Man it blows my mind how much engineering goes into things we use and take for granted every day. It's like a masterpiece of machining and technology. And it's just an automatic trans on an average car
Gary,I really appreciate them as well; they are challenging to work on in some ways, but always interesting. The precision that goes into CVT variators and management of the hydraulics in particular is amazing. Thanks,Matt Johnson
Yeah if you work in engineering you look at everything differently. So many things people take for granted there were several engineers busting their asses to get that thing to work.
Transmissions are, short of the engine, the most critical component of an automobile: no working transmission, no forward movement. Modern society would cease to exist without incredible engineering 🌟
I will apologize up front; I am a UA-cam beginner and have marginal at best video editing skills. We work on a lot of interesting transmissions; CVT's, DSG's, Hybrid Drive systems etc... This is a basic teardown on a Jatco JF011E that we thought might be interesting. We work on a lot of CVT's in general and most of the late model Jatco units are very similar, but have some variation in common failure points.Thanks,Matt
Kevin,The unit itself would not have an issue with supporting the auxiliary cooler, but the type of the primary cooler can be the issue. Many of the JF011E's have a cooler which bolts to the CVT and coolant is piped to it. In this case there is not a way to access the CVT fluid and port it to an auxiliary cooler. Thanks,Matt
I am amazed at the level of technology we (as a species) have achieved. I watch videos like this as a hobby,; I know very little about modern car technology. This guy making the video is just like a heart surgeon. [And I am glad that I drive a Honda with a Honda CVT, not a JATCO CVT.]
It depends on the extent of the damage. If the sheave surfaces or belt are damaged at all from slipping, or the internal bearing grooves have any deterioration then they would need to be replaced. If the damage is limited to the pump flow control valve, bearings etc... then the pulleys and belt may be re-used as they do not generally fail unless another component causes them to go down.
Enjoyed this video. Was curious to see what these look like on the inside. I had a 2010 Nissan Cube SL with all the factory goodies on it and the CVT transmission. I liked that car a lot. That CVT got all the available power (all of about 122 hp of it I think) from that little motor to the ground quite well and gave good fuel economy (I got 29 to 32 in town and 30 to 33 on the highway). It was a perfect city puddle jumper and decent on the Highway. Loved the inside roominess and the small foot print it had for parking. I loved the smoothness of the transmission and the seamless gear ratio changes. It was always at the right gear ratio no mater what the speed and grade. I had that car for almost two years until it got rear ended and totaled. The car that hit it looked worse than the Cube after the hit. It was totaled as well. And it was about 1400 pounds heavier than my Cube. I had zero problems with that car until then.
I have a 2010 cube, and my wife has a 2014 cube. Between the two of them, they've traveled more than 190,000 miles -- 134k on mine. The CVTs have been reliable so far, and yes, very smooth and efficient. But we do have their fluid changed every 30,000 miles at the dealer. It's about $150, and at the rate we drive, it happens about every other year. Worth it.
Just got talked to a Mitsubishi technician about my 2014 Mirage CVT. He was honest. He said most CVT only hit 150k miles on them if theyre paired with underpowered engines (less than 100 hp) and a light car weight (no more than 2400lbs). And you have to drive them slow! No punching it, just rolling it. Change that cvt fluid every 30k miles is critical too with OEM oil. You adhere to these variables and the transmission has a good chance of lasting 10 or more years.
kylemas2005 .... you’re exactly right, CVT’s work better in under powered hybrid vehicles, very poorly in anything else. They are still junk. I want the manual trans back! It keeps drivers in better tune with the car and the road.
@@Toguro-oy3ld My Mitsubishi Mirage isnt a hybrid but a 1.2L 3cylinder with 74 hp. I actually get better mileage than many hybrids. Even the little Nissan Versa is too heavy at +600 more lbs and too much hp (over 100 hp I believe) to keep these little Jatco CVT7 from burning out. Ive talked to a number of transmission specialist and they all say the same thing. "Mitsu CVT programing is much more reliable than Nissan. Keep your fluids correct, dont dog the CVT out and there is no reason a Mitsu designed CVT cant hit over a 150k miles. The fucked up thing is Nissan owns a big share of Mitsubishi. One would think their designers and engineer from both firms would cross evaluate why one is working and one is plagued with problems? Still though, give it another 5 years and the CVT issues will be engineered out. This type of transmission is here to stay.
This mechanic knows his stuff, pure muscle-memory right there. I'll be going back to a manual when the economy picks up. Sadly, I had to buy CVT trash recently. Getting hard to find manuals as so many drivers want to steer lounge chairs & not drive a car. Didn't want to go into debt buying a new car, so I bought 2nd hand with cash due to bad economy.
Thanks for posting I did not know about CVT when I bought my new 2019 nissan Quashqai. But I learn a lot since then it just Unbelievable, At first I felt it was like a ticking time bomb. I could not understand why would Nissan install these CVT in there cars When they fall there so much damage to the CVT that it would cost more to repair it then replace it. And it all to do with the massive amount of heat these CVT transmission generate. causing an abrasive carbon build up. in the CVT fluid. I read that before the first nissan Jatco CVT went into production nissan tested them for five years, by driving them around the clock 24 hours a day, in city traffic, up and up and down the steepest hills they could find. After the five years were up, they found there were no problems what so ever. with the CVTs. But the thing is ever few months the cars CVT were taken out taken of the teat cat pull apart and examined. They found almost no wear and tear. But the thing is that ever time they examined the CVT they also change the CVT fluid. So they did not see the carbon build up in the CVT fluid. And the damage that it was doing. But they know now that the problem with these CVT is the small amount of CVT fluid and the heat from the contact points on the cones and steels belt that burns the CVT fluid this creates a build up of carbon in the the CVT fluid. that The Carbon in the CVT fluid It is a mild abrasive and if it not removed will effects ever thing in the CVT including a small return valve that has been shown is prone to failure. So the main cause of failure in these CVT are cause by a build up of carbon in the the CVT fluid. It been found now that just by changing CVT fluid regularly as some one on here once said Around about every 30-40,000 miles. the CVT should out last the life of the car, that it was installed in .It not an hi-tect operation to change it you can do it you self easy. but it much mach the same amount of CVT fluid that came out of it.
I was a mechanic for 18 years between '82 and 2000. Great video, thanks. These CVT's are well after my time, and I find the concept horrifying. In my day, we had the "Hondamatics". And I suspect one thing is shared between those and these new CVTs - the driver, no matter how much you try to educate them, will never adapt to the altered driving experience.
Something in the power valve assembly broke on my automatic 95 del sol recently. It ran beautifully for 226,000 miles so I can't complain much (the car was ";rebuilt" after being bought at an auction as a totaled car). You can say I've been a Honda fan for a few decades now :)
Thanks for the effort on this video, glad I found it. I deal with these transmissions so much but never take them apart more than replacing the pan filter. Anything not under warranty gets a junkyard trans, which always seem to work out. The metal on the magnets and on the pan, and the dark yellow color of the fluid is consistent with 80k+ with never having any fluid/filter service. At training, I took one of these apart like this and put it back together once. A big point they made was that if this belt was ever allowed to slip at all, it would would need a belt/pulleys/bearings because it would soon lead to the damage shown here. I've done a few transmission videos myself, and it's tough to make it turn out to be an interesting video. Thanks for doing a nice job.
Finally i found this. I have a Renault fluence (Korean made) 2012. Privilege 2.0 liter engine mr20 Nissan engine with the same cvt transmission. I have changed transmission oil 2 times since new, and the hardest thing is to find the paper filter replacement part inside the oil cooler. (Nissan part number 31726-1xf00) Renault dealer thought it was a bearing , when i asked for it in the parts catalogue. Great vid and very helpful. Thank's for it.
@@rollandelliott they don't show it. Look at this video. second 50 shows the fiter housing..(how is your portguese?)ua-cam.com/video/74cT8ykwclM/v-deo.html. Hope this will help. This filter is the same for Nissan sentra 2.0 2010 cvt transmission.
Jatco OR Nissan has been making transmissions systems since 1970. So, it is unreasonable to be said that CVT is the worst transmission system. I do believe that the CVT needs regular oil change as recommended by the manufacturer. The same case for DSG by VW. Moreover, people still think that transmissions systems do not need changing oil and oil filters.
The manual transmissions are simple, efficient, reliable, with low cost of maintenance. Conclusion? People here in US buy automatics, to the point where the OEMs stopped oferring manual transmissions on most models.
@@bkucinschi Manuals are exasperating on city traffic and hellish on steep streets. That's why sensible people buy autos. The price to pay is higher costs if and when they fail. Manuals are bound to disappear in the future, however, as well as traditional autos, CVTs, DCTs, etc. Electric motors don't need gearboxes except for a simple reduction gearset. But I'm sure most garages wouldn't be able to fix any of them, as it is nowadays with most components already. Swapping shops I call them.
@@Gavichap : I lived in US for 20 years now but I am originally from Europe, where (at least at the time) the grand majority of cars had manual transmissions. Once you get used to that, driving in hilly terrain was no big deal. The biggest deal was to change the clutch. Last year I replaced the clutch myself to my old trusty 2005 Toyota Tacoma, took me one weekend but I had a great feeling of accomplishment. If a manual transmissions really breaks down, you can get one pretty cheap from a junkyard. You can get an automatic also, but it's much more difficult to change and adjust, and a lot of time the junkyard autos are shot too. My truck it's 200,000 miles now, and its 5-speed manual works perfectly. Yes, people buy vehicles with automatic transmission... that's fine, they will have to buy them more often... keep the auto industry in business. Electrics are coming, but they will take a while to generalize, the power infrastructure is not there yet.
@@bkucinschi Many people including me cannot stand manuals in city traffic and on steep streets at standing starts, that's the ratio of buying an auto. It's just tiresome (and distracting) to have to costantly drive with one hand on the wheel and the other on the stick. That's one reason why over here pedestrians are run over on the zebra crossings at maddening rates (the latest just yesterday, dead): they drive in 4th as long as they can. Auto gearboxes don't come from Mars and they can be fixed by dedicated specialists, like engines (modern ones are as complicated as you can think of). Pity that most of the times mechanics are as hopeless and lazy as 5th grade brats. I fixed the 'automator' on my jurassic Fiesta myself with info I found on the internet with a DIY tool as simple as a pencil. And I know very little about mechanics.
@@Gavichap : Automatics are certainly simpler to drive, and very convenient in congested areas. My point was that all those advantages come at a cost. Sure, there are handy guys who are able to maintain and repair an automatic transmission, but most people can't so they finish up with a significant financial burden. In USA a failed transmission (out of warranty) means, most of the time, that the older vehicle is junked. So, spit the money or get in debt for a new one. For the traffic conditions in my area a manual transmission is no problem. I'm not a rich guy, so for me a manual vehicle equals financial comfort.
Blue Moon the main issue with CVTs failing is because companies keep putting them into heavy and medium - high torque cars. Something these transmissions definitely cannot handle.
Mr. Nunna that’s where they are leading us though. Eventually it’ll be damed hard to find a standard or traditional automatic. They will improve over time, but for now I agree with you. Avoid the headache.
Do not buy a car with a JATCO transmission !!!!!! Today, JATCO has become one of the biggest supplier of CVT, and products from nearly every auto maker have used Jatco transmissions, with the notable exceptions of Honda Motor Company, who makes their own transmissions, and Toyota Motor Company, who has always used transmissions made by Aisin, a subsidiary of Toyota.
@End OfTime no, subaru cvt is built by fhi. Audi and subaru cvt is assisted by luk technology. In April 2009, another CVT using technology made by LuK was introduced: Fuji Heavy Industries Ltd. unveiled its MY2010 SUBARU Legacy as well as the MY2010 SUBARU Outback at the New York International Auto Show. Figure 2: FHI/ SUBARU’s longitudinal AWD-CVT LineartronicTM [3] The drive train combines SUBARU’s horizontal-opposite (HO) engines with LineartronicTM, a brand-new longitudinal, highly efficient AWD CVT with torque converter as a start-up device (fig. 2). LuK supplies chains and guide rails to FHI and supported the pulley system development.
Fluid, fluid, fluid, fluid, fluid...………….. Did I mention changing the fluid? Also, heat is the enemy of any automatic trans; even more so with a CVT. A cooler is not a bad idea, either.
I always tell people to change the fluid and install a trans cooler but I am usually told that they have a "warranty", or that the fluid is good for "life". It's not expensive to do a drain and fill every so often on a vehicle. I was also told that car company's would put something in a car that was worse than the previous years. Some people listen, some don't.
I was told by Nissan that a 6 year or 84,000km fluid change is mandatory for these transaxles - otherwise they tear themselves up not too shortly after. Still not a fan of these transmissions - they are real smooth but Nissan programmed in "shifts" which really negates that feeling in the newer cars.
If you drive normal with light accelleration it still gives the smooth accel without the shifts. I've gone from 25-60 without the RPM changing more than 50
It has not nissan will fix the car but I must say I have had a good run with my 07 Altima it has 288.000 miles everything I owned. Before was a lemon! I really want a Maxima 09 man take a chance don't listen to people!
@@imlamar2011 just leased a new maxima for my wife. Great car. Best part is they throw in all maintance for life of lease, no worries. Get a kick when some say I got a million miles on this car or that car. When you get older you deserve a new car with no worries....
Most Nissan owners are perfectly happy with their cars, but obviously the people screwed over by their transmission make a bigger stink than "yeah, it's still running" 😛 79k miles on my 2016 Versa Note and it continues to run well, I enjoy driving this little car.
Powertrain warranty is 5 uears 60,000 on nissans now. Almost all the horror stories put them going out between 20 and 40,000, so buy one cause everyone else whines when they only get 180,000 miles which is on par with alot of regular auromatics. Regular fluid changes and it will probably last longer than youll wantto keep the car anyway
Is this what happens when you don't change the transmission fluid on a regular basis and/or change it too late and the transmission breaks later on? * I own a 2014 Mitsubishi Lancer ES with a CVT, and I'm potentially facing this problem sooner or later...
I saw one where the shaft had worn out where the banding sheave bearing had split in half and the sheave jambed up blowing the metal bands all to hell. The shaft material is much too soft. They only use 3 grooves for those bearings. The transmission had 180k on it. The belts or bands didnt fail until the pully or sheave rotated and locked up. All hell broke loose then.
If there was ever a case to be made for electric vehicles with me it would have to be the simplicity of a vehicle with no gear box and no complicated engine/ maintenance. Hello future.
Jb Nissan makes the worst electric vehicles. The Nissan Leaf is total junk because the batteries are air cooled. You would be better off with a Chevy Volt.
What causes these failures? I have a 2013 sentra with a jatco cvt that judders on the first acceleration starting cold and I'm afraid the pulleys are all scratched up like this one is. Dealer won't help unless it throws a code, and by the time it does it's already too late anyway
I have the same transmission in my 2014 Mitsubishi Rvr (Outlander sport) and the car drives fine but every now and again at hwy speeds it will start to whine and the car tells me to slow down and that the transmission is overheating. Should I add a oil cooler or is the transmission slowly dieing? Thoughts?
I have this transmission in a 2008 Lancer. There is a clicking noise that sounds like a bad inner CV axle but I've been told that the noise is coming from the transmission. The axle boots have been leaking and the noise is only heard when coasting with the engine running. No axle noises with the wheels cut and no noise coasting while the engine is off. I've been driving it this way for quite some time and the transmission isn't slipping. I just did the second transmission fluid change (80,000 and 140,000) and the mechanic showed me the pan on request. The fluid was of good color and there were no metal shavings on the magnets. What could this noise be? Should I worry about it or just keep driving it that way? Could a bad inner CV axle be the culprit?
Many of these don't have a dipstick and are sold as lifetime fluid. You can change it.. but most people don't know about cars.. and just do what the manufacturer tells them.
I knew about the Jatco reputation. Still, I bought a car with Jatco CVT. Now, it has 80.000 km, no problems at all, 1 regular transmission fluid change and hoping for the best. I love the tranny up to now (until it breaks). Mitsubishi is a bit smarter than Nissan using these CVT transmissions. I have a Mitsu, so that gives hope.
Mine is around 155k miled on 2011 lancer. Still good,until now i dont know there is oil filter and cooler cvt,i might service/replace it later..i usually change fluid around 50k km interval and using the oem mistubishi cvt j4 fluid

Hi, I was wondering about the part where the audio cut out regarding the oil pump. Is it true that the main failure point of these jatco Cvts is the oil pump? If I simply changed the oil pump and left everything else as is (making sure nothing else was damaged of course), would that be enough? I’m asking cause even doing a full rebuild myself is still $1000 with all the parts and tools involved.
My CVT transmission on my Mitsubishi Outlander 2008 doesn’t shift gears automatically while on drive (D)mode it remains on 1st gear. When I use manual mode (+/-) gears shifts smoothly. Do you have an idea how to solve this issue ?
Honda makes their own automatic transmissions. The transmission factory is located in Russell's Point, Ohio, a town about 60 miles northwest of Columbus.
I own two vehicles both with CVT transmissions. Of the two I trust the Italian one more than the German one. I should probably move to a house near your shop.
Common weak point on these is the flow control valve in the pump, when they wear the pump loses pressure and the pulleys can't stay as tight causing the belt to slip. This will result in marked up pulleys. The pulleys are super hard though and can probably be cleaned up like new.
I have a 2015 Altima feels like it’s slipping under light acceleration. Do these throw engine lights when they go bad? Is it possible to just change the fluid and it’s good or am I toast already?
Curiosity only, about how much would it cost to remove, rebuild and reinstall that thing? Thank you in advance for an answer and for an interesting video.
Robin, They really vary by what vehicle they are in and what has failed on them. In looking at our most recent few JF011E's that we have had to re-build, they have varied from about $2500.00 to $4000.00. The condition of the pulley sheaves and shafts, differential and transfer gear (and any bad electronics that may have failed) can really vary the price.Thanks,Matt Johnson
I have a 2011 Mitsubishi Lancer, and my cvt has a loud whine and I get a lot of over heating issues after driving on the hw for more than an hour, the car has 130,000 miles, changed the trans oil 30k miles ago the over heating stopped for a while, the car also feels like a “slingshot “ I’ll give a little gas than the car pauses than jumps to speed, what could be the solutions for that ?
Very interesting video. Have a question for you sir. My cvt trans is leaking from where the torque converter sits but not sure where it’s leaking from. Is there a seal that is easily accessible to replace or would it be the torque converter that’s leaking? I’m fairly new to looking at cvt trans I’ve only broken down regular 5/6 speed manual trans so far. But I really appreciate this video.
Matt, I have an 08 Lancer that makes a whining sound only when moving. It sounds like a loud electric motor. When people ask; I tell them it's the "Electronic Turbo". Road sound usually blocks it out over 35mph. I bought the car months ago (knowing about the sound) and immediately drained and added new CVT fluid, but no change. I have put many miles on since and have had no problems. I lifted the car and let the wheels spin while running; I am fairly confident the sound is coming from the CVT. What do you think is causing it?
Ankly,It sounds to me like a bearing. It would be a good idea to drive the car on a free wheel hoist to make sure the noise is actually coming from the transmission. Unfortunately, none of the variator or transfer gear bearings can be serviced without removing and disassembling the unit. I would also expect to see a heavy metal content on the magnet in the pan if this is a bearing issue.Thanks,Matt
Change the cartridge filter and o-rings in your CVT cooler housing, which is below your battery tray. The battery tray can be removed to access it. Then change your CVT pan filter and gasket as well. Use Eneos or OEM Mitsubishi CVT fluid and original parts only.
HI...i have same transmission and it has whining noise from the transmissions. While driving I can hear the that and If I drive car on down hill with out starting the engine that time also noise coming. What could be the problem... Can you give me some idea... Thanks.
Rajitha, Whining on the Jatco CVT's is usually one of 3 things: Low CVT fluid level, a sticking pump flow control valve or a pulley bearing starting to fail. Thanks, Matt
I'd never buy a vehicle that has a CVT Transmission. They never seem to last very long. My friend is on his 3rd CVT transmission in his, I think it's a 2015 Nissan Sentra? That car is so weak with that transmission, the engine nearly red lines on hills that my. civic will cruise up at 2000 rpms. On a flat road I guess a CVT would be ok? There's a lot of hills in my state. I just think CVT is a poor choice for an area with a lot of hills. His car is on its 3rd transmission before it even hit 100k miles. Those things are a major piece of crap,not to mention that they're really expensive to fix. I'd never buy one.
The mileage on any of these machines doesn't matter. The way YOU drive does! CVT's are "economy" transmissions, it's not a Ferrari so don't drive it like one. If your MPG is NOT 28 or greater, you're doing something wrong. Like firearms, it all depends on you. It is NEVER the machines fault, it's the operator.
It says it's the operator's fault. If you're consistently avoiding highways then it's still not the machines fault. It's you! It does say that right? Or am I blind?
After I purchased our 2014 Subaru Forester, I only learned from You Tube vids in 2017 that our CVT IS A JATCO. We have 75K on it, but I started doing drain n fills at 60K because I know oil does not last forever. Subaru states not to break thexseal on them as "they are gaurenteed for LIFE". Whose life anyway? Warranty, thats it. So, between many Subaru blogs, my independant mechanic, I am currently flying in the face of what Subaru recommends. Same with engine oil. Maintenance manual states 7500 miles, i change mine at 5000 miles. Differential was recommened to change at 60K, my mechanic said 50K is about as long as they would go. So I am coming up.on my 3rd drain in fill. I am concerned as the color at the first drain was beige, the second was more amber. Any thoughts?
@@robertweber3140 I don't think that the Subaru CVT is made by JATCO. According to WIKI (ok, i agree it's hard to find a legit source of information on the internet sometimes), Subaru's CVT transmissions are named Lineartronic and are made by Fuji Heavy Industries who is Subaru's parent company. Looks like the previous Subaru automatics and some of the manual transmissions were "JATCO designs adopted to Subaru specifications."
Thanks for the video, but the sheaves and belt don't seem premium enough for the load placed on them. Some CVT are worse than others, just like you should not buy a ford which has DPS6 dual-clutch.
Great video! I have a 2010 Nissan Maxima. Would you recommend dropping the pan and replacing the filter and fluid like on a conventional auto? If yes, any tips?
TommyMacDaddy1 I recommend a drain and fill/pan drop every 30k miles or having a Nissan dealer read the deterioration rate using Consult. Although a dealer costs more, I recommend only having the dealer do the transmission service because they’re such a sensitive transmission and can typically only run on Nissan’s genuine CVT fluid which happens to be NS-2 on my 2010 Altima.
What would cause a cvt to delay engaging into the next gear when getting up to highway speeds? My rpms just start screaming and the next gear never comes until I drastically let off the accelerator
We do get quite a few customer's referred by dealerships in the area, and Nissan USA has asked me to assess some of the pulley assemblies that they have coming available. However, they have not had the proper sku's that I have needed ready yet, so I can't speak to their viability.Thanks,Matt Johnson
is it worth rebuilding these cvt trans....and how much do you replace while in there? also how many hours to remove/rebuild/reinstall one from the average vehicle 32hrs labour?
We repair or overhaul a lot of CVT's and build each unit independently. The prices vary widely. In-vehicle repairs can be relatively inexpensive, often under $500.00, but overhauling and upgrading the unit in most cases is a minimum of $2000.00 (with removal and replacement). They can certainly get much more expensive depending on the unit, the vehicle it is in and the extent of the damage. Variator/ sheaving, pump, transfer gear etc... damage can drive the price up quickly.
2000 isn't bad, that is inline with a traditional automatic, I know locally, we don't have any shops that will rebuild CVTs, and the independent shops won't even do R&Rs on them. Dealers will only replace them with new units to the tune of 8-10k depending on the car.
The whole thing is the entire problem. People should get together and file a major lawsuit against CVT manufacturers and totally ban CVT from being used on automobiles.
given the absolute horrible experience I had with Kennedy Transmission, I would never recommend them to anyone. Took at 1998 Accord V6 in to the Blaine location and $3600 later and 4 failed attempts later to correct the issue, sold the car with 100K on it. They rebuilt the trans at 89K...
As much as I hate to say it, AAMCO at least down where my dad lives is the best in town, they rebuilt his 99 Continental tranny back in 2004 for $2400. It was covered under the extended warranty he got from the credit union which more then paid for it's self, but he keep the car for 11 more years and never had a single issue with that transmission again. My older sister destroyed that poor car, but the tranny was still running strong all the way to the salvage yard.
Chris Cook INVECS ECU and the Mitsubishi engines equipped with this transmission makes less than the maximum torque limit of this transmission, which is 220 lb.ft.
Chris Cook Yes, but I still think it would have been better if they used a 5 speed automatic. Mitsubishi used this transmission for fuel economy but I don’t think it matters when it gets 26 mpg on average daily driving. A manual transmission is still better imo.
Man it blows my mind how much engineering goes into things we use and take for granted every day. It's like a masterpiece of machining and technology. And it's just an automatic trans on an average car

Kennedy Transmission, CVT & Auto great video. It accomplished what you thought.
A question please, will the fluid pump in this type CVT support adding an additional oil cooler?
Kevin,The unit itself would not have an issue with supporting the auxiliary cooler, but the type of the primary cooler can be the issue. Many of the JF011E's have a cooler which bolts to the CVT and coolant is piped to it. In this case there is not a way to access the CVT fluid and port it to an auxiliary cooler. Thanks,Matt
The video was great good job 👍
Do AISIN make better transmission (especially CVT) than JATCO? Thanks.
I am amazed at the level of technology we (as a species) have achieved. I watch videos like this as a hobby,; I know very little about modern car technology. This guy making the video is just like a heart surgeon. [And I am glad that I drive a Honda with a Honda CVT, not a JATCO CVT.]
THANKS BUD
Great video, but what are next steps to fix it? Replace belt, variator and bearings? Thanks!
It depends on the extent of the damage. If the sheave surfaces or belt are damaged at all from slipping, or the internal bearing grooves have any deterioration then they would need to be replaced. If the damage is limited to the pump flow control valve, bearings etc... then the pulleys and belt may be re-used as they do not generally fail unless another component causes them to go down.
Enjoyed this video. Was curious to see what these look like on the inside. I had a 2010 Nissan Cube SL with all the factory goodies on it and the CVT transmission. I liked that car a lot. That CVT got all the available power (all of about 122 hp of it I think) from that little motor to the ground quite well and gave good fuel economy (I got 29 to 32 in town and 30 to 33 on the highway). It was a perfect city puddle jumper and decent on the Highway. Loved the inside roominess and the small foot print it had for parking. I loved the smoothness of the transmission and the seamless gear ratio changes. It was always at the right gear ratio no mater what the speed and grade. I had that car for almost two years until it got rear ended and totaled. The car that hit it looked worse than the Cube after the hit. It was totaled as well. And it was about 1400 pounds heavier than my Cube. I had zero problems with that car until then.
I have a 2010 cube, and my wife has a 2014 cube. Between the two of them, they've traveled more than 190,000 miles -- 134k on mine. The CVTs have been reliable so far, and yes, very smooth and efficient. But we do have their fluid changed every 30,000 miles at the dealer. It's about $150, and at the rate we drive, it happens about every other year. Worth it.
Just got talked to a Mitsubishi technician about my 2014 Mirage CVT. He was honest. He said most CVT only hit 150k miles on them if theyre paired with underpowered engines (less than 100 hp) and a light car weight (no more than 2400lbs). And you have to drive them slow! No punching it, just rolling it. Change that cvt fluid every 30k miles is critical too with OEM oil. You adhere to these variables and the transmission has a good chance of lasting 10 or more years.
kylemas2005 .... you’re exactly right, CVT’s work better in under powered hybrid vehicles, very poorly in anything else. They are still junk.
I want the manual trans back! It keeps drivers in better tune with the car and the road.
@@Toguro-oy3ld My Mitsubishi Mirage isnt a hybrid but a 1.2L 3cylinder with 74 hp. I actually get better mileage than many hybrids. Even the little Nissan Versa is too heavy at +600 more lbs and too much hp (over 100 hp I believe) to keep these little Jatco CVT7 from burning out. Ive talked to a number of transmission specialist and they all say the same thing. "Mitsu CVT programing is much more reliable than Nissan. Keep your fluids correct, dont dog the CVT out and there is no reason a Mitsu designed CVT cant hit over a 150k miles. The fucked up thing is Nissan owns a big share of Mitsubishi. One would think their designers and engineer from both firms would cross evaluate why one is working and one is plagued with problems? Still though, give it another 5 years and the CVT issues will be engineered out. This type of transmission is here to stay.
So how about cvt on 2016 lancer ex 2.0c?is that good also?invect 3
Still, love the old manual trans.
The problem is there are very few of them. Standard transmission are automatic and cvt, sadly
I am lost after the 2nd bolt teardown. Amazing mechanical engineering. Thnx !
Isnt this the CVT that Scotty Kilmer demolishes every other show?
Scotty hates Jatco, loves Toyota.
Yeah pretty much
Yes. It's the demon inside those *e n d l e s s m o n e y p i t s*
I was thinking the same thing. Dave in Phoenix Arizona USA
Since this is being overhauled, I’d say we know why he says it
I love how western do gearbox overhaul, they do it with passion and honest. Where in my country, often time customer were fooled and cheated
This mechanic knows his stuff, pure muscle-memory right there. I'll be going back to a manual when the economy picks up. Sadly, I had to buy CVT trash recently. Getting hard to find manuals as so many drivers want to steer lounge chairs & not drive a car. Didn't want to go into debt buying a new car, so I bought 2nd hand with cash due to bad economy.
When I watch videos like this, I never want to buy another car...ever!
overpriced overcomplicated crap.
Thanks for posting I did not know about CVT when I bought my new 2019 nissan Quashqai. But I learn a lot since then it just Unbelievable, At first I felt it was like a ticking time bomb. I could not understand why would Nissan install these CVT in there cars When they fall there so much damage to the CVT that it would cost more to repair it then replace it. And it all to do with the massive amount of heat these CVT transmission generate. causing an abrasive carbon build up. in the CVT fluid. I read that before the first nissan Jatco CVT went into production nissan tested them for five years, by driving them around the clock 24 hours a day, in city traffic, up and up and down the steepest hills they could find. After the five years were up, they found there were no problems what so ever. with the CVTs. But the thing is ever few months the cars CVT were taken out taken of the teat cat pull apart and examined. They found almost no wear and tear. But the thing is that ever time they examined the CVT they also change the CVT fluid. So they did not see the carbon build up in the CVT fluid. And the damage that it was doing. But they know now that the problem with these CVT is the small amount of CVT fluid and the heat from the contact points on the cones and steels belt that burns the CVT fluid this creates a build up of carbon in the the CVT fluid. that The Carbon in the CVT fluid It is a mild abrasive and if it not removed will effects ever thing in the CVT including a small return valve that has been shown is prone to failure. So the main cause of failure in these CVT are cause by a build up of carbon in the the CVT fluid. It been found now that just by changing CVT fluid regularly as some one on here once said Around about every 30-40,000 miles. the CVT should out last the life of the car, that it was installed in .It not an hi-tect operation to change it you can do it you self easy. but it much mach the same amount of CVT fluid that came out of it.
I was a mechanic for 18 years between '82 and 2000. Great video, thanks. These CVT's are well after my time, and I find the concept horrifying.
In my day, we had the "Hondamatics". And I suspect one thing is shared between those and these new CVTs - the driver, no matter how much you try to educate them, will never adapt to the altered driving experience.
Something in the power valve assembly broke on my automatic 95 del sol recently. It ran beautifully for 226,000 miles so I can't complain much (the car was ";rebuilt" after being bought at an auction as a totaled car). You can say I've been a Honda fan for a few decades now :)
That transmission is the reason why my kid had to go to a Jr college.
They need to be recalled😔!
Nissan needs to buy back these garbage cars, or fix them for free until, 150,000 seems fair.
looks like a WHEN and not IF it fails situation by design. Those huge magnets are likely huge for a reason.
Every mechanical device fails at some point
@Shawn Huffman so pretty much every car
Hell, I can tear that thing apart too putting it all back together is a different story 🤯
Thanks for the effort on this video, glad I found it. I deal with these transmissions so much but never take them apart more than replacing the pan filter. Anything not under warranty gets a junkyard trans, which always seem to work out. The metal on the magnets and on the pan, and the dark yellow color of the fluid is consistent with 80k+ with never having any fluid/filter service.
At training, I took one of these apart like this and put it back together once. A big point they made was that if this belt was ever allowed to slip at all, it would would need a belt/pulleys/bearings because it would soon lead to the damage shown here.
I've done a few transmission videos myself, and it's tough to make it turn out to be an interesting video. Thanks for doing a nice job.
If you maintain fluid changes every 30k with OEM Mitsubishi Mirage tranny fluid can one potentially get 150k miles out of the new CVT7?
Happy that I still drive since new a 2009 Mazda 3 with 209,000 miles
Finally i found this. I have a Renault fluence (Korean made) 2012. Privilege 2.0 liter engine mr20 Nissan engine with the same cvt transmission. I have changed transmission oil 2 times since new, and the hardest thing is to find the paper filter replacement part inside the oil cooler. (Nissan part number 31726-1xf00) Renault dealer thought it was a bearing , when i asked for it in the parts catalogue. Great vid and very helpful. Thank's for it.

@@robotech1990 THANK YOU!
Jatco OR Nissan has been making transmissions systems since 1970. So, it is unreasonable to be said that CVT is the worst transmission system. I do believe that the CVT needs regular oil change as recommended by the manufacturer. The same case for DSG by VW. Moreover, people still think that transmissions systems do not need changing oil and oil filters.
Now I got the answers about CVT.. I love mechanical engineering!
The good old days of 3 speed autos and 3 speed manuals . When the colum shift manuals wore out i would pay $35 for a hurst floor shift to replace .
The manual transmissions are simple, efficient, reliable, with low cost of maintenance. Conclusion? People here in US buy automatics, to the point where the OEMs stopped oferring manual transmissions on most models.
@@bkucinschi Manuals are exasperating on city traffic and hellish on steep streets. That's why sensible people buy autos. The price to pay is higher costs if and when they fail. Manuals are bound to disappear in the future, however, as well as traditional autos, CVTs, DCTs, etc. Electric motors don't need gearboxes except for a simple reduction gearset. But I'm sure most garages wouldn't be able to fix any of them, as it is nowadays with most components already. Swapping shops I call them.
@@Gavichap : I lived in US for 20 years now but I am originally from Europe, where (at least at the time) the grand majority of cars had manual transmissions. Once you get used to that, driving in hilly terrain was no big deal. The biggest deal was to change the clutch. Last year I replaced the clutch myself to my old trusty 2005 Toyota Tacoma, took me one weekend but I had a great feeling of accomplishment. If a manual transmissions really breaks down, you can get one pretty cheap from a junkyard. You can get an automatic also, but it's much more difficult to change and adjust, and a lot of time the junkyard autos are shot too. My truck it's 200,000 miles now, and its 5-speed manual works perfectly.
Yes, people buy vehicles with automatic transmission... that's fine, they will have to buy them more often... keep the auto industry in business. Electrics are coming, but they will take a while to generalize, the power infrastructure is not there yet.
@@bkucinschi Many people including me cannot stand manuals in city traffic and on steep streets at standing starts, that's the ratio of buying an auto. It's just tiresome (and distracting) to have to costantly drive with one hand on the wheel and the other on the stick. That's one reason why over here pedestrians are run over on the zebra crossings at maddening rates (the latest just yesterday, dead): they drive in 4th as long as they can. Auto gearboxes don't come from Mars and they can be fixed by dedicated specialists, like engines (modern ones are as complicated as you can think of). Pity that most of the times mechanics are as hopeless and lazy as 5th grade brats. I fixed the 'automator' on my jurassic Fiesta myself with info I found on the internet with a DIY tool as simple as a pencil. And I know very little about mechanics.
@@Gavichap : Automatics are certainly simpler to drive, and very convenient in congested areas. My point was that all those advantages come at a cost. Sure, there are handy guys who are able to maintain and repair an automatic transmission, but most people can't so they finish up with a significant financial burden. In USA a failed transmission (out of warranty) means, most of the time, that the older vehicle is junked. So, spit the money or get in debt for a new one. For the traffic conditions in my area a manual transmission is no problem. I'm not a rich guy, so for me a manual vehicle equals financial comfort.
jatco CVT = CRAP. Now you guys may tell me why toyota has no issue with their CVT. Answer Jatco company did not build them. That's it
Is it Aisin?
Yes Toyota cvt is built by Aisin. They seem to have a way better track record than the Jatco units.
Well the reason im here is because i have a 2013 toyota axio with cvt transmission failure in my shop. no forward drive
@@shaqwalcott1326 I just think CVTs are unreliable in general. I wouldn't touch a car with one personally.
Blue Moon the main issue with CVTs failing is because companies keep putting them into heavy and medium - high torque cars. Something these transmissions definitely cannot handle.
No need to apologize for your YT skills. Good video which confirms my beliefe I will never buy a CVT unless sometihng REALLY convinces me otherwise.
Mr. Nunna that’s where they are leading us though. Eventually it’ll be damed hard to find a standard or traditional automatic. They will improve over time, but for now I agree with you. Avoid the headache.
People used to say the same exact thing about automatics lol.
Redslayer86 and they were right. Given time they will be as reliable, but not yet. IMO.
Americans want to drive and roll joints and text or chat-too tough to do that in a manual!
I didn't know Mel Gibson did transmissions.
Rite?
Lmao

Do not buy a car with a JATCO transmission !!!!!!
Today, JATCO has become one of the biggest supplier of CVT,
and products from nearly every auto maker have used Jatco transmissions,
with the notable exceptions of Honda Motor Company, who makes their own
transmissions, and Toyota Motor Company, who has always used transmissions
made by Aisin, a subsidiary of Toyota.
Subaru makes their own CVT transmissions.
@@steverobertson9655 Yep....and they don't have that goofy belt design. They use a chain design. Significantly better.

Fluid, fluid, fluid, fluid, fluid...………….. Did I mention changing the fluid? Also, heat is the enemy of any automatic trans; even more so with a CVT. A cooler is not a bad idea, either.
A CVT is not a automatic trans it's the same as a snowmobile or a motorcycle
I always tell people to change the fluid and install a trans cooler but I am usually told that they have a "warranty", or that the fluid is good for "life". It's not expensive to do a drain and fill every so often on a vehicle. I was also told that car company's would put something in a car that was worse than the previous years. Some people listen, some don't.
I was told by Nissan that a 6 year or 84,000km fluid change is mandatory for these transaxles - otherwise they tear themselves up not too shortly after.
Still not a fan of these transmissions - they are real smooth but Nissan programmed in "shifts" which really negates that feeling in the newer cars.
If you drive normal with light accelleration it still gives the smooth accel without the shifts. I've gone from 25-60 without the RPM changing more than 50
the transmission that ruined Nissan
It has not nissan will fix the car but I must say I have had a good run with my 07 Altima it has 288.000 miles everything I owned. Before was a lemon! I really want a Maxima 09 man take a chance don't listen to people!

@@imlamar2011 just leased a new maxima for my wife. Great car. Best part is they throw in all maintance for life of lease, no worries. Get a kick when some say I got a million miles on this car or that car. When you get older you deserve a new car with no worries....
Most Nissan owners are perfectly happy with their cars, but obviously the people screwed over by their transmission make a bigger stink than "yeah, it's still running" 😛 79k miles on my 2016 Versa Note and it continues to run well, I enjoy driving this little car.
Powertrain warranty is 5 uears 60,000 on nissans now. Almost all the horror stories put them going out between 20 and 40,000, so buy one cause everyone else whines when they only get 180,000 miles which is on par with alot of regular auromatics. Regular fluid changes and it will probably last longer than youll wantto keep the car anyway
"Okay, now this is really delicate..."
* _crash!_ *
I’ve heard those Nissan CVT’s can cost 6K to rebuild. If it goes south it’ll basically total the car
yr work is awesome on that cvt!! Unbelievable the skill u have. "salute!!
Is this what happens when you don't change the transmission fluid on a regular basis and/or change it too late and the transmission breaks later on?
* I own a 2014 Mitsubishi Lancer ES with a CVT, and I'm potentially facing this problem sooner or later...
I saw one where the shaft had worn out where the banding sheave bearing had split in half and the sheave jambed up blowing the metal bands all to hell. The shaft material is much too soft. They only use 3 grooves for those bearings. The transmission had 180k on it. The belts or bands didnt fail until the pully or sheave rotated and locked up. All hell broke loose then.
Good video Matt! Longer video`s please i find it very interesting!

so the new CVT transmissions are run on bicycle chains?
That chain runs the pump. The metal belt runs the CVT but it's about as bad tbh imo.
Nice video I'm taking my first one apart now thank you
There's so much to be impressed by but the thing that impresses me most is not once did you call something a doohicky, whatchamacallit or thingy.
That's cause those newfangled cvts use gizmos and doodads...
What causes these failures? I have a 2013 sentra with a jatco cvt that judders on the first acceleration starting cold and I'm afraid the pulleys are all scratched up like this one is. Dealer won't help unless it throws a code, and by the time it does it's already too late anyway
They actually have a nice tool at Mitsubishi for separating that case so you don't have to pry and gouge shit.
I have the same transmission in my 2014 Mitsubishi Rvr (Outlander sport) and the car drives fine but every now and again at hwy speeds it will start to whine and the car tells me to slow down and that the transmission is overheating. Should I add a oil cooler or is the transmission slowly dieing? Thoughts?
If its a jatco cvt transmission then just say goodbye to a few thousand dollars in repairs. Nothing you do can save that transmission.
I have this transmission in a 2008 Lancer. There is a clicking noise that sounds like a bad inner CV axle but I've been told that the noise is coming from the transmission. The axle boots have been leaking and the noise is only heard when coasting with the engine running. No axle noises with the wheels cut and no noise coasting while the engine is off. I've been driving it this way for quite some time and the transmission isn't slipping. I just did the second transmission fluid change (80,000 and 140,000) and the mechanic showed me the pan on request. The fluid was of good color and there were no metal shavings on the magnets. What could this noise be? Should I worry about it or just keep driving it that way? Could a bad inner CV axle be the culprit?
You should use magnet trays to keep your bolts together.
love your video bro.
guys seen many transmech.
kennedy do knows what he is doing.
i just hope the price is gd.
cheers.
that fluid was really dark...was probably never changed
Many of these don't have a dipstick and are sold as lifetime fluid.
You can change it.. but most people don't know about cars.. and just do what the manufacturer tells them.
Yeah I have a 2019 Versa that has a CVT and the trans was shuddering like crazy until I changed the fluid. Now it operates smooth as butter!!!!!
Think you've done that a few times before. Great video.
I have a 2011 cube it has a loud whine/clunk noise coming from the transmission, i wonder if this is my problem
Yepp... I was hearing a loud whine not too long before the trans gave up at 91k
cant they make those push belts out of something like the pump style chain ? it seems the push belt is the weak point
I knew about the Jatco reputation. Still, I bought a car with Jatco CVT. Now, it has 80.000 km, no problems at all, 1 regular transmission fluid change and hoping for the best. I love the tranny up to now (until it breaks). Mitsubishi is a bit smarter than Nissan using these CVT transmissions. I have a Mitsu, so that gives hope.
Mine is around 155k miled on 2011 lancer. Still good,until now i dont know there is oil filter and cooler cvt,i might service/replace it later..i usually change fluid around 50k km interval and using the oem mistubishi cvt j4 fluid

Hi, I was wondering about the part where the audio cut out regarding the oil pump. Is it true that the main failure point of these jatco Cvts is the oil pump? If I simply changed the oil pump and left everything else as is (making sure nothing else was damaged of course), would that be enough? I’m asking cause even doing a full rebuild myself is still $1000 with all the parts and tools involved.
My CVT transmission on my Mitsubishi Outlander 2008 doesn’t shift gears automatically while on drive (D)mode it remains on 1st gear. When I use manual mode (+/-) gears shifts smoothly. Do you have an idea how to solve this issue ?

cvt is inherently unreliable ..
Is this the same cvt they use on the eclipse cross? Thanks in advance
I own two vehicles both with CVT transmissions. Of the two I trust the Italian one more than the German one. I should probably move to a house near your shop.
Why is it all scratched up? No proper lubrication due to not changing the cvt fluid? Just curious what the cause was?
Common weak point on these is the flow control valve in the pump, when they wear the pump loses pressure and the pulleys can't stay as tight causing the belt to slip. This will result in marked up pulleys. The pulleys are super hard though and can probably be cleaned up like new.
No CVT for me. That crap belongs in golf carts and mopeds.
You forgot snowmobiles
its faster than any manual or duel clutch automatics so... yeah. They just need to add strength to the parts.
I have a 2015 Altima feels like it’s slipping under light acceleration. Do these throw engine lights when they go bad? Is it possible to just change the fluid and it’s good or am I toast already?
I just bought a 2019 nissan NV 1500 van for camping. Did I get the terrible Jatco tranny. ? Should I get rid of it before it goes out ? Help please. !
No. Only the little nv200 has a jatco cvt. Nv1500 comes with either a 6 or 7 speed automatic trans.
Do you know how many miles it had before it wore out like that
Got a question the 011E I can get parts for no problem but the 015E not so much. Have you had any problems with this ?
Nissan is moving away from Jatco CVT. Are they that bad?
Curiosity only, about how much would it cost to remove, rebuild and reinstall that thing? Thank you in advance for an answer and for an interesting video.
Robin, They really vary by what vehicle they are in and what has failed on them. In looking at our most recent few JF011E's that we have had to re-build, they have varied from about $2500.00 to $4000.00. The condition of the pulley sheaves and shafts, differential and transfer gear (and any bad electronics that may have failed) can really vary the price.Thanks,Matt Johnson

That little bit of wear was the problem??
I have a 2011 Mitsubishi Lancer, and my cvt has a loud whine and I get a lot of over heating issues after driving on the hw for more than an hour, the car has 130,000 miles, changed the trans oil 30k miles ago the over heating stopped for a while, the car also feels like a “slingshot “ I’ll give a little gas than the car pauses than jumps to speed, what could be the solutions for that ?
Did you ever find the solution to that issue
Very interesting video. Have a question for you sir. My cvt trans is leaking from where the torque converter sits but not sure where it’s leaking from. Is there a seal that is easily accessible to replace or would it be the torque converter that’s leaking? I’m fairly new to looking at cvt trans I’ve only broken down regular 5/6 speed manual trans so far. But I really appreciate this video.
Matt, I have an 08 Lancer that makes a whining sound only when moving. It sounds like a loud electric motor. When people ask; I tell them it's the "Electronic Turbo". Road sound usually blocks it out over 35mph. I bought the car months ago (knowing about the sound) and immediately drained and added new CVT fluid, but no change. I have put many miles on since and have had no problems. I lifted the car and let the wheels spin while running; I am fairly confident the sound is coming from the CVT. What do you think is causing it?
Ankly,It sounds to me like a bearing. It would be a good idea to drive the car on a free wheel hoist to make sure the noise is actually coming from the transmission. Unfortunately, none of the variator or transfer gear bearings can be serviced without removing and disassembling the unit. I would also expect to see a heavy metal content on the magnet in the pan if this is a bearing issue.Thanks,Matt
Sounds like the CVT is beginning to fail.
Change the cartridge filter and o-rings in your CVT cooler housing, which is below your battery tray. The battery tray can be removed to access it. Then change your CVT pan filter and gasket as well. Use Eneos or OEM Mitsubishi CVT fluid and original parts only.
I did this to my Lancer and no whines. Change these filters every 60-90k miles. I would go for the minimum.
HI...i have same transmission and it has whining noise from the transmissions. While driving I can hear the that and If I drive car on down hill with out starting the engine that time also noise coming. What could be the problem... Can you give me some idea... Thanks.
Rajitha,
Whining on the Jatco CVT's is usually one of 3 things: Low CVT fluid level, a sticking pump flow control valve or a pulley bearing starting to fail.
Thanks,
Matt
Where can I find a torque converter? For this transmission
I'd never buy a vehicle that has a CVT Transmission. They never seem to last very long. My friend is on his 3rd CVT transmission in his, I think it's a 2015 Nissan Sentra? That car is so weak with that transmission, the engine nearly red lines on hills that my. civic will cruise up at 2000 rpms. On a flat road I guess a CVT would be ok? There's a lot of hills in my state. I just think CVT is a poor choice for an area with a lot of hills. His car is on its 3rd transmission before it even hit 100k miles. Those things are a major piece of crap,not to mention that they're really expensive to fix. I'd never buy one.
You tell your friend to chill on the burnouts
just don't buy cvt unit cars.. either manual or torque converter auto transmission

The mileage on any of these machines doesn't matter. The way YOU drive does! CVT's are "economy" transmissions, it's not a Ferrari so don't drive it like one. If your MPG is NOT 28 or greater, you're doing something wrong. Like firearms, it all depends on you. It is NEVER the machines fault, it's the operator.
As you say mileage doesn`t matter if all it does is city work and short running.
It says it's the operator's fault. If you're consistently avoiding highways then it's still not the machines fault. It's you! It does say that right? Or am I blind?
After I purchased our 2014 Subaru Forester, I only learned from You Tube vids in 2017 that our CVT IS A JATCO. We have 75K on it, but I started doing drain n fills at 60K because I know oil does not last forever. Subaru states not to break thexseal on them as "they are gaurenteed for LIFE". Whose life anyway? Warranty, thats it.
So, between many Subaru blogs, my independant mechanic, I am currently flying in the face of what Subaru recommends.
Same with engine oil. Maintenance manual states 7500 miles, i change mine at 5000 miles.
Differential was recommened to change at 60K, my mechanic said 50K is about as long as they would go.
So I am coming up.on my 3rd drain in fill. I am concerned as the color at the first drain was beige, the second was more amber. Any thoughts?
@@robertweber3140 I don't think that the Subaru CVT is made by JATCO. According to WIKI (ok, i agree it's hard to find a legit source of information on the internet sometimes), Subaru's CVT transmissions are named Lineartronic and are made by Fuji Heavy Industries who is Subaru's parent company. Looks like the previous Subaru automatics and some of the manual transmissions were "JATCO designs adopted to Subaru specifications."
@@nucklez , thank you!
Thanks for the video, but the sheaves and belt don't seem premium enough for the load placed on them. Some CVT are worse than others, just like you should not buy a ford which has DPS6 dual-clutch.
Scotty Kilmer: Stay away from Jatco
Great video!
I have a 2010 Nissan Maxima. Would you recommend dropping the pan and replacing the filter and fluid like on a conventional auto? If yes, any tips?
TommyMacDaddy1 I recommend a drain and fill/pan drop every 30k miles or having a Nissan dealer read the deterioration rate using Consult. Although a dealer costs more, I recommend only having the dealer do the transmission service because they’re such a sensitive transmission and can typically only run on Nissan’s genuine CVT fluid which happens to be NS-2 on my 2010 Altima.
What would cause a cvt to delay engaging into the next gear when getting up to highway speeds? My rpms just start screaming and the next gear never comes until I drastically let off the accelerator
That's literally how a CVT works. There is no "next gear."
U should leave some brochures at a Nissan dealership in the showroom. Leave them in the front seats of the car on display.
We do get quite a few customer's referred by dealerships in the area, and Nissan USA has asked me to assess some of the pulley assemblies that they have coming available. However, they have not had the proper sku's that I have needed ready yet, so I can't speak to their viability.Thanks,Matt Johnson
Knowing the belt and pulleys are likely to need servicing, you'd think they'd design them with repairs in mind.
Like a snowmobile ?
is it worth rebuilding these cvt trans....and how much do you replace while in there?
also how many hours to remove/rebuild/reinstall one from the average vehicle 32hrs labour?
We repair or overhaul a lot of CVT's and build each unit independently. The prices vary widely. In-vehicle repairs can be relatively inexpensive, often under $500.00, but overhauling and upgrading the unit in most cases is a minimum of $2000.00 (with removal and replacement). They can certainly get much more expensive depending on the unit, the vehicle it is in and the extent of the damage. Variator/ sheaving, pump, transfer gear etc... damage can drive the price up quickly.
2000 isn't bad, that is inline with a traditional automatic, I know locally, we don't have any shops that will rebuild CVTs, and the independent shops won't even do R&Rs on them. Dealers will only replace them with new units to the tune of 8-10k depending on the car.
@@mrvwbug4423 lol even a dealer isn't charging 8k for a trans replacement, get real
The whole thing is the entire problem. People should get together and file a major lawsuit against CVT manufacturers and totally ban CVT from being used on automobiles.
mine 2014 Mitsubishi lancer cvt transmission only when is 221 temperature fail but under that temperatures works good what can it be??? tanks
The manual transmission has a flywheel to start the engine, what about the automatic transmission.
The same goes for automatics.
given the absolute horrible experience I had with Kennedy Transmission, I would never recommend them to anyone. Took at 1998 Accord V6 in to the Blaine location and $3600 later and 4 failed attempts later to correct the issue, sold the car with 100K on it. They rebuilt the trans at 89K...
As much as I hate to say it, AAMCO at least down where my dad lives is the best in town, they rebuilt his 99 Continental tranny back in 2004 for $2400. It was covered under the extended warranty he got from the credit union which more then paid for it's self, but he keep the car for 11 more years and never had a single issue with that transmission again. My older sister destroyed that poor car, but the tranny was still running strong all the way to the salvage yard.
Seeing the disassembly techniques and tools used, I'm not surprised.
Why the fuck would you rebuild a trans at 89k? Couldn't you tell it was fucking junk?
Mitsubishi seem to have less problems with there Jatco CVT`s than Nissan is there a reason for this ?
Chris Cook INVECS ECU and the Mitsubishi engines equipped with this transmission makes less than the maximum torque limit of this transmission, which is 220 lb.ft.
@@ricksays7133 So they fit the correct transmission for the car then ?
Chris Cook Yes, but I still think it would have been better if they used a 5 speed automatic. Mitsubishi used this transmission for fuel economy but I don’t think it matters when it gets 26 mpg on average daily driving. A manual transmission is still better imo.
We have two of these cars owned by family members going on ten years old now no problems.
Thank you for This info,my wife lancer is around 155k miles as today..great to hear that invecs ecu is good with cvt ..
Where can I get a replacement clip for the electrical connector?
how long should my 2012 mitsubishi lancer with this transmission last? i currently have 125,000 km on it
change fluid and filters every 30k
