@@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??

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.

This makes cars totally disposables. No parts, you have to get the same transmission on warranty or if out of warranty pay for it and the service cost. And you get again the same problem, no thanks is better to get a new car with no CVT.

Thanks for taking the time to clearly explain how these work. We bought a 2010 Sentra new and it has 155k miles on it and still runs quietly and smoothly. I never changed the CVT fluid until the warranty expired at 120k miles. At that point I drained the gallon that comes out and replaced it with Valvoline's fluid. Drove another 10k and did it again. I did it a second time at 140k. So far, so good. I mostly use the car to commute to work at 80mph and have not had any issues. I can see how higher performance cars would eat up such a simple belt with too much power. I'm hoping our Sentra just keeps on running since the resale value is low, but the car still drives like it did 10 years ago.

CVT's are great for cruising long distances on the highway at 80 or 90 mph in a lightweight car. What seems to mess them up is racing full throttle from stoplight to stoplight like I see a lot of Nissan owners doing, especially in the heavier SUV's. I know it's fun to be able to beat Audis, Camaros, and noisy Subarus from light to light with your Murano, but if you do that a lot, you'll end up in my buddy's transmission shop with bad news. Those transmissions are not made for racing.

The CVT in my 2018 Maxima is incredibly fun to drive compared to other similar horsepower cars I've driven with standard automatics. I'm no mechanic, but I do know when you put your foot down the car goes like a rocket until you take your foot off the gas. There's no jerking through gears, just seamless and smooth acceleration. I know everyone hates them, but I like how they drive. If it fails, it fails. My 2014 Tacoma transmission, which is supposed to be bulletproof, died after only 115,000 miles with regular scheduled maintenance and never towed anything with it. Also the rear leaf suspension rusted out and squealed, the frame rusted through and it was garage kept. All these videos make it seem like these CVT transmissions are failing left and right but I see more 5 year old Altimas, Maximas, rogues, and muranos on the road than almost any other car.

But ive had a 07 nissan sentra with a CVt that works well enough That being said the Op is the second person ive seen that mentioned how fast the CVTs change ratios and ive never seen that happen both a 12 maxima and my 07 sentras go through the ratios really slow compared to my 2011 fusion and my partners 2018 330I BMW, especially on kick down.

If you have vq35 or similar, it's simply too much power for such a trash transmission. You've been lucky, My 2012 maxima 350 transmission was serviced regularly and it still failed, crazy quotes to replace transmission even if i could find one with low km's or in better cond than the old one. Even my mum's Juke which has a cvt is starting to show signs of transmission issues and she has been gentle as with it and religiously had it serviced at Nissan. At least a regular transmission can be repaired if it fails and it doesn't spell the end for the car. Obviously it won't bother you until your car becomes a lump of scrap metal because of one aspect of the car failing due to bad design.

Manufacturers are constantly coming up with ways to make these things unserviceable/DIY-able. The manufacturer (through dealerships) want more of your money spent on their product. If it's not buying parts/repairs it's buying another vehicle.

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.

Great video and presentation, Masterclass. Best advice I've read has been to get in there every 40K and replace the trans fluid with a good synthetic. Don't follow the Nissan spec'd duration for that.

[@speedkar99]

You are welcome 😁. I have another CVT video for that Murano transmission if you like to see it.

Nissan should put you on their payroll! A brilliant description of the CVT.

[@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]

Well said !

[@tommurphy4307]

clean oil and proper viscosity counts for a lot- even in a conventional automatic. thats enough jatco-bashing for one night. one thing to remember- in 1970, datsun saved us with jatco automatics- saved us from borg-warner (letchworth UK).

[@Hector_Malot]

The Variomatic Daf transmission was developed in 1958 and found on Daf cars, it worked very well, it was a simple system and it is still in use today.

[@mistersunny3636]

Some of them went the same speed forwards as backwards. So we had reverse races back then with the DAF 66.

[@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.

[@spol1622]

@@air-headedaviator1805 well, if you repair things for a living (I do), you get the idea what fails most frequently, and what is the cause of failure. After some time, the patterns develop. When you are describing patterns from your memory only, your opinion is not worth much. In order to get your personal bias and your memory problems out of the equation, you need to back up your opinion with hard data (like the computer entries about failures in the last 5 years for a particular car model). Once you have done it, your opinion becomes a reliable source of information.... I'm pretty confident that this guy knows what he is talking about, and he most likely looked at hard data in forming his opinions...
