In fact, modifications to the CVT transmission JF011 is a second generation CVT, in which control was carried out using a fully automatic system. The variator was installed on Mitsubishi, Nissan, Renault and a number of American Dodge cars. Currently, the transmission is one of the most common CVT automatic transmissions in the world. REPAIR OF JF011E CVT. TYPICAL FAULTS (LINK)
The CVT JF011E automatic transmission has proven itself to be the best. This is a reliable box that is durable and easy to maintain. It is also necessary to note its affordable cost. One of the features of this automatic transmission is the use of two filters at once. This ensures maximum quality of the lubrication system, which in turn extends the service life of the transmission. This feature with two filters must be remembered when performing service work. After a run of 50-60 thousand kilometers, it is necessary to change the oil in the gearbox. Two filters are changed at the same time as the oil.

Features of the JF011E variator
Among continuously variable transmissions, CVT Jf011e occupies a leading position in popularity among well-known automakers:
- Nissan;
- Peugeot;
- Renault;
- Citroen; c
- Samsung;
- Mitsubishi, etc.
On many cars of branded companies, the jf011e variator has successfully replaced traditional automatic transmissions.
The Jf011e box design includes two oil filters:
- Internal oil filter 321010C.
- External filter 321010CA.
Filter element brand 321010C closed type. It is housed in a metal housing with a steel mesh and is installed in the transmission pan. Depending on the dimensions of the pan (depth), the coarse filter is equipped with a special intake tube 14, 21 or 30 mm long. The mechanism is designed to filter the working fluid of the valve body. Replacement of 321010C is carried out simultaneously with oil and worn, burnt friction discs.
During current, major repairs, the metal oil filter is washed from harmful deposits of burnt oil with a special washing solution. If the small cells of the steel mesh are clogged with an adhesive composition in the form of refractory resins from worn friction linings, the valve body filter must be removed and replaced with a new mechanism.
The fine filter 321010CA is made in the form of a cylindrical cartridge. It is located below the heat exchanger on the left side. The device carries out additional fine cleaning of the lubricant. The service life of the Jf011e CVT variator depends on the quality of transmission oil filtration.
Advice: Experienced drivers recommend changing the filter cartridges of the Jatco Jf011e variator on cars with high mileage every time you change the ATF gear oil.
Interesting: Unlike standard automatic transmissions, when operating the jf011e variator, a short-term deviation of the oil level from the norm is allowed. At the same time, the stability and stability of the variator operation depend on the purity of the lubricant.
Old used oil quickly causes damage to:
- belts;
- chains;
- cone;
- O-rings;
- valve body solenoid valves (solenoids).
In accordance with the recommendations of the Jf011e CVT manual, the degree of aging and contamination of the lubricant in CVTs is determined using a control oil dipstick and a clean napkin. During the process of changing ATF transmission oil, the transmission oil pan is dismantled and the condition of special magnets is assessed to eliminate the need for major repairs.
Advice: When performing repair and restoration work, experienced auto mechanics use “Overall Kit” 321002-TK repair kits of proven quality for Jatco CVT variators. Transtek's products are popular because high-quality rubber raw materials are used in the production of gaskets for variators.

When carrying out service work, it is recommended to use original spare parts and lubricants that approved by the manufacturer. Attempts to save on oil quality will invariably lead to problems when operating the car. We also note the fact that the variator has a complex design and places increased demands on the professional level of the craftsmen who carry out repair work. Therefore, if repairs are necessary, you should contact only original service centers.

With proper operation, this gearbox can easily run more than 200 thousand kilometers without the need for complex repair work. In some cases, pump seals and oil pan gaskets fail. Repair work in this case consists of replacing oil seals and leaky gaskets. In rare cases, wear of the gears is observed, which forces a rather complex and expensive overhaul of the gearbox.
Typical faults
The JF011E is perhaps the record holder among all continuously variable transmissions; in total, several million such gearboxes have been produced, which are currently being successfully used. In the first years of its production, some design flaws were eliminated and problematic components were replaced, which significantly improved the reliability of the transmission. This made it possible to increase the interval during scheduled repairs of the JF011E variator , and the gearbox itself could serve for 10-15 years or more without causing any special trouble to the car owner.
Torque converter malfunctions
The weak point of this transmission is considered to be the torque converter locking clutch, which was changed almost every 100 thousand kilometers. Such malfunctions can be identified by the appearance of a characteristic hum and loud howl when accelerating. You should not delay such repairs, since worn-out torque converter consumables actively contaminated the transmission fluid with wear products, which was the main reason for the failure of the valve body and other expensive components of the variator.
Step motor failure
A typical breakdown was the failure of the stepper motor, designed to regulate the power that is transmitted to the drive axis. Using this electric drive, the distance between the cones was adjusted. During operation, the step motor was subject to increased loads; in particular, such an electric motor quickly failed due to frequent overheating. In the presence of such malfunctions, the box was completely blocked, after which the car had to be delivered to the service by a tow truck.
If it was necessary to replace the motor, both new electric drives and restored rebuild motors, which had a much lower cost, could be used. Most car owners, in order to save money, decided to install such a restored step motor. Whereas, when carrying out a major overhaul of the JF011E variator , new step motors were purchased, which made it possible to completely restore the transmission, which ran for another 200 thousand kilometers.
Hardware problems
The weak point of this transmission was the bearings of the driven and drive shafts, which wore out under increased loads, causing critical belt wear. They had to be replaced as a set, which prevented problems with the valve body and oil pump. The aging of the bearings could be determined by the appearance of the howl of the variator and noticeable vibrations.
Also, on significant runs, it was necessary to replace the Bosch push belt, which stretched and wore out under increased loads and prolonged use of cold, dirty oil. Timely implementation of such repairs of the JF011E variator prevented damage to the cones and the need to replace them. In order to reduce the cost of such repairs, used belts with at least half or more of the original residual life were often ordered.
In rare cases, it was necessary to replace the cones, which were replaced along with the discs and belt. Often such work was required to be performed in cases where the car owner neglected the existing symptoms of malfunctions, did not change the oil in a timely manner, or practiced an aggressive style of driving the car. It is also possible to use both original new cones and install used spare parts in excellent technical condition.
When performing major overhauls, it was often necessary to replace the sun gear along with the clutch hub. If you neglect such malfunctions, steel discs often break and the belt with cones suffers. Simultaneously with this transmission restoration, the condition of the differential and shaft bearings was checked.
Oil pump malfunctions
When performing scheduled repairs of the JF011E variator, it was necessary to change the pump seals, which was a mandatory prevention of serious pump malfunctions. To restore the broken pump, an inexpensive repair valve or a Sonnax repair kit was used. At the initial stages of such malfunctions, it was possible to install the repair kit in a standard seat, without additional adjustment of parts.
The oil pump in this box was a weak link; due to the increased load, its malfunctions were often noted, especially during overheating and increased load on the transmission. Prevention of such breakdowns included regular replacement of pump seals, diagnostics of the condition of this unit and its scheduled repairs.
Repair
The planned repair of the JF011E variator was carried out taking into account the technical regulations of the automaker; an original repair kit of bushings, gaskets, clutches and other parts was used. The radiator of the oil cooling system was cleaned, which made it possible to prevent overheating of the variator and the need for its expensive restoration. Typically, such work was carried out on runs of 150 thousand kilometers. Regular scheduled repairs were the key to the absence of serious malfunctions, allowing existing breakdowns to be eliminated at the initial stage, which somewhat reduced the car owner’s costs.
On runs of more than 300 thousand kilometers, this automatic machine needed a major overhaul, including restoration of the valve body, replacement of solenoids with clutches, service of the oil pump and troubleshooting of the iron part of this continuously variable transmission. Qualified repair work made it possible to extend the service life of the machine, which ran for more than 200 thousand kilometers. For such work, both new spare parts and repair kits and high-quality used spare parts, including belts and cones, could be used.
