No manual mode perhaps? I'm not surpised at all - my ignorance of the latest greatest does happen. Pardon my title of "enthusiast" when I have not kept up on the latest Ford Fiesta However, to my credit, as soon as I heard about DCTs I knew they would eventually come in this form - no manual mode. Dual clutch still works but lacks some clarity. The most precise here would be automated dual clutch. And no that does not fully capture a DCT with manual modes.

I obviously believe that what is inside the unit is nearly as important as how many or where the operating levers are located. An automatic transmission even the AMG MCT with buttons or paddles as opposed to a lever and button on the transmission tunnel are automatic transmissions. The removal of the torque converter in the MCT for take offs does not change 95% of everything else inside the box, complex bands and hydraulics, planetary gears and a fluid pump to control the hydraulics.

It is the engineering AND the interface which define a trasmission.

"The key difference between a manual and an automatic transmission is that the manual transmission locks and unlocks different sets of gears to the output shaft to achieve the various gear ratios, while in an automatic transmission, the same set of gears produces all of the different gear ratios."
Not my words just another source and perspective.

Nope, replacing the human with a computer and hydraulics is not enough to change the name of the unit. It is the two clutches and essentially two manual transmissions in parallel that is the huge worthwhile innovation of a DCT to call it something different. DCT or automated manual.
