DSG Transmission Fluid Buyer’s Guide
Before you go out and buy just any old transmission fluid, it would probably help to know a little more about various transmissions, the types, what DSG actually is, and more.
What is a DSG
DSG stands for a direct shift gearbox. This is a specific type of automatic gearbox that features 2 clutches. The advantage of using as dual clutch gearbox such as this is that they can shift gears in a hundredth of a second, much faster than your average automatic transmission.
Most automatic cars have a single clutch gearbox, which is quite a bit slower at shifting than the dual clutch variety, with only very few vehicles having a DSG dual clutch. Keep in mind that DCT stands for dual clutch transmission, which is what a DSG is.
What kinds of fluids can be used for a DSG
When it comes to a direct shift gearbox, you do need very specific transmission fluid, DSG transmission fluid. The reason for this is because DSG transmissions have very specific requirements in terms of the fluid’s viscosity, as well as other such factors.
How to choose the right transmission fluid
The best way to check what kind of transmission fluid your specific vehicle requires is to consult the owner’s manual. The owner’s manual of your vehicle will inform you of the specific type of transmission fluid that is required, as well as some other specifics too. If you cannot find the owner’s manual, the type of transmission fluid your vehicle requires may also be stated on the transmission fluid dipstick.
How often to change DSG transmission fluid
Most owner’s manuals will tell you to change the transmission fluid every 30,000 or 40,000 miles. Yes, this is true if you want the best performance, and if you have inadequate DSG fluid. However, there are some products out there, such as the ones which we reviewed today, which can last anywhere from 200,000 to 300,000 miles before requiring a change.

Can normal ATF fluid be used for DSG?
ATF stands for automatic transmission fluid. For the most part, no, you cannot use regular ATF for direct shift gearbox transmissions.

What happens when the wrong transmission fluid is used?
The reason why you need to use very specific transmission fluid for your vehicle has many reasons. For one, using the wrong transmission fluid can cause your transmission to overheat, and in some cases even catch fire. Moreover, using the wrong fluids can lead to severe damage to the gearbox, increased friction, and even total transmission failure.
