5 Things You Should Never Do In A Dual Clutch Transmission Vehicle

5 Things You Should Never Do In A Dual Clutch Transmission Car

Don’t put the transmission in neutral when you come to a stop. There’s no need to do this. You may think the clutch will be partially engaged and wearing out, but the system will be sure to disengage the clutch (while keeping first gear pre-selected).

Don’t take your foot off the brake when you’re on an incline. The clutch may attempt to hold the vehicle. Unlike in an automatic transmission where you have this slip absorbed by the torque converter, this will directly cause wear on the clutch. Depending on the design, the effects can be even greater with a dry clutch, which has no oil around it. Wet clutches tend to be able to take more heat, however dry clutches are more efficient, robs less power (used on sports bikes), it weighs less, and often requires less maintenance (there’s no clutch fluid, it’s all electronically actuated on Hyundais). For Hyundai, owners are asked to inspect the fluid levels every 37,500 miles on the DCT, but there is no set time to replace fluid.

Try not to spend much time inching forward (especially while towing or on steep inclines). Stuck in traffic on a hot day, crawling up an incline at low speeds, or towing. In these scenarios, it’s best to allow yourself enough gap to get up to speed, so the clutch pack can fully engage. At low speeds while partially engaged, the clutch will heat up and can wear faster. It’s never ideal to slip a clutch, but they are designed to take wear and tear. This advice is to simply have the clutch last as long as possible.

Upshifting while braking, downshifting while accelerating. Need to understand the logic behind the system to understand why shift delays might occur. For example, driving on the highway, 4th gear, hit the brakes because someone cuts you off. Upshift and it takes longer than usual. Well because you were on the brakes the transmission might have assumed you were going to downshift next. Coming to a light, if it’s red but turns green, the system may have been attempting to disengage the clutch knowing that you were coming to a stop, so there may be a slight delay in getting power.

Don’t hold the brake and throttle long if launching the car (launching your car in general is a bad idea for longevity, but if you were to do it, know what’s happening internally). This will cause the clutch to wear, all of the heat from the engine is going into the clutch (if it’s engaged, depending on the car). From Hyundai - “The engine speed should rise and the clutch should go to a stand by position.  The clutch may try to engage and if it identifies no vehicle movement it should reduce the engine speed and hold that speed until the accelerator pedal is released.”

If you press the gas and the brakes at the same time your car will take a screenshot.

Number 6: don't breathe inside the car, the difference in air pressure and moisture causes unnecessary wear on the clutch

Thank you for these videos. This is a concept called mechanical sympathy. Understanding how a system works in order to prolong lifetime of components. This higher lever of understanding makes you a better operator.

"Try not to inch forward too much."


RIP city drivers...

One clutch is enough for me. Man can you imagine driving with two clutch pedals? No thank you

[le-mon]

according to the thumbnail, you can't upshift

Hey Jason this is a fantastic video! I just picked up my first car ever with a DSG and knowing about the ECUs favoring towards gears depending on driving behavior is great to know, otherwise, I could see myself getting frustrated with a delay when wanting to downshift to accelerate.

I can't tell if this guy is 20 or 40.
Like hell. He's ageless.

I really like these "don't do in a" series, I've learned quite a bit, please keep doing them!

[thecarguy]

thank you, I just bought the veloster 2019 with 7 speed dual clutch and those information will be usefull !! good video

[NaiR]

"...engineers who develop these cars smart enough to realise that problem...": doesn't surprise me how a lot of people in comment sections don't realise that, especially in regards to auto start/stop and engine starter motors.

[Evoinsec]

This is great, just brought a Tucson months ago and I have been doing all those good practices, only dont know abouy is number 3 but now I know ! Thanks

6. If your dual clutch transmission was made by Ford, trade in your vehicle for another brand immediately.

[davidjean]

Thank you so much for the time you put into these videos. They're honestly very informative. I do have a general understanding as to how cars work. But not a clue when it comes to the engineering and design. I really do appreciate the information. I just purchased a new 2017 Kia Forte 5 SX. And your videos have really showed me how to take care of it and keep it on the road for as long as possible.

[FordTechMakuloco]

Good information! Most of these newer vehicles have Hill Start Assist now that leaves the clutch disengaged and holds the brakes for you until you accelerate going forward.

[JayTac]

Can someone explain why Hyundai puts a dual clutch in an suv and a slushbox in the gen coupe. Wtf.

[TheFknRadish]

With VCDS linked to a vehicle with DSG there is pressure being applied to the odd gears clutch when stopped tho.. roughly 30-35psi

[bobdadruma]

It took me several months to learn how to predict the actions of my Hyundai Tucson's DCT. Once you master the art of understanding the quirks, it is an awesome transmission. Great video! I really enjoyed watching it and you really nailed it. I am a senior level experienced Automotive Technician by trade and I found the DCT hard to master. You explain the logic or the DCT so well in this video. I really like your channel.

[RobWhittlestone]

Brilliant Jason! After driving manual transmissions all my life, I'm about to buy a DSG. Glad to have seen this! I LOVE your channel. Please keep 'em coming! All the best, Rob
