If I'm in auto and cruising around 5th, 6th, 7th gear - then floor it.... the car will downshift, the clutch won't engage fast enough, rev up (burn up?) and go into limp mode with a transmission overheating error. I confirmed a couple others with the same issue so it's not just mine.

In manual mode, it's not as bad but still have to wait when down shifting if it's more than 1 gear. Maybe a second or two for it to clearly engage. I don't drive it much so I'm not an expert on the intricacy of it, but it's certainly not ideal.

I'd love it if others here have a DCT and supercharger and can chime in. Maybe I need a different DCT tune or something, no idea. But to be clear, when going up in manual mode it's rock solid, going down not bad but if I drop the gears several gears too fast, and get on it too quickly I'll have issues.
