Despite this one time, I love the M-DCT and would still take it over manual anyday.
Ding. Ding. Ding. We have a winner.
This stalling out, as the OP calls it, is almost certainly running up against the rev limiter and is operator error, not a transmission issue. Someone please correct me if I am wrong.
I think we can write this thread off.
