I know the VW DSG has been in use for a few years now, how are they holding up? Is there a real advantage with fuel economy or power?

The burgeoning interest in dual clutch gearboxes should be big business for Getrag over the next few years. Because a dual clutch transmission (DCT) combines the greater efficiency of a manual with full automatic shift capability they are being installed in more vehicles all the time. The first widespread use of DCTs was on Volkswagen and Audi models in the last few years with their Borg-Warner-built DSG units.

For 2008, Volvo is adding a DCT to the S40 and V50 while Ford is also adding one to the Focus equipped with a new 2.0L turbodiesel. Chrysler is also installing a DCT in European-spec models of the new Dodge Journey CUV. By 2010 Getrag expects to sell 500,000 DCTs a year growing to 2 million by 2014. That doesn't include the 700,000 units that will come from the Chrysler-Getrag joint venture starting in 2009.

DSG is like an auto but gets rid of the torque converter. It also looks nothing like an auto's planetary gearset.

It's heavier, is more complex than a manual, and requires special fluid. Pass. The CVT gives better power and fuel economy since it's a variable ratio trans. the trans that uses a belt instead of gears)

Get used to it, B<W, Audi, and VW are all pushing this technology. Nissan is pushing CVT. I'm sure manuals will still be around for a while, but the autos will be changed a lot.

And now Mitsubishi has come out with their own dual clutch DSG type transmission. It'll be on the mitsubishi evolution. The nissan skyline is also comig out with a DSG type transmission as the only initial option in Japan. Seems that it gives better performance and faster shifting.

The porsche 911 turbo is also faster with an auto than their 6 speed.

I guess I am just used to shifting with a clutch pedal and shiter. Makes me feel more involved.

It's in the new skyline, the only choice of transmission for now.

Well I've been doing more research on this, the DSG look pretty durable. It looks like the flywheels have had some issues because they come apart or loose from a dual layer tho.
