7 cautions for a double clutch transmission

These units are very modern and allow gear changes in fractions of a second, but require specific care.

Double-clutch transmissions were born during the last century and although they did not convince customers at the time, Porsche took them back for its racing cars and then Volkswagen put them on the production line, but it was not until 2003 that the unprecedented transmission DSG went into production in the fifth generation Volkswagen Golf. There are several types, single and multi-disc, dry and bathed in oil, and although it is the wet multi-discs that can withstand greater friction and temperatures, they all require specific care, different in a certain way from those of a conventional automatic with the converter of pair.

They are very similar to a manual gearbox but have two robotic clutches that engage the odd and even gears, respectively, to achieve the fast and smooth transitions that characterize them.

They are in the car purchase offer in some of the Volkswagen Group models, Kia, Ford, Mercedes-Benz, and BMW among others. If you have it in your car or you plan to buy a used car with a box of this type, you should read these tips so that you can extend its useful life and save several thousand dollars on repairs.

You do not need to switch to neutral if you are stopped

When you stop at a traffic light, the computer can detect it and while you are pressing the brake pedal it disengages the clutches to avoid friction. It’s like having first gear engaged with the clutch engaged in a manual car.

Always stopping and braking before changing gears

Make sure that whenever you go from parking to drive, to reverse, or some combination of those changes, the car is completely stopped and you have the brake pedal pressed. That way, there will be no unnecessary friction to wear inside the case.

Keep the brake pressed when stopping on slopes

Returning to the first point, when you are on a slope pressing the brake, the box understands that it can deactivate the clutch to avoid friction. If you let the box hold you back, friction and heat buildup wears down internal components.

In this case, there is a very marked difference compared to a conventional automatic transmission, where when it is stopped, heat is generated because the tires want to turn and we stop them through the brake discs.

Do not start by accelerating abruptly

Accelerating to the bottom to start causes that when the first gear is engaged, it has to be done before a disk that rotates faster than normal and that generates heat and, with it, wear. It’s like pressing the clutch and gas pedal at the same time in a manual car with first gear engaged and suddenly releasing the clutch.

If for some reason you are on a circuit and want to start quickly, you should brake and accelerate slightly and then release the brake, although the time in which you can press both at the same time should be the shortest possible.

Do not go forward little by little

This way, you don’t give the clutch enough time to finish meshing and friction builds up between the internal components. The clutch will be engaging and disengaging as many times as you accelerate and brake, in a very short period of time.

First and last: the handbrake

As in the automatic ones, when you park, let the handbrake resist the weight of the car and not the box in the parking position. When you park, use the parking brake while braking then shifts into Drive and when you start the car, shift into Drive or Reverse first before releasing the parking brake.
