The CVT is an automatic transmission that runs a steel belt between two pulleys. The diameter of the “drive pulley,” which transmits torque from the engine, and the “driven pulley,” which transmits torque to the wheels, are simultaneously adjusted by the CVT to continuously modify its gear ratios.

Nissan CVT transmissions: Are they dependable? Customers Suggest Otherwise!
The continuously variable transmission (CVT), an automatic transmission that uses computer software to control the ratio of gears chosen for the optimal driving experience, was invented by Nissan and is frequently credited as its inventor. The firm started working on its CVT in 1992, but didn’t start using it on a regular basis until around 2003. Nissan’s CVT transmission is merely impeding the company’s potential to expand and advance, even though the CVT is a brilliant milestone in the optimization of modern automobiles.
Nissan customers are unable to benefit from the device’s ongoing improvements since they are constantly need to deal with the CVT’s negative impacts, despite its numerous advancements. Due to their endurance and durability—which they attribute to their reduced exposure to heat and friction—the business notes that CVTs are more reliable. Nissan’s confidence in the dependability of its CVTs has, unfortunately for many customers, been disproved by this component’s flaws, which have subjected them to higher temperatures and friction than they were intended to withstand.
The Way a CVT Operates
Since the driver is not required to physically engage the clutch or shift between the forward speeds, a CVT is technically an automatic gearbox. However, there are important distinctions between the two in terms of both form and function.
A CVT does not have a predetermined number of preset gears like a standard automatic (or manual transmission, for that matter). Instead, it employs an infinite number of gear ratios to take into account the driving habits and environmental factors at any particular time. A CVT transmission is frequently referred to as “single-speed” or “shiftless” since it enables smooth shifts without any hard shift points.
A CVT uses two opposed cone-shaped pulleys with a chain or belt running between them to accomplish this unlimited gear ratio flexibility. This arrangement is quite comparable to how a chain moves over a bicycle’s gears.
The driveshaft and drive wheels get power from one cone, which is connected to the engine’s output shaft. The chain or belt moves up and down the sides of the two cones as a result of changing gear ratios as the pulleys move closer and farther away. Depending on the amount of power required, this movement changes the diameter of the chain or belt, which changes the gear ratio. While the car is moving, these continuous real-time alterations take place.
Nissan CVT: What is it?
Continuously Variable Transmission, also known as CVT, is a Nissan-invented auto transmission technology. Nissan has been incorporating it into some of its vehicles for more than 20 years because, when compared to conventional transmissions, it offers superior power distribution and outstanding fuel economy.
The seamless nature of gear shifting in a CVT-equipped car is one of the most obvious features for drivers to notice. The vehicle behaves as though it has a variable gear for every driving circumstance that is encountered, therefore shift shocks are gone.
constantly changing transmission
An automated transmission that can vary smoothly across a continuous range of gear ratios is known as a continuously variable transmission (CVT). Other transmissions, in comparison, only offer a finite number of gear ratios in predetermined increments. With the right control, a CVT’s flexibility may enable the engine to run continuously at a set RPM even while the vehicle’s speed changes.
SERPRESULT
Traditional automatic gearboxes contain gears that act as “steps” between low- and high-speed operation; CVTs don’t.
Since the early 2000s, Nissan has used continuously variable gearboxes (CVTs) in the majority of their vehicles.
A continuously variable transmission: is it beneficial?
Since they have been a common type of transmission for many years, CVTs are widely regarded as dependable. Because they offer outstanding fuel efficiency and smooth, consistent power delivery, they are particularly well-liked in hybrids and SUVs.
Is an automatic and a continuously variable transmission the same thing?
Continuously Variable Transmission (CVT): Although a CVT is constructed very differently from a typical automatic transmission, it functions similarly to one. A CVT uses no gears whatsoever.
Nissan CVT transmission issues, what year?
Let’s start by discussing the CVT overview. Continuously Variable Transmission is what it stands for. Once activated, it operates similarly to a conventional automatic transmission, requiring no further intervention from the driver. But the CVT has no gears. It operates with a dual pulley system. A smoother transition between lower and higher speeds as well as improved fuel efficiency are the goals of this more recent transmission. Although this makes sense in theory, there have been some issues with Nissan applications. The problems were typically reported between 2012/2013 and 2018. When Nissan first started utilizing this transmission in 2003 and during the generation of CVTs from 2007 to 2012, there were a few issues. The Murano, Sentra, Altima, Rogue, Versa, and Versa Note are specific models.
Although anything might go wrong for any manufacturer, Nissan’s issue is most likely the result of overheating. Failure to adequately cool the transmission might hasten the deterioration of the transmission. Additionally, for these specific models, the automobile detects heat distress and lowers its RPMs to prevent damage, which naturally affects horsepower. Nissan’s extended warranty may be useful for a while if your vehicle is affected and/or recalled. Transmission coverage was extended for some vehicles from 5 years/60,000 miles to 10 years/120,000 miles. Nevertheless, the warranty will eventually expire, and you might discover that your car needs, which
How frequently should the fluid in a Nissan CVT transmission be changed?
How frequently does my Nissan need to exchange the CVT fluid? Around every 30,000 miles, Chapman Nissan advises changing the continuously variable gearbox fluid.
Nissan still use CVT gearboxes, right?
Current Nissan models with XTRONIC CVT include: The XTRONIC CVT, which is offered throughout the entire Nissan portfolio, is the automatic transmission of the future. Nissan offers XTRONIC CVT(r) on the majority of its models, including SUVs like the Murano and Rogue.
Does Nissan offer free transmission repairs?
You will need to decide where to transport your vehicle if it is subject to an active recall. Even if a Nissan shop would repair your automobile for free, not all of them may have the necessary tools. Dealership service centers are frequently occupied since they are designed for buying and selling automobiles. This can make setting up a recall appointment very difficult.
Nissan CVT transmissions have a mileage cap.
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.
Nissan CVT transmission failures have a cause.
Nissan CVTs are notorious for overheating, especially while going up a steep incline or for an extended period of time at highway speeds. The transmission frequently enters a fail-safe or “limp” mode when it overheats, which results in a lack of power.
Is CVT superior than automatic transmission?
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. They are becoming a more common option for automakers in numerous vehicles in part because of this.
Can a CVT transmission be manually shifted?
The internal crankshaft of an engine spins at a certain rate, measured in revolutions per minute, or rpm, and this rate is converted to the necessary road speed via a transmission. Lower gears are used to provide the acceleration power, and higher ratios are used to sustain highway speeds with a lower engine speed for improved fuel efficiency.
When using a manual transmission, the driver depresses the clutch to briefly disengage the engine’s shaft and prevent the engine from transmitting power to the wheels, and then shifts into a different gear using the gear shifter. With an automatic transmission, sensors use planetary gear sets and a torque converter in place of a clutch to identify the proper ratio by taking into account the engine speed, vehicle speed, and use of the brake and throttle. Some vehicles offer “manual mode,” which allows the driver to change gears manually without a clutch using the shift lever or paddles on the steering wheel. Fourth to fifth is an example of how this cannot be done; fourth to sixth is. Most will override the driver’s option if the selected gear is too low or high.
Which automobile has the finest CVT?
Having said that, not all CVTs are made equal; some are superior to others. These vehicles all feature CVTs.
Honda (Jazz, City, CR-V, Civic, HR-V, Odyssey), Subaru (Forester, WRX), and Toyota make some of the greatest CVT-type automatics we’ve tested so far (C-HR, Corolla Altis, Vios, Yaris).
Due in significant part to the use of a torque converter to transfer power to the driving wheels, the CVT-type automatic transmission that is installed in these cars offers quiet operation and smooth acceleration.
However, the CVT installed in the Subaru WRX is the one that has so far shocked us the most. You wouldn’t be aware that the car has a CVT transmission if we hadn’t told you.
Contrary to other CVTs we’ve experienced, the Subaru WRX launches itself with great vigor when asked for more, and the CVT matches the shifting characteristics of conventional automatics, increasing the whole experience.
Then there is Proton, which continues to insist on equipping its vehicles with CVTs that have a start-up clutch.
Punch-sourced CVT-style automatic transmissions are installed in Proton vehicles such the Exora, Iriz, and Persona.
Although it may appear positive on paper, Proton cars with CVTs are jerky in traffic, loud, and unrefined—all things that a CVT is not supposed to be.
At least Hyundai-sourced 4-speed torque converter automatic has been installed in place of the Saga’s CVT by Proton.
To be honest, Mitsubishi’s application of CVT in models like the Outlander and ASX may best be regarded as average, as it is frequently hesitant when the pedal is pressed all the way to the floor and is far from being as responsive as its competitors. At motorway speeds, the noise level is likewise fairly loud.

What drawbacks exist with CVT transmissions?
As a relatively new product on the market, CVTs can be highly challenging to diagnose and repair. Even though CVTs are a newer technology and are simpler in design and have fewer moving parts, our specialists are well suited to operate on your car because they have undergone comprehensive training specifically for CVTs.
The following are some CVT issues to watch out for:
- Transmission “jerking,” “slipping,” “grinding,” or “jumping” while the car is accelerating and changing gears
- Some consumers complain of a “whining,” “clanging,” or “rattling” sound while driving, particularly with Nissan CVTs.
- Low or contaminated transmission fluid
- Overheating
- Engine Check Light On
- Changing gears at a high RPM
