If you regret changing the transmission oil after six years, it may be due to the following reasons: ** 1. Problems related to the replacement operation ** 1. ** Oil does not match ** - If the new transmission oil does not match the original requirements of the vehicle, it may affect the normal operation of the transmission. Different vehicle models and different transmission types had specific requirements for oil. For example, some vehicles needed automatic transmission oil of specific specifications. If a mismatched oil was used, it might cause abnormal gear shifting and other problems. 2. ** Wrong oil change method ** - ** The filter has not been changed **: If the filter is not changed at the same time when the oil is changed, the impurities in the old filter may pollute the new oil and affect the performance of the transmission oil. - ** Inappropriate Oil Level **: If too much oil is added, the internal pressure will be too high; if too little oil is added, it may not be able to meet the requirements of the gear box's grease and heat dissipation. For example, in some automatic transmissions, precise control of the amount of oil was very important for its normal operation. - ** Incomplete cleaning (for the oil change of the circulatory machine)**: If the oil change of the circulatory machine is used, the sludge and deposits inside the transmission are not completely cleaned. The performance of the new oil will be affected after mixing the new oil with the old oil, and it may even block the oil path and the valve body. This was especially true for automatic transmissions that were thousands of meters long. Although the oil changer could remove the debris stuck to the main oil channel of the control module of the hydraulic transmission oil circuit board or the engine oil pan and the transmission filter, these debris would block the components such as the moment, the hydraulic transmission oil circuit board, and the transmission filter due to the flow of the pipeline, resulting in the blockage of the oil flow and the blockage of the relay. 3. ** Non-original oil problem ** - The use of non-original oil may not provide the same performance as the original oil. For example, some car owners reported that after changing to non-original oil, the feeling of the car changed, and there were problems such as stagnation. For example, after changing to non-original oil (such as Condo, ZF, etc.), the driving experience of the car was not as good as when using the original oil. ** 2. The situation where there is no need to change the original ** 1. ** Lifetime maintenance-free transmission ** - Nowadays, many transmissions were life-long maintenance-free. They did not need to be inspected or maintained, or they needed to be replaced after 10 years and more than 240,000 kilometers. If the vehicle's transmission is of this type, it may not be necessary to replace it at 6 years old, and it may introduce new problems due to the operation during the oil change process. 2. ** Transmission oil in good condition ** - If the transmission oil was not black, turbid, without impurities, and had no other smell at 6 years old, it meant that the transmission oil was in a good condition. In this case, replacing it might bring unnecessary risks, such as uneven mixing of new oil and old oil or quality problems with the new oil itself.

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.

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.

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."

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.

This statement was wrong. The oil in the CVS transmission needed to be changed regularly. The replacement cycle of the oil for the Nissan-made CTV transmission was generally once every 40,000 - 60,000 kilometers, but it was also affected by factors such as the vehicle's usage, driving conditions, and manufacturer's recommendations. If the vehicle is often driven in poor road conditions or high temperature environments, frequently overloaded or driven at high speeds, has a radical driving style, or the manufacturer has special recommendations, it may need to be replaced more frequently. If it was not replaced for a long time, the performance of the transmission oil would decline, and the impurities and impurities in it would increase, which would lead to increased wear of the friction parts, uneven shifting, abnormal noise, slow acceleration, and other problems. It might even cause the transmission to malfunction. If the vehicle was within the guarantee period, it might affect the validity of the guarantee if it was not replaced according to the manufacturer's recommendation. Therefore, in order to ensure the normal operation of the Nisshin CTV transmission, extend its service life, and avoid the risk of potential failure, the transmission oil should be changed regularly according to the actual situation.

The replacement cycle of the Nissan-made CTV transmission oil is usually once every 40,000 - 60,000 kilometers, but this is not absolute. If the vehicle uses a hybrid CVS transmission, 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 - 80,000 kilometers in advance. During the 120,000-kilometer guarantee period, it was also recommended to replace it every 60,000 kilometers. When it is found that the quality of CVS transmission oil is poor, such as blackening, smelly, colloid, iron filings, etc., or when there is weak acceleration, gear shifting, and unsmooth driving during the driving process, it also needs to be replaced in time, and it should not exceed 100,000 kilometers.
