I researched these transmissions when I was looking to buy a 2015 Focus. I wasn't willing to gamble on one so I got a 5 speed manual instead. Much better transmission in my opinion.
These transmissions are absolute shit. We bought our 2015 focus new and had nothing but problems with shuddering. It's been back to two different ford dealers and they say it has "acceptable" shuddering which is a cop out. They should have been recalled. Stay well clear of them
@@peteryates9153they were recalled because customers won the law suite. However, because the manufacturers of these transmissions coincidentally went bankdrupt, the best ford could do was give you a certificate for a discount on their new cars if you were to purchase from them.
The observations about the assembly grease on the release bearing, missing snap rings, and preload consideration on the differential bearing was interesting. I mean the operation that I understood (mostly) was also appreciated. Thanks for making this very valuable video!
I have a 2013 Automatic Focus. I am experiencing clutch judder on pulling away. This video was invaluable in understanding the problem and more importantly the correct remedy. Thanks Mark H UK
Thank you! Very happy to see so much detail. I have one of these cursed things in my 2013 Focus. It shifts exactly like I did when I got my first manual car (terribly), but unlike me, it never gets any better at it. Love the technology; hate the implementation. There have been several TSBs and revisions to the input shaft seals to keep oil from escaping, running down the shafts, and dripping on the clutch discs. There have also been at least five clutch plate revisions. Ford no longer makes their TSBs public, so I don't know what's happened over the past year. Mine had bad seals and had a clutch replaced under warranty. It no longer has the aggressive shudder it had when the clutches were contaminated, but it still shifts horribly. The TCM "learns" as you drive it, but seems to actually get worse at feathering the clutches. It's worst when accelerating from a stop or shifting from 1->2. Possibly amplified by the shortness of the first two gears. Lastly, something inside the box makes a horrible grinding sound, especially when under acceleration and turning left. Ford repeatedly told me this awful, embarrassing noise is "normal". It sounds just like I'm dragging a six-foot steel rod behind the car. I haven't heard a clear explanation as to what's causing it, but I wouldn't be surprised if the box was slowly eating itself. Glad I'll be free of this thing (and Ford's incompetence) after only one more summer.
James Wagner Thanks for the feedback. Hopefully the newest version of the clutch and/or TCM software will improve the driving experience. I would check with your Ford dealer to see what updates are available. Thanks for watching.
@@WeberAuto yeah and the customer will have to pay for that instead of having it done for free like it should be since the customer isn't responsible for this poor design.
Yep feels just like a teenager just learning to drive a manual. Mine is especially bad first to second....really "feathers" the clutch between gears. Inspires a lot of confidence when pulling into traffic.
36:15 They are called Shift Drums. The design has been used on Motorcycle gearboxes for many decades, although most are single clutch, using a single drum with Three grooves.
Those selector gears (electric motor driven ones) are pretty much the same as in sequential racing transmissions, which you usually move manually, so there's nothing that much new, but a new combination of old things. Nice to see it apart, thank you for your work!
Thank you for your detailed explanation. I'm in Australia and 2015/16 models are in the spotlight at the moment. I really appreciate your work and your special effort in all your videos. Thanks again.
I'm really impressed by the way you explain the what is what. My step dad was a shade tree mechanic. So I kinda understand the process of the repair. My dad was a great mechanic!
Okay guys, listen up here. Shuddering is caused by non-aggressive driving. Which means the more you take it easy on your accelerations from a stop, the more the clutch slips and causes overheating problems with the clutch disc and flywheel. This causes "hot spots" on the pressure plate and flywheel creating "shuddering". There is nothing wrong with the shuddering condition, your car won't break down. P073 codes and lack of reverse or forward movement is caused by a faulty TCM. Ford also has hidden warranty on this, so inquire before you pay for repairs. A replacement TCM is usually necessary followed by reprogramming and clutch "re-learn" procedures. If you have to pay, you should know that the TCM takes less than 1hr to change out, but I don't the cost of the TCM itself. The Focus is a fantastic car otherwise, great on fuel, handles like a dream, comfortable and fun to drive! That's all I can say about that!
Thanks for the wonderful explanation on the inner workings of the DPS6 Transmission. Really nice design, but be execution love the low miles of the car, I can deal with the shudders, but mine just went out, and luckily I'm covered by some coverage extension. Hopefully the next ford I get won't give me this much trouble, and again thank you so much.
Thanks for a fascinating description of how it works. I tested a Focus with Power Shift to-day (25th April 16) and I was very impressed by it. From comments below I am somewhat worried by its long term reliability so I still have to make a final decision
Excellent and thorough review! I researched the Focus when looking for a car in 2012 and this transmission had me look at the Chevy Cruze. The Focus is a nice car, but the transmission seems very costly to fix and maintain. Thank you
I have one of these, and never changed the clutches but had the TCM replaced once. 213k miles. It does buck a little when getting the shafts to the same speed from a stop, but I've changed how i drive to better suit it and it drives pretty well. I give it what i know it expects with throttle position to better its shifting and it does just fine for me. A seal on the CV let it leak and now it makes some noise from being low on fluid, but its topped off again and running strong- that was 40k miles ago. Lots of interstate driving is about all it sees. Probably wouldn't of made it past 60k in the city.
One advantage of a DCT is that it can pre-select the next gear. Say you're in first, the transmission will have second pre-selected, and all the transmission has to do is engage the clutch that drives second to shift from first to second, and with most DCT systems you can shift without lifting off the gas. If you don't let off the gas in a regular manual transmission, you can reduce the life span of your clutch and transmission.
The DCT actually lifts off the gas for you. And rev matches on down shifts too. The TCM "talks" to the PCM and operates the throttle. When it's working well it's excellent. Unfortunately some, like the wet clutch 6DCT450 are far too sensitive to dirty oil, and dry clutch versions can overheat their clutches.
Hello Sir.I' m from Bangladesh and l' m a headteacher, Jahangir. Your classes attract me a lot,l' m growing resourceful observing your classes, Thank you sir.
Great video. Excellent camera work. Super detail and explanation of a complicated engineering design. Too bad this Ford Product has so many problems. I am now trying to fix a 2018 Ford Focus with Trans/Clutch issues. Thanks to a bunch of CZcams videos and this one I have learned a lot about trans/clutch issues for this vehicle.
Thanks for posting. I had one in a 2013 focus, unfortunately it was complete crap car wouldn't move under its own power at 100 miles. I've got a dual clutch in a VW now, works a treat.
My mother's Focus uses this transaxle. Feels like a manual the way the clutches apply. Spins the tires on accident, often. And you can't brake torque it. It defaults to neutral so it revs like you have the clutch pedal depressed in a manual. Even in drive, as long as your stopped with the brake depressed. It's been in under warranty once to have a clutch motor replaced and a reflash. Certainly better than the CVT alternative, and gets remarkably good mileage, thanks to the lack of slippage.
Thank you very much for the effort to demonstrate how that transaxle works before to watch the video, I was lost :) I have not idea how it works. now I know cause I have a 2014 Fiat 500L with a Dual Dry clutch that I need to work on it.
Great video Weber. Great understanding how that double clutch works in my car now. Got my car out today and it was exactly as you explained, clutch foul from lubricant. The new seals are brown now instead of black. Ford really did me right on this one. All the recalls, and additions from the dealer I can't explain and a detail. I knew I was buying some new, really un-tested crap but I bought it anyway. I haven't had allot of problems with the car to be honest, I just figured it to be quarks but after all the work and the trans controller, it really drives nice now. Keep in mind I took the car in for door latch recall.
My friend has a 2014 as opposed to my 2013 and just complains all the time but never takes it in. Also has a Master cylinder check valve leak which screws everything up. Maybe 2014 wasn't a good year.
Thank you for your great video. I just bought a 2017 Tucson and Just knowing how it works makes me feel competent to operate the vehicle in the proper way so as not to prematurely wear the dual clutch.
Transmission rebuilder for 40 yrs here, this concept is off the wall crazy, many other ways to achieve automatic operation within transmission. A 5 speed standard manual clutch operational transmission would do wonders for this Ford Focus vehicle. Today’s breeds of humans couldn’t grasp standard clutch operation. Cell phone texting is what they excel in.
As noted one major difference between this transmission and a traditional manual is that the two apply bearings push to engage the clutches, which is the opposite of a throwout bearing that pushed to disengage the clutch when the pedal is pushed down in a manual transmission vehicle. In a manual throwout bearings used to wear out and need periodic replacement along with the clutch. It was an ongoing and repetitive maintenance liability. And if the driver had the bad habit of resting his foot on the clutch pedal the throwout bearing would spin continuously and wear out very quickly. My fear is that along with the dual clutches needing periodic replacement the apply bearings, which are spinning continuously under load during cruising, will also require periodic replacement. There are already reports of these transmissions needing clutch and/or apply bearing replacement at 25,000 mile intervals. This will be very expensive for the owner if the vehicle is out of warranty.
True. Also in a wet clutch arrangement the transmission could continuously feed lubricating oil to the release/engagement bearings (or whatever they call them) to extend their life. The problem with a dry clutch arrangement is that the bearings only have the lubricating grease packed inside them that has to last the life of the bearing, which has to spin continuously under load for long periods. I've read reports of loud grinding noises during gear changes coming from these transmissions. That sounds like the release/engagement bearings, similar to a bad throw-out bearing in a traditional manual.
Hey John my daughter bought a 2012 Focus with this transmission had to have the two common repairs done input seals and tcm module. The problem with this transmission is the application its for supercars ripping the track all or nothing. Not for your daily commuters stop and go or the worse for the clutch creep. Let your foot off the brake you creep the clutch is slipping give it a throttle input now fully engaged. When you brake it disengages the clutch so dont creep told my daughter that and at 250,000 k this thing still going. Still think a pos put in the wrong application but still interesting the engineering it took to make this.
Great video! I have learned that ford has updated their software for the tcm so that it delivers better shifting capabilities as well as better responsiveness. I just purchased a 2017 focus in February and it rides and shifts great(so far lol). It was a big change since I traded an 05 focus for this new one. I plan on taking it on a road trip in a few years from now. Again great video! This is the only way I can learn from these hands on easy to understand videos
I understand how this 6 speed trans works, the problem is the computer module that controls the clutch and what gear it should be in is not advanced enough to shift the trans correctly or has a lack of sensors to know when to shift up or down. Also since the shift mechanism that engages and disengages the two dry clutches are driven by electric motors or survos they do not have a sufficient battery power to operate correctly because of faulty ground connections. This will cause shuddering, pausing or even the trans engaging at idle and moving the car setting at a stop light forcing the car into traffic or at other times will not supply enough drive power to merge with high speed highway traffic. Also the trans has a problem with a leak of lubricant getting into the dry clutch housing causing the clutch to not have enough friction to drive the vehicle and then the tcm or transmission control module thinks it in the wrong gear and it does not know what to do causing malfunction resulting in hazardous or life threatening operation.
I sincerely doubt that better ground connection or better servos would solve this. The fork mechanism itself has too much give. With a "normal" clutch, the springs hold the plates engaged, and the forks pull them apart. The forks don't have to be responsible for the large solid force needed to smoothly engage the clutch - that's all the spring's job. With this transmission, the springs hold the plates apart, and the fork has to supply the power to not only push the plates together but also overcome the spring tension. The forks are relatively thin and use a lever action, so they are prone to deflection. It would only take a few thousandths of an inch (hundredths of a millimeter) deflection to start oscillation in the clutch, which I believe is what's happening. Anyone who's ever used a metal lathe and heard the cutter scream while it chatters knows exactly what this looks like, and how even the stiffest machine can oscillate under the right conditions. That fork actuator is nowhere near stiff enough.
this is exactly what happened to me! . Also the trans has a problem with a leak of lubricant getting into the dry clutch housing causing the clutch to not have enough friction to drive the vehicle and then the tcm or transmission control module thinks it in the wrong gear and it does not know what to do causing malfunction resulting in hazardous or life threatening operation. what causes this leak?
Wonderful wonderful. I was secretly hoping you'd get your hands on one of the DSG (DCT) transmissions from either VW or Ford. Nice clear explanation - I've learned much. Thank you!
12:00, my car unfortunately has one of these (2014 focus) and in practice it is does not act like a traditional automatic transmission lol Thanks for making this video though, I love to see how the internals of something I own work, especially explained by someone that knows what they're talking about.
No matter how interesting the pieces and How majestic the configuration, it failed on Ford vehicles, that what matters! my 2017 Ford Focus shakes like a belly dancer when it shifts the lower gears!
Awesome video as always. I greatly appreciate the time you took to present this. I find it fascinating to witness something broken down into digestible chunks. It's also amazing to discover the workings are actually pretty straightforward! I have absolutely no idea how somebody would give this a thumbs down!!! Ignoramus!
Thank you for the detailed video! The Powershift automatic is garbage and just about everyone knows it. The Detroit Free Press did a large article detailing all the problems with this transmission. If you have one and haven't had it fail yet consider yourself lucky. I had mine under a year and they had to replace the transmission because it would not drive, just slipped constantly. In the five years I have had the car it has been in the shop a dozen times for transmission issues. Just this past week they replaced the clutch again and now the differential bearings are worn out. Up until now the warranty covered all the repairs. Now they want $2k to fix it! Should the differential bearing last longer than four years? They put a brand new transmission in just four years again almost to the day.
On my third transclutch in my 2012 Focus. Ford says this is an improved part. After 5 years of a shitty driving experience the jury is still out on this latest fix. After all the years of shuttering one of my engine mounts gave out and the car was vibrating terribly. Now that is fixed and for the first time after 50,000 miles it drives like a normal car. Hope it lasts. This is my last Ford. Give me a normal transmission with a torque converter, this is for the birds.
In my opinion, it would be very interesting to see a video describing the single dry clutch Magneti Marelli "Selespeed" automated manual transmission, used for example on the Ram ProMaster (Fiat Ducato) 3.0 EcoDiesel.
KEY for this trans: your battery has to be in good shape; less-than produces inferior shift motor operation ('shuddering' complained-of etc.). So half-life to new is necessary (alternator doesn't supply necessary amps at low rpms, where 'shudder' happens) with this trans. NOT A CLUTCH issue but instead Mexican servo motor requirements, or they'll turn later and slower, and you then 'hear about it' :)
That is amazing, I was wondering what that lurch was between 1st and 2nd, turns out it was the engagement of one of the two clutches as the transmission switched input shafts.
John, lots of problems with this DCT in Focus and Fiesta, still on 8 week backorder cycles for the newest seals and friction material. Warranty was extended to 100,000 or 150,000 miles (don't remember which). Lots of complaints on the forums, and lots of messing around to even get in line to have this fixed.
We got the same warranty extension150000 Miles when the clutches went out for the 3rd time at 89000 miles we took it in and the dealership said that was only for computer reprogramming. The cost was $2200. Thanks ford, and they wonder why people buy foreign.
I've been driving a 2012 Focus with the DCT for 80,000kms now, the Trans control module failed recently, causing it to pop out of gear, we're getting a new TCM now, but as I've done trans work on other cars I was curious to see how it works, just 4 electric motors really do the automation, I find the car is quite conservative with its clutch slippage, probably to prolong the life of the unit, it still has pretty fast upshifts and puts the power down nicely, good stuff!
It's shocking that Ford uses such low-quality seals in this transmission. Today I picked up my car from the dealership after the third clutch pack in my Focus was installed (factory and two replacements) due to seal failure. It's so nice not having to rev the engine to 3000 rpm to eliminate 1-2 shift shudder anymore. This is the second time I have heard that Ford has used replacement seals of better quality - although I was told the last time the clutch pack was replaced (July 2015) that it should have been fixed permanently.
I've had to replace both clutch assemblies (during a single failure event), The question came up... "What about using the cruise control to down-shift coming down a hill?" This was actually a great question and needed some testing, I had cruise control set to 45mph over an arched bridge which had a speed limit of 35mph at the exit. coming down the arch of the bridge, i used the cruise control for the rise of the bridge arch and then used the "Coast" button to slow down... it will shift into lower gears to use engine compression-braking. This should be included in the performance notes.
Thanks for sharing! I believe this is the same transmission as in my 2014 turbo diesel ford mondeo. I spend a lot of time driving it in manual mode as the engine is so ridiculously noisy I prefer to upshift early rather than listen to it. It also takes some getting used to, in that it does not creep forward like a traditional auto when in drive and on heavy acceleration combined with the turbo lag there is a full second of nothingness on every takeoff followed by uncontrolled wheel spin.
Hi, the Mondeo does use a Getrag DCT, but it is a different model that is little stronger to handle the diesel's torque. The model number is 6DCT450/6DCT451. Thank you for the feedback about the operation of the engine/transaxle combination in your car, that second of nothingness would be annoying. Thank you for watching.
VW don't use wet clutches on all their dual clutch transmissions, when they went from a 6 speed wet clutch in the mark V golf to a dry clutch setup in the mark VI. These have more issues and can burn out and shudder quite easily and were subject to many recalls and fixes.
Thank you, your videos are always very informative. Its always interesting to see how DCTs and ECVTs are competing with regards to fuel economy. Hondas fit (with i-DCD) is quite interesting architecture as it also has a planetary gear.
This transmission has been a huge problem for Ford. If you could get hold of the comparable VW Getrag that doesn't seem the same problems it would be interesting to see the differences if any.
Look at the TSB's on these transmission before buying a car with one, just a warning. Not sure if the 2015's are any better but previous models years had lots of problems. Apparently the problem starts from the seal on the input shaft leaking fluid which gets in the plates, which you sort of seen in your video, whether than was grease or fluid can only guess.
I wonder how did you cleaned it out the in-house, it looks nice 👌 I took down mine but I couldn't clean it like that...😢😢😢 Thanks for the video very goo general information 👍 👍👍
John, I’d like to offer some professional advice about your microphone use. The mic capsule is picking up far too much low frequency that does not help understanding. It also seems to have too much gain and is overloading its preamp or your interface. These two problems are interdependent to some degree. Let’s start with placement. Move the microphone so that it is not in front of your mouth but rather to the side of where your lips meet. Keep moving it in that direction until you hear the clearest pickup in your headset. You should hear no puffing of wind from fricative consonants no matter how loudly you make those sounds. Second, try lowering the gain of the microphone signal about 3-6 db. You should hear some pretty obvious improvement once it is hitting the preamp or compressor after the preamp less hard. Depending on the path your mic signal takes there may be low cut adjustments as well which will make a big improvement. You do fantastic work and I’d like the largest number of people to enjoy it. All the best, Peter.
love your video on how this transmissions work, i really appreciate it, and im gonna ask you if you ever come accross a vw dgs, and do something similar, i will be great, and thank you again for your good work,
I have a VW with the 7-speed dry clutch DSG which mostly works without any drama. The big difference as most are aware is that the Getrag actuators are electric instead of hydraulic as on the VW. I have to wonder that if the next gear is not the one preselected whether the motors are fast enough to change gear without noticeable delay? And as others are, I'm amazed that they (both) use what appear to be relatively conventional technology for the throwout bearings. And that the actuation mechanism is exposed to dust from the clutch disks which cannot be good for grease present. Oh, one other item worth mentioning in your fascinating videos, inherent in this design there must be mechanical means to lockout invalid combinations of actions under fault conditions such as being in two odd or two even gears at the same time, or having both clutches engaged. Perhaps that's partly taken care of by the shift cam drums?
Absolutely amazing. I think it's a bit wrong to have special tools to work on this as they must be very expensive for garages to of buy them which would surely bump up the price of servicing and any repairs.
@@WeberAuto Sorry, I din't notice the date of this video. BTW: Great videos, I just found them this week, and already seen a number of them. Thank you.
i have 2014 focus that was slipping when i started off, now its at the ford deal getting clutch assembly replaced, i just hope it fixes the problem, ford has had major issues with them
Nothing can be done better than this. Thanks a lot for your time and efforts to explain this gearbox is such a detailed manner.

This is super relaxing video on Saturday morning and even better food for thought.
+Adam Kudła Thank you for watching!
Thank you very much for the effort to demonstrate how that transaxle works before to watch the video, I was lost :) I have not idea how it works. now I know cause I have a 2014 Fiat 500L with a Dual Dry clutch that I need to work on it.
Thanks for watching!
this is quite useful information for a normal non engineer people who own the car, thanks lots
+Cliff Ke Thank you!
I am amazed at your in depth knowledge. I appreciate your research work and your teaching skill. I wish to be like you. Thanks for the work.
Thank you very much
Great video Weber. Great understanding how that double clutch works in my car now. Got my car out today and it was exactly as you explained, clutch foul from lubricant. The new seals are brown now instead of black. Ford really did me right on this one. All the recalls, and additions from the dealer I can't explain and a detail. I knew I was buying some new, really un-tested crap but I bought it anyway. I haven't had allot of problems with the car to be honest, I just figured it to be quarks but after all the work and the trans controller, it really drives nice now. Keep in mind I took the car in for door latch recall.
My friend has a 2014 as opposed to my 2013 and just complains all the time but never takes it in. Also has a Master cylinder check valve leak which screws everything up. Maybe 2014 wasn't a good year.
Thank you! I am glad to hear you got yours fixed and operating properly. Thanks for the feedback.
@@nasmitty5261 if your friend never takes the car in to be fixed, how does he expect it to get better?
Thank you for your great video. I just bought a 2017 Tucson and Just knowing how it works makes me feel competent to operate the vehicle in the proper way so as not to prematurely wear the dual clutch.
Thank you!
Transmission rebuilder for 40 yrs here, this concept is off the wall crazy, many other ways to achieve automatic operation within transmission. A 5 speed standard manual clutch operational transmission would do wonders for this Ford Focus vehicle. Today’s breeds of humans couldn’t grasp standard clutch operation. Cell phone texting is what they excel in.
Great to see how DCT actually works. Very cool.
+William Lopez Thanks for watching!
Excellent demonstration as well as presentation of DCT. Thanks
As noted one major difference between this transmission and a traditional manual is that the two apply bearings push to engage the clutches, which is the opposite of a throwout bearing that pushed to disengage the clutch when the pedal is pushed down in a manual transmission vehicle. In a manual throwout bearings used to wear out and need periodic replacement along with the clutch. It was an ongoing and repetitive maintenance liability. And if the driver had the bad habit of resting his foot on the clutch pedal the throwout bearing would spin continuously and wear out very quickly. My fear is that along with the dual clutches needing periodic replacement the apply bearings, which are spinning continuously under load during cruising, will also require periodic replacement. There are already reports of these transmissions needing clutch and/or apply bearing replacement at 25,000 mile intervals. This will be very expensive for the owner if the vehicle is out of warranty.
Good point! Thanks for the feedback. Wet clutch dual clutches seem to be the better method.
True. Also in a wet clutch arrangement the transmission could continuously feed lubricating oil to the release/engagement bearings (or whatever they call them) to extend their life. The problem with a dry clutch arrangement is that the bearings only have the lubricating grease packed inside them that has to last the life of the bearing, which has to spin continuously under load for long periods. I've read reports of loud grinding noises during gear changes coming from these transmissions. That sounds like the release/engagement bearings, similar to a bad throw-out bearing in a traditional manual.
Hey John my daughter bought a 2012 Focus with this transmission had to have the two common repairs done input seals and tcm module. The problem with this transmission is the application its for supercars ripping the track all or nothing. Not for your daily commuters stop and go or the worse for the clutch creep. Let your foot off the brake you creep the clutch is slipping give it a throttle input now fully engaged. When you brake it disengages the clutch so dont creep told my daughter that and at 250,000 k this thing still going. Still think a pos put in the wrong application but still interesting the engineering it took to make this.
I am sorry to hear of the troubles with that car. Best wishes
Very good demonstration Sir. Thank you!
Great video! I have learned that ford has updated their software for the tcm so that it delivers better shifting capabilities as well as better responsiveness. I just purchased a 2017 focus in February and it rides and shifts great(so far lol). It was a big change since I traded an 05 focus for this new one. I plan on taking it on a road trip in a few years from now. Again great video! This is the only way I can learn from these hands on easy to understand videos
Thank you!
Thank you John. Very nice demonstration and presentation.
Thank you!
I understand how this 6 speed trans works, the problem is the computer module that controls the clutch and what gear it should be in is not advanced enough to shift the trans correctly or has a lack of sensors to know when to shift up or down. Also since the shift mechanism that engages and disengages the two dry clutches are driven by electric motors or survos they do not have a sufficient battery power to operate correctly because of faulty ground connections. This will cause shuddering, pausing or even the trans engaging at idle and moving the car setting at a stop light forcing the car into traffic or at other times will not supply enough drive power to merge with high speed highway traffic. Also the trans has a problem with a leak of lubricant getting into the dry clutch housing causing the clutch to not have enough friction to drive the vehicle and then the tcm or transmission control module thinks it in the wrong gear and it does not know what to do causing malfunction resulting in hazardous or life threatening operation.
+Thomas edwin Thanks for your feedback!
I sincerely doubt that better ground connection or better servos would solve this. The fork mechanism itself has too much give. With a "normal" clutch, the springs hold the plates engaged, and the forks pull them apart. The forks don't have to be responsible for the large solid force needed to smoothly engage the clutch - that's all the spring's job. With this transmission, the springs hold the plates apart, and the fork has to supply the power to not only push the plates together but also overcome the spring tension. The forks are relatively thin and use a lever action, so they are prone to deflection. It would only take a few thousandths of an inch (hundredths of a millimeter) deflection to start oscillation in the clutch, which I believe is what's happening. Anyone who's ever used a metal lathe and heard the cutter scream while it chatters knows exactly what this looks like, and how even the stiffest machine can oscillate under the right conditions. That fork actuator is nowhere near stiff enough.
How about the throwout bearing? Seems like it doesn't have any balls or needle type roller in it. That may cause more friction on pressure plates.
i heard there is an extended warranty on the computer.. ~150k miles (not recall though)
this is exactly what happened to me! . Also the trans has a problem with a leak of lubricant getting into the dry clutch housing causing the clutch to not have enough friction to drive the vehicle and then the tcm or transmission control module thinks it in the wrong gear and it does not know what to do causing malfunction resulting in hazardous or life threatening operation.
what causes this leak?
Wonderful wonderful. I was secretly hoping you'd get your hands on one of the DSG (DCT) transmissions from either VW or Ford. Nice clear explanation - I've learned much. Thank you!
Thank you!
Great video thanks. Really helped me understand what's going on in my transmission.
12:00, my car unfortunately has one of these (2014 focus) and in practice it is does not act like a traditional automatic transmission lol
Thanks for making this video though, I love to see how the internals of something I own work, especially explained by someone that knows what they're talking about.
Glad it was helpful. Thanks for watching
No matter how interesting the pieces and How majestic the configuration, it failed on Ford vehicles, that what matters!
my 2017 Ford Focus shakes like a belly dancer when it shifts the lower gears!
Try the grounding method, clear the grounds by removing the paint
I have been waiting for this for so long.... THANK YOU MR.WEBER
Chris Spencer Thank you for watching!
Awesome video as always. I greatly appreciate the time you took to present this. I find it fascinating to witness something broken down into digestible chunks. It's also amazing to discover the workings are actually pretty straightforward! I have absolutely no idea how somebody would give this a thumbs down!!! Ignoramus!
Andrew Porter Thank you very much! it is fun to figure out how these new transmissions work.
Thank you John. Great explanation of assembly and operation of this transmission.
i felt high on knowledge, the best drug in the world. thank you.
+sugar glider Thank you!
This is actually a pretty accurate demonstration of how smoothly this transmission shifts gears! 😏
Thank you for the detailed video!
The Powershift automatic is garbage and just about everyone knows it. The Detroit Free Press did a large article detailing all the problems with this transmission. If you have one and haven't had it fail yet consider yourself lucky. I had mine under a year and they had to replace the transmission because it would not drive, just slipped constantly. In the five years I have had the car it has been in the shop a dozen times for transmission issues. Just this past week they replaced the clutch again and now the differential bearings are worn out. Up until now the warranty covered all the repairs. Now they want $2k to fix it!
Should the differential bearing last longer than four years? They put a brand new transmission in just four years again almost to the day.
On my third transclutch in my 2012 Focus. Ford says this is an improved part. After 5 years of a shitty driving experience the jury is still out on this latest fix. After all the years of shuttering one of my engine mounts gave out and the car was vibrating terribly. Now that is fixed and for the first time after 50,000 miles it drives like a normal car. Hope it lasts. This is my last Ford. Give me a normal transmission with a torque converter, this is for the birds.
Great feedback, thank you. I hope this last version of the clutch works well for you.
Most educational, clearly explained. Thank you.
In my opinion, it would be very interesting to see a video describing the single dry clutch Magneti Marelli "Selespeed" automated manual transmission, used for example on the Ram ProMaster (Fiat Ducato) 3.0 EcoDiesel.
KEY for this trans: your battery has to be in good shape; less-than produces inferior shift motor operation ('shuddering' complained-of etc.). So half-life to new is necessary (alternator doesn't supply necessary amps at low rpms, where 'shudder' happens) with this trans. NOT A CLUTCH issue but instead Mexican servo motor requirements, or they'll turn later and slower, and you then 'hear about it' :)
That is amazing, I was wondering what that lurch was between 1st and 2nd, turns out it was the engagement of one of the two clutches as the transmission switched input shafts.
Very good video
Thanks !!!!!👍👍👍
Very well Explained with much detail, thank you.👍
Excellent sir, impeccable as always, thank you.
Thanks again!
Fantastic video. Thank you so much for explenation.
+Channa Duminda Thank you!
Thanks Sir for your professional update on this clutch assembly and emfrmation best of luck my friend 🍀
Thank you!
Excellent demonstration, thank you
+Mariano Szklanny Thank you!
A very interesting lesson! Thank you for sharing it. 🙂
John, lots of problems with this DCT in Focus and Fiesta, still on 8 week backorder cycles for the newest seals and friction material. Warranty was extended to 100,000 or 150,000 miles (don't remember which). Lots of complaints on the forums, and lots of messing around to even get in line to have this fixed.
Thank you for the feedback!
We got the same warranty extension150000
Miles when the clutches went out for the 3rd time at 89000 miles we took it in and the dealership said that was only for computer reprogramming. The cost was $2200. Thanks ford, and they wonder why people buy foreign.
Awesome video learning every day greetings from tulua Colombia
Thank you
I've been driving a 2012 Focus with the DCT for 80,000kms now, the Trans control module failed recently, causing it to pop out of gear, we're getting a new TCM now, but as I've done trans work on other cars I was curious to see how it works, just 4 electric motors really do the automation, I find the car is quite conservative with its clutch slippage, probably to prolong the life of the unit, it still has pretty fast upshifts and puts the power down nicely, good stuff!
+Kingsoupturbo Thanks for watching!
It's shocking that Ford uses such low-quality seals in this transmission. Today I picked up my car from the dealership after the third clutch pack in my Focus was installed (factory and two replacements) due to seal failure. It's so nice not having to rev the engine to 3000 rpm to eliminate 1-2 shift shudder anymore. This is the second time I have heard that Ford has used replacement seals of better quality - although I was told the last time the clutch pack was replaced (July 2015) that it should have been fixed permanently.
Thanks for your feedback! Best wishes
Thanks. I was assured by the dealership that "This should be it" for seal failure but I'm not holding my breath...
I've had to replace both clutch assemblies (during a single failure event), The question came up... "What about using the cruise control to down-shift coming down a hill?"
This was actually a great question and needed some testing, I had cruise control set to 45mph over an arched bridge which had a speed limit of 35mph at the exit. coming down the arch of the bridge, i used the cruise control for the rise of the bridge arch and then used the "Coast" button to slow down... it will shift into lower gears to use engine compression-braking.
This should be included in the performance notes.
Had mine on cruise going down a hill got stuck revving 3000
Congratulations, you are very didactic, Thanks a lot for share this great explanation, The DCT is wonderful , I am focus 2014 owner and it work great.
Thank you!
Great video on Ford powershift 2 clutch auto
Thanks for sharing! I believe this is the same transmission as in my 2014 turbo diesel ford mondeo. I spend a lot of time driving it in manual mode as the engine is so ridiculously noisy I prefer to upshift early rather than listen to it. It also takes some getting used to, in that it does not creep forward like a traditional auto when in drive and on heavy acceleration combined with the turbo lag there is a full second of nothingness on every takeoff followed by uncontrolled wheel spin.
Hi, the Mondeo does use a Getrag DCT, but it is a different model that is little stronger to handle the diesel's torque. The model number is 6DCT450/6DCT451. Thank you for the feedback about the operation of the engine/transaxle combination in your car, that second of nothingness would be annoying. Thank you for watching.
Sounds more like error 18
Fantastic work 👌 thank you for making this video!!
Thank you Randal!
It sounds like VW made the correct choice going with wet clutches.
+Jeff K I agree. thanks for watching.
+Jeff K They have Dry ones too.
as well as the shift forks being controlled by hydraulic pressure, as opposed to these strange gear units. I don't like that setup. Cool vid tho
VW don't use wet clutches on all their dual clutch transmissions, when they went from a 6 speed wet clutch in the mark V golf to a dry clutch setup in the mark VI. These have more issues and can burn out and shudder quite easily and were subject to many recalls and fixes.
Gracias por la información, le agradezco y lo saludo muy actualizada de gran ayuda.
Thank you
This is great! I would love to see the NIssan GR6 unit analysis like this
Thank you! I would like to get my hands on one.
Just a plain old school 5 speed manual transmission for me and no transmission problems or clutch problems as operate the clutch property.
Yep, '12 Focus w/5 speed is rare in the US. No probs @110k, 38mpg
John, that was an excellent presentation!
+pfweeks Thank you!
Great video about a p.o.s. transmission. Well done on the detail. 5/5
Thank you, your videos are always very informative. Its always interesting to see how DCTs and ECVTs are competing with regards to fuel economy. Hondas fit (with i-DCD) is quite interesting architecture as it also has a planetary gear.
Thanks for watching!
This transmission has been a huge problem for Ford. If you could get hold of the comparable VW Getrag that doesn't seem the same problems it would be interesting to see the differences if any.
you are a very good teacher
really i like this video i overhauled clutch assembly i did not open gearbox
sukesh punathil Thank you!
Look at the TSB's on these transmission before buying a car with one, just a warning. Not sure if the 2015's are any better but previous models years had lots of problems.
Apparently the problem starts from the seal on the input shaft leaking fluid which gets in the plates, which you sort of seen in your video, whether than was grease or fluid can only guess.
+Only1Truth Thanks for the feedback!
Great great
I wonder how did you cleaned it out the in-house, it looks nice 👌 I took down mine but I couldn't clean it like that...😢😢😢
Thanks for the video very goo general information 👍 👍👍
John, I’d like to offer some professional advice about your microphone use. The mic capsule is picking up far too much low frequency that does not help understanding. It also seems to have too much gain and is overloading its preamp or your interface. These two problems are interdependent to some degree. Let’s start with placement.
Move the microphone so that it is not in front of your mouth but rather to the side of where your lips meet. Keep moving it in that direction until you hear the clearest pickup in your headset. You should hear no puffing of wind from fricative consonants no matter how loudly you make those sounds.
Second, try lowering the gain of the microphone signal about 3-6 db. You should hear some pretty obvious improvement once it is hitting the preamp or compressor after the preamp less hard. Depending on the path your mic signal takes there may be low cut adjustments as well which will make a big improvement.
You do fantastic work and I’d like the largest number of people to enjoy it. All the best, Peter.
Thanks for the feedback!
@@WeberAuto You’re very welcome.
Who cares!?!?!? Your comment is 9 Years late.
@@zapa1pnt As to your second half, oops! I failed to notice that and thanks. As to your first half, 🖕🏽
love your video on how this transmissions work, i really appreciate it, and im gonna ask you if you ever come accross a vw dgs, and do something similar, i will be great, and thank you again for your good work,
I have a VW with the 7-speed dry clutch DSG which mostly works without any drama. The big difference as most are aware is that the Getrag actuators are electric instead of hydraulic as on the VW. I have to wonder that if the next gear is not the one preselected whether the motors are fast enough to change gear without noticeable delay?
And as others are, I'm amazed that they (both) use what appear to be relatively conventional technology for the throwout bearings. And that the actuation mechanism is exposed to dust from the clutch disks which cannot be good for grease present.
Oh, one other item worth mentioning in your fascinating videos, inherent in this design there must be mechanical means to lockout invalid combinations of actions under fault conditions such as being in two odd or two even gears at the same time, or having both clutches engaged. Perhaps that's partly taken care of by the shift cam drums?
Yes, the drums prevent that. Wet dual clutches seem to be the most trouble free. Thanks for your feedback.
Thank you for displaying this.
very interesting video! Thanks for uploading!
Thank you!
my first video that i watched of yours was the Manuel transmission operation. may i ask why do you use a wheel chair??
06CHEVYDURAMAX Muscular dystrophy is getting worse. Thanks for watching.
Amazing teaching! Congrats.
Thank you!
Absolutely amazing. I think it's a bit wrong to have special tools to work on this as they must be very expensive for garages to of buy them which would surely bump up the price of servicing and any repairs.
Thank you! I agree
great video, thx. i would love to see you take that dual clutch apart and let us know how it works.
Thank you for the excellent video.
Thank you!
When talking motorcycle (sequential) gear boxes, we call those grooved cylinders that control the shift forks "shifting drums".
Thanks, I found out later that Ford does too.
@@WeberAuto Sorry, I din't notice the date of this video.
BTW: Great videos, I just found them this week, and already seen a number of them. Thank you.
@@jorgeferreira6727 Thank you
William sir very good. Very informative video .thanks alot
congratulations, I really enjoyed this class. very well explained! I'll follow, I'm from Brazil🇧🇷
i have 2014 focus that was slipping when i started off, now its at the ford deal getting clutch assembly replaced, i just hope it fixes the problem, ford has had major issues with them
