Have you ever wondered what the letter “DSG” on your gearstick or in one of our automobile listings meant? We examine the meaning of DSG and the benefits it offers your car.
Direct-Shift Gearbox is what DSG stands for (luckily enough, the German translation has the same initialsDirekt-Schalt Getriebe).
Without getting too technical, this unique gearbox is essentially two distinct clutches that operate as a single unit, fully or partially automatically, without a clutch pedal.

A DSG is either automatic or manual.
Please clarify the distinction between a “DSG” and a standard automatic gearbox. I’m interested in purchasing a Skoda Octavia 1.8 TSI, however the only automatic transmission available is a seven-speed “DSG.” Tim Mould
A) Volkswagen produces the DSG (or Direct-Shift Gearbox), a semi-automatic gearbox. The DSG contains two clutches, in contrast to a regular automatic transmission, which uses a “torque converter” rather than a normal clutch. The next gear is immediately preselected as you choose the current one, allowing for much quicker changes. Because it wastes less energy, the DSG uses less fuel than a torque converter.
The DSG will shift gears for you just like any other automatic transmission, despite the fact that it is technically an automated manual gearbox rather than a true automatic. By pulling up or down on the gearlever, you can also shift gears manually.
Although it costs $1110, you should save some money on fuel by choosing this alternative. The Skoda Octavia 1.8 TSI is more efficient when equipped with the seven-speed DSG gearbox than when equipped with a manual transmission.
Is DSG preferable to automatic?
In a conventional automatic, the torque converter transfers the engine’s drive to the gearbox, whereas the clutch handles this in a manual. Although a torque converter delivers seamless gear shifts, it is less efficient than a clutch-based system since it consumes a thick hydraulic fluid.
The DSG has one benefit over a traditional automatic transmission: it can predict the gear you’re likely to want next and will have it ready for usage. This enables quick and seamless gear changes. An electronic transmission control unit uses data from the engine speed, road speed, accelerator position, and driving mode to choose the best gear and identify the best shift point. Although some manufacturers’ methods are faster than others, each change can be made in less than four hundredths of a second.
How reliable is the VW DSG gearbox?
Both the six- and seven-speed versions of DSG gearboxes have demonstrated their high level of dependability. Failures are uncommon, but when they do happen, they are usually expensive. These very rare defects are typically discovered in older, higher-mileage cars. A “limp home mode” warning that limits power or juddering and noisy bearings while driving are also telltale signs of a bad gearbox.
Don’t allow the failure stories deter you from purchasing a DSG, especially one in a car with an established service history. Almost all DSG gears operate without issue, and some of them are still going strong after more than 100,000 kilometers on the clock.
Can a DSG be operated like an automatic?
If you are accustomed to operating a conventional automatic transmission, you will have no trouble operating a DSG gearbox if you have familiarity with the latter. Additionally, adaptive cruise control with stop/go capabilities may be an option for vehicles with automatic transmissions. The automobile will therefore automatically slow down to maintain a safe distance from the vehicle in front if you approach slower-moving vehicles in your lane while on a programmed cruise control speed.
Stop/go systems will stop the car completely if traffic comes to a standstill and restart moving once the car in front moves forward, however you might need to give the throttle a blip to indicate you are ready to proceed again. As manual cars would stall without the driver disengaging the clutch, this is not available on them.
How long is a DSG good for?
Since the DSG box uses a wet clutch system and is far softer on the clutches than a human driver, it should survive well over 150,000 miles before needing a new clutch.
Driving a DSG in heavy traffic?
How to effectively operate a DSG transmission in a traffic congestion
- The N position on the gear selector is not advised.
- Avoid regularly alternating the gas and brake pedals while driving relatively small distances.
- Allow the vehicle in front to pass you at a distance of around 5 meters, then follow it in first gear at a slow speed.
Which VW vehicles have issues with the DSG transmission?
The impacted VW models include the Golf, Polo, Jetta, Beetle, Passat, and Caddy. The impacted Skoda models include the Fabia, Rapid, Octavia, Yeti, and Superb. About 23,000 automobiles, according to Volkswagen, may be impacted by the problem, but the company wants to check 40,000 more to be sure.
How quickly can a DSG shift?
Hold your horses Quick-draw Mcgraw, for despite how much you enjoy changing a manual transmission and possibly even believe that you are the fastest shifter in the world. A DSG transmission can change gears in about 8 ms. You won’t be able to shift into the next gear as quickly as one of these rapid-fire automatics unless you have super-shifting abilities.
Advantages of a DSG gearbox
- DSG-equipped vehicles typically have lower overall fuel consumption than conventional automatic vehicles.
- Because the gears are already selected, shift times are typically less than with traditional automatics.
- A DSG doesn’t require manual operation, even though it still requires clutches, which takes part of the stress off of driving.
Disadvantages of a DSG gearbox
- Pre-selection of gears helps speed up changes, but a DSG gearbox can’t predict which gear you’ll use next. This can result in reluctance in unforeseen driving conditions.
- If you choose a car with a DSG instead of a manual transmission, the price of the vehicle will often increase.
- Due to their complexity, DSG gearboxes can be difficult to fix when they malfunction.
How to drive a car with a DSG gearbox
Driving a vehicle with a DSG transmission is essentially the same as driving any other automatic.
- As you turn on the car, keep your foot on the brake.
- Put your gear selector in “D” while keeping your foot on the brake.
- Pull back on the handbrake
- The moment you let go of the brake, the vehicle will start to move.
After that, just concentrate on utilizing the throttle and brakes. Keep your foot on the brake when coming to a stop to prevent the automobile from edging ahead. Lift the brakes off gradually when you wish to move forward again.
Holding your foot on the brake, bring the vehicle to a complete stop as you finish operating it. To stop the car from rolling, put the handbrake back on and shift the gear selector into “P.”
With a DSG gearbox, you can choose to manually shift gears as well, though you won’t need to press a clutch pedal. Using the paddles with the symbols ‘-‘ and ‘+’ on the back of the steering wheel, you may precisely regulate when the vehicle shifts gear.
The downshifting symbol, “-,” is on the left, and the upshifting symbol, “+,” is on the right.
Alternately, some versions let you shift gears directly with the selector.
How frequently should a DSG transmission be serviced?
It is crucial to keep your car maintained and to use the right tools and fluids if your car has a DSG or S Tronic gearbox. This page briefly discusses how to get the most out of your DSG or S Tronic gearbox at all times, as well as what you should and shouldn’t do with them.

As you can see, wet clutch transmissions make up the majority of these. The gearbox comes with two “wet” multi-plate clutches in an oil bath for engines with torque more than 250nm (sic). The dual clutch is cooled, the gears are greased, and the hydraulic shift position is maintained by a shared oil circulation system. Another justification for why maintaining the gearbox well is essential to keeping everything in top shape
On to the crucial details. How frequently do your DSG or S Tronic gearboxes require maintenance? Every 40 thousand miles or so, depending on the vehicle model, an oil and filter service is advised. Some gearboxes simply need oil, and some models even boast maintenance-free sealed-for-life gears (we know, right?).

What we advise will depend on the type of car you drive, the gearbox, and the tune (APR Stage 1, Stage 2, etc.).
We advise cutting the service time in half from 40k if you have a Stage 1 APR for an MK7 Golf R with the 7 Speed DSG DQ381.
There is software available to increase the control of the gearboxes in the form of DSG remaps, and we have additional information on the advantages of remapping your gearbox here. Some owners notice their gearbox moving at irregular intervals, especially down the gears.
Is manual more dependable than DSG?
In general, DSG will be more dependable than manual. The DSG is undoubtedly the most dependable and possibly the most effective twin-clutch available. The manual offers a ton of cheaper alternatives and is the free choice.

What is not possible on a DSG?
Driving is a lot of fun, period. When a manual transmission is added, the fun is increased. The experience of shifting gears and using the clutch mechanically all contribute to the enjoyment. But it’s hard to imagine that automatic transmissions have become commonplace given the shifting rhythm.
These automatic transmissions include torque converters, CVTs, and DSG or DCT. For your information, both DSG and DCT are dual-clutch gearboxes that use a same core gear-shifting concept. The DSG automatic transmission is the subject of discussion today. Volkswagen vehicles often have DSG automatic transmissions; the Polo GT TSI was no exception.
Unfortunately for the BS6 vehicles, Volkswagen does not pair its existing 1.0-liter TSI powertrain with a DSG transmission. Instead, this brilliant motor now has a torque converter that, while not as quick or fluid as a DSG, nevertheless performs admirably.
Regarding its competitors, Hyundai likewise provides its own DCT automatic transmission. The company’s two GDI engines are paired with this quick-shifting gearbox in India. Speaking of which, this line of vehicles offers 1.0-liter and 1.4-liter turbocharged gasoline engines.
Although the DSG automatic transmission is simple to use and provides some incredibly quick and accurate shifts, it is definitely maintenance intensive. In addition, we need to adjust our driving habits in order to protect this transmission.
There are a few things you should never do when using a DSG or dual clutch automatic transmission, so don’t worry. Let’s have some enjoyable lessons before we begin.
Working on a DSG Box
The short version is that a DCT or DSG has two shafts, one for the odd gears and the other for the even gears. Dual-clutch means there are 2 separate clutches for each of the shafts. The second gear on the other shaft is selected and prepared for engagement as the first gear is engaged. The clutch is engaged as the car accelerates, requiring the second gear.
When either we or the transmission downshifts, the same thing occurs. In addition, they require some modifications to our driving techniques so that we don’t damage this speedy transmission. There are a few things you should never do when using a DSG or dual clutch automatic transmission, so don’t worry.
