What's important is the distinction in the discussion. The lines get blurred too much for the casual reader when you refer to a DCT automatic and torque converter based automatic transmission as essentially the same. They provide the same function which is to move forward and backward, however they do so in a different manner.Not to be a Smart *** but people keep correcting me by saying "you mean DCT" when I refer to the transmission as an automatic. There is no clutch pedal and you just put it in D and go, how is that not an automatic transmission regardless of the internal technology?
The standardized definition for "automatic transmission" has long ago defaulted to a torque converter based design, primarily because those transmissions have been in the overwhelming majority of automobiles. And that's not an understatement. Practically every "automatic transmission" car with the exception of a few models, have been the same design.
The first smart offering had an self-shifting single clutch manual, and the latest gas versions came with a self-shifting dual clutch manual which provides faster shifting and performance benefits. But it at its core is essentially the same design as a true manual transmission, at least based on the default definition within the current era of automobiles.
It's important to keep the distinctions in all discussions for those casual readers who are unaware of them. That way instead of panicking when they drive their smart when it feels "different" (from what they're used to), they can instead learn how to practice a driving technique that is more suitable for a single-clutch self-shifting manual, or dual-clutch self-shifting manual... (automatic!).
