Yes. The DCT will not let you past redline. The fuel will cutoff if you do, and there is no money shift.

S is Sequential modeUse the shift paddles or the selector lever to up‐shift or downshift without letting off the gas.▷ Shortly before falling below a gear-dependentminimum speed, the transmission is automat‐ically downshifted.▷ Upshifting or downshifting is done only if therpm and vehicle speed are appropriate.E.g., there is no downshifting if the enginespeed is too high.▷ Kickdown: the lowest possible gear is se‐lected by simultaneously operating the kick‐down and the left shift paddle or selectorlever.▷ It is also possible to start out in 2nd gear, forinstance on icy roads

Or on track, I've gone 5-3 while braking into a corner and end up in 2nd. Neither is a problem but you have to be ready for the high RPMs, quick throttle and need for an upshift.

Remember you don't control a DCT box, the computer does. When you flick a paddle you are just kindly asking the computer if it will change gear for you please, after it's done about a 1000 calculations and checks first. If you want to money shift or trash your gears the only way is to get a manual! Last edited by doughboy; 02-25-2021 at 03:20 PM.. |

PS: They could do a "manual transmission" that merely uses the gear shift and clutch to tell the computer what you want to do and the DCT takes over. Would purists go for that?

Wouldn't be a manual then? The whole point of a manual is that it's a bit slow and clunky and hard work. Takes practice and effort to get it just right over years of use. Put a computer in there and the whole point is lost. Oops. No auto\manual debates Last edited by doughboy; 02-26-2021 at 03:26 PM.. |

My experience on the track with the DTC is it is the ability to do the over-rev downshift is pretty bullet proof. I occasionally lose track of what gear I am in entering a corner and if the potential rpm's are too high while trying to downshift it won't shift. I try to keep rpm's in the 5000-7000 range but, like I said, a brain fart sometimes has me trying to downshift when I should not. I never got the hang of heel-toe shifting and this DCT is so very helpful in shifting down or up when you want it and won't let you when you shouldn't. Compared to my previous track car, a 2008 Z4 3.0si with a manual transmission, it is almost like cheating. I really like this transmission for the track. Not so much, yet, for autocross though.
