Five things we should not do with dual clutch gearbox

The dual clutch transmission shares opinions in the automotive world. Search the internet for “Powershift Exchange” and you probably will not find just good news. Or search for DSG or 7G-Tronic.

In that case, the type of demonstrations you will encounter should reveal another story.

However, the two cases have common ground: automated dual-clutch transmissions are fast, efficient and smooth in gear changes, as well as versatile. They can serve a compact vehicle or a supersport.

In a line, this type of exchange makes exchanges like a conventional automatic, but the base of its gears is almost identical to the one of a manual box. Electro-hydraulic actuators mechanically perform the changes, and at each exchange the clutch is actuated – automatic shifters have torque converter.

In the case of the double clutch, one acts in odd gears, another in pairs and aft. In practice, the driver does not have to worry about which one is working. But you should take some precautions to make this box run smoothly for a long time.

We list below 5 cares that will preserve your automated dual-clutch transmission

1. Do not place the gearbox in neutral

On manual cars, one should step on the clutch to uncouple the engine transmission. Dual clutch exchanges do this on their own, avoiding wear on the clutch discs. Therefore, it is not necessary to set the dual-clutch gearbox to “N” (neutral) whenever the car stops.

2. Do not take your foot off the

When standing on a slope, do not take your foot off the brake. In a manual gearbox, the effect is similar to the act of “holding” the car in the same place only with the throttle and clutch.

If your car has a starting assistant, it will remain motionless for a few seconds while you start the throttle. But if you do not do this, the clutch will take action to try to hold the car. This overheats the component and causes premature wear.

In dry gearboxes like the Golf 1.4 DSG and the Ford Powershift, there is no oil to cool the set. Oils dipped in oil, such as the DSG of the Jetta 2.0 TSI and the Hyundai New Tucson DCT gearbox, damaging practices can accelerate oil contamination as a result of excessive clutch wear.

3. Do not walk too long for too long

Walking at low speeds, towing excess weight or climbing the slope too slowly worsens the clutch wear. There are other situations that subject the clutch to not engaging the entire flywheel to maintain speed.

Ideally, you should achieve enough speed for the clutch to engage completely.

4. Gear shifts in acceleration and braking

Raising the gear during braking or reducing the gear while accelerating impairs dual-clutch transmissions. This can happen when the driver interrupts a pickup or approaching a red light that changes to green just before the car stops.

In both cases the exchange will identify the imminence of a stop and the takeover will take longer than normal. The instinctive reaction, of making manual exchanges, is harmful in this case.

5. Do not hold the brake and the accelerator for a long time

Unless you want to measure the zero at 100 km / h of the car, you do not have to step on the accelerator and the brake at the same time. It is another way of enhancing wear on the clutch assembly and overheating the assembly.

Some cars have ways to stop this, leaving the clutch in the standby position and the engine turning limited while the brake is engaged.
