmission (DCT) has a bump or hard shift when coming to a stop, usually on the downshift from 2nd to 1st. This symptom is intermittent and may be difficult to duplicate. The PCM settings are not properly breaking-in the odd and even clutches.
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.
