- 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. My Nissan GT-R is equipped with a DCT and here are things you should not do if your car has a Dual Clutch Automatic Transmission!

You definitely forgot the most important tip: Never shift to drive from reverse white the vehicle is moving. 🤔 Try it - it will give you a nail biting grind!
Yea I would agree with that, come to a complete stop to do that.
That's pretty much on any transmission!
You don’t understand how many people I’ve seen switching to reverse and vise versa when parking etc. and still be in motion
You mean race mode,
@@betodlr749 not on a powerlide, c6 or th400
I think I’ve come across a couple of your videos and they have helped immensely! Thanks again!! Also love the interior 🫡
Oh nice! Glad to help. Yeah the red leather is so nice! Still smells new 50k miles later lol
Great video, thanks for the easy explanations :)
Glad it was helpful!
Subscribed! This was very helpful,. Thank you.
Thanks for the sub! Glad you enjoyed this video!
A lot of the info is GTR specific
BMW DCTs do not perform the same way
In manual mode the car will not creep forward, and on a hill with foot off brakes, it will actually roll forward/backwards depending on the incline/decline
You would have to tap the brakes to engage forward creep mode, it's essentialy in Neutral
bottom line is it acts just like a manual would unless you engage forward assist and or in gear
And even then I am not sure it is the right advice, at least for all. Porsche's PDK also starts creeping and there it is a "feature" that it will even start creeping on a slight uphill. Also, e.g. in the newer 911 turbo, it will actually slip between gears to save fuel.
Very well explained and demonstrated..
Glad you enjoyed it!
Dope video man, just got my first car and its a dual clutch so this helped out.
Glad it helped! Fun transmissions to use!
Which car did you get? Looking for a reasonably priced dual clutch
@@electric26Kia forte GT2 2023 comes with DCT, really fun car to drive
@@themapspaer4099heck yeah! I got me one too and I love it. Quick and fun to drive!
Your car has anti roll back feature, you need to push brake harder it will hold for a couple of seconds.
Very informative video. Just a suggestion/ question..... If u r stuck uphill in traffic, u shud use brake hold and shift to L gear so that only one clutch engages. U shud also not creep bumper to bumper but let some distance build yp and then move
You can't actually do that technically. If you leave the gear selector in what would be Drive, at a stop with your foot on the brake it will be in a neutral state till you take your foot of the brake. The odd clutch would be the only one engaging since 1st gear is the lowest it goes. But up hill in traffic I would avoid creeping and leave some distance in front.
Planning on getting a 2021 Kia Forte GT with a DCT tomorrow. Didn't know some of these things, now I'm informed 😎 thanks bro
Nice! That'll be a fun little car! Glad yo help with some good info
Get the manual bro it’s so much fun
@@Skipuh yeah, but I like the DCT version instead
@jamarkisdaniels4429 i have a 2016 veloster turbo dct & it sucks. Im at 133k miles and ive gone through 2 dct's and 3 flywheels. Im now getting code p073f & out of warranty which is the transmission failing again. I assume you got the 7-speed dry clutch?
useful, thank you
Glad it was helpful!
i agree ..... i have a 2012 gtr r35 and it good to know any hints and tips to keep in mind ...... thanks 👍👍👍
I never knew about the hill start issue. Makes sense. I drove a few VWs with DSG (Transporter, Golf) and they would rattle very loudly on hill starts and in wet conditions when there was a chance of wheel slipping. The weight and stress would cause the clutches to slip and I get that now.
I have a vw scirocco, and my car has hill assist. The clutch engages when the accelerate. I don't experience and vibrations either
Yep, It holds the brake pressure with the same force you previously pressed it.
@@timeformetoact6 ?
I just bought a 2014 Fiat 500L for pretty cheap. I've read so many threads about ppl blowing out the DCT in the car. Hopefully with this info I'll have better luck!
Oh wow. Hopefully it lasts you well! Glad to help!
4:00: In my manual car, if it's downhill, I just release the brake and let it roll for a bit. If the ending is off, I usually just stay below engine relight speed (STOP&START) so it stays off while I creep forward.
That’s fine.
This was really helpful, thanks .. pls share a video on how to use paddle shifters when driving up or downhill
Glad you enjoyed the video! You pretty much use them the same as on flat ground. up shift when you need to and downshift when you need to
Basically when ur driving uphill try to be in the lowest gear possible like around 3-4k rpms depending how much gas ur going to be using and when driving downhill its kind of the same just stay in a low gear so the car is engine braking or if u up shift to a high gear you'll feel like if the car is in neutral
@@Motorsports_3 I thought it would be better to use high gears to go uphill and still be around 3-4K rpm?
@@250tsar yeah could it just depends on the car u have. Like I have an e92 m3 so if I'm going up hill and am around 40mph I would be in 3rd gear or 2nd because I would be around 5k rpms because that's where u really feel the power in that car. If I were in 5th or 6th gear going up hill I would not have any torque to move the car fast or safely up hill.
How do you drive your car? Auto or with the paddle shifters?
I drive a Mazda3 skyactiv automatic, which is advertised as proprietary but is essentially a DCT. Is upshifting into higher gears during acceleration without taking my foot off the gas safe for the trans?
02:48 not all automatic will vibrates on idle ( you are right for Japanese cars) if you drove hyundai santa fe with 8-speed transmission it's completely quite silent you cant feel anything of vibration same thing to genesis.
I am not suprise if you complain about vibraation on Toytota, Honda, Nissan, Mitsubishi and Subaru they suffer from low quality in electric unlike Hyundai motor group they provide best electric quality in their cars.
Hi, this was a very informative video. Thanks.
Would I be correct if I believe it's okay to have a DCT vehicle towed by another vehicle in case of a breakdown?
Please advise.
Thanks
Rustom from Sri Lanka.
I guess you could use neutral, but this a car like this, a tow truck/flat bed would be the better way to go.
In neutral of course.
I meant to draw attention to the fact that one did not need to obtain a professional breakdown service in the event of a system failure.
Thanks
Brian... I think it's a manual transmission that's automatically shifted. I believe the official nomenclature is, semi-automatic manual.
Doug yeah technically that’s true. It is a manual but the computers do the actual work
Bros FOURR Speed manual has 1 clutch. So duct is kinds hybrid
The DPS6 however, isn't manual transmission. It is not an automatic transmission either. What DPS6 transmission truly is something completely unique. This revolutionary transmission is the result of Ford having such explosive diarrhea with the consistency of ravioli noodles in coagulated tomato paste with metal shavings, it has caused Ford to end production on most of their products. A remarkably innovative strategy by Ford to put the DPS6 in so many of their already poorly designed and poorly manufactured vehicles for so many years in an attempt to standardize their marketing scheme of bafflingly inflated prices and remarkably poor quality. Ford is a legend because of this, and will prove to be an incredible story of an innovative and progressive influence at the beginning of an automotive age as well as the innovative regression of their own era.

y'all are a bunch of noobs it's pronounced bulbasaur
@@vid2ification Yeeee them dct Ford Focus were shit
your car vibrates at full stops because alot of new cars not only disengage the transmission they also tend to run on less cylinders while at idle... My VW Jetta 1.4t actually runs on 2 cylinders at idle in gear or not until the vehicle reaches 1400rpm and also does so at certain cruising speeds to reduce fuel consumption which can cause a tad bit of vibration when this occurs. This is common place with newer vehicles with Direct port injection and its coded into the engine management im sure a tune can bypass or rectify that issue but at the cost of fuel consumption... Just a theory but highly plausible depending upon the vehicle...automakers are being forced to make cars consume less fuel due to clean air legislation and many automakers if they dont comply will be two sheets to the wind... Too long bending the will of OPEC, we could have had these same vehicle fuel consumption years ago... The carbureted civic was able to get 50+ miles a gallon in the 70'-80's but carmakers refused to adopt fuel savings when building engines for the kickbacks they got from OPEC and lobbyists... damn shame
With Bmw when you let off the brakes at a stop the car won’t move or engage gear until you press the gas then you feel it grab the clutch and the car starts off in manual mode which I like
guwop will I’ve noticed that in the M4. I like that touch. Reminds me of driving and old school single clutch car
Bros FOURR Speed sadly a lot people complain about it but I love it I hope bmw doesn’t change it
Yeah i like it that way
Coming from an automatic to a 2021 Elantra Nline, when I’m accelerating the car goes up a gear then down a gear when I’m trying to reach 80KMH, why is this happening? Should I be more hard with it? Thanks!
Got some questions if you have the time. I have a 2012 Veloster N/A with a DCT. I've been trying to find information about this question but I haven't found anything conclusively. Is it safe to spin a DCT car around? I used to take my Elantra spinning in parking lots after it would snow and never had an issue. I'm wondering if doing this will damage the DCT at all. When I first start out, similar to a manual there's a half second or so where the car rolls backwards and that doesn't damage the DCT like it would a torque converter. I'm wondering though if the computer is smart enough to disengage the transmission when it detects a spin or if it'll rip itself apart.
I know obviously the GTR and the Veloster aren't similar, but I'm just trying to get some basic info about if I can spin my V in the snow without the DCT tearing itself up.
I don't think you'd have an issue just having some fun. If you were just going full throttle abusing the car for a long duration, maybe. But a couple spins in the snow shouldn't do anything. I had some fun in the snow in the GTR. ruclips.net/video/HP8mdA68WmE/видео.html
Very nice video....
Also does the auto hold feature put more strain on the clutch as its holding the car until you accelerate off?
Auto hold normally just applies the brakes for you
My Ford Ecosport is a DCT. If I don't put the gear to N while in traffic, the temperature goes up. They recommended to put it in N while i'm on a stop light or traffic to prevent overheating which is true. I see the temperature goes up if I stay on D while on the brakes.
Oh wow. That's good you're able to see the temp tho and keep things at good temps
@@BrosFOURRSpeed I bought a head up display that shows battery voltage, temp, oil, and rpm. :D
clutches are disengaged when brakes are applied at a stop...but your throwout bearing is under pressure. Which is equivalent to holding your clutch pedal down at a stop light. Replacing those parts will require opening the transmission.
Yeah that would be a pain in the butt to have to replace
How does auto start stop and auto Hill hold affect the hill hold situation, can I hold the brake until the car auto turns off the engine and leave it there? Does the start stop mechanism also disengage the clutch/transmission?
If a car has the auto start stop. It'll shut the engine off at a stop. But once your foot comes off the brake it'll start back up. If the car has hill hold too that might be 50/50. My Supra has auto hill assist. But the engine will start back up if I take my foot of the brake. If it has the actual button for the brake hold, it might leave the engine off until you hit the gas pedal
I’m getting a new car soon and my dad said the dual clutch is completely manual. But with you saying there is a automatic mode, is it bad to drive in only automatic mode? Maybe I can learn to use the paddle shifters later (Jetta GLI DC)
A dual clutch is not considered a manual at all, you can drive in normal mode all day long, you never even have to use the paddles if you don't want to, it's an "automatic" as far as just using the gas and brake like another car. You have the option to use the paddles shifters as needed and it's the same as driving in auto, expect you can control the gear. It's just like driving an automatic, it's not a manual at all. It just has clutches in the transmission rather then a torque converter like a traditional automatic
Your first point I was confused do you mean don’t brake your car continuously while on an incline ? Does that also apply to declines ?
And if you have to park on incline, is it better to also use to parking brake ?
Basically when you park. Keep your foot on the brake when you put the transmission into park, then pull the Ebrake, then take your foot off the foot brake. Then shut it off. That way the weight of the car is actually on the Ebrake, not the transmission
Why it vibrates in 1st? Its got your biting point of the clutch. And you never put your foot on accelerator when shifting thats money shifts. As you brake/slow down match the wheel speed with correct gear for a flat road ie 1st equals 0-15 kmph 2nd equals 10-20,3rd equals 20-40,4th equals 40-60 and 60+ is top gear doesnt matter 5th or 6th. This enables you to use Your engine efficiently with proper power output.and be on a lower gear 1 then 2 in uphill if speed is maximum of 50 kmph or 3 if speed is maximum of 90 or 4th if speed is maximum of 140 anything more just use top gears. Never overtake on high gears its Ok to use 3rd in 110 kmph for overtaking only. As long as the tachometer stays in safe position such as 2/3000 less than redline.
Even my Genesis Coupe that had an automatic did that. So idk. In a DCT you need to keep your foot on the accelerator between shifts. This is not a manual tranmission.
Great tips tho
Hey. I know this video is a bit old now, but I am hoping you are still getting notifications. I am now in my first DSG (2020 Audi A3 quattro). When I am driving in Manual mode and coming to a stop, both options seem to cause the transmission trouble. Either I shift from 2nd to 1st at about 1000 rpm, or I come to a stop while still in 2nd. Either way, the transmission makes unhappy noises. Nothing really awful, just like it is confused. All of my cars have been manual before this, so for me shifting gears myself is important. Any advice on which one of these options is the best, meaning the least damaging? (note that in all automatic modes, it does not make these noises when it comes to a stop). Thanks for any advice you can send me.
It's probably because the car is wanting to downshift to 1st gear once you come to a complete stop. Seems like a lot of DCT cars are a bit weird if you manually shift to 1st gear while driving ;)
@@BrosFOURRSpeed Hi. Thank you for replying. Actually I believe I just figured it out. I'm used to driving a manual, so I would downshift to 2nd and lift my foot off the brake pedal for moment, then stop. I thought the car might be thinking when I lift my foot off the brake pedal that I am about to accelerate, so it gets ready for 3rd gear, then I stop, so it has to shift quickly from 3rd to 1st with one clutch. Now I don't down shift to 2nd, I just apply consistent brake pedal pressure and it shifts smoothly. Or, if I am in 2nd due to speed, once I begin to apply to brake pedal I keep slight pressure on it until I stop and it is ready for 1st when it needs it. Only took me 5 months to figure it out!
What about holding both paddles in at stop sign as that’s also a neutral as you can rev it with out moving.
It doesn't do that on the gtr, lambos and Ferraris do that.
Does the R35 come with "rev match" everytime you downshift? Like the ones you find in new Type R Civics?
Technically yes. A DCT is always going to have the next gear change happen as smooth as possible. So adjusting the engine along with the gear change is what they do
I have booked performance DCT vehicle, during bumper to bumper traffic if I use manual gear and use paddle shifter, will this also make engine hot?
That won't make a difference.
Does your car roll backwards on a steep hill after releasing the brake pedal? I have a Ford Fiesta with the 6 speed DCT and will roll backwards just like a regular manual does.
It depends. But the transmission will try and move it forward. But if theres too much resistance it'll roll back like its in neutral
I have a importaint question, about my 2020 gt500. I noticed when in manual mode when i down shift AND press the Throttle hard all at the same timing, its like "rev matching" a DCT transmisson and makes the revs go higher then just pressing the downshift paddle but my question is, is that safe for the DCT???
I wouldn't do that. The GT500 is already rev matching each downshift. But you're messing with the shift logic. When you're coasting or on the brakes, the next gear down is already engaged with it's clutch to be shifted into. So when you hit the gas and downshift, the car thinks the next gear will be one higher. So it'll be delayed a bit.
@@BrosFOURRSpeed ok thanks
I want to use an automatic FWD trans (which will be mated to a GM V6-60/mid engine set-up). Can anyone recommend a very strong FWD Auto trans to use?--(NOT a CVT trans)
That's be a hard one to think of. Maybe something from Toyota?
the steering wheel vibrates because of resonance frequency, in idle (not in all cars) the motor basically shakes the steering wheel at the frequency it would naturally vibrate at if you hit it, this makes it shake a lot more than when the motor is at any other rpm ie not shaking the steering wheel at the frequency it would naturally vibrate at
Very interesting explanation ;)
@@BrosFOURRSpeed thanks, hope i could help
When downshifting to go into a complete stop, is it necessary to go all the way down to gear 1 or is going to 2 and completely stoping okay too?
Reason I ask is because when I go to 1st it feels very clunky as opposed to when just stay in 2nd and stop fully. Thank I’m Advance!
Actually i had the same feeling from a complete stop. A clunk noise comes in my engine every time i accelerate from a stop and it feels weird though
@@Dann-md9eq that noise is the clutch engaging when you take off because the car is basically a hybrid between manual and automatic
1. 00:48 taking foot off brake on a hill.
2. 1:48 putting into nuetral at a stop light
3. 3:10 dont creep forward
4. 4:14 how you shift while braking or accelerating
5: 6:28 how you launch
Yup all the points covered ;)
@@BrosFOURRSpeedthx, my 1st car is going to be a dct. Hopefully it does survive like 10+ years 😂
Thanks, great tips!
Questio: What’s the ideal way to handle a DCT car in bumper-to-bumper traffic on an incline/hill? Is it ok to go to N or P and enable the handbrake/parking brake instead of remaining on D and keeping your foot on the brake pedal (which seems tiring for the right leg)?
You can do that if you want. I try and leave a bigger gap between the car in front of me. And then let off the brake and let the car roll with my foot off the break. That way the clutch is fully engaged and can just drive slow till I need to stop. Better then constantly hitting the brake
I'd say let your leg get the workout, as holding the brake pedal gives you a lot more control over your car both when it comes to starting to move and applying the right amount of pressure to hold still on a hill
I just bought a 2023 Changan Alsvin with a DCT, I live in Manila Philippines and the traffic here is the worst. I'm constant in bumper to bumper traffic. Dealership told me to put it l in N when I'm bumper to bumper traffic. What I do is put it in manual mode during heavy traffic and creep in manual mode. What do you think about that?
In my focus sometimes I wanna put it in park and put the e brake on, because if I let my foot off the brake on a hill it will roll back like a second later. 😅 I do always leave space like he mentioned though
@@sebyo7650 I just bought a vw with dsg transmission, as i learned from experience and suggestions, manual mode in prolonged traffic saves the dual clutch system,you are right
Cool. Still debating on the GT-R. I own M4 with manual trans . just pushing 510 to the wheels, and I get the itch for the GT-R. Love the m4 but think I should wait a bit as new GT-Rs gonna hit the market. So 2014s or 16s get cheaper.ish ?
DailyDrivenTurbo GTR’s have been holding their value. So don’t expect them to start dropping. But in the $60k range. You’ll be able to get a good one
@@BrosFOURRSpeed yep. There was one local for 49k. With 50k miles 2010. But I want 14 plus. And has to be in black. :)
DailyDrivenTurbo A 14 will definitely be in the 60 range. I paid 67, and even two years later, mine is still work about the same!
@@StreetDrivenDaily I'm actually flying in from Philly tomorrow to pick that one up for my channel.
@@theofficialrecojefferson noway lol.
When coming to a stop should I shift down to a lower gear like 3 to 2 then 1 or is is okay to just stay in 3 or second and?
You can leave it in 3rd. The car will automatically downshift anyways
In regards to shifting when in "manual" mode. Does shifting the slower way damage the vehicle?
Not at all. The car is designed to do this
Basically what's happening is that in a DCT, there are essentially 2 separate gearboxes, one that has the even gears and one that has the odd.
If you're in, for example, gear 3, only the odd gearbox would be engaged. This lets the computer preselect the next gear as the even gearbox is disengaged. If you're on the gas, the computer thinks you're gonna upshift so in this case, it would preselect gear 4 in the even gearbox. If you instead downshift, the computer has to first move the even gearbox from gear 4 to gear 2 and then shift, leading to the longer shift times. This happens in reverse for when you're on the brake.
I have a dual clutch Hyundai Kona and noticed that when I creep, it shakes quite a bit. Like jerking back and fourth as it goes to 1 and 2 mph when inching forward. Does that ever happen to you? Thank you for the informative video - I know now to leave space.. just wondering if you’ve ever experienced any shaking.
I have the exact same concern with my Hyundai Kona 2019. It jerks when in a stop and RPMs shoot up. Based on the comments and replies of OP it's normal for dual clutch to have that. Scares me a little though coz it's a different feeling
@@Dann-md9eq from what I have read, it is important to avoid letting the car crawl. So right after you take your foot off the break, you should begin to accelerate into first gear to keep the clutch from slipping. Disclaimer: don’t know much about cars.
Only problem I see with launching your car is if your at a traffic light, you would need to time the revving up with foot on the break right before light turns green as I imagine having it in that state of high revs while breaking for a long time (while waiting for light to turn green) is not healthy for any part of the car, or is it ok to do so?
Yeah if you were doing it at a light, you'll want to be cautious. From what I noticed the GTR times out after 5-10 seconds or so. I did a few drag races on the strip and I had it time out on my as I waited for the lights to go. So it'd kinda hard to time it with the tree.
gr8 video but will it hurt the trans if i shift then let off hard?
Not at all. Once it has shifted you're good to let off. I do that alot
when explaining your #1 thing you didnt give me a way to avoid not having the clutches have the load of the car while on a hill. i happen to have a duel clutch car an i tend to do this alot. thanks for your time.
Exp3rt45 As long as you keep your foot on the break on a hill. You’re good!
Do you accelerate as you release the brake (like in a manual trans; how release clutch and press on gas)?
Yeah i thought the same thing. Its ok to let your foot off the brake and press the gas pedal. Just dont use the gas pedal to keep you from rolling backwards. Use the brake and when you're ready to go press the gas pedal.
@@BrosFOURRSpeed can I use handbrake on uphill ? Thanks for your video. I just got my Kia Seltos with 7 Speed DCT. I need to really learn this DCT things
Let me start off saying this Ford redesigned the ford dual clutch transmissions for the Ford Focus and fiesta. Would these tips be the same for a 2012 Ford Focus dual clutch transmission
Could be. These tips are definitely very helpful with the GTR. But can be used for other DCT setups for sure!
@@BrosFOURRSpeed thank you! I had to replace the clutch last year so I wanted to be careful this time around. Plus me flooring it didn’t help lol
So I just got a dct. It’s in a Audi A5 sportback. I used to love to downshift my other Audi when making a pass on the freeway making it pretty fast grabbing up some lower torque. I think it had the 8 speed cvt. In this dct when I downshift it to make a pass it just takes a while to go into gear and it doesn’t feel like I’m grabbing any torque like the previous Audi I had. So how do you make a snappy pass with a dct?
I'm guessing you are on the gas while downshifting? Try downshifting while not on the gas or while on the brakes. It will shift quicker.
@@BrosFOURRSpeed definitely not on the gas while shifting..
But bro idk why some of the dual clutch car and some of the torque converter automatic when you activated the launch control they even don't say in the indicator that the launch control is ready I know that you can feel it but is much better to have a indicator that says launch control ready rather than feel it cause it's much easier to go than when you feel it
Yeah some cars just have it to where it says its ready. The GTR, You know if its working since the revs hold at 4k and the car doesnt move. Other cars if its not working you'll feel the car trying to search forward. Once you get used to doing launch control you can quickly tell if its working. If the GTR isnt warmed up it won't engage launch. And the RPM will stop at 2k and the car will feel like its trying to move.
Hi! I have a question. What if i put in manual mode in gear 1 and creep in heavy traffic. Will it wear my clutch or cause any overheating?
Ray Neo It’ll still wear the clutches. This car does a good job creeping in slow speeds. But do your best to stop, and then go a longer distance then ever foot. Or try rolling at the speed the car will travel in 1st gear with your foot off the brake. That way the trans is fully engaged.
@@BrosFOURRSpeed for my Hyundai Ioniq I get rewarded by creeping by having it charge the electric battery. I slow down approaching a stoplight a lot slower than I would otherwise do. Would this be bad on the transmission?
What should i look for if im buying a modified gtr?
Thinking about things that helps the reliability in the transmission, clutch and engine
Have a good performance shop take a look at the car and make sure everything is put together properly and check the tuning to see how it's running. After working at a dealership. The vast majority of modded cars that came in had many issues. I would always stick with buying a bone stock car.
Thx prob gonna go for a stock one then@@BrosFOURRSpeed
korvstopparen No problem! Probably your best bet
Yeah most of the time they sell modded cars for a reason unless they really need the money
Just got a new Hyundai Kona. When I drive slowly at mall car parks I feel a gentle tapping on the back. Is this normal?
Could be the clutches engaging. We had one for a week and it was pretty fun! ruclips.net/video/qq70nxzjZps/видео.html
Thank you. I learned a lot about DCTs. It's like having the best of both worlds. I have 3 cars on my list to choose from because I need a new car and they all have a DCT coincidentally.
Glad you liked the video! Cool transmissions to have!
@@BrosFOURRSpeed definitely. Our automotive progression is on full speed at the moment.
@@Mr.Deko86 for sure!
Can we shift to manual mode while the car speed is fast ? Or it should be done in slow speed ?
You can do that whenever you want!
Yeah this applies to everyone driving a gtr and Nissan cars with that same smart transmission's. I don't think it applies to all dual clutch transmissions but it has similar features even in my kia stinger. 😅🤣😂
But these things are good tips of what not to do in the dual clutch, they all fundamentally work the same. Some of these are geared towards the GTR of course, since that's the car I'm using.
@@BrosFOURRSpeed nahhhh
@@BrosFOURRSpeed i agree its still a dct.
Great video!!! Do y’all drive in cowboys boots?
You need to put the car in N at a stop light. If in the dash it shows 1 that means you are in gear and will wear the clutches
No you don't. The computer programing disengages the clutch during a stop. Thats why when you take your foot off the brake, you then feel the clutch reengage. So you can keep it in gear. If your foot is off the brake, the transmission will be engaged. So if your holding the brake, the car is effectively in N
What to do in slow - fast traffic , seems I’m confusing the DCT all the time
Just try and drive at a constant speed
we saw the stop sing :D
Can you time stamp what you are talking about?
DCT's problems w/stop and go traffic makes it a no bueno for daily driving for me. :( Bummer.
It’s definitely different! But my GTR has been my daily for 4 years! It’s manageable!
It preselects the next gear and disengages the current. So when the computer misses the preselection it is then that it shifts slower.
Yeah thats the cool thing with DCT
Have you guys thought about buying a project car after what happend to the z?
There was a title issue with the Z. So he sold it back to the dealer to avoid that headache. Eventually we'll do a real project car. But for now we'll focus on the current lineup and upcoming Corvette
Dont forget to get up to temprature on trans for launch
Absolutely! The GTR won't even let launch control active if its not all warmed up
I drop my brothers off everyday in a pickup line, this is about 10 start and stops in a row, so i just suffer? I try to give room to let the clutch fully engage each time i move yet still it is annoying.
Yeah that'd be annoying for sure
I have a question. Is there any problem if we coast with a DCT car? Or it will be good as it's providing regenerative braking?
There's no point to coast since it just disengages the clutch if you mean putting into neutral, and regenerative braking is only on electric cars for the most part and some hybrids.
@@BrosFOURRSpeed yes sir it's an hybrid vehicle but with DCT.
Firoz Ahmed Which hybrid car are you talking about that has a DCT? Also, regenerative braking has to do with the friction from the brakes charging a battery. Has nothing to do with the transmission 😉
@@BrosFOURRSpeed Honda Vezel Hybrid which has a Dual Clutch Transmission System and quite often this DCT gear box is affected because of the driving error. That's why I wanted to clarify the engine braking or coasting issue by Honda Vezel. Thanks a lot again.
your car viberates because of the transmission oil films inbetween the 2 sets of clutch disks, it transfers a little bit power, that being said , it's still a lot much lower than the AT torque converter.
Interesting
@@BrosFOURRSpeed i dont know about if it appears on dry dual clutches, in a wet dual clutch car, it is call prepressing when u put the shifter at D while not moving the car. of course it totally disengages the 2 packs of clutch disks when the car is neutual. actually it's why wet clutch one lasts far more longer than its counterpart. the gist of it is the transmission oil films cover the friction surfaces to reduce the most of the wearing
@@ashbringervindicator yeah I can see that. I can adjust the touch points with my Cobb tuner so lessen how much it does that. So it’s cool I can at least do that
In a DSG - when coming to a full stop from a high gear does it downshift automatically? I own a manual and when I'm coming to a stop I throw it in neutral so just wondering how it works if I buy a DSG? Thanks.
Yeah any automated gearbox will automatically downshift at very slow speeds. Once you get to around 20 mph, it'll be in 3rd gear and then almost at a stop it goes to 1st
Had my kia for a year and half now and never knew somethings you were talking about, thanks for the video really informative.
I noticed the shaking on mine recently more then before especially when creeping in traffic or when I first start the car and reverse it then put it in gear
Glad you enjoyed it! DCT cars are a bit different to get used too then torque converters
So you discussed creeping forward a foot here, a foot there.
But what about creeping for long distances? For example, in a car with an automatic or CVT, I tend to creep through parking lots. I take my foot off both pedals and I hover my foot over the brake in case someone suddenly jumps out from between two cars, or in case a parked car suddenly pulls out. So I'll coast through the entire parking lot with neither brake nor accelerator engaged.
And I do the same thing in my driveway. I have a long, narrow driveway that is walled in by my house and a fence. It is just barely wide enough for a car to fit without scraping the house or the fence, so I'll go through the driveway slowly by creeping, with my foot off the accelerator, and just hovering over the brake.
Can I do that with a DCT, or will that damage the DCT?
Thats no problem. That's not actually 'creeping'. Thats just letting the clutch engage and letting it properly work at its slowest speed. No issue. Creeping is more of on and off the break. So the clutch will be constantly disengaging and reengaging. So you'll be good!
@@BrosFOURRSpeed Thanks!!!
No problem!
So the last few times I've driven, I've been paying more attention to how I use to brake to see if I've ever been brake creeping.
And I realized that while I almost never brake creep in traffic, I do seem to brake creep a lot in reverse. My driveway is extremely long and narrow, and it's bounded on either send by my house and a fence, so the idle reverse speed is too fast to safely navigate it.
Instead, to travel down my driveway, I've noticed I've been lightly depressing the brake so that the car reverses slowly rather than at full speed.
How bad would this be for a DCT? Is brake creeping bad in reverse too?
And if it is bad, is there another way to reverse more slowly than the idle reverse speed?
So you can drive a corvette c8 like any other automatic car?
The Corvette C8 does have a dual clutch so you would drive it a little different than any regular automatic. It's essentially the same thing, but does react different. The tips I gave in this video would help with some things not to do or to help prolong the clutch life over a normal auto!
I wish I watched these videos before I broke my DCT clutch transmission.
ouch.. Hopefully it wasn't too expensive to fix!
I have a question, my GTS ( i30 N ) has the 7 speed dct and first gear almost feels slippy in general in Normal Mode. Like, it doesn't feel like it fully engages, and then shifts up under 2.5krpm into 2nd. Is this a normal characteristic for a dct? Am I not letting the computer engage the clutch correctly?
Hmm, do the RPM jump at all while accelerating in 1st gear? If they stay smoothly increasing then it might just be how it feels then
What Gts?
My GTR has a rough downshift from 3rd to 2nd when I let car downshift. I can feel the car jerk most of the time. Anyone have this problem? Also, since the car has shift-logic and shifts slower when you gas and down-shift, the best way to get to a lower gear and accelerate is to brake and down-shift?
idk why yours would be jerky. But if your on the brakes it'll downshift quicker. ON the gas pedal it will be delayed if you downshift.
it could just be the shifting down when at higher revs, combined with not being braking so it isn't lining up 2nd? This can happen in my Golf R32 as well.
Dct relearn
My car has a dual-clutch transmission. Let's say I'm driving, and I suddenly decide to take my foot off the gas pedal. The car goes from 5th gear to 4th, then to 3rd, 2nd, and finally down to 1st gear. Does this put strain on my transmission? I feel that from 5th to 2nd gear, everything is alright, but when it goes from 2nd to 1st, the feeling is a little strange.
If it's in automatic doing that. It's perfectly fine since its programmed to do that. You can downshift to 1st. Just doing do it at fast speeds
why on the mannual still auto down shift means that is semi mannual though, am I correct ?
It will only downshift when you get very slow. Slow enough to where the car could stall in such a low RPM.
@BrosFOURRSpeed tks Bro, but upshift still need to be controlled by the shifting plate.
So when put in manual mode, you dont need to let go off the gas when switching gears?
Nope! DCT transmissions dont need that since the other clutch is already engaged. The computer takes care of any throttle cut needed
@@BrosFOURRSpeed and i dont need to press the lever when doing that either right? Only when changing from d-n-r-p?. Got a new golf 7 so im not familiar exactly since this is my first automatic
Hey, I have a question. Is it fine when you down shift, you feel the car not really jerk but force slow. If you know what I mean ? Also I never shift down to 1st unless I'm going real slow or coming down to a stop. Is it okay to shift down to first while going like 30mph? Cause I don't think so?
That might sound like you are downshifting while going too fast. I wouldn't downshift to 1st while going 30, you really only use 1st to get started, so 2nd would be fine at 30mph. The downshifts should feel smooth if you are going the right speed! Hope that helps! What kind of car do you drive?
@@BrosFOURRSpeed yes I know this aswell. However even at 10mph it'll feel like I'm using the transmission to slow down.
@@BrosFOURRSpeed it has happened to me with most dct cars I drive
@@BrosFOURRSpeed also it's okay to shift up without lifting right? Because I don't lift.
@@lameass8899 Hmm, at 10mph you should be on the brakes still maybe, but even going to 2nd is fine.
I’ve driven an automatic car for ten years it suddenly started jerking off and I took it back to the dealership turned out it needed a software update no more jerking.
Oh interesting. Glad you got that squared away!
Is it bad to put the car in N while driving to Give it a little rev?
Not at all. Just make sure its back to about idle before putting it back in gear
during traffic signal or any halt, should i allow the car to be in D or P mode with brakes pressed? I am new to dsg, can u clarify
You can leave the vehicle in gear and just stay on the brake, that’s not the issue.
The issue is stop and go traffic and slowly inching forward as soon as the car in front moves.
You can minimize that by allowing them to move farther in front and then when the gap is big enough move up so the clutch has time to fully engage.
Curretnly I @@BrosFOURRSpeed
@@BrosFOURRSpeedthanks for the reply. i Put to P and hold brake now for more than 15 seconds or d and hold brake (full or half?) and move. Kindly advise.
@bros fourr speed
I’m really into GTRs and my budget is just possible for a 2009 gtr that has 59kms. It’s in good condition. What’s the most important things I should check out for please?
Youll want to do a tune on the transmission for that year for sure. Thats really the biggest issue. Get a Cobb Accessport with TCM. However my GTR is for sale if you want it ;)
@@BrosFOURRSpeed what state and how much are you selling it for?
I'm a first time driver passed on automatic, can I drive dual clutch without a struggle ?
Im interested in an alpha romeo giuletta 2012 which has twin clutch
Yeah it shouldn't be much different from a normal auto
@@BrosFOURRSpeed thank you 🙏🙏
Can anyone tell that how a wet DCT responds while moving down hill for a longer time while bolding brakes. Will it disengage the clutch and set the car free or will it continue to provide engine braking downhill?
I want to say the clutches will stay engaged the whole time. But you can feel it let the car coast. I think depending on the speed you're going it'll re engage to engine brake and hold a speed close to what you're going. But it will let you coast a bit
You can watch the tachometer, if the car has one. If the revs stay around normal cruising speed, the clutch is engaged and provides engine braking. If it goes down to idle speed, its disengaged.
In manual mode you will get engine braking like a manual box . The DCT has two concentric clutches only one is engaged at any given time one clutch controls the odd number gears one does the even number gears one clutch is ALWAYS engaged a computer predicts what gear you will need next and preselects the gear so when the computer shift to the next gear it does so very rapidly , less than a tenth of a second . In auto the hill decent is controlled by you braking just like an automatic transmission. In manual mode it behaves like a manual transmission if you downshift with the paddles the lower gear will slow the vehicle augmented by useing the brakes.
I have a Kia Forte GT with the dct. When I have the shifter in manual mode and upshift early under hard acceleration it has massive wheelspin on the upshift. When it upshifts on auto mode it never spins. Does this happen to anyone else that drives a dual clutch front drive car?
Maybe you're shifting right as the full boost kicks in? A car like that will have more torque down low then it does top end HP. So that could be it
Exactly what he said shift before 3k if ur cruising turbos rpm 3k-4 45k hp rpm is 5k-6k so ur shifing as the turbo is spinning ride it out until 4k or 5k shift for DCT
I have a 2017 Ford Focus S with DCT Whenever I'm going 40 or 50mph and I press the gas it takes a good sec to pick up and when it does it goes stupid mode from 3krmp to 5500rpm is that normal?
Sometimes it redlines
That's just the car downshifting to a better gear when you floor it. In automatic mode it'll always go to redline to shift if you are flooring it
@@BrosFOURRSpeed honestly i turned off traction control and it handles and accelerates better
DO put it in neutral while at a stop for a long time. When you are stopped the transmission stays in 1st year ready to roll and holding the clutch ready for when you let off the brake. If you put it in neutral it takes it out of gear and releases the clutch so it’s not holding it. The module/actuators the engage/disengage the clutches are no longer working if it’s in neutral so they dont keep heating up.
Sometimes I'll put in in neutral just so it idles smoother. It's designed to be able to be left in gear. So I'll do either
I like cars but don't know much. Anyway when using the paddle shifters do you u still push the clutch in or dose the car do its self
There is no clutch peddle in a paddle shift car. That is automated for them.
Very nice video btw. I have a Honda Accord with paddle shifters and I tend to downshift to 2nd gear a lot so I can accelerate faster but I don’t know if this is bad for the engine or transmission. Anyone know?
Nothing wrong with that. Most likely thats a torque converter automatic. Not a dual clutch auto. As long as you're not downshifting to a low enough gear where your bouncing off the rev limiter, I wouldn't worry about it
@@BrosFOURRSpeed thanks man really appreciate it!
@@illuminate6606 i have a camry with cvt that has a “manual” mode, I find that the if I tried to shift into a lower gear that is too low and could possibly over rev the engine, the car won’t actually let me downshift and let off a warning beep. I imagine that the your accord also has a cvt since I don’t know of any accords with a dual clutch. And because of that, if the car lets you downshift, that gear is not low enough to do any damage to the car, so you should be good.
This isn't bad; however, it will cause you to use more gas because more power is being delivered to your wheels.
Can you go over Stopping in a DC? I just got a GTI and it freaks me out when i slow down to a stop and it lurches... I hope I'm not breaking it :((((
You just stop like normal. You may feel some gear changes in slow speeds. But if it feels very weird, may want someone to double check it with you
The fact that when you shift from Neutral to Drive (1st) and your rpms drop is indicating the engine is working harder... due to very slight clutch drag. To say otherwise is ignorant. The RPMS drop for a reason, and you need to explain what that reason is. and the reason is the clutch plates are slipping, even though there is no forward motion. To demonstrate, put your car up in the air and put the car in "Drive" with the brakes off, and observe if the wheels start spinning. If they start spinning the clutch is dragging, putting pressure on the flywheel and spinning the whole driveline. If the wheels are spinning, then the clutch is dragging on the flywheel at idle while in "Drive" mode.
Yeah obviously the wheels will spin with your foot off the break. The GTR and most other cars have a sensor to where when the brake is on, the clutches are disengaged. Once you let off the brake it engages the clutch
@@BrosFOURRSpeed Explain the rpm drop, then, from neutral to drive, when the brakes are on in both gear selector positions
what is the point of the bottom left camera from 4:34
I think that was the only way I was able to split the screen, so I had to throw that in to make it work..
Could be bad motor mounts cause the idle vibration
Not a bad point. Never thought of that. I'll take a look at them
I love how on my M5 it stay disengaged unless I tap the gas
Is that the single clutch M5? I think most DCT's will do that. Just when you let off the brake thats when they engage.
@@BrosFOURRSpeed Mines the f10 so it uses the DCT, all M DCTs won't engage unless you tap the gas, which sucks when you park on a hill cause it rolls.
Well, looks to me like you treat DCT, PDK, etc. dual clutch transmissions with the same sense and logic as you would a regular manual transmission and clutch.
Pretty much! Just have to be conscious about the clutches engaging
Biggest question I have, I’ve never driven a manual but my Veloster NAV has a dual clutch transmission, and I’m pretty good at shifting up gears, however how do I “properly” shift down gears? Every time I’m driving it manual mode I try shifting down a gear getting close to other cars on the freeway or getting close to a red light / stop sign but then the Rpms shoot up like CRAZY and it kind of freaks me out so I put it back to auto until I start driving again then I go back to the manual mode
The RPMs shoot up because you downshifted early. It won't hurt anything as long as the RPMs don't hit the red line (since it is a DCT though, it should have downshift protection which would prevent you from downshifting too early and damaging the transmission). RPMs will always increase in a downshift but if you don't want the RPMs to increase much in downshifts, then slow down more before you change gears. The sooner you downshift the higher the RPMs will raise. You can slow the car down some by downshifting early like that though. If the RPMs get near 3,000 or higher it should have quite a bit of engine braking happening which is useful when going down big steep hills as you don't have to use the brake as much.
You really don't need to downshift going to a stop light. But if you want to just to hear the engine or have more fun thats perfectly fine. As long as your not always hitting the rev limiter its all good!
Hey bradley. I have the same concern with my dual clutch Kona 2019. The RPMs just shoot up from a stop then goes back normally. The mechanic told me it's normal to jerk because it's dual clutch. I don't know if it's true but good thing I am not the only one who noticed it
@@BrosFOURRSpeed You don't have to downshift when approaching a stop light; However I believe this is the proper way because it allows you to decelerate faster and remain at the correct gear in emergency situations. Study how and when the ECU shifts in Auto mode; My DSG usually downshifts at no higher than 2000 RPM.
1:08, here how come you had the foot off the break yet it did not move forward?
I believe I explained that in the video at that time. I was on a hill. DCT dont just start driving when you take your foot off the brake. I had to apply some throttle to engage the clutches fully. Flat ground the car would move. But not on a hill
@@BrosFOURRSpeed Much obliged.
@@BrosFOURRSpeed I saw a car that has D and 3 2 1. Can you make a vıdeo where you explain when to use the 1, 2, ans 3?
