@@speedkar99 hi Great video. My situation. I have a 2020 Nissan Altima 51,179 a horrible strong burning smell was coming from inside car at times and outside of vehicle always. I never ever run it hard I keep it under 2.5 rpm’s. I bought car at 41,000 miles. I was curious to see how CVT fluid was doing so I pumped it out and I have the pics and it looks like cocoa cola. A strong burnt smell this was it. No engine indicators ever came up on for bad transmission etc. My concern is what if I didn’t change the fluid? Could the fluid have still lasted or would the fluid have caused serious problems and burned the surroundings of the steel belt??? I knew there is no exact answer or way of knowing. I really wonder how much more time of that burnt fluid especially with that strong pungent burnt smell could or would have damaged inside the CVT and what would the old burnt fluid damage specifically??

Why would Nissan do that?

No shit you think 120 hp cars can kill it quicker it’s got a punie engine 😂

[@vincentra8849]

Meaning belt isn’t the failure point. From my understanding w 190k mi on CVT and on the clock keep going. From 2011 2.5 Altima. Most failures come from lack of maintenance (every 25k to 35k fluid change), or excess heat(can be addressed with external cooler. Which also extends oil life about 10k more) and I’m driving this car under extreme condition. Just so you know. 120f AZ heat wouldn’t be any good for this tranny but yet it drives like a sewing machine and makes me smile whenever I get to the gas station. Just don’t forget that CVT suffers from extreme heat. And there are ways to make it run right. Before rebuilt is actually needed. Plus these can take some damages compared to automatic transmission where everything is actually gear. And run by hydraulics where kick down can actually cause more harm for the tranny than it should be.

Every day a poor soul calls with a Nissan or Toyota or Korean car with CVT Transmission problems and most of them are out of warranty and still paying for the car. They end up with a not usable car which they are still paying to the bank. As they dont have 7 to 8 thousand dollars that the transmission cost here plus instalation and re programing.

Had the same thought. Maybe this isn’t the most reliable but you can see the ingenuity in the design. I’m sure a reliable CVT could be produced if it wasn’t optimized only for low cost. For example the too-small cooler. That seems like a dumb decision made only for cost savings.

Thank you for this post. I have a 2013 Jeep Compass with the 2.4. I think this is the CVT that is in my car. Also, a few Nissan (of course) and some models of Subaru. My CVT started going bad at about 25K. I took it back to the Jeep dealership multiple times as it was still under warranty, and of course, they could find absolutely nothing wrong with my car. Then, when my Compass went out of warranty, miraculously, they discovered I needed a new CVT. I have been a Jeep owner since 1983. CVT or not, I WILL NEVER BUY ANOTHER JEEP AGAIN.

This can be mitigated with an external transmission and separate oil cooler. I would not "lump in" the 350z/370z into the same arena as the POS leaf/rogue/maxima/altima/sentra/etc that used the CVT's. Those things MUST have fluid changes every 20,000 miles, but, - Nissan failed in: 1) Training the dealerships to actually recommend, advocate, and encourage such service 2) Nissan failed in properly TRAINING the dealerships HOW to do this properly (there's nuances to it, so it's not just your "boring" every day drop fluid, fill fluid mindless mouth breather low iq I'm hungover on a friday braindead mechanic service move 3) Nissan decided to GAMBLE in that, it believed that owners would simply trade/buy another nissan before the 60k/5 year "powertrain" (stupid name but whatever) warranty would end. 4) Nissan underestimated the failure rate 5) Nissan decided to try to copy toyota/honda - in pushing volume/value > reliability - I'm sure many former nissan owners are now in Toyota/Honda products 6) The 370z/350z/GTR are still 100% designed/manufactured in Japan - I believe cultural differences actually DO still count, as I'm sure more US/Mexico manufactured vehicles have higher defect rates - while you can outsource to lower cost countries, that cost cutting eventually shows up somewhere. 7) Even so, "some" 370z owners have "experienced" 7AT (7-Speed automatic) transmission failure - some are racing, some are doing auto-x, some are doing road course, and some simply had a BOTCHED dealership fluid change after begging the dealerships to replace the fluid, and having received the LOW IQ / MOUTH-BREATHER "It's a sealed transmission.." speech. 8) "Not all" (I hate that phrase too, women use it too often haha) - Dealerships actually have on hand the "CONSOLT" tool used to increase transmission fluid temp, in order to PROPERLY change the fluid on the automatics for the 370z 350z's. 9) The 7AT has a design flaw in that Nissan/JATCO - decided to use rivets in certain areas causing uneven wear and failure. Also - the flex plate tends to crack/fall apart, causing debris to "work its way" into other parts of the transmission. 10) Nissan dealerships have some of the highest turnover rates among any vehicle manufacturers out there. So, every time you do bring your car in, you may see the same smiling "service managers" face, but, the dudes that actually do all the work all day long are usually high on drugs/alcohol/"new"/or on their way out. It's worse than your typical retail banking branch. I believe Nissan should put in place an aggressive retention and drug/alcohol/talk therapy program for anyone who works within the dealerships, and also not allow for > 50 hours per week; Simply provide better reasons for people to stay longterm so you don't get a DRUGGIE working on your vehicle who then thinks it's "funny" when you call as a customer asking for your car back after it's been 6+ weeks when you were told "2-3 weeks." So - my advice/conclusion: Anyone buying ANY automatic from ANY manufacturer - Just pay that additional $15 per month for a separate mechanical breakdown insurance rider. Do not play the: "It's not my first rodeo bucko!" and think for a MOMENT that your standard insurance policy will magically cover you. It won't. You MUST PAY EXTRA for a separate POLICY. Not all insurance companies even offer this. Do not confuse it with a retarded/moronic/pointless/overpriced/scams r us "extended warranty" either. Do not rely on the "stupid" "power train" (why is it called such a stupid name!?) "warranty." You don't want to be stuck driving a rental vehicle for 6-8 weeks while Nissan tells you "Yeah, we don't know where your new transmission is... we lost the tracking number..." You also don't want to be the ginnea pig either - as very very very few Nissan dealerships have experience actually changing / replacing the transmission SPECIFICALLY on the 350z or 370z. They have TONS Of experience on the other models, but, they will LIE TO YOU, and lump YOUR car into that group, and you'll be stuck with a retarded Nissan sentra for 6-8 weeks. Which - for the record - A school bus has better brakes than a stock 2019 "new" Nissan sentra.

[@laura-ann.0726]

Best deep-dive into a belt-drive CVT that I've seen. Thanks for the video! I can easily see why these fail: too much complexity. If the two pulleys fail to synchronize their diameters properly, the belt will be too loose or two tight, and it will break. The system is critically dependent on the oil being clean and of the proper viscosity at all times, or the hydraulic controls that actuate the belt pulleys won't work properly. The E-CVT transmissions used on hybrids and EV's are also CVT's, but there are no hydraulic actuators and no clutch packs. The "variability" part of the power equation in an E-CVT comes from the fact that the 3-phase electric motors that power them can provide a very flat torque curve from a dead stop all the way to full speed. So there only needs to be 1 gear ratio between the primary drive motor and the final drive differential. The failure modes of an E-CVT are almost all to do with the electrical components and computer controls, and these have been proven to be pretty reliable, at least more so than the JATCO belt-drive CVT we saw in this video.

[@bobwilson758]

Best CVT trainer I've seen! Brilliant video. With a 2.0 140ps engine my wife's is still going strong touch wood but I certainly wouldn't put it with a large vehicle, a V6 and a trailer, just doesn't feel tough enough

Agreed. Probably for a small city car or scooter

This is the EXACT transmission that I had fail on my 2005 Murano TWICE in 125000 miles. Thank you for making this and explaining the inner workings of these transmissions!

[@allhailzoidberg8182]

We had a 2008 Altima 2.5 that lasted 200k miles with the original transmission. We sold it to my uncle who is still driving it 60 miles everyday to and from work. I don't have any clue how that little transmission is still alive.

[@Dcbbanker]

Because it was a 2008. Nissans we’re more Japanese then. Now they’re Renault, mostly. Big difference. They’re trading off their old rep, and people are expecting the same from these new ones. And they are disappointed.

Thanks for taking the time to clearly explain how these work. This is an absolutely great explanation/demo of a CVT and its failure points.

When the Saturn VUE first came to market, I was a service consultant at a Saturn retailer. The CVT they put in the 4 cylinder models was a nightmare. If it was an all wheel drive, the problems were worse. After a couple of model years, they decided to return to a tried and true automatic transmission. And, they ended up buying back almost all the rest from deeply dissatisfied owners.

[@atomickeeyu2285]

Thanks for this great video! As an Honda with a CVT owner, you taught me everything I need to know to make it last. Very useful!

@@diegosc985 a friend has a 2014 Versa that's been horribly wrecked twice and most of the nearly 200k miles is cross country trips. Engine still purrs and transmission/shift assembly still feels vague and unsatisfying to shift just like new. It's impressively reliable despite the abuse.

[@NeoMorphUK]

I honestly don’t miss my stick shifts these days. If I want there is a semi-manual flappy paddle manual system on my current car but I had one quick go with it, found that the dash display tells you when to shift and then thought “if you are going to follow the car’s suggestions then you might as well be on auto anyway” and went right back to full auto.

[@fernandopenah]

Man, you know your stuff. Good explanation. Those CVTs are incredible complex. Can’t imagine the number of individual processes to make all those parts just for the transmission. Think about hoe many jobs a transmission creates for all the needed parts.

[@trentdaddydolla647]

Complex but easier to work on and they don’t require special tools to rebuild. Only problem is finding parts. Seems there’s a monopoly in them now lol

The 2006 Altima doesn’t have a CVT. They didn’t salary putting those in Altima’s until 2007.

Awesome job, video, and explanation. Wasn’t aware how complicated a CVT was until now. I have one in my 2014 Honda Civic, going to keep up with the maintenance on it for sure to hopefully avoid a catastrophe. Thanks again
