It's a new 8 speed called the 8L90E... still torque converter based. However, converter based autos have come a long way in the last few years. The latest stuff out there shifts as fast as the average DCT. My guess is the 8L90E will offer blistering performance in manual/race modes and change the way most think about an "automatic" transmission.

a dct (dual clutch trans) is not a auto. just as the paddles in a c6 auto dont make it a dct. dct is a manual trans which uses the computer, servos and solenoids to controll the clutch and shifting.

If it shifts gears without driver intervention, it is an automatic no matter what is inside the gearbox or how the engine is coupled to the gearbox..

I think there might be some confusion in terminology on this forum. A sequential manual trans uses paddles to shift but you cannot skip gears ie: 1-3. It uses a motorcycle transmission and needs no clutch but upshifts to top and back down again in something like .20 second! It is a manual transmission with no clutch. F-1 and BMW Ferrari etc use this method and most are built by XTRAC.
As to a DCT I think Honda started this tech but I don't know much about it.
The current shift-matching paddle is a component of this type of tranny and I have used this transmission for about 3 years now and it is far and away the best shifting method available for hard fast and precise driving. I would be the first to say it does not replace a standard auto transmission. It does not use any fluid coupling and is direct drive with the ability to easily change internal ratios.

I prefer to call it a an automated sequential manual gearbox and believe the corvette will eventually get one, but it may not be until the C8. Price and power being the current obstacle, ie the 2012+ Ford Focus utilizes one.

A sequential and a DCT are very different xmissions. Neither one will be utililzed in a Vette. See DCT thread.

Yes, they're different internally and the latter is a better/newer design, but essentially both do the same thing.

Missed that one, curious of your exact field of mechanical engineering?
