I must say that this is the best explanation of a complex PDK I have ever seen, your patience and delivery are superb ✅ you have my Respect gratefully sir
|10/10. This strikes a really good balance between complex mechanical engineering details and the practical stuff that a reasonably mechanically-minded driver wants to know about PDK. Delivered with great clarity and demonstrated with an actual PDK gearbox stripped down. Well done, thank you.
The reliability of the PDK when considering the complexity is amazing. 83k on my 981 with no problems. I change half the PDK fluid every year as a preventive measure. The transmission is simply sublime for its speed, and its flexibility. Porsche is an amazing engineering company that makes the best cars in the world, with all parameters considered imho.
@@UhOhUmmI hear people complaining about the DSG, but I had three cars with DSG, two with DQ200 and one with DQ250. I drive mostly in town where the traffic is very busy and never had a problem. The DSG are made by Borg Warner as far as I know, but I thing that the concept is similar
@@fprintfperformance sports cars usually go about 120k before issues. A luxury performance car like a Porsche is probably being driven harder and in most cases less meaning older parts with less miles on them tend to fail due to age rather than use.
Kudos to the engineers and the precise manufacturing behind this unit. ZF certainly deserves their place near the top of the food chain for transmissions. Extra kudos to Jeff for explaining such a complex system in a detailed and intuitive way.
The primary reason I work on my own stuff is because I love to learn how things work. Digging into the mechanical "how and why" is almost as fun as driving the car. Thank you for sharing your knowledge.
Seems a beautifully built mechanism. I know all modern engines and gearboxes are really well made with precision CNC components. But I reckon Porsche engineering is another step up. As a Porsche owner, I like to imagine that is the case.
When I see how complex and advanced engineering it is, you understand why a new one is expensive. It's not exactly simple few parts, Thanks for explaining 🙂👍
Wow what a video ,its amazing the Pdk works so well . Bought my first Porsche 2014 boxster s guards red 14 k miles .drove it 500 miles last week. Love it.
I bought a 2005 Audi TT with the Original DSG- the second year they were available. 18 years as a daily driver and the transmission and engine have been bulletproof. The key is that the DSG will NOT allow the driver to run over redline, even in manual mode. And it won’t let you lug the engine. It never misses a shift, never forgets to shift into 1st at a stop, always gives a perfect throttle blip to match speeds, and gives as close to continuous power as any clutch geared transmission could. It protects the engine and the transmission from over-exuberant drivers. The transmission was so amazing that Porsche demanded a 7 speed version for their division. And Bugatti got one, too, for the Veyron. Mine still drives like new. Married to the TT’s Quattro driveline, it’s a fantastic driving machine.
Had my 2018 Audi A5 Sportback for 6 years now and in love with the DCT, same no issues at all. I will keep and drive this car till the wheels fall off. BTW, congrats on your car lasting this long.
@@_Mario_PL_ I just invested a bunch of money in mine. 18 years of being parked in the sun had started to burn the clear coat so I had the spoiler and top of the car and hood repainted. The headliner had started to detach, so I had it redone. And some other issues that cropped up in the last year or two. I replaced a fuel pump, and the AC compressor. But the worst was I left it undriven for a a few months and rats got into it. So I had to partially rewire the ignition harness, and replace the headlights- the rats had gotten inside the headlights and chewed them all up. I also replaced the instrument cluster because the red screen had lost a lot of lines. ( I am considering having the available color screen installed. - but might want to keep it stock ) But I still haven’t had to do a thing to the drivetrain. So the way I figure, I am not gonna LET the wheels fall off. In six or seven more years It might be my grandson’s first car.

Thank you so much, I had to engineer a DCT in university, and it was like the PDK, but I never had the opportunity to see it in a real application. The video provides a good example that accurately reflects reality. I wish I had that video 2 years ago, I think it would be a good help. Thank you!
Fantastic video. Everything is explained with a great use of graphics and then the real items for consolidation. Can’t wait for part 2. This makes me a little less scared of the PDK in my Cayman. Such a minor thing, but seeing how “park” works was such a little joy for me, I’d never really thought about it previously, such a simple solution.
I was always being very ginger when putting the car in park and slowly letting off the brake to protect my gears, but now I see they use a large heavy-duty gear for the task.
Excellent breakdown of the intricacies of the PDK transmission. You went the extra mile to explain all the inner workings of this well engineered transmission. I applaud your efforts, great job.
Amazing. It came to mind for me that the inner components and interactions of a single biological cell are possibly magnitudes more complex than this marvelous mechanical human invention. Thank you for sharing.
Yeah. I'm studying to go into the medical field. I have studied mechanical stuff like this since I was young. I'm a big gear head and these contraptions just make perfect sense. Biological mechanisms and chemistry are still often times utterly baffling to me. I'll get there one day.
@@RobotDCLXVI I once read something worth pondering. For years the Government had a science program underway called SETI (Search for Extra Terrestrial Intelligence). The radio telescopes were constantly scanning the universe attempting to pick up any signal that was not just random noise. The computers had algorithms that would detect normal random radio waves from those that were sourced from an intelligent distant life form, which so far, they have never detected. But the interesting thing is that when those same sophisticated computer algorithms were pointed towards the DNA molecule the answer that the computer generated was that the data of DNA was sourced from an intelligent being. I think that is fascinating.
Awesome vid! I had a summer job whilst in college, it was at a GM plant in Cleveland OH, mostly the plant was big presses and metal stamping, but they had a fully automated line making automatic transmission gears, that line was amazing to watch step by step. Raw metal in, finished gears out, and it appeared to operate flawlessly.
11:42 the Hunting tooth ratio concept is so fascinating. In computer science we have a very similar concept when it comes to the modulus used for a hash table. We always use a prime number to prevent uneven distribution of items into slots.
We use a prime number to generate our numbers space because otherwise, the numbers modulo would not form a field; it would only create a ring, meaning the multiplicative inverse would not be unique/ be defined. I am unsure what you mean by "uneven distribution of items into slots," but perhaps I misunderstood. :)
Excellent video. I knew the basics, but these vids are packed full of detail I'd never thought about, like how 1st and reverse are on the same shaft so they both use the bigger clutch, and how the control hydraulics work. I knew the concept of hunting tooth gears, but never knew it had a name. Thanks

Fantastic explanation. It’s a masterpiece, nothing new really, just automatic transmission technology meets, manual, only addition is dual input shaft. Fantastic, definitely like one in my classic
In the first stages of viewing this video so far, it seems like an excellent presentation. Thumbs up from a 7-speed manual owner in my 991.1 GTS. Looking at those valves and how new components shed material, I would tend to change my PDK fluid far more often than the recommended interval, but that is just me. The wet clutch is exactly how motorcycle clutches work, but they are manually activated. By the way, the 7-speed manual transmissions has just as few parts available.
Many years ago an old friend and I were involved in getting a Constadt Daimler running ( a vehicle built in around 1897). This car belongs to the British National Motor Museum, in Beaulieu, UK. We could not understand why the final drive (a huge cast iron gear bolted to the rear wooden wheel had 99 gear teeth, now I know) thanks for explaining that. Tony Hillyard, France

@@jimsteinway695 Not even the Porsche dealers will fix a PDK, so if they don't want to fix their own car, neither will I. This is why I only own Porsche's under the manufacturer warranty.
Porsche and ZF have made something special. Even more amazing that this 1980s spec. fitted to the 956 and 962 race cars has become ubiquitous in everyday Porsche cars - and other marques. Long history before today though, starting in 1939
Let me preface this by saying that your presentation and explanations, especially the visuals, are excellent and truly appreciated. That said, I can't share your enthusiasm for a company that goes out out of their way to severely limit access to information and parts necessary to repair something as expensive and critical as the transmission. The end result is a burdensome and unnecessary cost to the average consumer of being forced to pay to replace the entire transmission when a problem arises rather than just replacing the individual parts involved. Most shops, including Porsche dealerships themselves, won't even take the time to look into the transmission to make a complete diagnosis bc they know that even if they do find the problem it's unlikely they'll be able to get the parts to fix it. So you end up with a situation like that just posted on the Grassroots Motorsports channel where an owner sold his Cayman at a substantial loss bc he was quoted $15k to replace a transmission that could have been fixed with $50 in parts. Something is very wrong when various forums and RUclips videos are the only access consumers and technicians alike have to repair information.
My Datsun 240Z had a similar failure to that Caymen you referenced. The roll pin broke/fell out of the shift shaft connecting the shift fork between 3rd and 4th gear. I added a second roll pin inside of the primary pin, per the Nissan Motorsports recommendation. I think it cost ten cents, plus a weekend of my time, to fix the trans.
Thanks for the video. As an NSX enthusiast (both gen1 and gen2) I would love for someone to buy a NC1 (Gen2) NSX and do a complete teardown like you did with your Boxster. The 9 speed DCT in the gen2 NSX is unique as the clutch activation is hydrostatic from a pair of electrically controlled hydrostatic controllers. The shift forks are electrically activated by an electric motor assembly made by Shaffer. The NSX gearbox has no valvebody. Even though it uses wet clutches, the control and activation mechanics is more like a dry DCT.
Great explanation. Fascinating. I’ve had VW’s with DCT (“DSG”) since 2007 and get on well with them. My first one had the dry clutch, but later ones the wet clutch which I prefer. I have always felt the wet clutch to be a better solution for heat dissipation but, as I understand, the wet ones are “less efficient” for fuel economy purposes. I never hold the car on the clutch - mechanical sympathy. I do understand that DCT’s are not the ideal companion for those who tow and/or need to slip the clutch eg for manoeuvring or very slow take-up. What seems slightly odd to me (as a non-engineer I might add) is that the DSG is programmed to prefer to clutch-slippage in 2nd gear rather than full engagement of 1st, eg in slow-moving traffic. This (to me) feels uncomfortable from a clutch wear/heat point of view but I do get it that constantly changing to first gear in traffic could be criticised for being more jerky which the driver would most likely dislike (low speed jerkiness is a criticism of DCT’s). My solution in very slow traffic is to use “sport” or manually select 1st when I want it - either is easy enough. We also have a car with an Aisin torque-converter 8-speed box which I am more happy with in slow/crawling traffic situations.

What seems slightly odd to me (as a non-engineer I might add) is that the DSG is programmed to prefer to clutch-slippage in 2nd gear rather than full engagement of 1st, eg in slow-moving traffic. This (to me) feels uncomfortable from a clutch wear/heat point of view but I do get it that constantly changing to first gear in traffic could be criticised for being more jerky which the driver would most likely dislike (low speed jerkiness is a criticism of DCT’s). My solution in very slow traffic is to use “sport” or manually select 1st when I want it - either is easy enough.
We also have a car with an Aisin torque-converter 8-speed box which I am more happy with in slow/crawling traffic situations.
Great explanation

Excellent video and the best info by far on the PDK transmission!!
This explanation also explains indirectly why I don’t ever use launch control
Excellent content Jeff!!! Keep it up!
It takes me the life of a vehicle to figure out its automatic controls. It takes a month for me to master a manual!
Thanks for this amazing educational video ! 🙌🏻
