The DSG6 was the first dual-clutch automatic transmission produced by VAG in 2003. It is a revolution that led to a radical change in the driving concept, in addition to opening the way to automatic transmissions production, intended for non-premium vehicles; just think that in 18 years of production have been sold over 26 million of cars equipped with DSG!
The first car to equip this gearbox was the R32 Golf, introducing the “R” logo, that still today wears the most powerful and sporty versions of the Wolfsburg compact car.
The transmission is designed, like all “DQ” gearboxes, for transversal mounted engines and holds a maximum torque of 400Nm, besides this you can use it for both front-wheel and four-wheel drive models.
In this case, the gearbox uses two primary shafts that respectively operate the even and odd gears linked to two wet multidisc clutches. What allows the speed in shifting of this transmission is the fact that while driving the gearbox has both primary shafts with engaged gear, that’s why, to complete the transition from one gear to another, it will only be necessary to move the two clutches to disconnect the shaft with the previous gear and to engage the shaft with the next gear. Obviously, the scaling has the same principle of operation.
The automatic transmission is managed by an ECU that, based on the parameters set in the map, reduces, or increases the torque, depending on whether you up or downshift. Furthermore, the TCM applies the rev matching during downshifting, the “sailing” mode in the last versions and also the “Tiptronic” mode (sequential manual gearbox).
The parameters you can work to improve gearbox performances are torque and rpm limitations, oil pressure of the hydraulic actuators, times and shifting threshold.
