Ford Dual Clutch Transaxle (DCT) DPS6

Unlike regular manual transmissions, dual-clutch transmissions are manual transmissions that are controlled by a Transmission Control Module (TCM) computer. To the driver of the vehicle, these transmissions operate like an automatic transmission.
Dual-clutch transmissions use two clutch disks, two pressure plates, two release/apply bearings, two clutch forks, and two input shafts. One input shaft feeds power to the odd-numbered gears, the other input shaft feeds power to the even-numbered gears.
Other vehicle manufacturers (BMW, VW, Volvo, Renault, Nissan, Ford, Honda, Mitsubishi, Lamborghini, Porsche, Fiat, Chrysler, etc.) use DCTs in some of their cars; some are used in high-performance applications due to the very quick-shifting speed and lightweight.

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.

[@WeberAuto]

+massltca Thanks for your feedback!

[@peteryates9153]

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

[@trcs3079]

​@@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.

[@WeberAuto]

Thank you

[@setSCEtoAUX]

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.

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!

[@marthagoodall7329]

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!

[@6speedguy845]

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.

[@alanjm1234]

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.

[@michaelallen2501]

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.

[@jameskuberski9621]

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.

[@WeberAuto]

[@thomasedwin1]

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.

[@WeberAuto]

+Thomas edwin Thanks for your feedback!

[@chrisw1462]

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.

[@torqueunlimited3522]

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.

[@dougtomich5093]

i heard there is an extended warranty on the computer.. ~150k miles (not recall though)

[@dougtomich5093]

[@nasmitty5261]

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.

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.

[@WeberAuto]

I am sorry to hear of the troubles with that car. Best wishes

[@PhilipGragg]

Sorry if this was answered in another video, but why are the gears slanted? I noticed this is the industry standard (I think... I've not seen it another way). Is it for strength, or is it just more efficient? Or would it be for wear reasons? Thanks!

[@WeberAuto]

Philip Gragg Hi, helical cut gears are quieter than straight cut gears, they are also stronger than straight cut gears because of their increased tooth contact surface area.

[@joevignolor4u949]

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.

[@WeberAuto]

Good point! Thanks for the feedback. Wet clutch dual clutches seem to be the better method.

[@joevignolor4u949]

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.

[@arahtson1]

Hey John; great video demonstration. Just bought a second-hand 2012 Ford Fiesta Sport for my wife in Thailand and later learned about issues with this transmission; however, everything appears okay. They had problems with the two input shaft seals leaking oil into the clutch housing and they were modified. The old type are colored black and the newer ones are brown and seem to have solved that problem. As you stated, the dual clutch assembly has also been modified. This is a great small (second) car with good acceleration and gas mileage; hopefully the previous transmission problems have been laid to rest. Ford also state that renewal of the transmission fluid is not required! Just had mine changed at the Ford Dealership in Thailand; it only requires two quarts of Motorcraft Merchon V, so why not change it!

[@eugenenault4935]

[@SexyAndlKnowIt]

Can you explain the why the clutch slips and causes a shudder concern with this design? The first batch of these DPS6 transmissions have a leaky input shaft seal and the clutch gets contaminated by the dual clutch fluid. These clutches get replaced every 5k-15k miles even after the input shaft seals get replaced.

[@universaltransmissionspeci5103]

One question: Exactly which direction are the 2 gears supposed to be positioned before the cover is assembled?

[@WeberAuto]

+Universal Transmission Specialists Great question. I don't recall, but it is in the Ford service information. There are notches cast into the cover that prevents the gears from being installed incorrectly. If I remember correctly, the TCM has to learn their current position with a scan tool command. Thanks for watching!

[@cxdrive1]

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!

[@Kingsoupturbo]

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!

[@WeberAuto]

+Kingsoupturbo Thanks for watching!

[@kelblueskies3937]

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.

[@paulaxford6754]

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?

[@WeberAuto]

Yes, the drums prevent that. Wet dual clutches seem to be the most trouble free. Thanks for your feedback.

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.

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.

[@svbeattie40]

When you come to a stop, is the clutch automatically disengaged when the brakes are applied?

[@WeberAuto]

Yes

[@jaymoney4265]

Great video! I'm just confused as to how the tcm knows what position the shift forks are at, upon initial start up? Does the tcm just automatically shift the fork to 1st gear everytime the vehicle is started? How does it know if it's already there, IE battery disconnected in first gear, and vehicle shut off, or is there a sensor that transmits data from each input shaft, or shift fork, to the tcm?

[@glenbjack]

Kelly, what would you say is more complicated this or an automatic?

[@WeberAuto]

Automatic

[@BehzadEghtesad]

Thanks for great explanation. do you know if we swap the TCM with new or used , do we need to programming it by dealers or special scanners?

[@alanjm1234]

You can't swap the TCM with a used one from another car, as they are VIN coded. If you replace with a new TCM you need to input the VIN. You'd also need to run clutch and shift fork learning programs. An OBD EX adapter (about $50) and a laptop with FORSCAN software (available free) is all you need to do this though. There's a FORSCAN forum with lots of information about the best adapters etc.

Hello everyone, this US clutch problem has been around for some time now. Here in Brazil it is recent. How is it solved out there? Are the dealers changing the parts? Here in Brazil it takes more than 5 months to change the clutch. Is there a queue in the US too? How's the issue out there? Thank you

[@WeberAuto]

Yes, a clutch change and software update are the attempted fixes. We have the same problem. Thanks for your feedback!

[@ajsaenz2295]

Is there a part number for the 2 specialty tools required to remove/install the Dual Clutch?

What is the maximum oil temp which this gearbox can handle? This gearbox is used in Renault Clio RS and reaching up to 95°C (200°F) while driving on track is pretty easy so I'm just curious if Renault has put box in their sports car which can handle track use.

[@WeberAuto]

+Mateusz Nieckarz Good question! I do not know the answer though, sorry. Thanks for watching!

[@torqueunlimited3522]

Is that throwout bearing has any balls on it, how do they minimise the friction? Seems like complex design. Seems like it doesn't have any balls or needle type roller in it. That may cause more friction on pressure plates.

[@ismaelalvarado706]

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 👍 👍👍

[@tonyjordan1320]

My niece had to have her dual clutch replaced last year, did they have to dump the trans. fluid when they did the repair or should I still change her fluid out for preventive maint.???

[@TheRock0232]

Great video. Do you know if the seals for the cv axle shafts can be changed from outside without removing or disassembling these transmission. I have one leaking and can't find any info. Thanks

[@WeberAuto]

They cannot be changed without removing the shaft, sorry.

[@davidwhipple3832]

I'm just curious. Say on cruise in a steady speed in 5th gear in the computers anticipating my next year is going to be 6. Then suddenly I press hard on my accelerator calling for a downshift in the four. It seems like that would cause quite a delay on the downshift. Or maybe I just don't know what I'm talkin about.

[@davidwhipple3832]

Sorry for all the typos speech-to-text and all that

[@runforit420]

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.

[@WeberAuto]

Thanks for your feedback! Best wishes

[@runforit420]

Thanks. I was assured by the dealership that "This should be it" for seal failure but I'm not holding my breath...

[@s2k672]

Excellent demonstration as well as presentation of DCT. Thanks

[@peterbustin8604]

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]

Thank you! I agree

[@MMWA-DAVE]

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.

[@WeberAuto]

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.

[@erik_dk842]

Sounds more like error 18

[@BehzadEghtesad]

Hi, Thanks for great explanation. do we need to do clutch reset prosessure for used clutch too? i swaped my clutch / forks with used one, no i don't have any shifting. P0805 and 6 also. but before the car was driving.

[@jamyspradlin8504]

Thank you John. Great explanation of assembly and operation of this transmission.

[@jeffk464]

It sounds like VW made the correct choice going with wet clutches.

[@WeberAuto]

+Jeff K I agree. thanks for watching.

[@GEMC98]

+Jeff K They have Dry ones too.

[@tim9817]

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

[@michaelclark3192]

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.

[@questionreality6003]

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' :)

[@paullassen9336]

OK, I didn't catch the name of the gear assembly that the TCM uses to control the shift forks But is there a alignment mark between the two ? I can see if the gears were not placed to synchronize with one another when ramping the forks in and out of desired gear. It could cause one gear to engage before another is free and vice versa. Essentially causing a shutter or jerking.

[@WeberAuto]

The gears are called Shift Drums. There are not alignment marks, they just have to be installed in the neutral gear position. The TCM will then learn their positions with a scan tool function. The shuttering or jerking is because of the clutch disks being contaminated, or dirty, or glazed, etc. Best wishes.

[@noelconroy3647]

Thanks Sir for your professional update on this clutch assembly and emfrmation best of luck my friend 🍀

[@WeberAuto]

Thank you!

[@artysanmobile]

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.

Great video thanks. Really helped me understand what's going on in my transmission.

[@srdporter]

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!

I have a P2837 shift fork "B" position circuit range/performance and a 287B shift fork "A" calibration not learned. There is no reverse. 50,000 miles. I swapped shift fork actuators around and still the same codes and no reverse. Do you have any suggestions?

Disconnect the 12V battery for a few minutes and then reconnect it.

[@abz124816]

How do you prevent the engine from stalling when you are in first gear and stopped at a light? Is there a torque converter involved?

[@WeberAuto]

+abz124816 Hi, there is not a torque converter, The clutch discs are automatically released at when you are stopped.

[@abz124816]

+WeberAuto how does that happen without stalling the engine or riding tge clutch?

[@WeberAuto]

+abz124816 Hi, just like a manual transmission. Think of it as having a computer stepping on the clutch pedal for you when you stop, and releasing it when you need to accelerate. It is all computer controlled.

[@evdemiguel]

[@criminalbrewing5509]

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.

So what will make my car jerk so badly? Is it the flywheel or the clutches? Also something behind the firewall is knocking after said jerk in my Ford Fusion 2014 AWD model 2.0 liter. I think it may be the same transmission that is in the Focus if not both of these transmission have some serious problems. The car idles funny now after taking it to a Ford dealer is when I started to notice these problems.

[@WeberAuto]

+The Trillion Dollar Gods Hi, I don't think the fusion has the same transaxle. I would take it back to the dealer and let them know what has happened. Thanks for watching!
