It is said that the CVT gearbox is easy to break, and it will be driven for 300,000 kilometers?

300,000 kilometers to drive. Because there is absolutely no problem with the CVT gearbox running 300,000 kilometers, and there are cars that have already run.

No problem for sure. Because the CVT gearbox has a stable quality, it can be driven up to 300,000 kilometers without any problems.

The CVT gearbox is not very easy to break, as long as regular maintenance, reasonable driving, and timely inspection, generally speaking, it can drive up to 300,000 kilometers

Open can. Because I have a car with a CVT gearbox, I have driven 250,000 kilometers myself, so there is no problem.

The Sylphy automatic transmission of 310,000 kilometers is still in normal use.

Generally, the life of an ordinary CVT gearbox will be about 400,000 kilometers. If there is no failure or accident, it can run up to 300,000 kilometers and can basically be used for 15 years.

The life of the CVT gearbox is about 5 years, and it cannot run 300,000 kilometers, so it needs regular maintenance.

It can run 300,000 kilometers. My car is a Tiida CVT gearbox that has been running for 330,000 km for ten years. Later, because I didn't upshift, I was able to go.

Start zero, but you can't upshift. Go fix it. Replace it with a remanufactured one and continue to use it.

If you take care of it better. I didn't change the transmission oil until I drove 150,000 km. If you change the oil every 40,000 or 100,000.

It is estimated that the service life will be longer. 300,000 should be available.

The life of CVT gearboxes is generally around 15 years. It can run 300,000 kilometers without failure.

I don't think about how long to run, the first new car A0-class sedan (MT) for three years, the second second-hand A-class SUV (AT) for a year, and the third new A-class sedan (CVT) is currently just over eight months, and I plan to try the garbage dual-clutch matching B-class sedan that I am not optimistic about in a few years, and all kinds of gearboxes have been handed over, isn't it very interesting!

CVT is the most garbage and cheapest gearbox, generally for motorcycles, and it is generally used on cars to cut corners to control costs.

The gearbox rang when the Camry started! The merchant said it was all like this! Have you ever met a friend? Is this normal?

Yes, the Honda CRV I drove is over 300,000 yuan, you can look at the car with me!

My byd, F is more than 310,000 years old, but the outward flow is not good, the tires are changed 4 times, the handling is smooth, and the power is very good.

Under normal circumstances, it does not go up to 3000 rpm for a long time, and occasionally high floor oil speeds will not have any effect on the gearbox and engine. But you have to do it for a long time, no matter what CVT, AT or dual-clutch or even MT and its engine damage is certain, which is also determined by the design of ordinary family cars

First, let's talk about the engine first, long-term high-speed rapid acceleration is abnormal for the engine.

Pressing on the throttle can quickly increase the amount of fuel injected, and insufficient combustion may lead to carbon deposits, and excessive rpm and frequent hard acceleration will also cause high engine temperatures and poor seal lubrication. This question is not alarmist.

Second, the gearbox also has the problem of high temperature caused by frequent rapid acceleration or long-term high speed.

The gearbox on a racing car generally has an oil radiator, which is basically not available in ordinary civilian cars. The normal use of free cooling can basically meet the heat dissipation needs of the gearbox. And the high temperatures caused by intense driving can be more direct to the transmission than the engine.

I drove a certain Ford dual-clutch model. The road is very congested, stop-and-go, plus more anxious, frequent rapid acceleration, overtaking and starting, when you walk to Taiping Road, there is a shaking situation when following the car at low speed. The CVT and AT are not as squeamish as the dual-clutch transmission, but they also suffer from overheating.

The CVT gearbox is also clearly marked with an overheating protection function.

Third, most of the cars or even a higher level of cars are basically family cars, not performance cars, and they are not very suitable for excessive and intense driving, and the risk factor also increases.

It's okay to do it once in a while, but it shouldn't be done often. Failure to do so will only increase the chance of failure and repair costs. If you're driving aggressively, use the S button to overtake at the right time, as it will slightly reduce the gearbox load and increase the rpm.

In short, the family car is a means of transportation until it has been completely modified, and it can be said that it is not the same thing as a performance car, a sports car, and a modified racing car.

No, this will not have too much impact and will not have a big problem with the service life, as long as the force is stable and continuous, it can achieve high frequency operation, because the quality of this gearbox is particularly good.

Of course it will be bad. Because the number of crimes has reached the limit of the gearbox, if this speed is maintained for a long time, then it will lead to transmission damage.

If it is at 3000 rpm for a long time, the gearbox will not have a rest time at all, and it will be scrapped slowly.

What if it's going to break and run at high speed? Does a high-speed gearbox break after a single run?

For a car, the gearbox of the three major parts can be said to be particularly important, and the quality of the three parts can be said to be a crucial one for the car, but many people say that the CVT gearbox is particularly easy to break, so how long is the life of the CVT gearbox that everyone knows? <>

In fact, the life of the manufacturer in the design of the CVT gearbox is very long, under normal circumstances, the life of the manufacturer design is about 300,000 kilometers or more, but in actual life may be far from being able to achieve such a number of kilometers, because many people in the car when driving, there are a lot of bad operations or a lot of operations that are very harmful to the car, so how many kilometers can be driven according to personal driving habits, under normal circumstances, the transmission ratio conversion between the steel belt and the pressure steel in the gearbox, In addition to these two reasons, the fuel tank of this gearbox is also related to the use of the entire gearbox, so according to normal driving habits, the gearbox can be used for about 200,000 kilometers should be no problem. <>

So if you are used to driving very violent acceleration or like to brake sharply, this will lead to a very high failure rate of this gearbox, and if you don't pay attention to maintenance, the number of kilometers may become less, in addition to this reason, that is, most of the gearboxes use a dual-clutch mode, and the dual-clutch mode will have a certain impact on the gearbox, and it may have a certain impact on the quality of the entire gearbox after driving fifty or sixty thousand kilometers, although it will not affect the continued driving. But this will directly affect the quality of the gearbox, so many people feel that this kind of gearbox is particularly easy to break, and it is very difficult to reach 300,000 kilometers completely, but it all depends on a person's habit of driving a car. If you judge it according to the habit of a normal family driving a car, it can reach about 200,000 kilometers at most, of course, this has a lot to do with the quality and configuration of the whole car. <>

Under normal circumstances, the CVT gearbox can be used for about 300,000 kilometers, and it can also prolong the life if it is properly maintained.

The Nissan Tiida in 08 is currently 270,000 kilometers, and the gearbox has not been repaired.

It can be driven up to 120,000 kilometers, and under normal circumstances, 6 to 100,000 kilometers need to be replaced, and the maximum limit is 120,000 kilometers, which is prone to problems.

Many people say that CVT is easy to wear, slip, unreliable quality, and has a short lifespan, but in fact, the core component of CVT is the steel belt inside, and its design service life has reached 300,000 kilometers.

Normally, a CVT gearbox can be used for 20 400,000 kilometers in the case of timely maintenance and gentle driving, and the family car can be used for 20 years in the case of 20,000 kilometers per year.

When analyzing a problem, I don't like to throw out a bunch of truths as soon as I come up, and I like to peel off the skin of an onion, peeling off those meaningless or confusing coats layer by layer, and looking directly at the essence of things.

X-Trail 4WD version, the same CVT, Subaru, the same CVT, how much torque do you want, now the maximum torque of CVT bears 350-450, how much torque your car has, normal in more than 200, in fact, not only my brother, there are also many people on the Internet who say that Japanese CVT cars have to overhaul the gearbox after 10 kilometers, and there are car owners who report that they have to change the gearbox after 1 year. There are also people who hold the opposite view, they believe that it is no problem to drive 400,000 kilometers with a CVT gearbox.

The mileage reaches 300,000 kilometers, at least it is already a car that has turned many times, and the vast majority of people see that the structure of CVT is driven by "belt", and there are indeed many CVT slippage incidents in the early years, so everyone thinks that CVT is easy to slip with false rumors. But this is not the case, most automatic transmissions will have all kinds of problems, not necessarily fatal, but are prolonged, this time is not bad is a blessing, and broken is duty. Have you ever seen CVT gearboxes scrapped in batches?

The shift is perfectly synchronized with the transmission, relying on pressure plates for CVT control belts and taper pulleys. It is the solenoid valve that controls the pressure plate. So be sure to make sure the oil is clean. Do not clog the solenoid valve. Then the steel belt should be less worn.

So as a user, what can be done is to ensure the durability of the gearbox has always been debated, the owner who has used the CVT gearbox has no problem will say, how good the CVT gearbox is, but the owner who has used tens of thousands of kilometers of damage will say that the CVT gearbox is not durable, and there will be problems for tens of thousands of kilometers. Infinite number of forward gears, which is why it is called "continuously variable transmission".

Personally, I think that CVT transmission oil needs to be changed.

Nowadays, many automatic transmissions are advertised under the slogan of maintenance-free, but is this really the case? Whether it's an AT or CVT gearbox, the transmission oil can't be truly maintenance-freeThe maintenance-free advertised by the manufacturer is only in the case of theory, or the conclusion of the test in the simulated road situation, everyone's driving habits are not the same, some people take the car as a treasure, some people use the car as a cow, and the load inside the transmission is also different.

Any oil has a service life, and during long-term use, the lubrication system of the transmission oil will be reduced, which will affect the sealing of the internal hydraulic components of the CVT transmission, and accelerate the wear between the CVT transmission steel belt and the pulley. This effect is not immediate, but only accumulated bit by bit in daily use, when you find that the uphill power transmission is insufficient, it is estimated that it will be 7-8 years later or about 300,000 kilometers.

Whether you change or not depends on how you drive

Therefore, whether or not to change the CVT has a lot to do with the individual's driving style. Frequent violent driving, big foot throttle, big foot brake, then the gearbox is too worn, there are a lot of impurities, frustration will be strengthened, after changing the clean CVT oil, less impurities will of course be smooth.

If it is a normal way of driving, there is little violent driving, and there is no need to worry about the oil quality at all. At least, driving to 100,000 kilometers is not a problem at all.

Therefore, everyone should judge their own driving style and decide whether they need to change the CVT transmission fluid.

Oil channels and oil change methods

In addition, there is another statement, but it has not been confirmed (only for Nissan models).

When the original car leaves the factory, there is a certain gap in quality between the added CVT oil and the CVT oil we see in the market, including 4S stores, and the quality of the original oil is better. Theoretically, there is such a problem, after all, the oil channel in the market cannot be guaranteed, even if it is a 4S store.

There are cases, after the owner replaces the CVT oil, the vehicle has a thermal protection phenomenon, most of the cases should be the oil channel problem, the quality of the replaced oil is not as good as the quality of the original car!

In addition, if you change the CVT fluid, it is best to use the traditional gravity oil change method and do not use the circulator. A waste of silver, at least two more barrels of gearbox; Second, the circulating machine allows the transmission oil to flow at high speed, which is easy to roll up the impurities of the oil pan and cover the entire gearbox, causing greater wear.

Don't look at the simple structure of the CVT gearbox, but it is still very delicate. At the very least, the difference between them is the distance of the steel belt from the gears, and the cost of later repairs is significantly higher than that of an AT gearbox. Therefore, it is better to drive as gently as possible, just as an "old man".

This is not true, any transmission oil needs to be changed, otherwise it will inevitably cause some damage to the car.

False, CVT transmission oil needs to be replaced, generally speaking, it needs to be replaced 1 time when driving 100,000 kilometers normally.

Not really. Because the gearbox actually has a service life, if it causes damage to the gearbox, it also needs to be replaced.
