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.

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.

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.

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.

Do not change the transmission oil of the crv
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.

The reason for the failure of the cvl transmission
The difference between cvl infinitely variable transmission and automatic transmission
There were the following differences between a CVS continuously variable transmission and an automatic transmission (here, automatic transmission refers to other types of automatic transmissions other than CVs, such as AT, etc.): 1. ** Transmission structure ** - CVs mainly used steel belts or chains (for example, some models used steel transmission belts) for power transmission. The oil pressure controlled the tightening and loosening of the driving wheel and driven wheel, and changed the working diameter of the belt wheel cone and the transmission belt (one wheel diameter increased, the other wheel diameter decreased) to achieve speed change. - The other types of automatic gears (such as AT) used a gear set to change the speed. It was through different gears to achieve power transmission and shifting. 2. ** Power transmission characteristics ** - Due to the continuous variable transmission method such as the steel belt, the CVS could continuously obtain any transmission ratio within the transmission range. The power transmission was continuous and smooth, and there was basically no sense of frustration during driving. - Automatic transmission (such as AT) was a computer controlled hydraulic transmission. There was energy loss, and sometimes it was obvious when shifting gears. 3. ** In terms of economy ** - The fuel economy of CVs was relatively high, and it was more fuel-efficient than some automatic transmissions (such as ATs). 4. ** In terms of power ** - The power performance of CVs was obviously better than some automatic transmissions (such as AT). 5. ** In terms of cost ** - The CVS system had a simple structure and low cost. Automatic transmissions such as the AT were relatively expensive. 6. ** In terms of discharge ** - CVs could reduce the amount of exhaust gas and had certain advantages in terms of environmental protection.

How to distinguish between cvl and at transmission
Distinguishing between CVs and AT transmissions can be done from the following aspects: 1. ** Shifting experience **: - The CTV did not have a real gear, and it could change the distance at any time and place. It was very smooth when driving, and there would be no feeling of shifting gears. When the fuel was evenly supplied to start accelerating, the speedometer pointer would slowly increase or maintain a speed. - The AT had a real gear shift, and the gear shift action was a few points. When the fuel was evenly supplied, the speed increased, then decreased, and then increased again. There was an obvious upshift action. 2. ** Torsion Resistance **: - CVs couldn't withstand large torques, and once they were large, they would slip, so they were commonly used in small displacement models or large displacement self-suction models. - The AT could withstand a large amount of power and could be matched with a powerful engine, which was suitable for violent driving. 3. ** fuel economy **: - The fuel economy of CVs was better. Under the same displacement engine, the fuel consumption of models equipped with CVs was lower than that of models equipped with AT transmissions. - The fuel consumption of the AT transmission was relatively high. 4. ** Cost **: - The manufacturing cost of CVs was lower, and the price and maintenance of vehicles were slightly lower than that of AT transmissions. - The cost of AT transmissions was relatively high, and the maintenance price was also relatively high. Many high-gear AT transmissions were even more expensive to repair than engines. 5. ** Principle of structure **: - CVs used a drive belt and a driving and driven wheel with a variable working diameter to transmit power. Like a correction belt, there were steel belts and cone wheels rotating inside to achieve continuous changes in the transmission ratio. - The AT mainly used a hydraulic torque-changer in combination with a traditional mechanical gear box (such as a planetary gear set) to achieve the gear shift function.

The cvl transmission starts with a creaking sound
The reason why the CVS transmission started to rattle could be due to the following reasons: 1. The abnormal sound made by the vehicle when it started was generally a fault of the suspension system, which may be caused by the loosening or damage of the engine support. In this case, the engine support needed to be replaced. 2. It may be caused by the damage of the internal valve body, but due to the stubborn dirt and impurities inside, especially the accumulation of dirt and impurities inside the valve body, resulting in the inability to effectively adjust the oil pressure, resulting in collisions, collisions, and slipping. In this case, the internal valve body needs to be replaced. 3. The wear and tear of the internal bearings of the transmission can also cause the CVS transmission to make strange sounds. At this time, the internal bearings of the transmission need to be replaced. 4. When the inner circle comes into contact with the journal of the main pressure cylinder, it is easy to wear and loose. There are many pockmarks on the journal, resulting in abnormal sounds. In this case, it is recommended to go to a 4S shop or repair shop for maintenance.
