The stock DCT does not have as much SCHs on ANY of the model years except 2018.
Therefore I would assume that the stock 6MTs having SCH are money shifts, and the higher odds of SCHs happening are tune related.
AGAIN, I know this is a small sample of being reported, but it is an easy analysis to run. IF we can get more votes and push people to answer these questions more often we can find a better correlation. All I see is that tunes are primary reasons for REPORTED failures.

What I would find even more interesting is what % of ALL SCH (regardless of tune/trans) caused piston/valve contact VS. those which only required hub replacement.
Perhaps those that voted can tell us.
