The reason why the acceleration of the CTV transmission was weak after changing the oil was probably because the CTV system of the vehicle needed some time to adapt to the new oil. During the adaptation period, it would feel a lack of power. It could also be because the correct oil was not used, or the quality of the oil did not meet the requirements. In addition, other problems with the CVS system could also cause this situation, such as wear and tear of the transmission belt or sensor failure. If the problem persisted, it was recommended to check if the transmission oil was the correct model. You could also consider using the diagnosis instrument to re-learn the characteristics of the electromagnetic valve and the stepping motor. If there were no problems, the transmission needed to be disassembled to check if the internal chain and the drive and driven cone were abnormally worn. Once there was serious wear and tear, the transmission may need to be overhauled. The novel " Watching the Moon on Fish Island " is equally exciting. Everyone is welcome to click and read it!
Different maintenance measures should be taken according to the specific fault situation: 1. ** Repair related to the Nippon CLV8 transmission ** - Japan's CLV8 transmission claimed to be maintenance-free for life, but it was often late to repair it after it was obvious. If the computer detected fault codes such as P0846 hydraulic sensor/switch, P17F2 CLV vibration, etc., the car before 2019 might have problems when driving 70,000 to 80,000 kilometers. Although the transmission after 2019 had upgraded the valve body of the Yin-Yang Hardening process, it might also have problems when driving 150,000 to 200,000 kilometers. If the valve body is worn out, the pressure relief pressure is insufficient. The insufficient oil pressure will cause the chain cylinder to not clamp the steel belt tightly, resulting in slipping and weak acceleration. It can be solved by replacing the valve body in time. If the maintenance is not timely, it will cause the chain and chain cylinder to be worn out. At this time, the transmission box needs to be disassembled. When the chain cylinder is not seriously worn out, it can be used after being polished on the machine. The old JF-series oil pump pressure regulating valve was easily damaged by metal debris. It could be replaced with a separate oil pump valve from Sonax, USA. If the violent driving continued after the transmission alarm, it would cause the steel belt to break and suddenly break down during driving. Therefore, this series of transmissions had to be dealt with in time after the failure. The longer the delay, the higher the maintenance cost. 2. ** Bunchy CLV Transmission Repair ** - Bunchy CVS transmissions were commonly found in domestic Mustang, Seahorse, Great Wall and other models. If there is a serious low-speed shaking accompanied by idling when driving, there may be a lot of sludge and iron filings under the oil pan after dismantling, which may be caused by the damage of the pressure cylinder and oil pump. This kind of transmission had a higher chance of breaking down. It could not withstand large amounts of power and was afraid of violent driving. 3. ** General CLV transmission repair ** - In order to repair some faults of the CVS transmission, you can find a professional reamer and a positioning tool for the reaming hole. Before maintenance, the positioning tool of the drilling hole was installed into the output shaft hole of the transmission. The worn bearing base was enlarged by the reaming knife. After the drilling hole was completed, the positioning tool was removed, and the specially customized steel sleeve was installed. Then, the input shaft of the original vehicle was installed in place, which could solve the problems of abnormal sound of sudden acceleration and abnormal sound of turning. 4. ** Attention Points for Repair ** - Before repairing the transmission, no matter what the fault is, before dismantling the transmission, you must confirm the repair price with the maintenance manufacturer and sign the relevant maintenance agreement to avoid the second price increase after dismantling (because once the transmission is dismantled, even if it is not repaired, you still need to pay the dismantling fee). After the repair price was determined, it was necessary to further determine the quality assurance, whether it was a full-box or partial quality assurance. The whole box of quality assurance could let the car owner have no worries and reduce after-sales disputes. At the same time, the transmission oil needed to be changed in two years or 50,000 kilometers. Gravity oil change was recommended for CVs.

There were many kinds of abnormal sounds from the CVS transmission. When the car sped up or accelerated, there was a " whistle " that was sometimes loud and sometimes soft. This might be due to the wear and tear of the metal-to-metal friction parts inside the transmission, such as bearings, cylinder blocks, gears, conical wheels, etc. This wear and tear was mostly due to the failure of the defoamer component in the transmission oil, which caused the transmission oil to be stirred violently and produce a large number of bubbles. The places that were supposed to be smoothed by the oil film were filled with bubbles, causing metal " cavitations " and producing strange sounds. The Audi A6L's dual-mass flywheels equipped with CVs might make a cooing sound, especially in the dead of night or in quiet parking lots. When idling or in reverse and forward gear, this sound could be caused by a problem with the dual-mass flywheels. The Toyota's CTV transmission would make strange noises when accelerating and retracting fuel in low-to-medium speed. In addition, the abnormal sound when the vehicle starts may be caused by the suspension system failure due to the loosening or damage of the engine support; The abnormal sound when turning may be related to the steering system and the suspension system; The abnormal sound when driving in good road conditions may be caused by the loosening, wear and tear of the brake system components, the brake drum out of round or the uneven brake disc; It may also be a problem with the bearing connecting the moving and static parts. It could also be that the internal valve body was blocked by dirt and impurities, and the oil pressure could not be effectively adjusted, resulting in knocking, impact, and slipping; or the internal bearing of the transmission was worn out; the inner circle and the journal of the main pressure cylinder were in contact with each other, and the journal was loose and worn. The appearance of pockmarks on the journal would also produce abnormal sounds. The novel " Watching the Moon on Fish Island " is equally exciting. Everyone is welcome to click and read it!
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.

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.

Different types of transmissions had different oil replacement intervals. For the manual transmission, due to its simple structure and durability, the oil change cycle could reach 100,000 kilometers, or even 200,000 kilometers without changing. There was also a view that it could be replaced once every 150,000 - 200,000 kilometers. For automatic transmissions like Mercedes-Benz, it was generally recommended to change it every 60,000 kilometers. Dual clutch transmissions were generally recommended to be replaced once every 100,000 - 120,000 kilometers. If the conditions of the car were relatively bad, such as frequent short-distance driving, driving on dusty and rough roads, driving in places with salt or corrosive substances, driving in cold seasons, driving in sandy areas, driving in hot weather, frequent use of vehicles in mountainous areas, frequent towing, commercial vehicles, frequent speeding, etc., some manufacturers would recommend changing once every 100,000 kilometers. There were also opinions that the transmission oil needed to be changed for 40,000 to 60,000 kilometers in three years. There were also opinions that most of the transmission oil was maintenance-free. A small number of transmissions only needed to change the transmission oil once. Very few, such as the CZT of the Nirvana and the old six-speed automatic transmission of GM, needed to be replaced. In addition, some cars, such as the Volkswagen Sagitar dry DSG, were officially declared maintenance-free. The novel " Watching the Moon on Fish Island " is equally exciting.
