Understanding Volkswagen’s Direct-Shift Gearbox (DSG)

How Does It Work?

The DSG, also known as a dual-clutch transmission, is an automatic transmission system that shifts gears faster than any other transmission system currently out in the market. Originally created and marketed by Volkswagen, this product can now be found in other brands like Audi, Hyundai, and Porsche.

The system utilizes two different gearboxes — one for odd numbered gears and another for even-numbered gears. While your vehicle shifts gears, these gearboxes will predict and pre-select the next gear in the sequence based on your speed and behavior. Once you shift gears, the transmission uses the clutch for an almost instant switch, with the switches timed at only 8 milliseconds!

The History

Before the DSG, there was the sequential manual transmission (SMT). The SMT was designed to provide automatic transmission drivers the same performance a manual, stick-shift driver experiences. Although it allowed 100% of the power to be transferred from the engine to the wheels, it still had the big drawback of complete disconnection from the engine and transmission in order to change gears, which disrupted the flow of power. With the creation of the DSG, this essentially eliminated the need to disconnect the engine and transmission in order to switch gears and provided the smooth and seamless transition that the manufacturers were looking for.

Pros and Cons

Are you considering a Volkswagen vehicle with a DSG? Well before you get it, it’s important to understand the pros and cons that come with it. Although it may not seem like it has any cons, there are a few you need to pay attention to before making a purchase, as some of them may affect your overall driving experience and lifestyle!

Pros

The biggest positive that comes with driving a DSG vehicle is that you get the benefits of driving a manual and automatic vehicle. Shifting between gears is almost instantaneous, with the shifts being timed at 8 milliseconds to upshift. This leads to faster acceleration and an improved driving experience! Along with that, drivers also experience a 15% boost in fuel efficiency when driving this vehicle versus a conventional transmission system.

Cons

A big negative that comes with this component is that due to its complex operation and design, it requires more, specialized maintenance and repair services to keep it going. For Volkswagen models, an owner can expect to have the DSG serviced every 40,000 miles, but that number could decrease based on your driving habits. Along with that, there are only a fixed number of gears within the transmission system. Due to this, it can’t maintain or extract the best speed for maximum fuel economy or power.
