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.

@@_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.

@@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.

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.

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 KZbin 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.

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.

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.

The video is really well done. But I'll have to watch the sideways movement of the synchroniser rings a few more times to really understand which movement they make and when. What surprises me, however, is the position of the sealing rings at 28:25. To me, the sealing rings look mounted the wrong way round. Normally, these seals are mounted so that the open side of the sealing lip is pressed against the wall by the oil and thus seals better. But perhaps the people at ZF have deliberately fitted them this way for reasons unknown to me.

@jeffrichardsoncardiy 9 ай бұрын

My understanding is that the fluid pushes past the first seal and is stopped by the second. A little counter intuitive, but maybe it's so the gap between the two is full of fluid for lubrication.
