DSG gearboxes

The DSG technology was launched in 2003 by the Volkswagen Group. A DSG gearbox is basically two manual gearboxes joined together and controlled by a computer. The DSG gearbox provides high comfort and good fuel consumption. The technology is used by many car manufacturers, but under different brand names. Volkswagen, Skoda, Seat and Audi (V.A.G.) call this type of gearbox DSG (Direct Shift Gear).

A DSG gearbox uses two input shafts where one runs inside the other, both shafts are in constant engagement with the intermediate shaft which means that the gearbox always has two gears active at the same time. The two clutches operate alternately, when one is engaged the other is disengaged, and when shifting, the gearbox switches between the clutches. Based on the drivers style of driving, the mechatronic assumes which gear will be required next and prepares for the change. DSG is appreciated highly appreciated for the seamless shifting, but the technology is complicated.

As early as 2006, Hellsten Gears received the first inquiries for factory refurbished alternatives to original DSG gearboxes. These days Hellsten Gears are known within the industry as DSG experts and can offer both factory refurbished and used DSG units.

DGS as an exchange gearbox

A complete DSG gearbox, factory refurbished or used, is a simpel and safe alternative for all car workshops. Our exchange system leads to a faster and more cost-effective deal and since we offer complete units the assembly will be easier with fewer things risking to go wrong. We guarantee  that the DSG gearboxes we deliver will work in the vehicle. In addition to a complete DSG gearbox, we offer technical support and support both before, during and after installation as well as a nice two-year warranty on both factory refurbished and used DSG units.

The right software for DSG gearboxes is crucial

Every DSG gearbox has a built-in computer that controls the gearbox. The computer receives signals from 10s of computers and control systems in the car. There are incredibly many software variants for DSG and it is absolutely crucial that the gearbox is programmed with exactly the right software to match the vehicle specifications. As DSG industry experts, we know what software each DSG gearbox needs and can customize the software in the computer to suit specific vehicles.
Workshops that buy used DSG gearboxes elsewhere often run into problems. Even though the part number is correct and the DSG gearbox visually looks the same as the broken gearbox core, the software often turns out to be wrong and the vehicle does not work. It is an expensive lesson. Hellsten Gears, unlike OEM and other workshops, can re-program even used DSG gearboxes to match specific vehicles. It is a unique service that simplifies everyday life for our DSG customers.
