2009-2015 Cadillac CTS-V General Discussion Discussion, Torque converter on a DSG transmission? in Cadillac CTS-V Series Forum - 2009-2015; I was reading on cadillacfaq, that the 6 speed Tremec TR6060 has a torque converter? I thought by definition the ...
A DSG doesn't use a torque converter either as far as I know.

The Direct-Shift Gearbox or DSG (Direkt-schalt getriebe) is an electronically controlled, twin-shaft dual-clutch manual gearbox, without a conventional clutch pedal, with full automatic, or semi-manual control. In simple terms, it is two separate manual gearboxes, contained within one housing, and working as one unit. It is designed by BorgWarner and initially licensed to Volkswagen Group (which owns the Volkswagen, Audi, SEAT, Bentley, Bugatti, Lamborghini, and koda brands). By using two clutches, fast shifts can be achieved, and the torque converter of a regular automatic transmission is eliminated.
The '09 CTS-V comes with two transmission options:
- traditional 6-speed manual (TR6060) which does not have a torque converter. It's used on the Shelby GT500, Viper and upcoming Corvette ZR1.
- traditional 6-speed automatic (6L90) which does have a torque converter
Yes by using the words traditional I'm downplaying some really good technology, but it looks like that most car manufacturers are switching to DSG (double clutch) technology. I'm hoping that the '10 V model will bring us a DSG option. DSG's do not use torque converters.
Have been an advocate of automatics for many years. Matter of fact, I've argued MANY times in favor of them in drag cars purely for lower ET's but...
If I'm not rowing gears myself, I have no use for a sports car/sedan. I know it means the car may actually be slightly slower but IMO, that's just part of what makes a sports car, a sports car. And that's why I am generally no fan of a car that has to have all kinds of electronics to be able to be driven at it's limits.
DSG is fast, and great about 5% of the time. The only one I drove was VW's (which from what I read, is the best currently on the market.) It was fine when you are on it, but at a leisurely pace, it lurches at low speeds. And the take off seems shaky. Hopefully future generations of DSG will have computers with better clutch-slipping skills.
