How to Choose DSG Transmission Fluid?

When it comes to DSG transmission, ordinary transmission fluid will not do any good. As the DSG has specific viscosity, DSG transmission fluid capacity, and other needs, you need to choose a DSG transmission fluid.

The best way to choose the right DSG transmission fluid is to go through the vehicle manual. Different vehicles have different kinds of needs, and all of these are mentioned in the user manual.

Another common question is where it is possible to use regular ATF for DSG? Well, the answer is no. although some of the ATF doubles as DSG fluid. But most of them don’t. So, double-check before you use one.

So before buying any DSG transmission fluid, make sure it matches all your vehicle’s needs. If you can’t find your vehicle manual, look up on the internet. Otherwise, contact the DSG transmission fluid manufacturer and tell them your vehicle’s model. They will be able to help you.

How to Change DSG Transmission Fluid?

Well, changing the DSG transmission fluid is not as complicated as it may sound. So, let’s dive into the step by step process.

  1. The first job is to find the DSG filter cartage. For this, you need to remove the airbox, battery, and battery tray. You will need a DSG transmission fluid change kit to do so. After removing these, you will find the housing.
  2. Remove the housing, and you will find the DSG filter. Go ahead and remove the filter as well. It helps to cascade the oil fluid and takes in new fluid much easily.
  3. Now take a DSG funnel with pipe and feed it in behind the engine. Now find the DSG drain plug right behind the engine. Unscrew two funnel plugs and let the old fluid drain completely.
  4. Reinsert the DSG fluid pipe and make it finger tight. Screw on the funnel tube on to the adapter.
  5. Make sure to shake the fluid bottles very well before taking off the cap. Now, pour the fluid into the funnel and place the funnel as high as you can. This action will let the fluid go faster.
  6. After you are done with filling the fluid, reinsert the filter and the housing. Replace the seal on the housing and lubricate it well. You can change your filter while you are at it.
  7. Reassemble the battery and airbox.
  8. Start the car and cycle through each gear for 3 seconds. Keep your leg on the brake paddle. Then put it back to the park.
  9. Make a proper adjustment in any DSG transmission software you prefer. When the fuel temperature reaches the required level, do the final drainage.
  10. Detach the DSG funnel tube from the adaptor and let the fluid drain. Wait until the stream gets broken up. After that put on the new seal.
  11. Turn off the car, and you are done. Take a test drive.

Frequently Asked Questions (FAQs)

Q: What does the DSG transmission fluid change cost?

Answer: Well, changing the DSG transmission needs professional help. However, the charge depends on the service company policy. But anything around $300 counts as standard and reasonable.

Q: What is DSG transmission fluid?

Answer: Well, as the name suggests, DSG transmission fluid is a special transmission fluid for a double shift gear mechanism. It is also commonly known as dual-clutch transmission fluid.

It all depends on how the vehicle manufacturer refers to it. DSG cannot be supported by regular ATF due to different viscosity rating and other parameters. That’s why DSGs need specially engineered transmission fluid for them.

Q: What happens if you don’t change DSG oil?

Answer: Old fluid can overheat and burn the clutches. It can also lead to power loss, poor gear selection, and transmission failure.

Q: How often should I change my DSG fluid?

Answer: you must change your DSG fluid after 40,000 miles of the drive.

Q: How does a DSG transmission work?

Answer: DSG systems have two independent manual clutches to control odd and even gears. The gear is changed depending on the speed, brake, throttle position, and hydraulic actuators.

The main part is the computerized hydraulic system that controls the clutch and gear shift. Depending on the driving condition, this unit decides the optimal gear required and adjust likewise.

The dual-clutch gears work as one and provide smooth gear changes in milliseconds. This way, the speed can be varied without changing any other parameters.

Final Verdict
