Sadpants McGee Well it's meant for people who already really knew what was going and what CVT was. Maybe there was a clip before that explained it before this was edited or something to make it clear.
Sadpants McGee This is user uploaded content, not official. The video isn't explaining CVT so much as it's highlighting an advantage of CVT. Officially it might have followed a video on the transmission itself, then this was to show why CVT makes a difference in comfort.
Admittedly as much as i hate cvts I do drive a maxima and what the video shows about engine braking is pretty accurate, cant say so much for the drunk AT guy tho
It allows you to coast for a few seconds if you let off the gas (as if the car was in N gear) but then engine braking kicks in. It's pretty much one pedal driving if you drive at a relaxed pace. Ofcourse if you drive like a lunatic, you need the brakes though.
I have a CVT And I haven’t had to replace it at all and my car has 237k miles on it and it’s 2007 💀 you guys either drive your cars like they’re race cars when they’re NOT or you can’t drive worth a damn and fuck the car up by hitting stuff
because its an exaggeration which is pretty corny in the four-cylinder that's paired with this transmission is very sluggish and doesn't have the power shown in this unless you step on it pretty good.
+Michael Russo I have to press the sport button every time I drive because it lessens the sluggishness of the small engine with the bigger body car ''Sentra'' it needs a 6 in it Stat!
No its not a Corolla either. Nissan doesn't own the rights to the Corolla. It looks to me more like the 2006 Nissan Sentra with a 4 speed automatic transmission hooked a 1.8 liter with 4 bangs for every revolution of the crankshaft. The CVT car is Nissan's 2007 Altima with the 2.5 liter I-4.
Cvts are very good at climbing n going down hills..i drove one up a mountain and i didn't have to rev past 3k rpm during the climb..the low end power is great(linear torque)..unlike an auto trans where you have to rev so high to get power(due to constant upshift/downshift of the torque conv)...and it is also true when going downhill, less braking is required ...cvts r very effective in these aspects.
I have a honda city with earth dreams cvt transmission. Its a pleasure to drive uphill going at 60-80km and when your going downhill you can drive it with confidence.
Yeah, whatever. It's your money, buy what you like. Can you explain why they have the worst reliable rating for the CVT and countless consumer complaints for failure? Enjoy your Nissan.
Nodak81 until my 310hp Maxima does 0-60 in 5.6 seconds while looking good and having a luxurious interior. 60k miles and it still runs like it's brand new. Never had one service.
frilink You see it as a car, just a vehicle, something to get to point a to b, how your day at work maybe more important to you then what gets you home. But some of us like to peek out the window to look at that vehicle that gets us to point a to b, some of us like cars because they are all different and unique and are made in all sorts of ways and have a certain appeal and feel to them, especially the cool looking cars that are fast and make noises that you can’t explain but you get a rush from, feeling it’s power and hearing it roar, each,in their own way , some us drive cars that are more important than are day at work, you understand?
I can tell you that my Sentra has great downhill braking with the CVT and the overdrive set to OFF. I don't even need to use the brake when driving down a mountian road; in fact, I sometimes have to use the accelerator to speed up the car on a downgrade with the O/D set to OFF.
I don't think this is an accurate comparison between AT and CVT. The AT car in the video was just demonstrating poor pedal control, not how good drivers would drive their AT cars. (i.e. who would change gears when passing another vehicle at high speed? Why would you have to brake before entering a bend when you are at the right gear?) CVT also makes the car sounds like it has slipping clutch. Toyota has just made the biggest mistake with their 2013 Corollas - switching to CVT.
paddle shifters in cars with the CVT transmission are there for people who track their car so they can control the RPM through a turn then when it switches back into D(not simulated manual mode) you can get back to making peak power quickly and its there for the kids who want to feel sporty and shift their car manually even though their car is fasted in D
Actually small 4 cylinder cars are a lot more fun in stick than auto or cvt because you can get the most out of the car and it can actually sometimes be more fun than a proper sports car because you can have fun in the confines of the speed limit
***** Yeah, its usually just a vacuum that holds the throttle at a certain position. Now on more modern cars its done through the on board computer telling the fuel injection what to do. It's throttle over transmission.
integra_ls_express actually the Nissan accord sedan base model for like 12k has a 5 speed manual with no cruise control. Kinda actually considering one in case of heavy weather I don't wanna deal with on the motorcycle.
The key bit is the cutaway with the pulleys. Here's what happens. Imagine you've got a pulley, with a V-shaped groove, and cut that in half. Half of it can now move in and out. Then there's a belt in there, and as the gap widens and closes, the belt moves farther from or closer to the axle, changing the ratio. A computer controls the pulleys and thus the ratio. It's a damn good idea but I kinda doubt its longevity... it relies on friction to transfer power, but fights friction to shift.
CVT is a great technological breakthrough. Yes, if you are used to racing and jack-rabbit starting and stopping, you don't want it. I have a 2013 Nissan Altima with a CVT in it and it is flat out amazing. Although it only has a 4 cylinder engine it runs like a top and has plenty of acceleration. On top of that, I can get 40 MPG on the highway! Yes, that is not a typo. AT 70 MPH I have gotten 40 MPG consistently. When I run 75-78 MPH it drops to around 36. They are great!
I have certainly driven quite a few cars in my short 6 years of driving... In fact I don't get stopped by my engine in with my 6-speed manual transmission and I love that.
I've driven one of those before without the knowledge of knowing about CVTs and it was strange couldn't put my finger on why the transmission was staying at a straight rpm upon long acceleration but it was amazing
just rented a altima with cvt. don't feel like the acceleration as good as the AT one's. I felt CVT is noisy and slow. this video shows the AT shifting likes manual.
Not all CVT's are bad, Nissan and Jatco (their transmission company maker) is though. Toyota makes their transmissions with Aisin for their Prius' and they're reliable.
@oscarfish48 It doesn't need to be replaced. It's a steel belt, more in tune with a timing chain than anything. And yes, in general, they are longer-lasting than most automatics. Not quite sure about standards, though, as unless driven too harshly, a lot of them are bulletproof.
How reliable are cvt transmissions? As in durability? Would I expect to get longer life out of a car with a cvt or a regular automatic? (assume regular maintenance and normal driving habits that do not involve flooring the gas pedal at all)
People are always concern about acceleration and about speed. Something they don't take in consideration is that when an auto movible Company like Nissan or Toyota decide to instal a CVT transmission in their vehicles is for a reason. Nissan and Toyota are top quality economy cars in USA. I personally like the feel of the CVT in my 2014 corolla. It feels smoother and i don't like the feel for the gear changing in a 4-speed automatic. The best part is the increase of fuel economy I noticed on the CTV. Hey is al about going from point a to point b.
They decided to use CVTs because they are cheaper to manufacture and they claim they reduce the emissions... Now i don't know if that reduces emissions in manufacturing or driving... If its a corporation, they do it for 2 reasons... 1 its cheaper or 2 because some government guideline says they have to. CVT's main point of operation is a V-Belt. Slightly modified of course...
The CVT transmission is not new technology. Its been used on scooters, mopeds, and go karts for years. They recently started using them on new cars. The 8 speed transmission is another attempt and comfort and efficiency. The debate here is whether CVT's are reliable. Back in the 60's GM introduced the Power Glide which was a 2 speed automatic as an attempt at smooth acceleration. I think CVT's have mastered smooth but I just cant see them in anything bigger than a sub-compact car. Cooper uses them in thier Mini's but if you have the turbo option you have to take a 5 speed manual because the CVT cannot take the torque... Do some research before you make condescending remarks.
makinbac0n I personlly think they are the transmissions of the devil. Having the RPM sit at x RPM not overly efficient mainly because they sit at the peak HP rating and Horsepower is not what makes cars move. it is torque. Torque is found lower down on the RPM band.
Damn, after watching this I have learned that CVT's are the best transmission in the world, they accelerate faster and require no braking, time to contact all race teams and tell them what they are doing wrong.
+Teddy Monroe Actually you really dont have to break downhill with a CVT..... you lift of the accelerator and the motor breaks. The CVT "downshifts" so the revs still stay at the top range for e.g. 6000 rpm. The slower you get the more it changes the "gear" ratio to keep up the motor breaking. But still the video sucked :D
With a MT yes, your run of the mill OT, not always. MT and CVT have excellent engine braking, AT not so much, so if you get a bit too heavy on the acceleration braking's your only option.
@WXIIIR They are showing the rate of acceleration of CVT vs Automatic transmissions, also they are explaining how CVT doesn't have shift shock like Automatic cars do
And they wear down pretty quick. In terms of fun, well lets just say cvt is for people who see cars as little more than transport or are mechanically illiterate.
I have a cvt trans. in my 07 nissan sentra. About how many miles should the transm. fluid be changed or does it need changing at all? Thanks for the video.
matt wood hopefully not mate but Ive got 3 years or 160000 klms warranty so if it goes in the 3years I own it as I won't put that many klms on it all good covered by Nissan dude and I get rid of my car's every 2 1/2 years so it sells with warranty. That way I never pay to replace or repair them😀👍
@TheArcticcatrider Well nissan's Xtronic CVT is electronically controlled, it keeps my cube at 1500-2000 rpms when ever im not on the gas which is lower rpms then both my old cars with 5 speed manuals.
CVT was first invented in Germany in the 50's so it's hardly new technology anyway, its just been refined and its main function is efficiency since you are never wasting energy by revolutions in between gears, it will never beat a manual for speed of course as you can downshift and make the pistons dance on the bonnet to get the speed.
But... the thing is, on a cvt, you are always on relativly high rpm, compared to a well driven manual.... so basically, you´re using MORE fuel instead of less...
Okay. but that still takes the advantage from it. basically, what you are saying is, that you are roughly at the same rpm on highways and in cities, as on a manual, if driven correctly. But, the manual and automatic got the advantage of high torque and power outputs. So, all in all, the cvt still is a relativly good idea but just doesnt work the way the inventors intended, at least on big cars and engines.
Distinct Lach No, it's an observation that requires more info from the person who made the comment, not from someone inferring what he thinks they meant; more CVT's being repaired could simply be the result of more of them being in use - what kinds of repairs and at what mileages...that would give an indication if they're "always breaking down."
Exactly. Way too many anectdotes and very little actual data. Considering people only talk about CVTs when something goes wrong, they tend to be skewed. We need to see hard numbers comparing failure rates between different transmissions.
My mechanic said if you change the oil of the tiny each 60xxxx miles you'll be fine . I just bought Nissan centra 2007 134xxx milesI 'm worried about it cause everyone says cvt is bad .if you guys have one of diiisss let me know how is it .thanks 🤕
+Wall E The problem with the CVT is the torque demands on acceleration from low/no speed, so you have a point. I do think this down side will go away as the technology matures tho. Once the car hits it power band tho, the transmission is ridiculous. It eats both AT's and manuals for breakfast from a rolling start, because you don't need to shift, it just maintains your powerband.
I had a rental Sentra a few years back that had a CVT. I was not familiar with them at the time and didnt know the car had it when I rented it. I just remember looking it up after I absolutely couldnt stand the way the car drove. I remember experiencing horrible acceleration and the car would just sit at redline under WOT and accelerate so damn slow. Regular automatics accelerate much better which made this video a complete joke. CVT's are good for just putting around town if nobody else is on the road and you never have to accelerate quickly.
It takes a little getting used to but once you learn how the trans/throttle position work together it feels like it's slipping at wot. Let off the gas and It'll pull hard.
Craig Weida you are correct I personally have driven a CVT for 7 years now and can confirm that the car accelerates the best and quickest with the gas pedal right under WOT.
I own a 2013 Camry Hybrid with CVT, after owning a Japanese manual car for 20 years. I have to say, I was very skeptical before I drove one, however even when I plant my foot, there is zero slip, and the feeling of zero gear changes is worth it.
@Tuneman1984 The point of the video is to look at the transmission. They simply exaggerate effects on suspension to show deceleration from braking and disengaging gears. Even with new transmission, an AT vehicle will still have to shift gears and therefore disengage from the drive shaft.
CVT, it's a garbage. I have a nissan sentra 2013 SR and have a drive issues and nissan can't find the problem. Sometimes when you press on the accelerator, the car in drive nothing happen.
Your gearbox goes into emergency mode. This is happens due to lack or poor service done to your cvt. You must change oil every at least every 15k km. In the cvt there's also 1 to 2 filters, you must change them too. And at the end you need to clean the radiator in the gearbox.
Not at all, stay away from the Nissan CVT. I'd personally love to buy a Nissan but one google search of "Nissan CVT Problems" will keep me from ever buying one.
Soon all cars will be using CVTs Chevy is talking about using it in the next Camaro's, I have one in my Nissan and honestly not a big fan but it does help out on gas
Even a bad driver can drive well with CVT-transmission. However a good driver will compensate the manual transmission's adversity by planning ahead not just the 100 feet of the bad driver, but a whole mile ahead. As such a good drive doesn't need to brake at all when driving on a winding road.
it looks like they applied the clutch used in snowmobiles (for decades) to the inside of a transmission. it works but its just reapplying old tech from what i can see.
Ok i have a 2007 Nissan maxima se and the take is pretty slow how ever once u get up to about 40 an floor it it takes off, so no prob there, but it wont go pass 120 is this bcuz of the cvt?
usually. all other things equal (internal resistance, quality, ect..) the cvt would destroy any other transmission. it just hasn't been done yet because who wants a supercar with a cvt? (speaking like i'm marketing to car people)
@control177 they are basically use the same however, each one serve a deferent objective. While the scooter's cvt helps to maintain lower maintenance cost and better fuel economy, the xtronic cvt adds better response, gear shifts that are shock free and then optimal performance at all conditions as opposed to normal expensive and (harsh) auto transmission. I'm not an expert but basically this is it.
you do realize that all manual vehicles engine brake all day long everyday. if anything it's good for the engine to have all sorts of forces on it to even out wear and keep things under pressure.
***** the ZF 9 speed will out last any CVT any day, and hold more power and is 100% electronically controlled. basically its bullet proof from the factory. and ZF is one of the best transmission manufactures on the planet. You have no idea what your talking about..
how come when I drove a Nissan with a CVT it behaved like it had gears? under hard acceleration I expected it to stay at fairly high RPMs but instead it went up to redline then shifted down a lot then kept on rising to redline as if it had gears. from my driving experience I felt that I could have made the gearbox work much better for both speed and efficiency if i had manual control of the ratio.
Larommi71 You don't even need sport mode for that. The 4 cylinder Altima has a manual mode, but does not have the sport shift mode. You have to upgrade to the V6 model for that, and it's really just more aggressive ratio selection to keep the engine in its performance powerband rather than the usual fuel saving rules. In fact, you engage sport mode by moving the shifter into manual and then back into automatic.
Its not that the car slows down or the speed drops but, normally a car when it changes gears it pauses a second and does not go any faster threw the shifting which most people don't notice because it happens so quickly.
This is a propaganda film. I really hope people aren't fooled by this. The CVT was designed with one thing in mind: making a cheaper part while charging the customer more.
I would think that because CVT's are always high on revs where the maximum torque is, the wear and tear is higher than in a vehicle that uses a double clutch gearbox or manual one. Other than that, efficiency wins in a CVT
Nissan CVT's are the worst in terms of reliability and programming. No other manufacturer has as many complaints logged against them as Nissan has. JATCO is not reliable and Nissan has these transmission programmed to maximize fuel economy while making the car seem like it's 10 years old and falling apart with acceleration problems and lugging. Up hills the car sputters. Yeah, Nissan states this is NORMAL. I'll stick to planetary gear driven. Keep the CVT's in the hybrids where they belong.
A CVT works like a bike except the fact that instea dof shiftingk to a bigger gear to go fastes the whole roller that the belt is on gets bigger. When they use the manual mode it is just programmed tomake it "seem" like you are shifting by raising and lowering rpm and the roller thats the belt is rolling on. So they arent actually shifts. Youusually have to use the manual mode when you need to go higher speeds from a cruising speed of about 60 or so. hope that helps
CVTs use hydraulic pressure to move the wheels. When you floor it, all does is keep spinning the pump and generating pressure. If you stop the pump or slow it down, the transmission puts on a halt. So, downhill it does slow it down a lot. But if you want to vehicle to keep going you have to have engine spin the pump. Therefor, there is no disconnect from the transmission ever unless you put it in neutral and in turn disconnect the pump from the axle. Smooth acceleration is true about these vehi
CVT is theoretically the superior of any transmission to ever be invented, whether it be for fuel economy or acceleration. People just don't like it because it takes out an element of driver interaction. But, since they don't want to admit that, they like to say that it sucks because it isn't as durable as other transmissions, which is true, but still.... With some more research into making them more durable and cheaper, CVTs will objectively be the better transmission.
You don't know what you're talking about as long as you do your maintenance any transmission should have zero problems unless there is a defect cvt transmissions simply require a more regular service for them to operate correctly. I love going and shopping for a used car and asking people when the last time they had the transmission serviced.... generally the answer is "I don't know" aka "your supposed to do that?" Her dur dur
whats the difference between it and my scooter's cvt? to me the automatic transmission just looks like it would last longer cuz of its planetary gears and hydraulic clutch system not wearing out as fast as the cvt belt.
This didn't explain jack shit. And I'd really like to know why the standard auto driver was riding the brake for no reason.
Sadpants McGee They're trying to show the acceleration difference between a car shifting up and down and a CVT.
SnipinCatz It might *show* it, but it sure as hell doesn't *explain* it.
Sadpants McGee
Well it's meant for people who already really knew what was going and what CVT was. Maybe there was a clip before that explained it before this was edited or something to make it clear.

It allows you to coast for a few seconds if you let off the gas (as if the car was in N gear) but then engine braking kicks in.
It's pretty much one pedal driving if you drive at a relaxed pace.
Ofcourse if you drive like a lunatic, you need the brakes though.
a cvt will make you go faster to the workshop.

Why does the demonstration of the automatic look like it's shifting like a manual transmission...
because they have to use a shitty AT to compare against the CVT.
Because that is how Nissan AT shifts...

How much worse is the maintenance of a CVT compared to a discrete transmission?
The key bit is the cutaway with the pulleys. Here's what happens.
Imagine you've got a pulley, with a V-shaped groove, and cut that in half. Half of it can now move in and out. Then there's a belt in there, and as the gap widens and closes, the belt moves farther from or closer to the axle, changing the ratio. A computer controls the pulleys and thus the ratio.
It's a damn good idea but I kinda doubt its longevity... it relies on friction to transfer power, but fights friction to shift.

That's right kids, CVTs make it so cars require no braking whatsoever!
Nissan, what is this bullshit?
On a hill the transmission controls the speed of a car. Like downshifting in a manual.
It's called engine braking you dingus.

It feels smoother and i don't like the feel for the gear changing in a 4-speed automatic. The best part is the increase of fuel economy I noticed on the CTV. Hey is al about going from point a to point b.
wait til it breaks on you, they're very unreliable, UA-cam has a lot of videos of new cars with broken CVT systems
They decided to use CVTs because they are cheaper to manufacture and they claim they reduce the emissions... Now i don't know if that reduces emissions in manufacturing or driving... If its a corporation, they do it for 2 reasons... 1 its cheaper or 2 because some government guideline says they have to. CVT's main point of operation is a V-Belt. Slightly modified of course...
Your fault for having a car from the 1990s.
5 speed autos came around after 2000, they now have 6 speed autos.
Some even have 8 speed autos.
The CVT transmission is not new technology. Its been used on scooters, mopeds, and go karts for years. They recently started using them on new cars. The 8 speed transmission is another attempt and comfort and efficiency. The debate here is whether CVT's are reliable. Back in the 60's GM introduced the Power Glide which was a 2 speed automatic as an attempt at smooth acceleration. I think CVT's have mastered smooth but I just cant see them in anything bigger than a sub-compact car. Cooper uses them in thier Mini's but if you have the turbo option you have to take a 5 speed manual because the CVT cannot take the torque... Do some research before you make condescending remarks.
makinbac0n
I personlly think they are the transmissions of the devil.
Having the RPM sit at x RPM not overly efficient mainly because they sit at the peak HP rating and Horsepower is not what makes cars move. it is torque.
Torque is found lower down on the RPM band.
Cvt transmission has a great handle good shifts in really fast 3.5 v6 yesss
the mechanism that replaces it may be a (torus) toroidal transmission or metal band is shown at the beginning
Damn, after watching this I have learned that CVT's are the best transmission in the world, they accelerate faster and require no braking, time to contact all race teams and tell them what they are doing wrong.
+Teddy Monroe Actually you really dont have to break downhill with a CVT..... you lift of the accelerator and the motor breaks. The CVT "downshifts" so the revs still stay at the top range for e.g. 6000 rpm. The slower you get the more it changes the "gear" ratio to keep up the motor breaking. But still the video sucked :D
+DxCBuG You can also do that with manual and autos by shifting it into second.
chrischoy9 thx...i knew.. i drive a stick shift... greetings from germany
DxCBuG Good man
DxCBuG sounds healthy
Why would you brake when passing a truck?,
You over take and slip back in
With a MT yes, your run of the mill OT, not always. MT and CVT have excellent engine braking, AT not so much, so if you get a bit too heavy on the acceleration braking's your only option.
James Marlin
AT should change gear at or before the redline,
If you cant judge distances to make a safe overtake, dont do one.
James Marlin in some AT cars, we can manually select lower gear to increase acceleration & engine braking
Muhd Iqbal
I have not come across any AT that only has P R N and D.
My first auto had P R N D4 D3 L
IIGrayfoxII my cousin's car has P R N D L only
how often does the belt in a cvt need to be replaced? does it have a longer life than automatic or standard transmissions?
@WXIIIR They are showing the rate of acceleration of CVT vs Automatic transmissions, also they are explaining how CVT doesn't have shift shock like Automatic cars do
why does everyone hate cvt? just found out about it and it seems really cool
well the main reason. you dont have a fun car anymore.. its just CVT
And they wear down pretty quick. In terms of fun, well lets just say cvt is for people who see cars as little more than transport or are mechanically illiterate.
Civic13Man Gaming But if you want fun, get a sports car, I am not a big fan of CVT's but those cars get you from point A to B comfortably!
J.A. Castillo yea but really any regular oldcorolla still has something to play with. with cvt its pretty much the car doing all the work for you
Civic13Man Gaming except if u have a snowmobile then u have fun with a cvt
CVT equates to automotive cancer
+SuperNiceguy60 you can't run away from technology
Nor can u drive away, if what u have is a Renault /Nissan Altima known for breaking down anyway.
TruAgape1234 that's because people don't do maintenance!!!!!!
The idea of CVT is perfect, but the current state of technology is not up to the task.
i have a 2003 nissan murano that seems unusually slow i'm thinking the cvt transmission fluid needs changed.
I have a cvt trans. in my 07 nissan sentra. About how many miles should the transm. fluid be changed or does it need changing at all? Thanks for the video.
this illustration is very true
I prefer 5 speed manual or auto
Where is the animation for when the cvt failes at 50k miles and leaves you stranded. Or the jitter and whine it produces
matt wood 3 years factory warranty mate
Wayne Fox will fail possibly before but usually starts at 60-70k miles. 4 people I know all had issues with these Nissan cvt
matt wood hopefully not mate but Ive got 3 years or 160000 klms warranty so if it goes in the 3years I own it as I won't put that many klms on it all good covered by Nissan dude and I get rid of my car's every 2 1/2 years so it sells with warranty. That way I never pay to replace or repair them😀👍
@TheArcticcatrider Well nissan's Xtronic CVT is electronically controlled, it keeps my cube at 1500-2000 rpms when ever im not on the gas which is lower rpms then both my old cars with 5 speed manuals.
very helpful...thank you
so that pulley based transmission piece with the belt looks an awful lot like the clutch system used on snowmobiles for decades, #newtech #yearight.
CVT was first invented in Germany in the 50's so it's hardly new technology anyway, its just been refined and its main function is efficiency since you are never wasting energy by revolutions in between gears, it will never beat a manual for speed of course as you can downshift and make the pistons dance on the bonnet to get the speed.
But... the thing is, on a cvt, you are always on relativly high rpm, compared to a well driven manual.... so basically, you´re using MORE fuel instead of less...
That would depend on whether the control system for the cvt is programmed towards power or efficiency.
you're not always on a high rpm, a good CVT will have an overdrive function.
Okay. but that still takes the advantage from it. basically, what you are saying is, that you are roughly at the same rpm on highways and in cities, as on a manual, if driven correctly. But, the manual and automatic got the advantage of high torque and power outputs.
So, all in all, the cvt still is a relativly good idea but just doesnt work the way the inventors intended, at least on big cars and engines.
Nearly all of the automatic transmissions that we fix/replace at work are cvt...
Is that a good thing or a bad thing?
+atticstattic bad thing, it means cvt transmissions are always breaking down
Distinct Lach No, it's an observation that requires more info from the person who made the comment, not from someone inferring what he thinks they meant; more CVT's being repaired could simply be the result of more of them being in use - what kinds of repairs and at what mileages...that would give an indication if they're "always breaking down."
Exactly. Way too many anectdotes and very little actual data. Considering people only talk about CVTs when something goes wrong, they tend to be skewed. We need to see hard numbers comparing failure rates between different transmissions.
ces boites CVT étaient surtout des boites a 4 rapports.
La Hyundai grand i10 BVA a une boite 5 rapports est- ce une boite CVT aussi ? Merci.
My mechanic said if you change the oil of the tiny each 60xxxx miles you'll be fine . I just bought Nissan centra 2007 134xxx milesI 'm worried about it cause everyone says cvt is bad .if you guys have one of diiisss let me know how is it .thanks 🤕
CVT performs better on V6 engines. On 4 cylinders, its garbage..
+Wall E Once drove a 2014 Chevy Spark rental with CVT it was not nice. Scary when trying to overtake.
+Super XR what about manual CVT? I'D TAKE THAT
+dligac Wait what? manual CVT?
+Wall E The problem with the CVT is the torque demands on acceleration from low/no speed, so you have a point. I do think this down side will go away as the technology matures tho. Once the car hits it power band tho, the transmission is ridiculous. It eats both AT's and manuals for breakfast from a rolling start, because you don't need to shift, it just maintains your powerband.
+Super XR you drove a Spark...with 89 horsepower.....what did you expect to overtake? Lol
LMAO! That AT looks more like a Manual transmission! A AT car doesnt shift like that!
I'm driving a rental Nissan Maxima with CVT and I like it better then my AT. The acceleration is awesome.
Nissan CVT are great, i have nissan van with cvt and its very comfortable to drive 🚐👍🏻
How's the gas mileage?
Luke Pakseresht its just fair, depends on how i drive it
I had a rental Sentra a few years back that had a CVT. I was not familiar with them at the time and didnt know the car had it when I rented it. I just remember looking it up after I absolutely couldnt stand the way the car drove. I remember experiencing horrible acceleration and the car would just sit at redline under WOT and accelerate so damn slow. Regular automatics accelerate much better which made this video a complete joke. CVT's are good for just putting around town if nobody else is on the road and you never have to accelerate quickly.
exactly. i agree got a 2016 sentra cvt and this video must be a joke.its slow like a turtle.
The Adventure Mazda
It takes a little getting used to but once you learn how the trans/throttle position work together it feels like it's slipping at wot. Let off the gas and It'll pull hard.
Craig Weida you are correct I personally have driven a CVT for 7 years now and can confirm that the car accelerates the best and quickest with the gas pedal right under WOT.
That car has probably worn out CVT or roller weights
MT < AT < CVT?
Nathaniel Morada turn those arrows the other way
Fuck
Your R1M looks sick.
I own a 2013 Camry Hybrid with CVT, after owning a Japanese manual car for 20 years. I have to say, I was very skeptical before I drove one, however even when I plant my foot, there is zero slip, and the feeling of zero gear changes is worth it.
I agree with the Japanese companies doing this because they never can design a proper regular auto.
@Tuneman1984 The point of the video is to look at the transmission. They simply exaggerate effects on suspension to show deceleration from braking and disengaging gears. Even with new transmission, an AT vehicle will still have to shift gears and therefore disengage from the drive shaft.
CVT, it's a garbage. I have a nissan sentra 2013 SR and have a drive issues and nissan can't find the problem. Sometimes when you press on the accelerator, the car in drive nothing happen.
Your gearbox goes into emergency mode. This is happens due to lack or poor service done to your cvt. You must change oil every at least every 15k km. In the cvt there's also 1 to 2 filters, you must change them too. And at the end you need to clean the radiator in the gearbox.
CVT is reliable ???
it is on my car but I hate it.
no
nope Nissan is in deep lawsuits also chevy
70,000 miles in into my Nissan maxima 2012... still reliable .. its just alot of haters outthere ...
Not at all, stay away from the Nissan CVT. I'd personally love to buy a Nissan but one google search of "Nissan CVT Problems" will keep me from ever buying one.
Soon all cars will be using CVTs Chevy is talking about using it in the next Camaro's, I have one in my Nissan and honestly not a big fan but it does help out on gas
Even a bad driver can drive well with CVT-transmission.
However a good driver will compensate the manual transmission's adversity by planning ahead not just the 100 feet of the bad driver, but a whole mile ahead. As such a good drive doesn't need to brake at all when driving on a winding road.
why do people hate on cvt its a genius way for everyday car also less complex even engineering explained thinks its a brilliant trans
+Muammarvsgaming 00 I also can't understand it. CVT is MUCH simpler they AT.
i also has many potential
it looks like they applied the clutch used in snowmobiles (for decades) to the inside of a transmission. it works but its just reapplying old tech from what i can see.
the idea is good, but the execution has yet to be improved.
You'll hate it when you're $5,000 when it breaks down right after warranty expires at 60,000 miles.
CVT transmissions are awesome!
There's no tow truck in this video collecting you from beside the road when it fails...
Ok i have a 2007 Nissan maxima se and the take is pretty slow how ever once u get up to about 40 an floor it it takes off, so no prob there, but it wont go pass 120 is this bcuz of the cvt?
in reality this does not happen Nissan try racing your 02 maxima manual or auto vs your cvt garbage that has the world of problems
Aren't cvts slower because theyre mostly shitty cars?
usually. all other things equal (internal resistance, quality, ect..) the cvt would destroy any other transmission. it just hasn't been done yet because who wants a supercar with a cvt? (speaking like i'm marketing to car people)
Heard F1 had a car awhile back with the cvt.
@control177 they are basically use the same however, each one serve a deferent objective. While the scooter's cvt helps to maintain lower maintenance cost and better fuel economy, the xtronic cvt adds better response, gear shifts that are shock free and then optimal performance at all conditions as opposed to normal expensive and (harsh) auto transmission. I'm not an expert but basically this is it.
do you know how a skidoo clutch system works ? im sure ya do well cvt is the exact same just has a trany casing covering the unit
yea sit there and do engine breaking everyday and see how much maintenance you'lle need
you do realize that all manual vehicles engine brake all day long everyday. if anything it's good for the engine to have all sorts of forces on it to even out wear and keep things under pressure.
Engine braking is harmless if you don't rev over the redline. Heavy trucks use engine braking.
That's the only way I break when I drive my ex...
As much as CVT are garbage, I'd take one of them over the Chrysler 9-Speed anyday.
***** It's overkill I agree.
But you get better fuel economy
***** No, the CVT still gets better fuel economy.
***** i meant that you get better fuel economy with 9 gears instead of like 4 :/
***** the ZF 9 speed will out last any CVT any day, and hold more power and is 100% electronically controlled. basically its bullet proof from the factory. and ZF is one of the best transmission manufactures on the planet. You have no idea what your talking about..
how come when I drove a Nissan with a CVT it behaved like it had gears? under hard acceleration I expected it to stay at fairly high RPMs but instead it went up to redline then shifted down a lot then kept on rising to redline as if it had gears. from my driving experience I felt that I could have made the gearbox work much better for both speed and efficiency if i had manual control of the ratio.
Sport mode emulates shifting. So if you had the shifter in Ds, you will get the "shift"
Larommi71 You don't even need sport mode for that. The 4 cylinder Altima has a manual mode, but does not have the sport shift mode. You have to upgrade to the V6 model for that, and it's really just more aggressive ratio selection to keep the engine in its performance powerband rather than the usual fuel saving rules. In fact, you engage sport mode by moving the shifter into manual and then back into automatic.
Its not that the car slows down or the speed drops but, normally a car when it changes gears it pauses a second and does not go any faster threw the shifting which most people don't notice because it happens so quickly.
This is a propaganda film. I really hope people aren't fooled by this. The CVT was designed with one thing in mind: making a cheaper part while charging the customer more.
Nissan CVT = POS.
Explained.
I would think that because CVT's are always high on revs where the maximum torque is, the wear and tear is higher than in a vehicle that uses a double clutch gearbox or manual one. Other than that, efficiency wins in a CVT
I need a link to the song. Can't find on youtube
By watching this I better understand why CVTs Suck.
Amin Mohammadzadeh eres innombrable canijo y todo los gringos estan acostumbrados a los bigcars con big transmissions no lo crees loco
Nissan CVT's are the worst in terms of reliability and programming. No other manufacturer has as many complaints logged against them as Nissan has. JATCO is not reliable and Nissan has these transmission programmed to maximize fuel economy while making the car seem like it's 10 years old and falling apart with acceleration problems and lugging. Up hills the car sputters. Yeah, Nissan states this is NORMAL. I'll stick to planetary gear driven. Keep the CVT's in the hybrids where they belong.
A CVT works like a bike except the fact that instea dof shiftingk to a bigger gear to go fastes the whole roller that the belt is on gets bigger. When they use the manual mode it is just programmed tomake it "seem" like you are shifting by raising and lowering rpm and the roller thats the belt is rolling on. So they arent actually shifts. Youusually have to use the manual mode when you need to go higher speeds from a cruising speed of about 60 or so. hope that helps
Man those are some HARDCORE gear changes in the automatic.
This fails to explain that the Nissan CVT needs to be replaced every 40000 miles. Stay away from these transmissions.
LivesHacked 3 years factory warranty or 160000 KLM I won't pay at all
The worst Automatic transmissions ever made
I have 3.5 Altima Coupe.. I felt CVT is amazing. I don't like to drive AT anymore.
CVTs use hydraulic pressure to move the wheels. When you floor it, all does is keep spinning the pump and generating pressure. If you stop the pump or slow it down, the transmission puts on a halt. So, downhill it does slow it down a lot. But if you want to vehicle to keep going you have to have engine spin the pump. Therefor, there is no disconnect from the transmission ever unless you put it in neutral and in turn disconnect the pump from the axle. Smooth acceleration is true about these vehi
CVT sucks. End of Story.
👍
Is ok if you just want to move from point A to point B or if you are not an enthusiast.
Personally my favorite is manual transmission.
real men use three pedals wooooooh
CVT is theoretically the superior of any transmission to ever be invented, whether it be for fuel economy or acceleration. People just don't like it because it takes out an element of driver interaction. But, since they don't want to admit that, they like to say that it sucks because it isn't as durable as other transmissions, which is true, but still.... With some more research into making them more durable and cheaper, CVTs will objectively be the better transmission.
You don't know what you're talking about as long as you do your maintenance any transmission should have zero problems unless there is a defect cvt transmissions simply require a more regular service for them to operate correctly. I love going and shopping for a used car and asking people when the last time they had the transmission serviced.... generally the answer is "I don't know" aka "your supposed to do that?" Her dur dur
Passing a big rig on the right. Very dumb Nissan!
I like his shoes
whats the difference between it and my scooter's cvt? to me the automatic transmission just looks like it would last longer cuz of its planetary gears and hydraulic clutch system not wearing out as fast as the cvt belt.
Haha I too thought that
