Your transmission plays a massive role in efficiency, since that is the primary job of a CVT setup. Fuel costs money, and the less efficiently your car performs, the more you’re shelling out for the gas or diesel to keep it going. CVT transmission fluid prevents the gears from scraping at each other through lubrication. Grinding your gears is a common phrase for frustration, because it is nothing but damaging. Anytime two surfaces rub against each other, like the gears controlled by your transmission, small bits scrape away. Proper transmission fluid ensures this iconic smooth transition, regardless of the incline. It’s the result of issues with gear transition, one of the reasons CVT transitions became popular in the first place. That kick you feel when challenging a steep highway hill doesn’t actually need to be there. Properly formulated CVT transmission fluid mitigates this issue since it is specifically made to lubricate this type of transmission. It sounds great, but it also means faster wear simply because the fluid is circulated more because of all the gear ratio changes. CVT transmissions are popular because they are designed to adapt the gear ratio to optimize engine efficiency regardless of speed. Major repairs JF015E variators are performed on solid runs, iron is sorted and changed, the torque converter is cleaned, and the worn-out oil pump is restored, changing the tired valve in it. Depending on the condition, inspect the oil pump and conduct a bulkhead of the iron part with the replacement of individual components. Restored hydraulic torque convertor, changed the set of frictions, all bushings, rubberized seals and gaskets were used. Rebuild JF015E CVT transmissionĭue to the presence of a torque converter that took on the part of the load, it was possible to slightly increase the interval of the planned restoration of the transmission, so the variator had to be opened and repaired every 150 thousand kilometers. The variator was configured in such a way as to provide not only fast acceleration but also almost imperceptible power switching for the driver. This allowed to increase the service interval and saved the car owner from having to open the transmission every 100 thousand km mileage, performing its defects, bulkhead, and replacement of worn parts. The cones in this variator were positioned in such a way as to exclude the impact of the belt at the edges, and it was here that increased wear was noted, requiring major repairs of the transmission JF015E. This made it possible to simultaneously increase the reliability of the design, implementing the power characteristics of the engines with maximum efficiency. In fact, it is a two-stage variator, which had smaller cones with an increased gear ratio. The JF015E variator had three clutch packages and two forward gears. The presence of a full-fledged torque converter in the variator, which softened the load on the shafts and planetary transmission, was a real revolution for the continuously variable transmission. As for iron, it was necessary to change the stretched belt every 150 thousand km mileage, but the cones, thanks to their special design and wear-resistant materials used, could serve 200 thousand km mileage or more.

It was recommended to install an external radiator on transmissions with a large mileage. Typical JF015E ProblemsĪ typical fault on these CVT JF015E variators is the wear of the torque converter consumables as well, not too powerful heat exchanger used, which required regular cleaning. This continuously variable transmission was installed on various cars, its service, and CVT7, JF015E, RE0F11A variators rebuild was not particularly difficult, so it was popular with various car manufacturers. One of the features of this transmission was the presence of a torque converter, which significantly reduced the load on the entire structure, extending its operational life.

In 2010, the Japanese company Jatco released a new generation of JF015E variators, which were intended for use on small cars.
