OK 6 speed manual, 100% convince by your clever explanation. thanks for your outstanding knowledge and experience.
Excellent video despite its age. Thanks for posting. Not surprising how many companies are switching over to CVTs.
Thank you for sharing this. Informative.
Interesting to see inside this and to have it explained clearly. Thank you.
Excellent explanation of how it works, and description of all the bits, thank you! I'm very glad there are smart people who know how to fix these :-)
There is but the labor is so expensive most dealers just replace the entire transmission. It is much cheaper to do that and you don't have to worry about the remaining parts. If one part is worn out most likely the rest are on their way.
Well done Sir. Really professional explanation.
Such a depth of knowledge ! No guess work at all. Speaks volumes for the MRT business
Excellent post! I'm shopping for a 2018 outback with 6 cyl engine. I hope they are reliable transmission. Thanks for posting. Prescott AZ USA
Here in the U.S. we call them Continuously Variable Transmissions. Constantly variable sounds like a problem.
Thanks for the video. Excellent job.
I've had two experiences now with changing the CVT fluid, dropping the factory fluid & putting in Amsoil CVT fluid. 35 years now working on cars, trucks motorcycles etc and it's still hard to believe the very tangible difference in performance. These CVT transmissions really like Amsoil CVT fluid!
Nice videos. Interesting viewing the inside of this transmission.
It would be nice to see a video on the maintenance of this transmission.
awesome video! cvt trans are totally alien to me but me and the wife are getting an XV soon so I've been doing my research. nice to see all the internal bits to help understand how it works.
@Joseph001 Woah! That's sucks
Excellent review, thanks.
Secrets or not, it's neat to see the internals of an actual production unit take apart, thanks!
I dont mean to be so off topic but does anyone know a method to log back into an Instagram account??
I somehow forgot the account password. I would love any help you can offer me
@Damien Dalton instablaster =)
@Marc Kaden I really appreciate your reply. I found the site through google and Im in the hacking process atm.
I see it takes a while so I will get back to you later when my account password hopefully is recovered.
@Marc Kaden it worked and I finally got access to my account again. Im so happy!
Thanks so much you saved my account!
@Damien Dalton glad I could help :)
Love all your video very educational keep it up
I have a 2018 Subaru Legacy 3.6R with CVT. It's my second CVT Subaru. (2015 Forrester) I have had no problems with either of those cars and would recommend them to anyone. I am a car guy from a car family. Driving, for me, is one of the most enjoyable parts of life. I'm passionate about it! Get it? It's such a boring, stale, and old meme to hate on CVT transmissions. Yeah, I'd get a manual if I had a Porsche or even a Mustang GT. But seriously, this Subaru CVT transmission isn't unreliable or "gay" (comment by a moron). I drive mine really aggressively at times and the thing just takes it and asks for more. So please understand that some of us have different opinions from the haters. Finally, electric cars mate beautifully to CVT's. They'll work perfectly for that application and will only get better over time.
Not much of a testimony. Your oldest CVT is 3 years old. Get back to us in 10 years.
I bet you you never drive ou of the city. Go take the Forester on some dirt road every weekend and you will slowly hate the CVT when it start slipping
You've clearly never gone up a hill on a dirt road with either of those cars. My stick subaru does it no problem. there are literally tons of youtube videos showing the cvt can't make more than like 40 to 60ft-lbs of torque in certain circumstances
Just like using incorrect oil viscosities for the motor, the vehicle WILL take it until you accumulate mileage and duty cycles. Most cars in the States are traded between 24-48k miles, hardly enough time to pay the note. It's those owners/drivers down the line who need to be most concerned. Go to any car service department here and you will see the majority of issues and failures stem from the CVT or its components. The only thing worse than a car that won't start is a car that won't move.
LOL, you've had the car for just a few years and haven't driven far no doubt. My 2011 Liberty CVT just had a "solenoid" or something that controls the oil pressure for the torque converter (the drive phase where the gearbox/converter locks up into full CVT mode) fail so it feels like it clunks into gear when it used to smoothly convert to full CVT mode. The car has done 256000km so I'd expect things to fail but not be basically unservicable. These things are designed to not be serviced (as told to me by Subaru) so will cost $1500 - $2500+ to fix (parts are $2000 before labour, or I could get a second hand CVT to save a few dollars) as the whole thing has to come out and be pulled apart. I love how a CVT drives but whoever designed it is a dick head considering my 23 year old Ford Falcon has hardly any issues at 318000km and if it does it costs a couple hundred dollars to fix. I'm going to contact Subaru about this as their CVT's are known to have issues (Google it)
Great video and very informative.
Very well explained , thanks
Thank you! Very interesting video!
This is why I drive since new a 2009 Mazda 3 s hatchback 2.3 with 5 speed auto and 195,000 miles. I have been dumping money lately for suspension parts at all four corners and a trans module. A trans module is not a rebuild. At the end of the last 5000 mile oil change interval I got back from a 2000 mile Marathon trip in 50 hours. Car ran like a champ. Did not burn or leak a drop of synthetic oil.
Thanks for the look inside. Wouldn't have minded some video of the teardown, explanation of any special tooling and such, since it looks like I'll be pulling one soon.
I had been pretty happy with my wife's 2012 Outback with the CVT, until recently when the car started hesitating coming into a stop, then started stalling. Apparently there were some defective torque converters that aren't unlocking as the vehicle comes to a stop and stalls the engine. Last thing I was expecting from a Subaru was a transmission failure at only 75,000 miles, which, of course, is out of warranty. Worse, when we bought the car and I questioned the dealer about the transmission dipstick, he said there was none and went on to say there was no need to ever check or change the transmission fluid. Now, I hear the manuals are calling for changing it every 25K miles or so. Not happy.
If you've got a torque converter issue then that's comparable to having a clutch issue in a manual gearbox, and likewise would've had the same torque converter issue in a standard automatic gearbox.. No reason to throw any negativity towards the CVT at this point.
Thank you for share you knowledge 👍🏽
These Transmissions have been around for years on large Industrial Punch Presses. I've got a 2016 Forester and love it, though I am a very gentle driver. I really like not shifting. Guessing that this transmission is not for Trailer pulling or other rough use.
With a cooler and staying on the fluid change intervals, you could do mild to moderate towing, but nothing extreme. Look at the Ascent.
I've been an industrial mechanic worked on hundreds of these which has common Reeves drives and us drives what is basically the same thing cvts a little more complex
Commonly used before the innovation of variable frequency drives to control motor speed
Great video! What years are these transmissions used? Thanks.
great video thanks
Great info thanks
Informative video. I was considering buying a Subaru Crosstrek, I made up my mind before watching this video that it is not a wise decision to purchase one. Why can't these manufacturers have a regular automatic transmission as an option they're shooting themselves in the foot!
They can theoretically get better MPG with a CVT, but that is before the fake shifts are added. (a $7K trans replacement will buy a lot of gas)
thanks brett good info . Just one question why is there a lemon on the shelf above your assembly bench ?
restolad lemon implies that every car w/ cvt is a "lemon car"??? 😆✌
Hi in the video you mention very special needs to keep it running well. What are they? Ie how to maintain/use it to last as long as possible? I don't suppose manual mode vs non manual mode makes a difference? Drain oil and change external filter? How often? Thank you. And how often to change the diff oil?
From what i hear, consistently changing the fluid will prolong the life of the transmission. Also because the transmission has a lot of intricate parts, a "power flush" is typically not recommended.
Good work air
@MRT Performance , any thoughts on a 4EAT swap?
Thank you very much for information. So, This subaru lineartronic belt is a pull-belt, actually pull-chain. It is not a push-belt like in toyota multidrive isn't it???
While no secret was revealed, other than full disassembly required for filter change, your Oz accent gave the video a "Richard Attenborough" like effect which was enjoyable. Great video. Thank you.
If it helps anyone, I have the 2010 liberty with CVT transmission and a few months ago around 120k mark the CVT fluid was discoloured and needed a full flush. I used aftermarket fluid because the genuine subaru stuff is crazy expensive.. hopefully that helps people wondering what type of average life span you get out of the oil. The car was never uses for towing and hardly ever driven fast, plus there were no metal particles in the fluid. I think I'm gonna change it every 100k myself to be safe.
Can you please give me an update how it's going without the OEM fluid? I'm looking at the penrite chain CVT fluid
My Subaru Levorg has a scheduled CVT fluid check/change at 120,000 kms.
my 2010 subaru outback gearbox was whining now the sound has gotten worse with grinding noises. thinking its a bearing.
Great video!
One question
How would you test for Glycol (Antifreeze) presence in CVT Fluid or ATF Fluid).
In case of transmission cooler leakeage
Appreciate your Assistance.
Thank you
Good video thanks for making and posting. I have a Subaru xv and have been told that it's a sealed unit and does not need a fluid change, I don't believe that. Do you recommend fluid changes in the Subaru cvt and if so at what km intervals?
You need to change oil fluid for every transmission at 80 km at most or at 70km for safety don't believe any one said tbe oil in transmission is lifetime
@@MyLife2020 45.000 km
Nice video. Have a 13 Outback setting a P0841, secondary pressure low. If it is an actual low pressure, where would you look?
Great video, can you compare 2 diferent cvt from subaru the hi torque and the other une to see the diferent.please
I gave a couple of my auto enthusiast friends a ride in my 2016 Legacy 3.6R. They both thought it was a stepped automatic transmission. CVTs have gotten a lot better from a performance perspective. Reliability wise...time will tell.
Any update on your 3.6 please... I've got similar (2017) with 165k kms about to do the CVT fluid as a precaution... any issues, and do ya drive it enthusiastically?
@@peterlattimore6013 Yeah I'm still driving it with spirit lol. I'm at 74k miles (119km). Still no transmission issues and only really minor stuff generally! Had my CVT fluid drained and filled around 50k miles
In 2017 I was interested in a new 2017 Forester and when I found out that the towing capacity was 1500 pounds and that was because of the CVT my interest in the Forester or any car with a CVT ended.
I do hear that Bill, just now, we pulled out of a deal for the 2016 Outback for that--and for general reliability issues.
For more torque you need a thicker belt and more pressure on the pulleys, that's logic. But how many Km/Miles did that filter service?
I understand that overheating can cause some serious problems for a cvt. Does it make sense to install extra cooling even on a everyday driver?
1:55 mark. I was waiting for: "That's not a knife. XD Thaaaat's a knife."
I am on the market for a mid size SUV. Subaru and HR-V are all CVT and I am a bit nervous about a trans that needs to have clutches and oil in peak condition to keep the steel belt from slipping.
You also said that about 400Nm is the limit before the torque overwhelms the internal traction and the thing stops working as it should.
Does this mean that:
a. most 400Nm+ turbo diesels will be CVT free?
b. Towing may be a problem, and
c. heavy cars/SUVs will not have CVTs?
What's the "rule of thumb" about CVT and size/weight of vehicles where it is not wise to contemplate the CVT?
Ned
I like my 2001 Nissan Primera P12 CVT, it has 110000 Km on the clock, it still goes like new, Being aware that a CVT transmission is in your vehicle and how they work especially knowing what not to do to them like, Putting the gearbox in the opposite gear that the vehicle is moving and towing heavy loads. The gearbox will last as long as a normal automatic. Just remember DON"T MISS A SERVICE, keep the oil clean and she will last a lot longer!
The worst part of that CVT is that oil changing is essentially futile. Virtually none make it past 150,000 miles, and most die between 80 and 120,000 miles. The Nissan drive belt and most all early Jatco trannies have a dependable failure time because the design of the belt elements is flawed.
gelul ik rij in een ecvt van '97 met meer dan 3 ton op de teller
Have a Subaru Forester 2.0 D, new since 66. Best car we have ever owned (I'm 70 yrs old and have had all the main competitor brands from new at some point). My only criticism of the Forester gearbox is that the manual electronic change (paddles) is totally unnecessary and just adds cost.
I know Subaru is recommending service only if you are towing or driving under extreme conditions, but maybe the cvt fluid should just automatically be changed every 30k miles.
Preventative maintenance
That will actually cause more leaks and discount mechanic misadventures than it would do to prevent CVT failure. Unfortunately the alternative puts it out of warranty.
Just getting over my first serious hatch...sadly she had already been out of warranty right about that time where we found out she had CVT (disorder).
Fortunately I was able to blame it on the electrical component recall causing uneven resistance at the breaks, dif and CVT like I did. Dealer was happy to fix it on Subaru's dime. Now she's not just running tight...Dare I say she might be tighter than die hard catholic girl's father hopes for when even though she's off to band camp.
Knew she wouldn't stay like that forever so I quit while I was ahead. Gave up on my dream to make it as a pro skater with his sold the rights to that brand of personal vaporizers that's always getting suit...Now I spend my days writing elaborate bullshit in the comments section under youtube videos.
It ain't much but it's enough to take care of the Porsche and I and still come out ahead on quality time and repair costs.
(Even paying 700 dollars for her expensive taste in lube I'm now debt free and 500,000 dollars ahead of last year not having to worry about CVT repairs and all the court charges associated with blowing sick clouds at the 5.0 to block them out for being haters.
After growing the fuck up and refining my taste I've learned a there 3 key considerations when deciding whether to cut your losses .
1. CVTs are have been around for a while but just haven't had the same number or R&D hours thrown at them as a trusty stick or most newer geared autos.
Despite the reduction in complexity on paper the R&D needs to catch up for most of their theoretical advantages to be genuinely worth the drawbacks.
2. Keep in mind that Subaru decided to trust Nissan to design and supply their CVT. (Toyota was outbid but supposedly their CVT is bulletproof...but still a CVT.)
3. This issue affects about 5% of units. To put this in perspective of every 25 guys and gals who make the decision bring these cars into your life 1 will be emotionally abusive, gaslighting them into becoming hollow shells of their once happy selves - Know what to look out for and put your foot down early...If that fails hiring a professional is likely covered by the powertrain warranty if you don't ignore the signs.
Be careful with the latter of the 3 however...she's still like that crazy red headed catholic girl and just leave you like the social studies Prof she's calling daddy.
Eventually you'll probably catch on to her antics but after after putting up with her drama but realize a moment of clarity too little too late because she spent all your money on the "body work" with your only solution left being to insert your 2nd favorite mötley crüe album into the single CD slot
...Couldn't use kickstart the heart because it's on your android that is constantly ignored by the ice cold temperament of the 2015 subaru starlink headunit.
Settling for "home sweet home" You realize you've made just another poor decision to add to the snowball of mediocrity that have ultimately become you and proceed to floor it 0-59mph in a blazing 15 seconds balling your eyes out as you run it off a cliff before you can even get a taste of 60.
Not that you'll have had any business expecting better for yourself given your low expectations coupled with that acquired deranged taste of yours to punish and blame yourself.
This time will come well before it's time to replace the CVT so don't worry about prolonging it's life. You're only feeding your disease.
Instead...
KILL IT WITH FIRE!
SELL IT TO A FLATULANT 300LB UBER DRIVER
ANYTHING BEFORE IT CONSUMES YOU!
jake lami have you seen the transformation of the fluid after 50k miles? It’s pretty degraded. All fluid gets hot, breaks down, and gets contaminated. The manual itself states several factors like weather, towing, where it recommends the fluid to be changed.
Also, pretty sure Subaru made their own cvt, not jatco.
@@MrFloydroy Maybe I'm wrong. Nissan owns the big share in Jatco for sure. Maybe it was Shitsubishi paying the dumb kid to do their homework.
@@MrFloydroy You are correct, Subaru has been making their own CVTs for over a decade. They also recommend fluid changes at 30km & 60km in Japan & Canada. It's only the US manual that states 100k miles (15k if towing), most likely to lower the cost to own for marketing purposes.
I am not a mechanic but I recommend swapping the fluid out more frequently than the US owners manual.
While I do prefer a standard transmission, my Impreza with it's cvt is actually pretty enjoyable.
Stomping on it, it's pretty quick to react, although definitely slower than a standard. I can never complain about 43mpg on the highways here, and while it does whne or whirr under load, it's not very loud about it.
It's fun, but I am afraid of the day it gets worn out and has to be replaced, as that transmission is also 1/3 the price of the whole car.
I love my fb20 Impreza w cvt as well. Not fast at all but great on gas and excellent in and weather
So does the CVT use the same kind of torque converter with a hydraulic fluid as a regular automatic transmission?
Please explain what stops the belts from slipping inside the pulleys.
My 2015 XV was just diagnosed with this issue. My question is what kinds of issues could arise if that bearing was not replaced in a timely manner or at all. The dealership here is quoting $3,500 for a used and $8k + for new. We put a lot of miles on the car and didn't realize this was going to be that expensive of a repair. Thank you for taking the time and putting together these videos.
No warranty? :(
May I ask a typical rebuild cost for the smaller cvt transmission? I have a relative whose forrester trans just failed 6 months out of warranty and of course Subaru wont help.
what are the differences between the the standard and wrx cvt that you say is bigger? i have been told they are called high torque models. and are available in the wrx,3.6 legacy and the forester turbo models are these all the same models?
Como se revisa el nivel de fluido en la caja de transmisión automática del Subaru Impreza Premium 2.0 Lt. 2012.
I bet the auto start/stop function is what killed the bearing. Horrible technology that doesn't save much fuel but kills engines and transmissions.
Walter Black
Not to mention killing starters and batteries extra quick.
Hmmm.... Save a few liters of fuel or burn through lots of batteries and starters in record time? You drive a hard bargain...
I have not see these features cause these issues. The auto start/stop is only an issue if stop is prolong for hours. This could cause problems with starters if they are not built robustly though. Batteries can suffer if the engine can not respond quickly to the start up though. However, AC, even with alternators, have caused more damage as well as the older style halogen headlights. It's a common reason for Subaru's to have failed alternators and batteries, because people drive with all of their accessories and lights on. (Lost 3 alternators and 2 batteries and learned... way to late, even killed the wiring connected to the alternator, that sucked. This was on an older car and contamination was a factor.) In fact a AC takes around 20 amps and a starter between 20-30 amps. This can cause stress on the battery either way. Thing is, for a well maintained car, it take less than a revolution of the engine to restart the car. This means it takes very little of the car or the starter. I would mimic the start stop method at lights with my subie to save gas, the only thing that wore after 21 years was the lock cylinder. Which was a cheap and easy replacement.
Walter Black Subaru does not have start stop.
Barclay Brett says it himself in this video, they do.
can confirm 2018 WRX does not stop start, I know manual impreza's and CVT impreza's with smaller CVT's use it to get fuel economy.
What causes the fluid whine from the front of the first gen CVT like in a 2012 Subaru Legacy USDM?
I have a 2012 Impreza Sport Limited with the 2.0 and CVT, bought it from a Subie dealer at 106k with a 30k Extended Service Agreement... Subaru replaced the trans valve body last year for free at 115k, and after failing an oil consumption test at 121k 10 months ago Subaru replaced my short block for free, then two months ago at 127k my input shaft bearing went out and Subaru replaced my entire trans for a $200 deductible. Now I’m about to replace a gasket on the rear differential myself that is leaking...
Maybe it's time to sell it
Harbinger lol
so whats your take on the F1 motorsports Cvt torque converter upgrade?
My 07 Nissan Murano just hit 123k miles and I have a complete transfer case failure along with extreme cvt failure due to flawed design. I’m extremely wary of any car now with a CVT. Gonna try and get trade in value HA
Good reason to lease Subi's. They do have a high residual so lease payments are pretty good compared to other brands. Unfortunately most mfgs are going to CVT's as they help with CAFE requirements. Yes you can partly blame the govt for the CVT craze.
So did the owner of the car tune it so it went over 400 NM of torque and that caused the damage? Or what damaged damaged it?
Don't think it was tuned. Just not a reliable design.
Nice 👌
How many fun tickets is it roughly to replace the metal belt when it shits the bed?
Would you advise a manual gearbox if doing a lot of heaving towing at full weight? Also, quite a lot of off road use as well. Many thanks. Great video, thoroughly enjoyed watching.
CVT's aren't designed to tolerate pulling heavy loads. NEVER go beyond the recommended tow rate!
If you plan on pulling things like large campers and boats, CVT's aren't for you.
Many thanks, I tow two large trailers with a gross weight approaching 2 tonnes so it's at full weight much of the time. Also, quite a lot of time in fields as well. I think the manual is going to be the way forward. I'm in England and we don't have much snow, but the relentless wet winters do take a toll when towing through mud etc. Many thanks.
yes,manual trans
@@simonbroddle754 If I remember correctly, the tow rates in the UK for Subaru are nearly double of the US which is around the 2k or 3klbs range. Not sure WHY exactly, might be a efficiency thing and the transmissions are geared differently. But something to consider and always just follow your user manual.
Also, the rating are the SAFE level and probably at least half of their true capacity since the amount of force is variable while driving, I wouldn't test it though since tongue weight at least is something you do NOT want to over do, unless you want your front wheel to loose traction from lift. But depending on distance, you can get away with pushing it a bit. Same can be said for manuals btw.
@@darksd3626 Hi Darks D, Thank you for your reply. I do tow up to 20,000 miles/yr with one trailer now which has a gross weight of 4,400lbs, this is higher as it's a manual car. That said it is rarely loaded to that level.
You raise an interesting point though about brakes. We use overrun brakes in the UK which are ok but not the best. I am very curious watching the video's and reading up on the US system of electric brakes. I like the idea of altering the bias depending on weight etc and think they offer a much better solution. Regarding tongue weight we generally have a lighter weight as it can impeded the overrun brakes if there is a lot of weight on the braking compression unit.
Still love the Forester. Great tow car although, if there's one problem is that 1st gear is quite high compared to my previous two VW Tiguan's. Thank you for your advice and thoughts.
The CVT in my Subie is awesome. So is the extended warranty I bought to back it :)
good thing I had the 60K ext warranty, My fucking forester needed all of it! overall Subaru is the POS I will never buy again, working good now after all the extra repairs I will go another 30000 miles then Get rid of it
Any advice on how to increase how many nm's it can handle?
Personally, I put a trans cooler to help with the temps as it didn't like the occasional track day. Will that help with longevity?
no
Good day, I have one question for you, I just busted my Impreza 2015 cvt transmission at 99600km. It would be replace under guaranty. My question: I often use the steering paddle to down shift when I arrived to a stop or to slow down instead of using the brakes. Is this a problem for the CVT along the time? Thanks for the answer. Alain from Quebec Canada
guess if it is a choice between a $3000 transmission (if not under warranty) or $25 brake pads, I would use the brakes!!!
Manual shifts and downshifts are harder on the cvt, or ANY automatic transmission. Just use your brakes…much cheaper to replace!
How much worse is the maintenance of this CVT compared to a discrete transmission?
Hello, how would you describe the noise from the input shaft bearing on the CVT? I have a brand new 2018 Forester XT that has a whirring noise that increases with RPM and changes pitch/harmonic with deceleration. I can pop it in neutral and rev it and the whirring follows engine speed so I believe it to forward of the CVT belt. Another I test drove after purchase had the same noise but significantly more muted to my ear. In your experience if these start to go, how speedy is the degradation?
you have the XT - it's probably the Turbo.!!
Hello, I have 2003 forester xt blown the centre diff, and I want to swap in 2005 xt gear box. Is there any problem with compatibility issues?
I agree Walter ,why do so much to save fuel when you chance breaking something more expensive than gasoline
Would it be possible to connect a brz transmission and rear driveline into a 98 gc8 making it RWD?
My friend took her car to the shop. They messed with the Transmission and the car started smoking when she got it back. They refused to fix it. She eventually traded the car for a Toyota because they do not break. Any idea what would make the car smoke really bad?
People like me LOVE the Subaru EXCEPT for worry about the transmission; the question is, what brand/model is a better choice?
Jmichael Isbell never ever can go wrong with Honda or Toyota 👍
Great video. It shows that CVT technology is just not there yet in terms of reliability. A transmission should not be failing after 3.5 years
Motuariki Dub I know I was thinking the same thing I got a 25 year old 4Runner with the original four speed still running strong as hell lol
This happens on any car, any history. Some failures are expected. I have seen this happen on tried and true technologies. Bearings sometimes come with defects, this is true even for high end wheel bearings for example. I had to replace a wheel bearing after 6 months because of a defect caused premature death by noise. (Which is all they noted here, it was noisy and would fail.)
And I've got a 2013 SSS Pulsar that I've given hell to with no problems. To suggest that one failed bearing in one transmission consigns them all the the dustbin is plain stupid. CVT is the future for non-performance internal combustion engine cars, which are 99% of cars on the road.
Depends how the guy drove it also
Hah! Tell that to Ford and VW owners. Their horrible DCT fail regularly and often.
YOU NEED TO SERVICE YOUR CVT EVERY 100 000 km that's all there is to it... ;)
You didn't tell us how to maintain or tell us how to drive properly to promote longevityfor this transmission. I think that's what people expected from this video. I'm an engineerbut I still would like to know if it's really OK to use the paddle shifters as I do or if it's betterfor the transmission to let it do it's own thing. I'm not racing but I live in hilly and snowyconditions so I need to gear down a lot. Is this bad for these transmissions?
My 2015 CVT already gave out. I might be trading it for a Toyota.
So, my question is how long will that metallic belt/chain last. Is it the same as a clutch. How much will it cost to replace the belt/chain? For me if it won't go 200,000 miles, no good.
It can go 300k+ if you change the CVT fluid regularly.
What is your verdict on these cvts?
CVT valve body issues are creeping up on imprezas, outbacks, and foresters I've found out recently. which is a $1200 - $1900 repair bill. I only know this now because my 2014 forester XT with 89k miles recently had a check engine light relating to transmission solenoid/TCC issues (p0700, p2763, p2762) while driving. Scary ordeal. I pulled over and got those codes before shutting off engine for 20 minutes. the CEL did go away on it's own, but that didn't give me any good feelings and may be a symptom of future issues. After a lot of research this weekend, it's most likely the valve body electronic "brain" that's faulty. this isn't uncommon in the Subaru CVT's...
I have a 2012 impreza. Got 140k, cvt took a shit. Yet all the while dealer kept saying theres nothing to do to it. BS fluid should have been changed.
The stock Subaru CVT cooler is a coolant based heat exchanger. My Forester coolant normally operates at about 198 degrees F once at operating temperature. That means the CVT fluid being routed through the exchanger is being heated to at least 198 degrees F. I have an OBD device and app that is showing my CVT running at 210-212 degrees F. This is stock.
I understand the exchanger provides a dual purpose, to heat the CVT fluid also, but it is my understanding CVT fluid supposed to be kept at 175 degrees F and 198 and up is too hot. Has this been a contributor to CVT failure in your opinion?
Typical CVT failure is not effected by trans oil temps, fitting a trans cooler will not make the trans stronger.
@@MRTPerformanceAustralia Interesting. If overheating transmission is not a cause for failure what is?
@@MRTPerformanceAustralia Not trying to make it stronger, just cooler so it won't overheat and cause the fluid to deteriorate.
really cool. I just leased a Legacy 3.6R with the High Torque CVT in it. interesting to see what its guts look like

That car must be fun to drive 😏
actually, it turned out to be horrendously unreliable and i just traded it in
The CVT was unreliable or something else?
Thx.
no, it was the car as a whole... very frustrating
Can you share what issues you faced? I really like the Legacy, but getting more and more bad reports from owners.
Sir , i got a problem with my levorg transmission. Is it possible to ship some parts overseas? Subaru here in our country wants to replace the whole system. I think its crazy
should I get a CVT to tune it to stage 2? is it safe to now or no?
"The part that I want to show you is what the gearbox looks like." Having no gears, no gearbox is needed! The ratios that the transmission changes are pulley diameter ratios. They are contained within a transmission housing, not a gearbox!
"This belt expands and contracts." No! The belt stays the same size at
all times. The same length, the same width. In order for the belt to
stay the same size, the functional diameter of the pulleys has to
change. As one pulley gets larger in diameter, at the place where the
belt makes contact with it, the other pulley must get smaller.
Pretty much like a snowmobile.
Help please!! Any advice on the Forester XT (2016) occasional hesitation under acceleration issue? Seems to sometimes hesitate under about 30%-50% acceleration (feels like maybe misfiring or cvt not engaging correctly). Issue is way worse with air con on!
I have a 2015 subaru wrx cvt. I need to upgrade my trans with the custom Cobb accessport tune I recently got done I can only get 300hp and 328 torque before the trans slips. I need this trans upgrade is there anything u can do. I'm located in the USA
The Subaru non-turbo cvt, when would you change oil?
I got a problem with my subaru xv crosstrec 2013 cvt, when the car rolling and push the accelration pedal any noise look like something splin. When we check the error code P0700 and P0841 What excaly the problem, and why the dealer say must replace the transmission assy?
I have a 2016 Forester with a CVT. The only problem I have with the CVT is the 2 second delay when you shift to or from reverse. This is a major issue if you are trying to rock the vehicle when you get stuck in snow. When I took the vehicle to the dealer to fix this problem the tech said that is normal and there is nothing they can do. He never talked about a "CVT relearn". Will the "CVT relearn" make the CVT act like a normal automatic transmission when shifting to and from reverse?
Best to upgrade Foresters that might get to drive on dirt, mud or snow to 'All Terrain & Snow' tyres - larger chunky knobs of rubber that won't get stuck in snow!
@@GraemeHarrisonAU , I agree tires make a big difference, but you still can get high centered and sometimes rocking the vehicle will get you out. Thats why I asked the question.
The older Subaru Transmissions had an external filter similar to an oil filter that could be changed easily on the outside of the transmission. To me the filter inside that cannot be changed without tear down looks like the sort of filter that will get dirty and clogged way before the strainer type in the sump. Sad to see and say but looks like a design flaw in my book. I love how the CVT drives though and would like a CVT Forester Turbo one day but the compromises are hard to swallow Subaru.
Putting a turbo with a CVT makes NO SENSE. One of the reasons is the CVT can't take it.
Was that bearing the cause of a loud grinding/reving noise? Having that issue on mine and very nervous about changing it out.
Interested in that too
1. I have heard that replacement parts and quality ones are currently hard to find, true?
2. If driven properly and quality fluid used/changed regularly, what is a reasonable expectation of duration?
3. Are these transmissions (or any automatic) made by certain companies and utilized by the different car makes?
This is an excellent and concise video with great filming quality!
I have a question....I have Levorg 1.6. Can TR690 be fitted instead of TR580 gearbox? I want to increase performance, but can the transmission tr580 handle 350nm of torque?
Hi there, I have WRX cvt 2015 and it has 25000 km , everything is great so far only today I noticed that the reverse is not engaging properly!
the car would back off very slowly , but when I hit the accelerator it behaves like it is on neutral and the engine shakes if I hit more and no reverse action is happening. can you please tell me what is wrong with it and what should I inspect ?
CVT baby إسماعيل
I have at poblem i have at 06 forester every time I drop to 3rd ...rpm are 4000rpm or 5000rpm the car star shaking any ideas
Cool video. I can't control myself though from feeling angry while watching this because all I can think of is the $2,000 this guy probably had to spend to fix this on what seemed like a fairly new car. He's probably still paying off the car and has this added expense now.
Does not give me a warm fuzzy feeling to go out and buy a Subaru.
Try that x3 or more... these things are not fun to loose and is why I'm here researching them for when I start towing occasionally with my 2016 outback.
@@darksd3626 on my third cvt in wrx 58k miles lol
@@don-cw1yz Unfortunately all makes are starting to incorporate this type of technology. Less duty time more shop time.
@@Keys879 Toyota does not seem to have issues with its CVT transmissions. Toyota made a great 6-speed automatic transmission. They are having issues with the new 8 speed though. Those are not CVT transmissions. Nissan makes garbage CVT transmissions, (Jatco is the Nissan brand).
Subaru seems to be using a link chain for the meat of the CVT, which is quite different to Jatco (read Nissan) units which relies on a thinner steel push-belt design (demonstrated here: ua-cam.com/video/PiwRUfFEc5k/v-deo.html). The contact area is a lot larger so hopefully Subaru has gotten the reliability down where Nissan still struggles in this department with belt snapping & wrecking the entire transmission.
