Nissan CVT Transmission Problems and How to Fix Them– Nissan technology is indisputable.nissantakes everything related to its four-wheel products very seriously. In addition to the constantly evolving internal combustion engine, other parts, such as the powertrain, are also constantly being supplemented and updated. All to improve vehicle performance efficiency amid the widespread problem of power outages. In terms of the transmission system, Nissan used a CVT transmission system. In this article, we discuss the CVT transmission, its problems, and how to deal with them.
CVT transmission vs. automatic transmission
The gearbox is a very important part of the drive system. Engine speed goes directly to the gearbox via the input shaft. From here begins the mastery of the great energy of the machine.
In the early days of four-wheelers, the car's steering system still used a manual transmission. Not just Nissan, but other car manufacturers around the world. So we developed what we call automatic transmissions. This transmission is based on a hydraulic clutch called a torque converter. No more clutch pedal for automatic transmissions.
Fuel efficiency requirements are forcing manufacturers to think about the energy consumption of their products. Here the automatic transmission changes to a CVT transmission. And Nissan is the one who developed the technology.
Cars have a system in the engine that is commonly known as a gearbox. The transmission in the car is divided into two types, namely automatic transmission and manual transmission. Although many people have switched to automatic transmission cars, some people are still interested in manual transmission cars.
Because a manual transmission still has advantages that an automatic transmission doesn't. One of the advantages is the possibility of adjusting the speed according to the wishes of the driver. Manual transmission cars are also more powerful than automatic transmissions. Therefore, some people still keep their vehicles with this transmission.
Before that, you need to understand the basics of this manual transfer. This is for you when you have car gearbox problems so you can overcome them. The manual transmission is a component of the engine and is used to transmit the speed and power of the engine to the moving wheels.
This power transmission system consists of several components, namely the differential clutch, transmission, wheels, and axle of the vehicle. Some of these components are interrelated and connected like the driving force of the car. On manual transmissions, the location and components are at the front after the clutch.
With this gearbox, the power generated comes from the engine, which is sent to the driveshaft to allow the car to move. Thus, the meaning of manual transmission is summarized, that is, the components that transmit the power generated in the engine to the axis of the wheel, which is in motion or rotating at a certain speed.

An automatic transmission, sometimes spelled A/T, is a type of transmission system that allows automatic gear changes. The change occurs according to the pressure on the accelerator pedal. This differs from the manual transmission system, which requires both the clutch pedal and the shift lever to change gear.
With a manual transmission, the driver must depress the clutch pedal and move the lever to change gear. The coordination of movement must be precise, otherwise the car dies. Unlike an automatic transmission, you simply shift the gear stick without first having to depress the clutch pedal. Both automatic and manual transmissions can also be found on the machine.
How does the automatic transmission work? The operation of the automatic transmission is more complicated than that of the manual transmission. This is because the automatic transmission has several components that the manual transmission does not. The relevant components are the torque converter (torque or torque converter), the hydraulic control unit and the planetary gear.
All three of these components can be found in transmission oil. With these three components, the function of transmission oil is very different. Oil not only serves as a lubricant and coolant, but also as a gear lever. This entire arrangement was called automatic transmission fluid (ATF).

The use of continuously variable transmissions (CVT) in new cars is becoming more and more popular. However, there are definitely still plenty of people who are just fumbling around or don't even know what a CVT is in a car. This includes how it works, the advantages and disadvantages of the CVT over regular automatic transmissions.
Essentially, a CVT is a type of automatic transmission that uses a steel belt and two pulleys as a ratio controller. The diameter of each pulley can be smaller or larger.
The concept is very different from traditional automatic transmission systems that use multiple gears to define the gear ratio.
Although many manufacturers now refer to the CVT as an advantage of their new car, the CVT itself is actually a technology that has been around for a long time. Even the concept has been found since the 1870s.
Summarized from the free encyclopedia Wikipedia, in 1879 Milton Reeves, a pioneer in the US automobile industry, invented the CVT, then known as the variable speed transmission.
Reeves first used the invention on a lumber sawing machine. But that same year, Reeves also began installing CVTs in cars and a variety of industrial machines.
As is known, the CVT can also be used on motorcycles equipped with an automatic transmission. History records that in 1911 the Zenith Gradua 6HP was one of the pioneers in the use of CVTs in motorized two-wheelers. To learn more about CVT, please read;Learn more about CVT transmissions.
Nissan CVT Transmission Problems and How to Fix Them
In fact, Nissan has been using CVT transmissions since the 1990s. At the time, it was still rare for other automakers to use the gearbox. Most of them still use a multi-speed manual transmission and some use an automatic transmission. It wasn't until a few years before the 2000s that many manufacturers began to switch to CVT transmissions.
Nissan CVT Transmission
The first car to be equipped with a Nissan CVT transmission was the Nissan March, or Micra in some markets. The Nissan March or Micra was launched in 1992. At first, Nissan was reluctant to increase the use of CVT in its other models, which is only natural because other manufacturers have not used this type of transmission. But eventually they saw the potential. Finally, in 2002, Nissan first introduced the Murano SUV with a CVT transmission. This happened in the United States.
Since the Nissan Murano, the Japanese manufacturer has continuously improved and upgraded its "XTRONIC" CVT. Since then, it has been incorporated into most of Nissan's core products. This includes the aforementioned Altima, Juke, Maxima, Pathfinder, Murano, Qashqai, Rogue, Sentra, X-Trail, and more. Infiniti, Nissan's high-end brand (like Lexus Toyota), also adopted Nissan's CVT transmission.
Some non-CVT equipped models include performance cars like the GT-R and Fairlady 370Z. Recently, Nissan has withdrawn from the use of CVT transmissions. The new 2022 Nissan Pathfinder switched to a regular automatic transmission.
For more information, see;CVT "XTRONIC".
Nissan CVT Transmission Problems
Problems with the Nissan CVT can be identified by the traces of damage. There are some very clear signs that your car's Nissan CVT transmission is about to fail. The design of the CVT transmission is different from the common automatic transmission, so we can easily identify the problem. So first of all, let's take a look at the signs of CVT failure.
DIFFICULTY IN ACCELERATION AND WEAK RESPONSE
When driving, pay attention to how the car reacts to your actions when accelerating. Does the car pull nice and even or does it stutter? If it's hard to accelerate, it could be a sign that your CVT transmission is at fault.
These symptoms can be dangerous while driving. For example, you cannot quickly increase your speed when passing, following, or crossing intersections. The discrepancy between the speed of your car and the relative speed of the traffic around you can lead to accidents.
One of the shortcomings of Nissan's CVT transmission is the cooling solution. Experts say its cooling design is inadequate, possibly leading to overheating. This excessive heat causes certain mounts and bearings to wear more quickly, leading to the vibration or shock you feel when pedaling.
TRANSMISSION RUNS VERY HOT
Again, this has to do with Nissan's poor CVT transmission cooling system. You can easily recognize it by excessive heat inside the cabin or the smell of burning.
When parts of a car, such as the engine or transmission, overheat, a fail-safe mode usually kicks in. This is also known as "Limphouse" mode, in which the car limits speed and component operation. This is done to prevent further damage.
TRANSMISSION WILL BE DIFFICULT
By design, CVTs are usually noisier than regular transmissions. You can hear it during operation, although it is usually very faint. However, when your CVT fails, the noise becomes much more noticeable. If you hear a whine or rattle, your car's CVT transmission may need to be checked.
Again, this is related to the tendency of Nissan's CVT transmission to get hot. Overheating the transmission wears out parts of the surrounding cooling system, such as coolant lines or hoses. If you see standing water under the car, it could be coolant.
SHUTDOWN WITHOUT NOTICE
Another obvious sign of transmission failure is if the car breaks down or stalls while driving. Or maybe switch to Limp House mode. This, in turn, is another danger when driving. Imagine that the car stopped while driving on the highway at high speed.
how did i correct it
So how to solve problems with the Nissan CVT transmission? In a physically damaged condition, I don't think you can do the repair yourself. Unless you are familiar with Nissan CVTs, are a hobbyist, and of course have a lot of free time. Fixing the Nissan CVT transmission problem is quite complicated. It is necessary to remove the gearbox from the engine, disassemble it with special service tools and, of course, other equipment.
If you don't have everything mentioned above, going to a garage is the best solution. Choose a repair shop that has a good reputation for handling this problem. Some people suggest that if a Nissan CVT is bad, replace it with a straight assembly.
But of course there are ways to keep your Nissan CVT in good condition. The following tips can be a springboard for you.
1. Change Nissan CVT transmission oil regularly. Change the oil with oil recommended by Nissan and make sure that it is sufficient at all times.
2. If there is even a small oil leak, fix it immediately or take it to a repair shop.
3. Don't make the mistake of using a Nissan CVT transmission too often. Mistakes in the use of the gearbox can speed up the life of the gearbox.
