The fuel efficiency of CVT transmissions has been demonstrated to increase, and they are often more dependable than standard automatic gears. The vast majority of vehicles equipped with CVT gears have reliability ratings that are on par with conventional vehicles. The reliability of the most recent technology is typically understood to be tied to the reliability of other components and to give constant dependability.
Although CVT transmissions are designed to require essentially no maintenance, numerous factors could interfere with their performance. Your CVT transmission may experience troubles if the car is out of alignment.

How durable are Toyota CVT transmissions?
The lifespan of a CVT transmission is the same as that of a conventional automatic transmission, and they are built to last the entire life of the car. The lifespan of a normal CVT is at least 100,000 kilometers. Some vehicles, like the Toyota Prius, frequently have a lifespan of far over 300,000 kilometers. Some brands, like other automotive parts, last longer than others when maintained properly.
Toyota CVT gearboxes are they dependable?
Although conventional and dual-clutch automatics are more common, CVTs are very smooth in urban environments and are favored by hybrid vehicle manufacturers like Toyota and Lexus.
Because of how they function, CVT gearboxes are typically quite trustworthy and provide exceptional fuel efficiency. They provide you immediate power when you want to start moving, but not everyone will enjoy the noise they generate when accelerating quickly. The best automobiles with CVT transmissions are currently for sale, if you can handle that.
How much time will the Corolla CVT last?
Anybody will tell you that a Toyota Corolla should have a 300,000-mile lifespan. Of course, that assumes excellent upkeep. If you don’t adhere to your maintenance schedule, change your oil and transmission fluid on a regular basis, and drive safely, you won’t make it there.
In a survey of still-running automobiles with more than 200,000 miles on the odometer conducted in 2020, Toyota makes up six out of ten of the top ten vehicles in terms of life expectancy. The Corolla may not have made the top ten merely because it has always been a reasonably priced, low-maintenance daily driver.
More than 16% of them have topped 200k because someone who drives a Land Cruiser is likely to put a lot of time and effort into keeping it operating. The Corolla, on the other hand, is a car you might gift to a nephew when they start college after using it for seven or eight years to commute to work.
Of course, if you hang onto your Corolla and give it the same loving care and attention you’d give a classic, you might hit 390,000, as one driver did in a 2006. Even so, you might defeat that. A 1991 Corolla with a million miles on it is displayed with pride at a dealership in Florida. Although the real distance is 939,037, it’s still quite close.
You can find Corolla owners boasting about their first 300k in any automotive forum. Not every Corolla will endure the journey.
The previous owner may have neglected maintenance, your vehicle may have a flaw you are unaware of, and there is always the possibility of a surprise collision just before the finish line.
The fact remains, though, that a Corolla reaching 300,000 miles with its original engine and transmission in tact is not at all unusual. That is twice what Consumer Reports lists as the industry average, if you’re keeping score.
How trustworthy are CVT transmissions?
Considering purchasing a CVT-equipped vehicle as your next vehicle? It depends on whether you want to operate a gear-driven vehicle or not.
Although continuously variable transmissions (CVT) are not a recent technology, it has only been in recent years that drivers have gotten increasingly accustomed to them.
The DAF 600 was first made by the modest Dutch company van Doorne Automobiel Fabriek (DAF) in 1958. Even though it was one of the first mass-produced vehicles using a CVT, the vehicle was a failure. Subaru released the Justy, a CVT-equipped vehicle, in 1987. However, it was also a market failure for a number of reasons, such as worries about CVT dependability and the noise they omit.
Despite their often unfavorable reputation, CVTs do have some benefits, including as significantly increasing an engine’s fuel efficiency when it accelerates and being said to be less expensive than current eight- and nine-speed automatic gearboxes.
What Is a CVT?
The majority of automatic transmissions run on gears. Conversely, CVTs don’t even have any gears. The alternate name for them is pulley transmission since they run on a system of movable pulleys connected by a belt.
Drivers began to accept CVTs after Japanese carmaker Nissan introduced its Murano SUV with one in 2003. These days, CVTs are an ubiquitous sight on our roadways. Nissan, for example, provides the CVT on a variety of its models, including the Murano, Altima, Maxima, Rogue, Sentra, and Versa. Additionally, some Jeep Compass and Patriot models, BMW Minis, Mercedes-Benz Class Bs, some Honda Civic Hybrids, Mitsubishi Lancers, and a few Toyota vehicles all come with CVTs. Both Chrysler and Ford offered CVT-equipped automobiles, but they changed course after a while because customers believed the reliability of CVTs was in question.
CVT Maintenance and Repair Advantages and Disadvantages
The reliability of CVTs is comparable to that of conventional automatic transmissions in most cases. However, it’s possible that their use is more appropriate for smaller cars than for larger ones.
However, proactive preventative maintenance on some CVT models may necessitate regular transmission fluid changes, especially when compared to conventional sealed automatic transmissions, which can function for up to 100,000 kilometers or more before requiring maintenance. The CVT’s biggest enemy is heat. As a result, certain oils are needed for certain transmissions.
Who is the owner of the worst CVT?
However, Nissan CVTs are also notorious for breaking down quickly, which is why several lawsuits have been filed against them. The transmissions have a bad reputation for trembling, making odd noises, overheating, and putting the car into “limp mode.” The CVTs made by Nissan, according to some, are the worst transmissions ever created.
Who manufactures Toyota’s CVT transmission?
Many Toyota cars come equipped with a series of continuously variable gearboxes (CVTs) known as the Toyota K CVT transmission. The Toyota Group of Companies company Aisin, a producer of vehicle parts, is responsible for making the transmissions. A CVT is a kind of automatic transmission that can switch between a wide range of gear ratios without jerking. Other transmissions, in comparison, only offer a finite number of gear ratios in predetermined increments. The two pulleys in the K series are connected by a belt.
Should I purchase a vehicle with a CVT?
When compared to a conventional automatic, a CVT may offer a smoother driving experience depending on the car and the driver. One of the biggest benefits of having a CVT, according to Carfax, is that they frequently use less fuel than a standard automatic.
Can a CVT handle a lengthy drive?
Numerous automobile manufacturers offer a continuously variable gearbox (CVT) as the default choice for a wide range of cars, trucks, vans, and SUVs. Although some passenger vehicles have had this technology since 1989, if you are used to driving an older car or your favored brand recently upgraded what you like to drive, it may be a new feature to you.
The power from the engine is then transferred to the wheels of the car when you utilize a regular non-CVT transmission. There are no gears at all with the constantly variable transmission. This design makes use of a belt-connected section of pulleys with different widths. The engine is connected to one of the pulleys, while the wheels are connected to the other.
The breadth of the pulleys varies according to the amount of power required for each movement. One will expand while the other contracts, permitting a powerful acceleration without hesitating. A number of rollers and discs are used by some CVT choices to accomplish a similar goal.
You should consider these advantages and disadvantages of a CVT transmission before taking a test drive in a car with this technology.
List of the Pros of a CVT Transmission
1. CVT transmissions increase a vehicle’s fuel efficiency.
The increase in fuel efficiency while driving is the continuously variable transmission’s most important benefit to drivers. The manufacturers and models that offer the CVT option typically obtain rankings that place the car at the top of its class or very close to it for the MPG you get. On average, mid-sized cars get close to 40 miles per gallon on the highway, and hybrids get nearly 50 MPG. When this technology is used, even trucks and SUVs commonly achieve MPG values exceeding 20.
2. CVT transmissions offer a quick response when driving uphill.
The continuously variable transmission will react quickly when you press the gas pedal all the way to the floor if you frequently drive up hills (such as while commuting up a mountain pass). This technology searches for the optimal ratio for the acceleration you need in order to provide the highest degree of power at all times. This means that, especially while handling a high load, you don’t need to worry about changing into a different gear or letting up on the gas pedal to help the transmission reset.
The reason for this benefit is the fact that the CVT transmission allows an endless number of gear ratios to use. You may easily reach a cruising speed with the help of this option, which enables you to handle a wide range of driving circumstances. It will always maintain the engine’s power range, which is ideal.
3. Over long distances, CVT gearboxes offer a more comfortable ride.
A continuously variable gearbox eliminates the jerking and hesitation that older technologies occasionally brought with them when you are driving. This function automatically adjusts to the needs of the vehicle at any given time, thus finding the right gear ratio to be in is not necessary. There are numerous accounts of transmissions bouncing and grinding that caused property damage or serious personal injuries because the device didn’t function as planned.
Your ride will be smoother if your car has a CVT transmission because of the pulley or rotor/disc technology that is used to make each essential shift. The technology is constantly altering, so you will feel more changes throughout the flight, although the subtlety of the process is typically not noticeable in the cabin.
4. There are fewer components in CVT transmissions that could degrade over time.
The vehicle’s shifting system is made simpler by the continuously variable gearbox, meaning there are less moving elements that could malfunction while the automobile is in use. This implies that your overall chance of encountering a failure while driving is decreased. Even if something were to go wrong with the system, this less complicated design could end up saving you money in the long term.
Even though certain models do require a complete system replacement, rebuilding a CVT is quicker when it is possible because you are not required to disassemble the entire set of gears in order to get the car running again.
5. Compared to conventional transmissions, CVTs are lighter.
A continuously variable transmission weighs far less than a conventional transmission since it doesn’t need a lot of gears to keep the right ratio while driving. Additionally, the product takes up less room overall underneath the car, which lowers the weight profile even more. As a result, your powertrain does not experience the same levels of stress that can cause premature wear-and-tear problems as you are driving down the road.
As a result of being able to maintain the proper gear ratio more frequently, this benefit can occasionally improve your fuel economy.
6. A superior torque ratio is provided by CVT gearboxes.
It is considerably easier for vehicles equipped with a CVT to identify and then maintain their appropriate torque ratio in every situation because the continuously variable gearbox does not require the same gearing as the previous technology. This means that you will have the ability to accelerate instantly from a complete stop, accelerate quickly when necessary, and maintain the appropriate ratio for a longer period of time as you drive.
For this reason, when ascending a mountain pass in a V8, you can find yourself getting passed by a little hatchback. The smaller vehicle climbs better as a result of its constant capacity to select the ideal gear ratio for any given situation.
7. With the right maintenance, CVT transmissions can last a very long time.
Pulleys used by this transmission in the early days of CVT technology occasionally broke. That implied that your operations expenses will very certainly increase. Although this problem has been resolved over the past few decades, most vehicles still require a complete replacement by the 100,000-mile milestone. Some owners have found that with regular maintenance and responsible driving practices, their transmission can last up to 200,000 miles (and occasionally longer) before it needs repair.
List of the Cons of a CVT Transmission
1. Replacing a CVT transmission can be very expensive.
Even while repairing a CVT transmission can be less expensive than repairing a conventional one, you’ll find that many automakers do not provide this alternative. Most drivers discover that when their unit breaks down, they are responsible for paying for a brand-new continuously variable transmission. You should anticipate having to replace it sometime between 60,000 and 100,000 miles because this option typically fails more quickly than what is on earlier vehicles.
Every year, a number of complaints about CVT transmissions wearing out before 50,000 miles are sent to several automakers, notably Subaru. To make sure you can exercise all of your rights, review your warranty with the vehicle. A full replacement should cost at least $3,000 and occasionally even more than $5,000. If you drive a Subaru, the price on some models may be closer to $8,000.
2. CVT transmissions will alter the way you drive.
Imagine you are on a two-lane highway and a slow driver is coming up behind you. If you are used to the conventional transmission, you may immediately gun it to pass the car without having to spend much time in the other lane. You need to drive carefully when your vehicle has a continuously variable transmission. Although some vehicles can accelerate and perform better, if you need an immediate adjustment in your driving conditions, you might also experience a delayed response.
As you approach the car you want to pass, you must plan the pass with an acceleration profile. Then, in order to ensure that you can make the pass in time, you must accelerate as you lose the draft. You might not be able to finish it in time if you don’t pick up the pace until after you pull out to pass.
3. The towing capacity of CVT transmissions is lower.
The process of towing with a continuously variable transmission is identical to that with a conventional transmission. Although the actual procedure is the same with this technology (which is a benefit), this choice typically includes vehicles that are designed to carry a little amount of weight. A car that has this option frequently has a maximum towing capacity of 1,000 pounds or less. If your engine is more powerful, you might get up to 3,000 pounds at a higher MSRP, but that is unusual because most CVTs are made to function best with 4-cylinder engines to get the maximum power out of them.
The same as you would with any other transmission, you can mount your receiver or hitch. The outlet might install the trailer for you if you are renting one to tow for a price. Then, unless you are driving on icy, snow-covered, or slick gravel roads, keep the CVT transmission in the drive position. With this choice, a certain gear ratio is not required to be locked. Make sure you never go above the allowed tow rating, too.
4. If a CVT transmission malfunctions, a total replacement is frequently necessary.
A rebuild is not possible for around 90% of the Subaru continuously variable gearboxes that need repair because of the way they malfunction. Usually, the damage is so severe that installing a new unit is the only method to restore the vehicle’s functionality. Although not often to the same an extent, this drawback applies to Nissan, Honda, and other automakers who utilise this technology.
Even when a rebuild is an option, you’ll find that the price of the repair can be 50% or even more than it would be to fix a conventional transmission. This indicates that the fuel savings you achieve with this technology do not ultimately pay for themselves by the time a replacement is required.
5. CVT transmissions occasionally become stuck at high RPM ranges.
You can use an endless number of gear ratios thanks to the technology of a continuously variable gearbox to increase performance. You’ll also learn that the CVT gearbox occasionally misinterprets the information it receives from the engine, causing it to believe that you must maintain a higher gear when you actually do not. This drawback will most frequently be felt when driving up an incline.
You can lose your current speed right away because the only method to reset the transmission is to let up on the gas. That necessitates you to step on the gas pedal once more, resulting in higher RPM levels that may hang you up once more. This problem can be really annoying if you’re climbing a steep mountain pass because it causes irregular speeds.
6. CVT gearboxes are significantly louder than conventional ones.
You’ll notice right away that a continuously variable transmission produces sounds that are significantly dissimilar from those you would hear from a conventional unit. Because driving today is so different from driving in the past, many drivers believe that their car is not running properly. Even on flat surfaces, there might be a lot of clunking, grinding, and even shaking from the vehicle. In some cars, adding your air conditioner to this process can exacerbate the problem.
Given that majority of the noises and vibrations originate from behind the seat, the driver is particularly bothered by them. Some models have the ability to produce droning noises that are louder than white noise. This issue will continue to be a drawback unless you get used to it.
7. The expense of routine maintenance is higher for CVT transmissions.
The cost of your routine maintenance will increase by the same amounts, just as you’ll spend 50% to 100% more trying to fix or replace a continuously variable transmission that breaks down. The price range for replacing the transmission fluid at the dealership is normally $250 to $350. If the pan and filter need to be updated as part of the servicing, it might even be higher. You must budget for this investment depending on what your manufacturer advises because you cannot delay your maintenance program owing to the hefty replacement expenses.
Working with a mechanic or independent service specialist to complete this task is an option if you don’t want to take your car to the dealership. In most cases, the costs are still much greater even then.
8. To minimize the possibility of damage, CVT transmissions demand safe driving practices.
You need to be cautious with your shifting techniques when driving a car with a continuously variable gearbox. The worst scenario is when you are backing up and immediately put the car into drive after shifting out of reverse before you have totally stopped your momentum. This behavior has no practical benefit and can be extremely difficult on the CVT. In order to lessen the strain on the structural integrity of your car, you should also apply the parking brake after shifting into park when you come to a halt.
