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
Thanks. I appreciate the feedback.
@@jeffrichardsoncardiytop quality
😊
Fr well done!
It’s amazing how something so complicated can be so reliable. Excellent presentation.
Precision and quality of materials make the difference between a reliable and unreliable mechanism
And changing the oil and filter when recommended.
@@Xenstein Also good engineering makes a pretty big difference.
|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.
Thanks. That's what I was aiming for.
Spot on!
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.
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 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.
Why half the fluid? (Not saying I think there is an issue there) What is your filter replacement regimen? (Mucho importante)
@@user-mh2ho3mj4nbecause half a brain
DSG is just as reliable. I wonder if it's that much different.
I guess it is all perspective. I'd consider 83K on any normal car to be 1/2 the life of a normal transmission. e.g. it isn't anything special.
@@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
The structure of the PDK, which is complex even if you just imagine it, was absorbed into my brain thanks to your kind explanation. Thank you!!
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.
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.
The best clutch Is actually the Tesla plaid single clutch
@@Theworsttubesperiodttesla doesnt have clutch
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. :)
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 🙂👍
Mega explanation, pdk is the best transmission in the world
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.
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.
Wow. Thanks for this and all you have done for the P-car community.
Amazing...i didnt expect this quality and thoroughness.
Really appreciate these videos, Jeff. Thank you.
Porsche Club of America, it's time to bring Jeff to the US for Tech Tactics Live!
Anxious to watch part 2
I have an 18 gt3. I sure appreciate the mechanic explanation you’re giving. There’s a reason everyone copies it
3742 likes and not a single dislike, insane quality sir
Excellent presentation Jeff !
Wow. Blown away with how detailed this is. So interesting ! Thanks for shooting this, and helping out all us gear heads :)
This is now two of your videos I’ve recently seen that I’ve enjoyed very much… subscribed!
Mighty video , well done
Outstanding presentation Jeff. Simply outstanding.
Thanks for helping improving my understanding of these clutches by a very big amount, great video.
Well done Jeff, very informative and useful.
Thank you sir, a wonderfully shot, structured and accessible insight into some brilliant engineering!
Wow!!! Amazing tech explanation. Probably the best I ever saw. Thanks
What an incredible, detailed and fantastically logically broken down explanation of anything I've ever seen. Absolutely love this!!!! Sub'd!!!
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.
Thanks a lot for this video! Always wondered how the mighty PDK works
That is the clearest, most comprehensive description of the Dual clutch design and operation ever seen. massive thanks!
This explanation also explains indirectly why I don’t ever use launch control
I expected to not learn much because of how complicated these things are but damn I learned a ton Thanks man
Great video Jeff, thank you for taking the time and effort to do this excellent explanation of the Porsche PDK transmission. I now have a much better understanding of how this transmission works.
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.
Excellent content Jeff!!! Keep it up!
That was a masterful explanation. Thank you for sharing. Looking forward to watching the other parts.
Fantastic explanation. Think I finally understand these boxes now. Great channel
Just an amazing doctoral presentation! Now, I understand the workings of a PDK transmisssion . . . pretty much :)
Awesome channel Richo. Well done. 👍
What an amazing piece of engineering!!! Your explanation is next level, I can see this video getting millions of views over the next few years, well done
Another awesome video. Every Porsche should geek out on these videos.
Excellent video and the best info by far on the PDK transmission!!
Incredible! Love your channel, keep up the good work.
That was an amazing piece of explanation, thank you
You are AMAZING for making such informative videos to educate people like me that you don't even know. Thanks a 100000 times. I would like to buy you a beer so as to show my appreciation!!!!
you are LEGEND! thanks for all content!
Engineering Explained and the Humble Mechanic explained VW DSG years ago and I did get the overall concept, but your detail is next level. I am now a sub. Thanks from the States.
Amazing video, extremely educational
what a great and interesting video 👍👍
Excellent presentation! Thank you.
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.
Great information on the manumatic.
What a great vid - even for a (semi-) experienced tech. I've just never seen a PDK in pieces. Thank you! 😃👍
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 video. Thanks from a PDK 981 Cayman S owner.😎
This video actually puts into perspective just how much engineering went into this transmission and why porsches cost so much
Hats off for efforts to make this beautiful but very informative video for all of us car lovers🔥
This is amazing!!! Thanks for posting this highly educational video.
Although I’m already intimate with how this all works, very informative and entertaining video anyway. Well done. Keep on repairing so called sealed items.
Thank you! Bring on Part 2!
Awesome information video. Very well done.
This feeds my thirst for mechanical know how.
Thank you for sharing 👏🏽
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.

Amazing, thank you so much for the explanation!
Brilliant, this is an excellent explanation 👍
Jeff; thank you for video.
Respect!!!👍👍👍⚙️🛠 I can only imagine how many hours was spent 4this great video presentation. Thank you. Well done sir!😃
Great explanation
Great job! Keep the content coming. Inspiring me to want to take on a Porsche project car.
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.
Brilliant. Thanks for this.
You earned my subscription good sir, very informative. Thanks for the video
Best & Detail explanation of a Dual Clutch System
Fantastic video
great video 👏🏻
Great to see. I build the end of linie test bench für this transmission years ago. 😍 I learned a lot about technology and very important, the collaboration acoustics of the engine and transmission. 👍
Martin, I'd really like to get into your head if you were open to it? Talking to people who actually worked on these transmissions is extremely valuable and can open up a world of additional info that would otherwise be unavailable.
If you are happy to talk some more, can you send an email to the channel address, jjrichar12@gmail.com so I can reply and ask some questions?
Thanks Jeff
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
Amazing tutorial!
Looking forward to part 2 - your clarity & care in explanation with simple but effective diagrams is fantastic. Insta-subscribe.
Danke dir! Thank you for sharing the information!
Im a mechanic and this was by far more advanced than you give credit! Its very similar to the 02e from vw thanks for sharing.
Amazing! Thanks a lot for this!
Well conveyed, transmissions are a bit of a dark art to some but you have definitely shed some light upon the forest
This is great stuff - thanks!!
Great video, thanks
Great information, thank you
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.
incredible video
Wow man, this is some precious info right here you're giving us, thank you so much.
Now I can stop assuming and be 100% sure that 90+% of the mechanics are dead fucked when will receive a dct in the shop.
I have super strong doubts that they will have any patience with this.
Excellent video!
Just amazing, thanks
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.
Amazing videos!
Brilliant mate
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
