- 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.

NEW VIDEO EVERY WEDNESDAY! - Auta a dopravní prostředky
Thanks for having me on the video and hanging out at the garage. :)
Always a pleasure dealing with the elderly.
Engineering Explained what's that sonny....
Excellent "explainer" video guys. Thx.
HumbleMechanic Would you ever do a video discussing the effects and pros cons of a dsg tune??
I see a lot of CO brewery stickers on the toolbox. Are you here in the state?
Hurts my brain trying to understand is wizardry, the designers of this are incredible
They are called engineers. If you like the idea, look into "machine design" in engineering, and engineering school is awesome :)
There's a video explanation of ZF 8HP on WeberAuto channel. Check it out
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.
same here bruhhh xD xD
The cost to maintain one also incredible
This is probably one of the best demonstrations of a VW DSG transmission I've seen yet on CZcams.
Now we need triple clutch transmissions that preselect one higher gear and one lower.
What about a penta clutch engine where every gear has its own clutch
zeroangelmk1 What about a car with one engine for every gear
Honda apparently built a prototype 11 speed triple clutch gearbox. Though they've only put a 9 speed DCT and a conventional 10 speed auto into production.
Alex K. Lmao that would be wild!
@@zeroangelmk1That's already been done, it's called an "automatic transmission".
I had a a vague idea how the double clutch in a DSG worked but had no idea it was a shaft inside a shaft. Awesome video. Now that I understand exactly how it works I can see why my DSG shifts slightly slower in unpredictable situations.
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!
ferme ta gueule
Can I just say a massive thank you for helping me out with my college transmissions essay. Really couldn't understand it before!
I am amazed at how well you explained that! I have always had a vague explanation from others, and as an engineer it always bugged me. Great explanation, and having one to SHOW was amazing.
As always, a simple and efficient presentation of a comparatively complex engineering solution. Keep up the good work!
Thank for this amazing video. I love the way you explained the transmission with an actual unit.
Also great vid! I really wanted a detailed but easy to follow explanation of the DSG for the longest time. Thanks!
What a video!! I'm a mechanical engineering student and I love your videos, I can practically see what I'm studying and I can really learn the amazing world of automobile step-by-step! This video is not so recent but I've discoverd your channel since few weeks, damn! I will absolutely continue to watch you!
You should do a video on the fabled CVT transmission. Loved the video btw!
Great video! You guys seemed to flow well with each other. Very clearly explained. I got the gist of it. Thanks again.
The absolute best explanation and "class" I've ever seen on any component of a vehicles drive train... Thanks for putting this together for us folks who like to know this kind of stuff
Fantastic video guys! I always had a general idea on how the DSG worked but now it makes way more sense.
Hat off to the engineers that designed them and the mechanics that understand them.
and the people who drive them. hat's off, and passed to them, coz they're driving. I'm just chilling in the back seat
I really enjoyed this video, it has two of my favorite youtube hosts (Y)
Appreciate it! Charles is a rad man.
+Engineering Explained ---Ok so I get DSG, I have a 2014 gti drivers edition and..... what causes DSG farts. I had my resonator deleted today, basically so I could just have a deeper sound, and it does sound really nice, but can now hear the farts more. thanks
As has long been explained by lot of people, that is how it works, there are very funny videos on youtube about DSG and farting minions, check them out, and deal with it.
What is the actual cause of the dsg fart?
@@mbulelomankonkwana8038 First, the ECU cuts timing during the shift, but fuel delivery continues for a brief moment. So, some unburnt fuel makes it into the exhaust, which is hot. 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 really liked how you half- built a DSG to allow for a very clear and easy to understand visual of how the system works :) This allowed me to help explain how a DCT transmission works and why he was greeted with hesitation
*You are absolutely right Mr Charls, DSG shift way faster with* with quicker response than AT system.
Wow! Amazing. I knew in theory how it works but it's fantastic to see the internal components. Such a complicated piece of engineering. Hat off to the engineers that came up with it.
Thanks for the video... My car have a DSG7 and it s great, so great I barely miss my old manual impreza
Best explanation of a DSG I have ever seen. Thanks!
Excellent video, you guys did a great job of explaining a complex system in terms that are easy to understand. Well for me at least. I have previously read the expression of the dual clutch gearbox in the R35 Skyline to being like 2 gearboxes in one, I now see why they would think that.
Charles is awesome! Jason I liked this duo explanation! Great work! =)
Keep up the good work!...Very informative for us "shade-tree mechanics".As a side note: It'll be a dark day when the fully manual (meaning manual, old-school clutch) transmission is no longer available. I suspect those days are not too far away with the dual clutch transmission getting better gas mileage.
@@willheheckaslike8315 Note: Electric Vehicles do not/will not have manual transmissions, niether do the current Hybrids. I am aware there are a lot of those vehicles already in Europe.
(Full disclosure, I own 5 cars with manual transmissions, and two trucks with automatics. The automatic is superior for trucks)
@@willheheckaslike8315 Also, good luck getting a new Ferrari with a manual transmission.
This is a very good explanation. I just bought a 2014 Jetta TDI with this transmission. It takes a bit of practice to drive it smoothly, but it does work.

Started learning about transmission systems today in college. This was useful
Thanks for the video. It really gives us an overview of how this transmission works. I`m from Brazil, and I`m a big fan of you guys.
Nice job tag-teaming and explaining the DSG. As one with auto and manual trans experience in a previous life, everthing made perfect sense! :D I WAS disappointed not to see a duet from you two as an encore! ;-)
Great and fascinating stuff, guys. I've been wondering what the inside of my DSG looks like. My commuter is a 2014 Jetta TDI named Loretta and I couldn't be happier with her so far. However, every so often I do manage to somehow confuse the gearbox slightly and I get that pause in action that was mentioned. No biggie, though. I'll gladly take my 47 mpg highway and the awesome factory Fender sound system (actually Panasonic) and rock out.
5 L/100km on the highway is not even good for a diesel car.

Great explanation guys. My wife just got a car with a dual clutch transmission and I wanted her to be cognisant of the proper way to drive the thing and why. The whole thing will certainly be over her head but it will help a lot when I try to explain the computer's anticipated next gear and how she should think about driving correctly.
thanks guys! was experiencing that "jerky" behavior every now and then and this provided a great explanation for what's going on in the engine when that happens.
Love the DSG in my S3...so smooth and quick, yet had some of the same quirkyness of a manual (bite on initial pull off).
Joe Joe love mine too in S3 2016
Great collaboration guys. I love it when CZcamsrs get together on their own. I know it's not as easy as just recording your regular show. There is so much to tackle. Just know that there are people like me who see deeper than just the surface. (which was nicely polished btw)
Thanks for sharing
I have never in my life seen a more beautifully explained video thanks guys
That was super informative, as usual. Thanks!
Ah, so it's not actually faster changing gear, as in actuality, the gear is ALREADY changed, and all you're really doing is swapping which clutch you're using!
...Right?
Gara Von Hoiwkenzoiber Correct!
The Direct Shyamalan Gearbox.... you were in 3rd the whole time....
Yeah but you have only 2 clutches,and 6 gears. I think clutches are working when you are changing the gear. As they said its like manual transmission just it works automatically. For example. You have one clutch for speeds 1,3 and 5,and another one for 2,4 and 6. Correct me if I'm wrong.
It actually is changing the gear faster. Because you don’t change a gear until it’s actually engaged.
@@EngineeringExplained I've seen claims of shifts as fast as 8ms. Any comment on that?
Thank you Engineering Explained
I appreciate the video you had made earlier with the dual clutch
And now a better understanding video.I am only 16 and i know almost everything about how car works
Because of you. Its so much better than watching illegal car races
Salute to you Jason from Engineering Explained and Charles !!!!!
Jeremy Yeo Very welcome, glad you enjoy the videos!
Jeremy Yeo Thanks man!!!!
thanks for disassembling the transmission.
Always wanted to know how the hollow shaft looks like.
This shaft has to take a lot of force. Is it extra treated ? Better hardening process, another steel, or so?
I love your channel! I have learned more about cars in the couple weeks I've been following EE than in the decade prior. This video was awesome transmissions are beautiful.
Hey guys j know this video is old. But I just bought my first dsg car and I have been having problems at traffic lights. I just wanted to say this video helped me understand what I have alot better. Thank you guys for doing this
Superb, Simple explanations. Wonder why all technical videos could be this much simpler.
Nice video, been wondering how these worked actually inside the box. I'd really like to know the reliability of these boxes and clutches and what kind of mileage you'd expect compared to normal manual dry clutch setup? As I can only imagine the $$$ to fix/replace
Thank you for making such a great video. I was always wondering why my DSG transmission sometimes jerks especially when I’m down shifting from 3 to 1. Also the example you mentioned were with the red light and suddenly becomes yellow and green where it actually doesn’t want you to move as you actually wanted to, I thought that was actually a transmission failure in my car but apparently it isn’t so thank you very much for the video.
Probably need to change the clutches or recalibrate them to extend the lifetime a bit.
Recently got a 17 GLI with dsg and really love it despite it being the first auto I've ever owned. Seeing how it all actually works really makes me love this car even more
It's even more interesting than I thought it was.
Good Job Guys, I had my trainee's subscribe to your page to help them grasp some of these topics. I think I meet Jason at SEMA in 2013 with a N54 crazy looking Twin turbo setup. Hows everything going?
Escondido German Auto Thanks for sharing the videos. I've never been to SEMA, though I'd love to!
This is crazy mechanical marvel. So much knowledge and ingenuity was put into this DSG transmisson.
I agree
this is einstein-level?
it's really neat to see how all these things work, love these kind of videos.
Finally I get it
. I've seen other explanations but now I get it
My girlfriend walked in and said “oh look it’s the Rhett and Link of cars” and I died lmao. You guys make a great team haha
Great explanation! Clear, great demo , good to see all the parts.Thank you
Fantastic review. I've been considering getting a '24 Tiguan, but I've heard and seen so many YT videos that talk about the problems with DCTs that I'm really hesitant about buying a car with one in it. This gives me much more confidence in them. Thanks. Happy Holidays and Happy New Year!
Very interesting. I like it. But you'll never change my mind on a conventional manual transmission. I just love the feel of a clutch pedal under my left foot and a shift knob in my right hand. "If it feels good do it!!"
Joseph Inman I don't think you'll hear any resistance from Charles or myself. We both love our manuals.
Engineering Explained Definitely can't beat a clutch pedal and a manual gearbox.
it's a Doppelkupplungsgetriebe. You are welcome.
Well DSG is in German Direktschaltgetriebe, but yes, it is a doppelkupplungsgetriebe also ^^
Nicktrance1 Correct :)
+Max Power D-o-p-p-e-l-k-u-p-p-l-u-n-g-s-g-e-t-r-i-e-b-e
Which is why the clutches are called K1 and K2, probably: K for Kupplung, German for clutch.
both are the same!
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
You have gotten so damn good at this. Congrats. Very well done.
This is genius, I always wonder how did they invent such great mechanical parts!
They are Germans lol. The epitome of knowledge of engineering, match etcc. Look at Albert Einstein
Complex is the opposite of great engineering design
@@ALIENdrifter66 How exactly is complexity bad? If its convoluted sure. And engine is very complex, dont suppose youd call the genius who came up with them a bad engineer would you?
@@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.
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...
Mohd. Radzli Rahman I have been using a DSG Polo GT for more than a year now!!!!!!! Fantastic is all I can say!!!
And yes, it is being used in India in extreme hot weather of North India too! No problems felt!
@@brioown i have a 2011 golf tsi. It suffers the clutch slip and it can't engage in any gears
Used to work at a cab company in London, VW DSGs were good to about 150k miles and the powershifts on Ford Galaxies were about 110k
Perhaps what they should make is a triple clutch system lol
Thank you as I had no clue what '11spd DSG' meant on an an auction site I was looking at!
The best DSG transmission video I have seen, puts everything into perspective
When gear lever is moved to the park mode, what actions happen inside the box? Does it lock the output shaft?
There's a gear on the output shaft and the transmission sticks a pawl (piece of metal) in it.
Little gearbox fairies come out the woodwork to throw a small anchor. When you select D, the fairies go back in their box.
humor and engineering both combined. great video. thanks guys
Thanks :)

Fantastic video! Really made it easy to understand. And thank you for explaining what happens if you go against the logic of the computer, that question was in my mind during the video and I was very happy to see it explained.
Keep in mind the transmission is expecting to go up or down one gear at a time, so the alternate shaft will get the torque smoothly. But if you give a contradictory input, it now has to jump 2 gears up or down, the first one just to cancel the current pre-select. The alternate shaft is bypassed and everything flows thru the current selected shaft, so the change is going to be much more abrupt and harder on the clutches.
Brilliant, two gearboxes in one with concentric shafts.., so compact,
Thanks for the explanation
Could you explain the engineering decision to use gears that have angled teeth vs gears that have perpendicular teeth (similar to lego gears, for lack of a better visual example)
+Matkat Music helical gears are significantly quieter, thus far more common (but more expensive). Straight cut gears are cost effective, but very loud, so typically only used in motorsport, or for reverse gears.
Very cool. We need a video showing how the valve bodies for Automatic Transmissions work. I don't think your channel does animation videos tho...
Ever watch world rally racing? That is what straight cut gears sound like.
yes straight cut gears have a distinct whining sound... almost like a supercharger if you will. you can really hear them in a Honda while they are in reverse
True, WRC are mostly strait cut- and sure adds awesomeness to in car audio :)
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.
Just don't bottom wash your car
you would think.....
Hahahahahahahahahaha longer life than a manual
I just got a DSG car (ford fiesta) and have driven a 5-speed manual for many years. I heard a lot of complaints about the dual-clutch being jerky and not good at low speeds, but I've driven this 'new' car like I would have driven a stick, and it's not given me much problems. The clunky sounds it makes always makes me cringe, but this video really helps explain how my transmission is working. I've heard "it's a manual that shifts automatically" but this really gave me insight as to what that actually means.
Thanks!
Super cool video, convinced me that progress has happened and made me consider giving up the clutch pedal.
loving this guys beard.
astonfan188 awe, thanks :)
HumbleMechanic Thanks for making this video, I'm doing a college essay on the Volkswagen DSG gearbox and I found this video explained to me how it works :)
would a triple clutch fix the problem of which gear to preselect?
you"d have 1, 4, (7); 2, 5, (8); 3, 6
so no matter which gear you are in, it can preselect both gears next to it
AnarchistMetalhead Yes,that’s why honda is building it
Wouldn't you need three shafts then? Can't select two different ration gears on the same shaft.
Well, you could, but you'd regret it.
Outstanding guys, I actually understood that. I have the S-Tronic box in my audi a5 3.0tdi quattro and its a fantastic piece of engineering, such a joy to drive.
Thank you guys for the hard work. my understanding is slowly getting better and better. keep up the good work.
I like my DSG in my GTI. I have an engine and DSG tune and it's even better than stock. I miss driving manual, but the DSG is a great all around performer.
What so you4 dsg transmission is automatic
Charles has one epic beard
MrTURBOJOHN Thanks :)

Jacob Shields OrangeFiero
COOL!!!
2013 MK6 GLI with DSG fell in love on the test drive
Can you explain why there is a distinct fart/burp when shifting with these transmissions?
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.
you should mak e video of DSG vs CVT , or maybe you have already done and I havent found it yet
CVT = Crap Vehicle Transmission. DSG = Dank Semi-usable Gearbox. There ya go.
Marek Sumguy Still better than any transmission ever to come from The Retarded States of Obesity. :P
nelizmastr
Completely different technologies but I can say that CVT is usualy more responsive and more fun in the traffic. On the other hand DSG is more fuel efficient
lol. what? both of your statements are completely backward
Excellent job explaining the process, and thanks for the demonstration. Cheers!
I love the mechanic/engineer undertones of these videos.
I know there were a lot of problems with those DSG6 and DSG7 gearboxes. Especially in VAG cars till 2012 year. They also have extended warranty for 5 years on DSG only due to problems.
Do you know if in the cars with production date 2013 a newer there are still same problems or VAG already fixed them?
p.s VAG - Volkswagen Automotive Group if someone not familiar :)
They still haven't fixed them, even 2017' vag cars with DSG are already problematic. Vag wants money, not to produce reliable cars.
i have a 2013 a3 and had to have a clutch replacement at 28k km's.. currently experiencing very jerky changes between 1st and 3rd when slowing or taking off in traffic. praying its not the start of another new problem
Not automotive, Aktiengesellschaft = joint stock company
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 ?
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.
afaik it depends on the brake pressure you apply.
If you press the pedal firmly the DCT should go into neutral.
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).
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.
Thanks for that, very explanatory video. Perfect for helping with my college assignment
This is some serious sorcery! Who comes up with such beautiful madness???
CDon02 Germans. Always Germans.
can you explain the Koenigsegg direct drive transmission?
+ranavarro92 czcams.com/video/naRY3knqFYU/video.html
If Charles was my mechanic, I would break my car on purpose every week just to see him. Nice beard!!!!!
yeah I dont think he'd respect all that much lol
+Tecnologia Brasil You don't have to break it on purpose, it'll do it itself, don't worry
I don't believe this. Maybe the old DSG gearboxes but definitely not the ones on the new cars. Mine is flawless.
Tecnologia Brasil My mate, bought a brand new Golf Polo GTI a few years back, has about 40,000km on it, about to go through his second DSG gearbox.
+Nevsack63 Then your mate is an idiot or really unlucky. This is my second Golf with a DSG and not a single issue. Both had the 6 speed DQ250 and not a single issue whatsoever. My first car with the DSG was sold at 89,000 miles. Not a single problem with the car either, in fact it was part exchanged and the dealership didn't bat an eyelid because they had all the servicing history on their system and knew the car. The guy that did my MOT for the past 3 years after the first 3 that the car was new, he asked me why I didn't tell him that I was selling because he knew that the car was perfect and he was interested in buying it. My previous car never failed an MOT, not even advisories. All servicing done at VW dealerships at the correct time and I followed the schedule correctly. If people treat the car like shit, take it to back of the house mechanics, use non-genuine replacement parts, out of spec oils, etc then the car will break. These are not the shitty 80s car anymore, these are machines built to tight tolerances so people who treat it with an 80s mindset will break them.
That was great... I already had a solid idea of how this works, but seeing it and getting an exact explanation made it much more clearer... thx very much.
good job very clear , I understand how a gear can be pre selected now, I didn't understand how that was possible before
Question: I thought you said that the main purpose of a dual clutch transmission is to separate odd and even gears for speed, but in this video you state that the output shaft #1 had the gears 1, 2, 3, and 4. 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? :)
That's actually 2 shafts, one above the other, just like in the whiteboard video. 1 & 3 on the top shaft, 2 & 4 on the bottom.
They didn't explain how 5 & 6 work on an extra shaft, I can only assume at least one of the first four gears acts as an idler???
Anyway, all those (big) cogs look like loads of rotating mass, you'd barely need to engage a clutch to keep feeding torque to the wheels!
as I understand it, the shafts that separete the odd and even gears are the input shafts (the concentric ones), not the output.
Damn, when you see the parts and complexity, it gives me an appreciation of the cost to work on these. I wont feel so bad when my wifes clutch blows out!!!
Great video. I had wondered how this system worked and you have explained it for me. Thank you :)
1st transmission video that I actually understood. It's finally setting in. Now just a bit more studying the differentials.
what are your opinions on dual clutch transmissions? are they good/reliable?
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.
Keep in mind that im talking about transverse versions. I dont know about longitudinal found in audis
they suck
This is hurting my brain 🤣
Great video with those gears, selectors and shafts on show.
wow I never seen a dsg taken apart before...its seems simple yet complicated...I had to watch a few time to understand everything...thanks for the video
