  1. 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.

  2. My question is : does a DCT needs a torque converter or it is engaged directly to the engine through multi plate wet type clutch?

  3. 2019 and we're still using metal on metal gear driven mechanisms. Should be using tube technology! Most engines are still held together by a big rubber band.

  4. In 10 minutes I learned how car companies fixed something that was not broken. My Honda conventional automatic has 255K miles and still has no problems… another stick I had had 380K miles and needed one clutch. Cost to replace: $198 dollars. You can keep this junk… nothing personal.

  5. I have a VW Up! (Not sure if sold in the USA) which has a ASG gearbox, it’s been described to me as a automated manual gearbox…is it similar to the DSG?

  6. 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!!!

  7. The mechatronic of my DSG gearbox actually broke down.. i got it fixed by the dealership. But how is it possible that this specific unit can become broken? What could be the cause?

  8. If they want to make a transmission that behaves like a manual transmission, why not just put a manual transmission in the thing?

  9. This was very interesting. But how does it shift so smoothly? In a manual, if you drop the clutch, you get jolted back, but here it doesn't happen. Does it double clutch automatically or simply, since the gear change happen so quickly, the RPMs don't drop?

  10. New 2011 1.6 Tdi Skoda Octavia with DSG 1) Clutch breaks within the 1st year (replaced the whole clutch) 2) Clutch breaks again on the 4th year (they changed only the even gears) 3) Varta battery blows up, ECU of gearbox burns up they replaced the ECU and changed the oil into a brand new one recommended by the company….6 years on and I have a judder when I move from 3rd gear to 2nd gear but the gearbox holds up for the moment. Compare this gearbox with my 25-year-old supercharged 4 speed auto honda and you can tell this gearbox is s**t.

  11. Sometimes I can feel my car (2012 VW CC) trying to pull forward when I'm stopped, even with my foot on the brake. I assume that means the DSG is riding the clutch slightly, which is something you don't normally want to do. Other times, I can tell that the car has done its best to release the clutch entirely while I'm stopped, and when I take my foot off the brake on those occasions, I can feel a slight delay before the clutch engages.

    For that reason, I like to shift to neutral at stops, since I can't disengage the clutch "manually" any other way. Is that a big no-no? I'm wondering about mechanical issues, not "best practice" driving technique. In fact, my sense is that the car shifts into first and takes off faster when I hit Drive and go. The car sometimes takes much longer to engage if it's in already in Drive but has decided to disengage.

    Probably will keep doing it unless I hear a well-reasoned argument against. I like feeling "in control."

    Has anyone seen a VW white paper on how to drive the DSG to best advantage?

  12. would you say the jerkiness also appears on the DSG if you begin to accelerate and the quickly decide to stop hard?

  13. 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.

  14. I hear you but dont understand….this box is very clever.
    I wonder how long it took the vw engineers to crack their first DSG gearbox…….
    Witchcraft.

  15. Gerçekten çok güzel videolar çekiyorsunuz Hepinize çok teşekkür ederim Türkiye'den selam Oto Servis olarak sizlere takdir ediyorum

  16. Finally, after a couple of years since having seen this video my mechanisms professor has told me to see this video in order to understand dsg's.

  17. Nice job tag-teaming and explaining the DSG. As one with auto and manual trans experience in a previous life, everthing made perfect sense! 😀 I WAS disappointed not to see a duet from you two as an encore! 😉

  18. I love mine. Works like a charm. 45K miles so far. I've heard bad things about the ones from other manufacturers, but VWAG seems to have it right.

    Do NOT skimp on maintenance. Change the fluid at the recommended intervals. And drive it like a stick. Don't just pound the pedal like you have a slushbox.

  19. This did not explain the main weakness of dual clutch gearboxes, stop and go traffic causing overheating and premature failures.

  20. Which automatic gear box used in benz,bmw,jagur,ferrari etc..
    is it planetary type gear box ?
    Now is any planetary gear box used in any vehicle

  21. I have a 2.0tsi scirocco and id like to know if it pre engages gears BELOW the gear your in. For example, I am coming up to a hill and downshift manually from third to second, will second gear already have power applied to it or is the pre engagement only on upshifts?

  22. Can I just say a massive thank you for helping me out with my college transmissions essay. Really couldn't understand it before!

  23. i've seen flywheels of many jetta's and passat's rattling and at 15000 miles an then cost a bomb to replace. any idea why so many premature failures?

  24. DSGを採用する車はこのようにドライブトレインが非常に重くなる。だから高価な馬力(トルク)のある車にしかつかないんですな。
    F1のを見たけどフォークシャフトに工夫がされている。これを一般車に簡易的なものとしてできんものだろうか。Thank you.

  25. VW needs to know we need very very very very reliable cars and not cars that shift faster, car technology has come so far and drivers have no idea about what is underneath the hood, and couldn't care less, we are curious yes, but when it comes to buy a car reliability is very important, what is the point of having a car that shifts faster when you can not even drive that car cause breaks down all the time and plus is very expensive to fix and plus is hard to find mechanics to fix it, why this companies sell this disposable cars to us??? I guess profits… oh well , answer was not that hard

  26. OMG. So complex and efficiency lost because of all the gears friction. Pure electric motors definitely win in this department I’d reckon. Thanks for explaining though

  27. In theory could a DSG be given a fly by wire clutch as it were that could be used to manually operate the clutch if desired? Does the mechatronics unit (as VW call it) have the ability to provide that level of control if it were to be manually operated?

  28. motorcycles and indy cars been using this setup for many years. one example is the VFR uses a similar set up, and its pretty cool.

  29. Can see why you have so maby subs another great video its a little bit like a bike clutch with the basket and the individual steel and friction plates in oil

  30. Hello sir
    I wanna ask , if my clutch pack cover leak
    It can cause my car wont shift up from 1 to 2
    My car 2010 gti mk6
    Please reply thanks

  31. I’ve been trying to wrap my brain around auto transmissions for 25 years. Still doesn’t make sense. But I like shiny!
