The DSG gear box was designed and is built by the US Borg-Warner company not VW as many think.
Corolla drivers don`t know what there missing yeer right like high service fee`s $120 pegged for three years on the Corolla and iffy electric`s on most euro-snob cars.

You Don’t have to justify driving a VW to me Reckless.
We are talking about the Chrysler trans which they even call an auto if you you would have looked. Get ya facts strait buddy!
Keep reading those reviews!

Fan Forced, the clutch in no way works as a torque converter, if you believe that you might buy a bridge I can get cheap. It doesn’t matter that the clutches run in oil. The latest DSG from VW, the market leader in these transmissions, runs dry clutches.

It doesn’t matter what Caradvice calls this transmission, it’s a manual with automatic shifting, with no characteristics of a torque converter slushbox.

It has the ability to masquerade as a fully auto transmission, or the driver can involve himself by using the paddles or lever, just doesn’t have a clutch pedal.

Reckless. In what way do you think this is a manual trans?
The duel clutch still works as the torque converter and is submerged in auto fluid, all gear shifting are controlled hydraulically, in the first sentence car advice even refer to the trans as a Dual Clutch six speed automatic transmission? Being a different configuration in shafts and power distribution to the trans does not make it a manual transmission. I’m sorry, having paddles to shift does not mean you are driving a manual princess.

Fan forced, I don’t agree that we are talking about an Auto trans – this article is about Chryslers dual clutch manual with automated shifts.

I repeat my first statement – the torque converter auto is being relegated to history.

Any auto, whether it’s the Falcon one or VW’s DSG can have its decision on which gear to select confused by rapid throttle on-off. Even if the Falcon box can change in .5 second, that’s a hell of a lot slower than the 8ms of VW’s DSG – the DSG can change gears 62.5 times in the time it takes the Falcon to change once.

The DSG box is now appearing everywhere as manufacturers have to meet ever more stringent emissions guidelines, and the torque converter auto can no longer compete.

Fuel injection has replaced carburettors, pretty soon every engine will be direct injected to replace the now primitive throttle body and manifold injection systems.

Meanwhile I’m loving my car with DSG, and direct injected Turbo 2.0l engine. Corolla drivers don’t know what they are missing

So Dynamic, what you are saying is the EVO X can change directly from 5th to 3rd on the same shaft as quickly as a conventional auto in 0,25sec? Did you read that in a review somewhere or are you taking a guess like in your other comments noob? I’m only relaying what I have been told from a major transmission manufacturer? I could be wrong. If there is any proof of this, I am more than happy to eat my words.
Reckless: We are also talking about a automatic trans not a manual, even the latest Falcon AUTO trans predicts what gear you need according to speed and throttle position and can change to what ever gear it chooses within half a second???
Don’t get me wrong, i’m not saying i don’t like the new duel clutch systems, all i am doing is pointing out some disadvantages of this system.

^dynamic, That’s right these are not race cars so why fit largely derived race technology to save 5 more grams/km of CO from the already paltry 200grams the car likely produces. Thinking smarter as you say would result in a simpler solution not a complicated one. This would make things easy and not harder by definition.
…………..based on your irascible response to my thoughts I’d say your sponsor lazyskillessf*cksdotcom wants a word in their office, tewl!!!

Aren’t these more likely to replace automatic transmissions rather than manuals in mass market cars. VW have already said that there will no longer be any automatics in their Golf – it will be manuals or these.

DSG doesn’t need to skip from 3rd to 5th – it can change from 3rd to 4th to 5th faster than a manual transmission ever could.

It is possible to “confuse” the DSG if you try, by changing the throttle to on-off quickly, so it can’t predict what you are doing. But the same problem occurs with a manual box.

The DSG, however, can be put in manual mode, and it will hold gears when you aren’t likely to be travelling in “normal linear” style. You can then upshift with the paddles or the lever, and let the box downshift, which it will do even when in manual mode.

Fan Forced, actually they can. The new EXO X dual clutch transmission can actually do this and is one of the first dual clutch systems to implement this. It’s all in the software and you will see more performance cars implementing this in their dual clutch transmissions.
