- Don't Do These In A Dual Clutch transmission vehicle!!!
Driving a sportscar with a dual clutch transmission is the way of the future! Even normal cars are coming with these types of transmissions. They utilize two clutches similar to how a manual tranmission works. However the computers control the actuators and there are separate clutch plats for even gears and odd gears. A dual cutch transmission is a type of automatic transmission but is much more engaging to drive then a torque converter automatic. I really enjoy what DCT transmissions offer! In todays video we go over things you should not do in your dual clutch transmission if you really want to prolong the life of the DCT! Dual clutch transmissions are generally light weight and more compact then traditional torque converter automatics and offer quicker gear changes and more response!

I have a feeling a lot of the people who complain about jerkiness and hesitation in DCTs just don't understand how they work and try to treat them like an automatic. They definitely require a bit more thought and foresight to drive smoothly, but leaving gaps and keeping stop and go to a minimum is pretty standard for economical driving in general.
Very true. When you understand how a DCT operates vs a torque converter, it changes your whole driving mindset.
You have to accelerate kinda fast for the computer to learn the gas pedal right way to avoid any shudder
It's all about gas pedal control and understanding how the clutches engage upon line pressure increase. I can make my DCT sound exactly like a manual trans if I want.
I have a Elantra N with the DCT. Coming from a 6 speed manual, the DCT is very responsive, and fluid. Good to know some of this tidbits. 👏
Nice hearing about these tips, I recently got my drivers licence and take my dads vw golf7 quite frequently, it has a 1.8 tdi with a dsg as well and I genuinely love how it drives. Quite weird is that the hill start assist for some reason does not disengage automatically, only when you press the accelerator, in this car it is called auto hold, not sure if that is different from hill start assist, also a green light comes on the dash when it's active, to be honest I like it better this way because at traffic lights you don't have to constantly hold your foot on the brake
I thought you did a video on this but were driving your GT-R. Never hurts to do it again.
All excellent points.👍
Yup! Did it about 3 years ago. Always good to do refreshed version 😎
I'll stick to manuals until they don't make them anymore, which hopefully never happens. I don't track or race so the .5-1 second saved on every shift doesn't matter to me. I just like not falling asleep with boring-driving cars.
Yeah manuals are a lot of fun for sure! Still a good amount offered in todays market!
Whatever floats your boat
Hello , Ioniq dry DCT here, then when you are in a bumper-to-bumper trafffic what you must to avoid is to release the brake pedal without press the gas pedal, right?
An advice to those with DCT and adaptive cruise: if you get in bumper-to-bumper trafffic, set your following distance to max. At those speeds, the car will maintain a following distance large enough to just continuously drive in first gear. It's always better to move slowly than to stop-and-go, and drivers who need to get to the exits in such traffic will appreciate the distance you leave, as they can use your gap to pass.
Yeah I love that feature in automatic cars! Very nice to have for sure!
What about just switching to manual and using first gear? My Africa Twin motorcycle was DCT and slow speed maneuvering offroad, that is a must in adventure riding, was done via manual mode and using the paddle shifters!
@@jammcguire1276 first gear is too short for that, half as short as a first gear in a manual. In a manual you can push gas until 3500-4000RPM in first gear and get to 30-35km/h, in a DCT you'll barely get to 20 and it will blow hot air at you. In addition, throttle response is very jerky in first gear. So better to just let it shift but leave a good room so it doesn't slip the clutch as much.
the MK3 focus Sedan i have has launch control, and it's super fun for the economy car it is. It's super fun! It also has a DCT, at one point was recalled but... hasn't given me issues. The shifting is crazy in manual mode and helps when i'm driving the canyon road, i can shift down to 3rd real quick when i need to shoot out of the turn, then as you mentioned, 4th gear is already ready, and when i shift up, its that fast!
Dang that’s cool! Didn’t know they even had a DCT back then!
@@BrosFOURRSpeed it actually came with issues, trans fluid was getting onto the clutches and they’re dry clutches. But it hasn’t given me any issues so far! My favorite part is that launch control tho. Said before, the Audi’s launch control is dirtyyyyyyyy🤣
Impressive! Nice to see yours is running well. Launch control is always fun! Very impressed with the S3 and how quick it is
@@BrosFOURRSpeed the S3 sounds amazing too!
Hey can you do another video on tips of driving a dct, would help if you cover the points on driving down hill.
After driving the new BMW ZF box in the M3, I've kinda started loving the torque converter once again. It's very responsive and downshifts with ease, not to bash DCTs but their extra maintenence costs and fragile nature makes me prefer BMWs conventional modernized sport auto. With the Beemer in real life it's hard to tell the difference in shift speeds against a DCT especially when it's turbo is nullifying any loss of momentum one might expect. Audi also uses this system in their RS5, I hope you try it if you haven't because it's the best trade off I've ever experienced which also allows you freedom to creep in traffic without clutch judder.
What extra maintenance costs are you referring to? I owned a GTR for 5.5 years with a DCT and there was nothing in maintenance to do with that! Had 50K miles on it when I sold it, and no issues came up. The ZF is definitely a great automatic for sure, both of them would be the one to get for a true sportscar and quick shifts!
Clutch packs are often needed to be replaced in VAG DCT's at 75k miles upwards - esp if aggressively driven. We see a lot in the service dept. @@BrosFOURRSpeed
Does it affect my clutch if I press the accelerator at the same time when the Auto Start/Off is trying switch off the engine? That happens a lot in traffic and it worries me. I always Auto Brake though.
hi, current own Kia Sorento 2021 with the Wet Dual Clutch Transmission, I really want to know more about the WDCT , tried to search more about WDCT online but Not much info. just really wanted to learn how to prolong the lifespan of WDCT, thanks
I'm sure any DCT is similar on how to prolong life. I don't know all the specifics on wet vs dry tho
I'm interested in you reviewing a new BMW X1 that now has a DCT.
Coming this week!
A dual clutch transmission (DCT) does not need a torque converter or a clutch pedal. The first clutch controls odd gears and the second clutch controls the even gears. Volkswagen's Direct Shift Gearbox (DSG) is one of them.
Yeah DCT systems are fun to use!
My BMW DCT doesn't creep. It only moves when you tap the gas.
Have a new Santa Fe. The worst part about the transmission is you cannot stop smoothly. In my normal automatic car, I feather the brake and let off very slowly so that I come to a very nice pleasant smooth stop.. You cannot do that in a DCT, you can feel the engine start to big down and the clutch start to slip and the car does not like it... Only option is to just brake abruptly so that it never gets to that point of the clutch slipping... Might just be a thing on the santa fe, but I absolutely hate it and I am very glad it is my wife's car and not mine lol. It drives me nuts
how does the DCT work in the 2023 BMW X1? I've been trying to find it online, but there's very little talk about it... :( Thanks!
Pretty much like any other. Two clutch packs in the trans. One for even gears and one for odd
@@BrosFOURRSpeed so all the things that one should not do in other cars with DCT also applies to the BMW X1's DCT? :) Thanks!
@@S_Paoli most likely! Fundamentally all DCT’s are the same
Being a driver who actually loves driving his 2017 Fiesta SE, this is a great video. The most basic functionalities you cover here, are all present on Ford's DPS6 DCT, used on both the Fiesta and Focus automatics, as well as other vehicles, which became a very hot point in the early 2010's, and lasting several years. Ford never trained drivers of it's DCT's, how to drive them properly when they bought them new, and it had several large issues with the DPS6 early on. Perfect storm... As you highlight well here, they should NOT be driven the same as a CVT, or a hydraulically actuated automatic. I WOULD PUT GOOD MONEY, ON AUDI AND VW AS A WHOLE, having an in-depth training video you are asked to watch, on buying your new DCT car, which trains you on operating the DCT's correctly, and optimally.
Glad you liked the video! Yeah most people who aren't car enthusiasts wouldnt even know a difference from a CVT, DCT or torque converter. To them they are all automatics. So it's always nice to understand how your transmission woks to better drive it
A lot of new DCT drivers, who are unaware of how a DCT transmission really works, think it should feel like a hydraulic clutch, or CVT, without much noticeable forces occurring at shift points, or, in fact, no shift points at all. It should feel like a manual, only faster, shorter, and smoother shifting in economic modes in low gears, and longer, higher rpm lower gear shifting in sport modes.@@BrosFOURRSpeed
Maybe I've missed it in the video, when you come home in d/s can I just hit the parking button? Or should I go to neutral first and then press the park button?
You can go straight to park!
There was once where I put my car (having DSG trans) in M1 mode while I was stuck in a traffic jam, and was just crawling in M1, suddenly my gearbox high temp alert came on, and I had to park the car on the road side to let the gearbox cooldown. Question, is my putting of M1 gear while crawling the root cause of gearbox overheat?
It was probably the crawling that did it, but it's also possible that the programming for your car in manual mode could have also contributed here
Let say if i in a traffic light that is really long to wait, can i just put a handbrake on at drive? Or better to put in neutral?
Technically you could just use the handbrake, but you could put it in neutral too. Most newer vehicles have an auto hold feature which is cool, unless you don't have that.
So do cvt's shift themselves in manual or you can shift yourself or is it like a dct
CVT transmission don't have gears. It's two cones that spin with a chain on them. The chain just slides back and forth to change the 'gearing'. Some new ones have a manual mode and the computer basically has preset spots for the chain to be to simulate gears
This could be a stupid question but at 6:14 when you’re explaining at the stop, you’re recommending putting the car into drive instead of keeping it in the manual +/- ? TIA! So then taking off…put it back into the manual +/- ? Again sorry but thanks !
I didn’t make that comparison. I was talking about between drive and neutral.
Drive and the “manual” mode doesn’t make a difference, those are essentially the same.
@@BrosFOURRSpeed oh! My confusion, thank you for clearing it up 🫡
You say it automatically puts itself in a neutral
Mode when stopped, are you sure as if you do not hold it on the brake does the car not creep forward?
..actually last question - do you think it’s necessary (unless trying to gain power) to try and down shift when slowing down, coming to a stop before the car does it for you? 🚗💨
No you don’t have to do that, you can though, either way is going to be fine just depends on what you feel that day!
Always remember......Brakes are cheaper than transmissions
@@daveallen2455 that’s a really damn good point! Rather burn through brakes than ever have to think about that lol
My car Mercedes GLA '16 DCT is vibrating when stopped in D. While putting it in nutral doesn't vibrate at all and the rpm rise slightly. So the clutch definitely engage. The manufacturer manual doesn't say anything specific for the transmission while driving in traffic or stopping at headlights. What shall I do?
My Nissan GTR did that a little bit. I'd put it in neutral sometimes. If you do any tuning, you can adjust the clutch capacitors to be less sensitive in 1st gear. If not, just pop it in N
So if I'm cruising down the road in 3rd with the DCT ready to go into 4th, but then decide to change lane and accelerate hard, the DCT has to shift to 2nd, there's a slight delay as the DCT quickly tries to change from the pre-chosen 4th gear to 2nd gear. In this case what is better, should I live with the slight delay and let the DCT do its thing or should I pre-emptively manually change into 2nd and then make the lane change?
^^
If 4th gear was preselected, you’d still have a delay even if you manually selected 2nd.
Dct tune will help this
creeping in traffic is no different when you were driving a standard stick transmission. So whats the issue?
Yeah the DCT operates similar to a manual. Creeping in traffic in either transmission slips the clutches. It's better to not constantly slip the clutch weather its a manual or DCT
Is it bad to shift to neutral on long Signal lights ??
You can. Not really any point to do that tho. Could just pop it in park if you want to just sit there for a bit
and this is why i want a rs3
RS3 is a super cool car! Love they use a DCT
In a torque converter auto when stopped for a while in traffic it's ok to put on the handbrake while leaving it in Drive so you can rest your foot. I do this quite a lot.
Is this possible in a DCT or would the clutch be slipping while the car is just being held by the handbrake?
Yeah I feel in a DCT the car knows when you take your foot off the brake and tries to engage the clutches. So i'd put it in neutral if you're going to do that
If you have a DCT but only use it as an automatic, is that bad for the car?
No, why would it? That’s what’s it’s designed for, it’s an automatic.
When do we use the neutral? What is the purpose of the neutral mode?
Maybe if you have to push or roll the car. So not really common to use it
@@BrosFOURRSpeed Thank you for the clarification.
.. to go through the carwash.
Also to ease the transition between Drive and Reverse!
In what scenario do i use neutral in DCT? From what i understand, you don't need to put the car in neutral during traffic. So what is the neutral for then? Sorry if it's a dumb question I'm new to DCT
Really could depend. But generally you'd just use P,R,D. Maybe if you need to push the car for whatever reason you can put it into neutral. Or if your revving it lol
@@BrosFOURRSpeed thank you for the prompt reply. Last question though (sorry 😅) during heavy traffic, can i put the gear in park? In the video you said that we just need to step on the break during a stop light however from where i live, it's usually standstill in heavy traffic. Let's say 5-10 minutes standstill. Can i put it in park? I think stepping on the break for 10 minutes straight isn't good.
You can definitely put it into park. Just make sure you pay attention and if you need to make a quick maneuver, be ready to go into gear. But times of crazy traffic I've definitely done that when I'm not moving for a long time
The Hyundai I30N DCT is super slick. Fantastic gear box.
Does your car automatically up shift when it's close to red line in manual mode? I've seen some Audi's do that.
Yup! Weird that it does that. I think its the same even in the RS3
@@BrosFOURRSpeed even the VW Golf does that. Must be because Audi is owned by VW group & it's cheaper for them to use the same technology for every car
If you own a hyundai veloster, you have been warned also,anyone with a cvt box in the nissan range, these manufacturers need to be held accountable. Nothing is ever built to last anymore, and families are far worse off financially
One thing that is not entirely correct.
A DSG gearbox is not like an automatic gearbox with a regular clutch instead of a torque converter.
An ald school automatic is a torque converter with a set of planetary gears to shift gears.
Manual is a set of gear pairs connected to a clutch.
A DSG is more like 2 manual gearboxes with regular clutches that is controlled automaticaly.
So it is more like 2 robotic manual gearboxes coupled each with a regular clutch.
And that is the beauty of it. It has the efficiency benefits of a manual gearbox (since it is two manual gearboxes) while simultaneously having most of the benefits of an automatic gearbox (since it is robotically controlled)
The main downside is that with a torque converter you can basically creep on the torque converter (in stop and go traffic) indefinitely as long as the cooling system is working) without damaging the gearbox.
With a DSG you will eventually wear out the clutches in stop-go traffic since this causes a lot of wear on the clutches.
You could of course create a DSG with two gearboxes with planetary gears (as in automatics) and couple them with two clutches but since planetary gears are heavier it would not get as good fuel economy as a gear pair geearbox.
Seems like the Audi DSG is like any other dual clutch right?
You can downshift fast while accelerating, you just have to press the gas petal a bit before shifting. This way the DSG preselects the lower gear instead of the higher gear.
If your accelerating, your foot is already on the gas pedal tho
@@BrosFOURRSpeed true, but depends on if you were already accelerating or just started. If you are coasting and already in a high gear, if you depress the gas hard enough the DSG will pre-select a lower gear instead of the higher gear. It works off the same logic as if you were in Drive.
Also it’s nice to stay in Drive because the DSG will automatically skip gears when downshifting. ie from 6 to 4 or 6 to 3.
@@timeformetoact6 Yeah I'll have to try that and see how it works on these cars. interesting way to do it
I tried it yesterday, cruising around 65mph, press gas to about 80% or more quickly, it drops to 3rd after about 1 second delay and takes off. Then it will quickly up-shift back to 6th so fast didn’t even notice if it skips up.
About creeping. How would you creep with manual transmission. I do not see how it would differ from manual. In such a traffic you just creep 😄
Pretty much the same. In a manual you'd just feather the gas and let off the clutch a bit to roll then your press the clutch and stop. Similar concept. You'll be slipping the clutch. In both transmissions just try to limit creeping to not slip the clutch so much
Mine does not rev
I was going to buy kia ceed estate with this transmission and changed my mind these gearboxes shit!! I will burn it if I tow a boat!
Oh wow!
You say durable? How many miles do the last on average?
I've seen DCT cars with well over 100k miles on them. Even a Lamborghini Huracan can hit 150k with no issues. Just depends on who makes the transmission. Like anything, some will be poor build quality and others will be bulletproof .
@@BrosFOURRSpeed ty, I definitely can't afford a Lambo. I will flip a coin on a Santa Cruz.... I don't plan on towing and I'm to old to race so hopefully it will last awhile xd
@@1976axerhand A car like that should be fine for a long time. At least it comes with a 100k mile warranty
@@BrosFOURRSpeed thx. that 100k warranty is the only reason i got it, and it can't be any worse than fords try at a dct? lol
"Launch control"....WHY????!!! Like what's the purpose??
To go really fast. It's pretty fun to use launch control in a fast car. People who like sportscar enjoy the fast acceleration
@@BrosFOURRSpeed guess I’m old school…..bc for me to “really go fast” I downshift and depress the accelerator🤦🏾♂️
Man creeping you can’t help.
Sometimes you can. Just leave more room
Either your DCT is worn out or it's a shitty DCT. My BMW M5 DCT shifts 20 times faster than yours.
When did I say this one is worn out? I'm just pointing out the best ways to prolong the life of a DCT
@BrosFOURRSpeed I said it shifts slow af. Clutch slip. You need an XHP trans tune.
@@22Pachanga nothing is wrong with the car in this video..
No thanks . I don't need a unreliable car.
You think a DCT is unreliable? How so?
@@BrosFOURRSpeed from all the breakdowns all over the net and all the clutches burning up stuck on the interstate in traffic. Your transmission overheat
@@short5stick Never had a single issue! Had my GTR 5 years, full bolt on, E85, not a single transmission problem with the DCT..
@@BrosFOURRSpeedbut...the internet told him it sucks...internet would never lie,right? Deerrrpppp :E
1 thing you should never do when driving a manual transmission... put it in neutral when coming to or at stop. 🤣
Why? I’ve done that for years, it’ll save on clutch wear while you aren’t moving or even coasting. Nothing wrong with doing that at all.
I always neutral at a dead stop
@@zrs1 Yeah me too, it saves on your left leg and the clutch!
@@BrosFOURRSpeed if it's on a flat surface I don't even need to have my foot on the brakes either, gotta be mindful of traffic coming from behind you though , I tap the brakes a few times first, specially if they're closing in fast.
Sitting there with the clutch engaged wears out the release bearing. Definitely be in neutral at stop lights, and don’t rest your foot on the clutch.
Don't advertise DCT of manufactured can't fixed a bugs , automotive industry always throw out to consumers to drive the vehicle instead of tested to fixed a bugs . Automotive industry intended to do this, instead of allow quality control to tested first for 5 years but throw it out to consumers than denying problems and claiming consumers abused, and than now after 16 years everyone thinks they know it all bro.
What are you talking about?
@@BrosFOURRSpeed if you don't drive manual for 50 years or fixed them you don't know what I'm talking about Bro. Without damage wears or replacement parts bro., if they can't perfect old automatic transmission, than don't add any more problem, and I bet you don't know who fixed the problem of GTR for 5 years with bug problem when it first came to market ?! All technicians all over America refused to fixed them or Nissan engineers scratch their heads , mean while paid someone cheapest labors for their mistakes
Just buy a man's transmission
So I guess all of the supercars just aren’t for you then? Unfortunately fast cars done come in manual these days.
@@BrosFOURRSpeed super cars are for flammers
@@mblake0420 what does that mean? People who work hard and want to use their own money on a car is their business!
