DSG Transmission - Explained

What is a DSG transmission? How does a direct shift gearbox work? A DSG transmission is a dual clutch transmission used by Volkswagen. A DSG uses two wet, multi-plate clutches to activate separate drive shafts which send torque via the even or odd gear sets. Because the gear sets are on separate shafts, this allows for preselecting the next gear, allowing for nearly instantaneous gearshifts without a total loss in torque. DSG tranmissions operate a lot like manual transmissions, but they are electronically controlled and thus the gear selection can be either automatic or manual, but does not require the use of a clutch pedal as this is all activated automatically.

Honestly I think I picked up a good portion of this surprisingly. Whenever people tried to explain how a manual trans works to me when I was younger, trying to learn stick, they honestly just confused me so much more than if they told me how to use the clutch and not explain how the transmission is actually working. However if I watched this video it would’ve made much more sense now.

The DSG is an amazing transmission. It’s one of the main reasons I bought a MKV GTI - I was so impressed by the technology. I enjoy driving manuals, but I think the DSG is fun to drive and it benefits from improved performance, fuel economy, and convenience over a traditional manual. VW is also continually improving it; I drove a 2013 GTI and the DSG was even smoother and more refined than my ‘08. Thanks for showing us the inner workings of the DSG!

So the fuel gets ignited, making the sound. The reason for the timing being cut is to prevent the engine from revving while the shift is occurring.

I used to have a Mark5 Golf GTI. Occassionally it would take 1-2 seconds to engage after putting my foot down after creeping forwards waiting to turn at lights. I think you nailed the explaination in that the conntrol unit was confused and expecting to down shift. The dealership had absolutely no idea! Also in sports mode the downshift from 3rd to 2nd was very harsh as it changed as a much higher RPM. Now drive a Renault Clio RS, which I think has a similar assembly

@combomaster99 3 жыл бұрын

looks like this one had the same problem as my dct box has currently. the synchromesh rings are worn out causing heavy grinding on the thin gears which are needed so the shifter rings can engage upon them. this problem is pretty common for dct transmissions because of the frequent need for oil change (every 60k km) which IS NOT specified by the manufacturer. If the mechanic over sees this and your driving style is on the sporty side the synchromesh rings will start to wear out way before you hit the 200k km. The brain of the gear box does not know if the synchro is worn so it shifts without giving enough time for the gears to line up which is something you can do with a manual box. thanks for the video this is exactly what i needed to see.

@@FDALl-ms5kg An engine is very simple. Have you seen a 2 stroke engine?. A 4 stroke engine can be made very simple too, if you look at 1920s engines they had very few components and complications. Modern engines are complex because they trade simplicity for efficiency. The higher efficiency you have, the harder it is to gain more efficiency, designs start to be cumbersone and many extra decisions have to be made to gain 0.X%. In engineering, when you want to calculate reliability you apply the formula R = e-λt. When you have multiple systems that need to work together, then you have Rs = R1xR2. In a DCT gearbox, the number of Ri(s) you have to multiply is very high. If there was no other physical solution to the problem, then it would be considered a complex but good or clever design, but because there are simpler alternatives that have less components, are more reliable, simpler to build and repair and have the same or more efficiency, the DCT can no longer be considered a complex but good solution, it's just a complex solution.

The other shaft handles the rest of the gears. And one clutch is connected to one shaft, which means that the purpose of this DGS is just wrong. What am I missing? :)

VW cars are notoriously famous for their DSG (dry clutch variant) & mechatronic problems in Asian countries, especially if the vehicle was heavily used in hot weather, traffic congestions & start-stop traffic (yes, our traffic jams are horrible). It has been circulating around that the dual clutch transmission is very jerky in start stop traffic & indecisive in choosing the right gear in those circumstances. as a result, DSG tend to kaput after 6 months of usage & unfortunately it is time consuming (waiting for the parts) & cost a bomb to repair. & the problems persists not long after that. Ford's powershift (also dual clutch) is sharing the same fate too...

nicely done guys great explanation. Scania and other truck manufacturers prooved this technology back in early 2000's and it takes a while for the costs to come down enough so the price sensitive consumers in the car market will pay for it. then it takes off and it gets mass produced. It is the same for most of the tech we see in cars today.... Common Rail Injection systems? Cummins PT system in 1954. MVT and Vtec ... Cummins again in the early 60's U used to work on all of that gear in the early 90's and it was great to finally see them all appear in the market place from 2,000 on!

Quick question. When in "D", and I am stopped at the traffic light. I assume the wet clutch is constantly in friction, right ? So it is better to select "N" for longer stops than say 10 seconds ? Or do these clutches fully disconnect when I am stopped but still in "D" ? Or does that depend on the model of car we are driving ?

@SilverZ233 8 жыл бұрын

I would assume so, only because it's recommended not to inch forward in a DCT doing so causes unnecessary clutch wear, generally that's caused by engaging or disengaging too slowly or too often which makes me think that the clutch is not engaged at a stop. Also i think the type of clutch used in a DCT does not allow for slip while in gear so if it didn't shift into neutral at a stop it would stall.

@Silberschleier 8 жыл бұрын

afaik it depends on the brake pressure you apply. If you press the pedal firmly the DCT should go into neutral.

@unbelievabubbledave 7 жыл бұрын

Very good question and something I have always wondered. I've been driving with a DSG for about three years now and always stop at the lights in D and hold it on the brake. I've assumed the car is intelligent enough to work it out (demonstrated by the mind-boggling level of engineering in this video).

@Ronald.Golleher 7 жыл бұрын

He does explain this in another video, 5 Things to Never Do in a Dual Clutch Transmission or something like that. If you're fully stopped, the clutches will disengage from the engine so they and the transmission are not rotating at all.

every non-manuel cars disconnect the clutch(es) while you are breaking. only not if you squeez the break pedal too little just to slow down the movement of car.

Love it when you guys collaborate on these explainers! When I bought my mk6 GTI I drove the dsg and manual back to back to decide which I liked more. Though the DSG felt like the future, was faster, better suited to fwd and could handle more power out of the box I still opted for manual (the bitchy manual of the gti nonetheless). I only regret my decision a little bit.

@2K_Unlimited Жыл бұрын

Great explanation all around. A more common preselection error would be gently accelerating to close the gap on a 2 lane road before reaching a passing zone. All indications to the computer are that the next higher gear will soon be more efficient at a higher speed. When you reach the passing zone, if traffic is clear, you step on the gas to use more power and shorten your passing time, best done in a lower gear. Also, I question the location of the gears as stated, you might check those. If 5th and 6th are run from the same shaft, there's no physical possibility of preselecting 6th. Honda claims on their DCT all even gears are separate from all odd gears to achieve the same effect. I have not looked at the DSG, but in an attempt to achieve the same task, it just doesn't make sense for any consecutive gears to use the same power shaft. Well, we hope there's a stop before reverse anyway, but not the others.

So basically its a manual transmission using an automatic transmissions clutch packs and pistons. With the combination it might last longer then both wear wise because you don't have to worry about all the clutch packs a normal automatic has or the clutch going out like a manual. Since it's all computer controlled, as long as the electronics hold up, it should have over 100,000 miles of life or 200,000+ maybe.

Can you explain why there is a distinct fart/burp when shifting with these transmissions?

@sw96 7 жыл бұрын

My guess would be the engine control unit changing the engine rpm to match the wheel speed for the new gear. I believe that often they use the ignition timing to cause the engine speed change (when shifting up gears) and that will give you an 'odd' exhaust note during the change.

what are your opinions on dual clutch transmissions? are they good/reliable?

@winemeer7383 7 жыл бұрын

Spawn223311 Transverse 6 speeds (wet clutch) are very good. Some early versions had problems with their mechatronic units, though they have been adressed and fixed. They are very strong boxes and this have been proved from the tuning scene. Stock clutches can handle huge amounts of torque if the box has been remaped. Gears are also pretty good for a 350nm rated gearbox. They can handle almost 750-800nm before giving up. Keep in mind though that they need to be serviced every 40k miles (fluids and filter) and this is really important for gearbox life. Later 7 speeds (dry clutch) are not so reliable.( Im not talking about ttrs/rs3 dq500 units, those are 7spd wet clutch and really good) They have some issues with their clutch packs and their mechatronic units (completely different from 6spd) seem to fail often. I really hope that vw has adressed the issues.
