"We’ve combined the best attributes of conventional automatic, continuously variable and dual clutch transmissions. The transmission locks up to couple directly with the engine over a far wider range than other automatics. This delivers a significant improvement in fuel economy and a more direct, manual-like power delivery and driving feel. Shifts are quick, accurate and smooth across the six speeds."
So, as they mention, this transmission is unique. It does, however, not lock up in all conditions - it remains unlocked until you hit 8mph. It sounds like an interesting transmission, but this is not the "norm". All conventional automatic transmissions should be able to do this, although it results in very different wear patterns (brake rings and clutches in the transmission will see much greater wear). It is not quite as interesting as a dual shift transmission, though.
(Having looked at a picture of the transmission, ignore the "combined the best attributes of..." - it appears to be an entirely conventional automatic transmission with a very different operating profile.)
It locks up after 8 mph probably because if it locked up at any lower of a speed, the engine would be too close to stalling.
Also, the ZF 6HPxx (and newer) transmissions behave the same way. My 2011 335i will lock up in first gear (probably around 10 mph, but it depends on the load). This transmission has been used by BMW since at least 2006. A derivative of it is also used in the Ford Mustang now.
I should try a car with one of those transmissions, then. They sound quite interesting. While I have driven quite a lot of cars, I have never dealt with such a transmission, but it sounds both nice and efficient. How's the comfort tradeoff? I believe the lock-up was initially avoided due to comfort, as people liked the "gooey" transition between gears.
I'll keep that transmission in mind next time I go shopping.
