    I’m not sure what you mean. I didn’t read that entire article, but I see it called an automatic at least twice.

    Other than the badge on its hood, the dual-clutch automatic transmission in the 760-horsepower 2020 Ford Mustang Shelby GT500”

    A dual-clutch automatic has electronic controls and two clutches, so it can adjust the connection more quickly and precisely than a human”

    The title of the article uses "dual clutch transmission."

    "Automatic" is a generic term that includes the well known hydraulic transmission but also CVT and various semi-automatic as well as the DCT. Simply calling it an automatic does not convey the marvelous engineering that makes it a choice for many high performance cars. We all have our favorite motorcycle but we don't consider it equivalent to a Honda 50 simply because they're both motorcycles.

    What is this discussion about? I'm lost.
    If you have enough skills and experience and access to the right equipment (e.g. 3D printer), you can modify the right and left handlebar switch assembly, i.e. eliminate AT/MT switch (leave it on AT mode), eliminate D-S mode switching, leave N-D mode and eliminate +/- shifting.
    And here you have it - a fully automatic motorcycle. You can sell it as such to a complete layman who knows nothing (because doesn't have to know) how the motorcycle is built and why it is automatic. And it only matters: if it quacks like a duck, then ...
    Of course mechanical engineers may argue whether DCT is a fully automatic transmission, like CVT or a traditional automatic full mechanical transmission, or it is a semi-automatic, from a mechanical point of view, because the signal about the work of clutches and gears comes from an external source, i.e. PCM. But does a regular user care about this?
    Honda certainly loves this confusion. First it's automatic, but if you don't like DCT in D mode, you can switch to S mode or use manual gear shifting... because it is semi-automatic.
    And for them this duality works perfectly - it stops complains and makes a fan base more confident.
    Ford was not so lucky when PowerShift car owners lost confidence in their products. Because how can you explain that the transmission suddenly shifts to neutral or stays in gear. (Because of a bad battery?)
    The main reason for supercars to use DCT is very fast gear shifting.

    There are four types of transmissions: 1) manual, 2) automatic, 3) CVT and 4) semi-automatic and dual clutch. Therefore, a DCT is a type of semi-automatic transmission. It's a manual transmission fitted with two clutches.

    Wait, we're all correct. This debate is not about what it is, it's about what category you want to put it in. Categories can be defined in general terms or more specific terms.

    Why do you want to break the door already open? This classification has already been made. E.g. Wikipedia has very apt DCT definition and description.

    Good point. Although the DCT is new to many, a review of Wikipedia finds a long history and application in a lot of vehicles. It seems Honda is the only motorcycle manufacturer so far but that probably will charge soon. It's new to most people so we don't have a comfortably simple niche to put it in yet.
