The cvl transmission buzzed after changing the oil
If the CVS transmission hums after changing the oil, there may be the following reasons: 1. ** Wrong oil change **: The oil of the automatic transmission and the oil of the continuously variable transmission cannot be used together. If the oil of the automatic transmission is accidentally used in the CTV transmission, it may cause damage to the transmission in a short period of time, resulting in a buzzing sound. Because the transmission structure of the CTV transmission is a belt wheel instead of a gear, it is easy to cause damage if the oil is used incorrectly. 2. ** Use fake oil **: Once inferior transmission oil is used, not only will it not be effective in terms of smoothness and cleaning, but it will also form coke inside the transmission, which cannot be cleaned at all. This may also cause buzzing, and subsequent maintenance is troublesome and expensive. It may even cause the entire transmission to be scrapped. 3. ** Metal debris blocking the valve body **: When the CVS transmission works, it relies on the friction transmission of the steel belt on the cone wheel. If the oil change period is too long, it is easy to produce metal debris, which will block the transmission valve body. It may cause buzzing sound, pause, or even directly run into neutral or break down. Although it is recommended to change the oil according to the actual road conditions in China for 60,000 - 80,000 kilometers, if the oil change period is too long before, it may cause some damage and buzz even after the oil change.

After changing the transmission oil, the car buzzed
After changing the transmission oil, the car might buzz for the following reasons: 1. Normal running-in period: There is a running-in period when the new transmission oil has just been replaced. In this case, the owner does not need to worry too much. After the running-in period, the abnormal sound will usually disappear. 2. Transmission gear problem: - Too much gear clearance: When the driving gear is rotating, it will collide with the driven gear, causing a collision sound. When the vehicle is driving, the temperature of the transmission will rise, and the abnormal sound will increase. - If the gear gap is too small, it will cause continuous abnormal sounds. The sound is sometimes uniform and sometimes chaotic. The faster the speed is, the louder the abnormal sound will be. It will also cause the transmission oil to be overheated. 3. "Other possibilities: The parts in the transmission were damaged due to excessive wear. In this case, the car needs to be driven to a 4S shop for inspection."

The transmission is loud after changing the oil
The loud noise after changing the transmission oil was probably because the new transmission oil was too viscous. When changing the transmission oil, you should check the maintenance manual and purchase the transmission oil according to the specifications required in the manual. In addition, there were the following reasons for the wear and tear of the transmission after the oil change: 1. The transmission made a sound of dry metal friction. It might be due to lack of oil or poor oil quality. It should be refilled and the quality of the oil should be checked. If necessary, it should be replaced. 2. If the noise is obvious when changing into a gear while driving, it means that the gear teeth are worn; if there is a periodic noise, it means that individual teeth are damaged. 3. It sounded when the gear was in neutral, but the noise disappeared when the clutch pedal was stepped on. Generally, it was the front and rear bearings of a certain shaft or the constantly engaged ring gear. It would ring when any gear was changed, and most of them were the rear bearings of the second shaft. The novel " Watching the Moon on Fish Island " is equally exciting.

How often do you change the cvl transmission oil?
The oil in the Nissan-made CTV transmission was changed every 40,000 - 60,000 kilometers. In some special cases, the oil change period was different. If it is a hybrid CTV transmission from Japan, it is recommended to replace it once every 50,000 kilometers; if the road conditions are bad, it can be replaced once every 60,000 to 80,000 kilometers; it is also recommended to be replaced after 25,000 - 30,000 kilometers; it is not recommended to replace it after more than 100,000 kilometers. In addition, if the quality of the CVS transmission oil is poor after inspection, it should be replaced if it turns black, smells bad, has colloid, iron filings, etc. During the driving process, if there is a lack of acceleration, gear shifting, and other situations, it is also necessary to consider changing the transmission oil.

Loud noise after changing the transmission oil
The noise after changing the transmission oil may be caused by the following reasons: First, the new transmission oil's stickiness is too low; Second, if the transmission makes a sound of metal dry friction, it may be due to lack of oil or poor oil quality. You should refuel and check the quality of the oil, and replace it again if necessary; Third, if the noise is obvious when changing into a gear during driving, it may be the gear teeth of the gear are worn out. If there is a periodic noise, it may be the damage of individual teeth. Fourth, when the neutral gear sounds, but when the clutch pedal is stepped on, the noise disappears. Generally, it is a problem with the front and rear bearings of a certain shaft or the constant engagement ring gear. It will sound when changing any gear, mostly the rear bearing of the second shaft will sound. When changing the transmission oil, the transmission oil should be purchased according to the specifications required for the vehicle transmission in the maintenance manual.

How long does it take to change the nirvana cvl transmission oil?
The oil in the Nissan-made CTV transmission needs to be changed every 40,000 - 60,000 kilometers. However, if the quality of the CVS transmission oil is poor after inspection, black, smelly, colloid, iron filings, etc., it must be replaced. There will be slight differences between each model, but it is recommended not to replace more than 100,000 kilometers. If it was a hybrid CTV transmission from Japan, it was recommended to replace it once every 50,000 kilometers. If the road conditions were bad, it could be replaced once every 60,000 to 80,000 kilometers in advance. The novel " Watching the Moon on Fish Island " is equally exciting.

Life of cvl transmission
The design life of the CVS transmission was about 250,000 - 300,000 kilometers. However, in actual driving, due to the different conditions of the owner (such as driving habits, vehicle maintenance, etc.), their lifespan would also be different. Under the condition of good vehicle conditions, less intense driving conditions, and timely maintenance, its actual driving life could reach 400,000 kilometers. However, due to manufacturing errors, not all CVs could meet the design standards. However, within a certain probability range, CVs could run more than 300,000 kilometers. However, in general, the structural characteristics of CVs were relatively fragile, and their reliability in the power transmission process was not as good as that of AT, DV, and MT transmissions.

How often do you change the oil in the cvl infinitely variable transmission?
The replacement cycle of CVS continuously variable transmission oil varies due to many factors. Generally speaking, the theoretical oil change cycle was 100,000 kilometers. If it was a hybrid CTV transmission from Japan, it was recommended to change it once every 50,000 kilometers. If the road conditions were bad, it could be changed once every 60,000 - 80,000 kilometers in advance. High-grade CVs (such as the ones produced by Japan) could, under ideal conditions, change the special oil every 200,000 kilometers (based on computer tests). The CVs that accelerated at maximum speeds all day (such as racing on the track all day) had to be replaced every 30,000 to 40,000 kilometers. In addition, the specific oil change and maintenance period of each model still needs the owner to consult the vehicle manual by himself. The owner can also adjust the oil change period according to the actual vehicle working conditions. If the vehicle working conditions are bad, the oil change range/period should be shortened; otherwise, it can be extended. The novel "Watching the Moon on Fish Island" is equally exciting.

The working principle of the cvl transmission
The CVS transmission was mainly composed of two variable diameter rollers (shaped like a pair of cones) and a steel belt or chain. One of the rollers was connected to the engine (power input) and the other was connected to the drive shaft (power output). During operation, the transmission ratio was changed by changing the diameter of the rollers (that is, the contact diameter between the cone and the steel belt or chain). For example, when driving at a low speed, the diameter of the input end of the wheel was smaller and the speed was higher, while the diameter of the output end of the wheel was larger and the speed was lower. As the speed of the car increased, the diameter of the two wheels changed, causing the speed of the output end of the wheel to increase. According to the different power transmitting devices, it could be divided into steel belt CVs and chain CVs. When the steel-belt CVS works, the driving cone wheel presses the side of the steel belt formed by the overlapping of the metal sheets and the metal rings to form static friction force, and the hardness between the push sheet materials is used to form thrust force, so that the steel belt drives the driven cone wheel to rotate to transmit power. When the driving wheel is clamped to the middle by the oil pressure device, the steel belt moves upward along the side wall, the circumference of the driving wheel increases, and the circumference of the driven wheel decreases, thus realizing the amplification of the engine's torque-force. The chain of the chain-type CVS was composed of a ring-shaped steel sheet and a pull piece. When it worked, the chain did not directly contact the cone wheel, but the middle rocking arm pin was pressed to achieve the transmission of the moment.

The cvl transmission slammed on the accelerator
There may be the following reasons for the CTV transmission to slam on the accelerator: 1. The internal friction plate of the transmission was faulty. In this case, he needed to go to the 4S shop for maintenance. 2. The problem with the transmission oil could be solved by changing the oil. 3. If the oil pump fails, if the damage is not serious, you can apply soap on the damaged part, separate the damaged pump membrane from the intact pump membrane, stagger the damaged part, and then re-install it; if the damage is serious, it needs to be replaced. 4. When stepping on the accelerator, the inertia of the internal operating components of the engine caused an impact. This was a normal phenomenon and did not need to be solved. However, stepping on the accelerator itself did not conform to the working characteristics of the CVS and should be avoided as much as possible. 5. The corresponding speed of the transmission was not fast enough, and the speed of the upshift could not keep up with the speed of stepping on the accelerator, so there would be a sense of frustration when shifting gears. The solution was to step on the accelerator slowly. 6. With the intervention of the energy recovery system, once the driver released the accelerator pedal or stepped on the brake pedal, the generator would immediately start to work, putting some burden on the engine, affecting the engine speed, causing the engine speed to be out of sync with the clutch plate speed. This would cause a feeling of stagnation and need to go to the repair shop for repair. 7. If the grease is insufficient, new engine oil can be added. 8. For the Japanese CTV, the oil circuit of the electromagnetic valve was not smooth, and the movement of the valve core cutting the magnetic induction line was hindered, resulting in the insensitivity of the oil pressure adjustment and the occurrence of a setback. This was because the friction between the steel belt and the wheel shaft produced fine metal wear debris. Although it was attracted by the magnet, it could still block the oil hole and the filter core of the electromagnetic valve, causing the oil hole of the valve body to be blocked. The movement of the valve core was not smooth, and the pressure applied to the steel belt was not precise enough, causing the steel belt to slip and cause a setback.
