The first model on which AVTOVAZ began installing a CVT is the Lada XRAY, then it will be installed on Vesta. The Jatco JF015E automatic transmission was borrowed from the Renault-Nissan alliance. The company claims that Jatco gearboxes have already proven their reliability on cars of the Nissan family (Juke, Qashqai, Sentra, Tiida, Micra, Note models) and Renault (Megane model). Is it really?
Garage myth
There is an opinion that life is easier for the CVT on Vesta and Xray because these are small class cars. But the curb weight of Vesta with the Nissan H4M engine and CVT is 1230 kg - not so little. For example, the Nissan Juke crossover is only 5 kg lighter, and the Renault Kaptur is 50 kg heavier than Vesta. In general, I would not make any allowance for the smallness and lightness of the Lada.
The compact Nissan crossover with the same power unit has an even lower curb weight than Vesta.

Main defects and malfunctions of the variator
1. High pressure pump
. It circulates the oil and creates pressure in the system. The weak link in this unit is the bypass valve. As it wears out, it can jam, this causes a drop in pressure in the system, which causes belt slipping (uneven operation of the pulleys). As a result, the cone plates wear out, and scuffs appear on the belt. The repair consists of replacing the valve and restoring the cylinder where it is installed. As a rule, there is no need to change the pump assembly.
2. Wear of cone plates.
If the wear is small and the scuffs are small, then grinding is possible. Otherwise, only replacement.
3. Seals on the belt
. The belt is not repaired, but only replaced with a new one.
4. Bearing wear.
With such a malfunction, noise appears in parking mode and when driving. The cones and belt are replaced.
5. Breakdown of the sun gear relative to the drum
(usually this happens with a mileage of 60,000 - 100,000 km.). With such a malfunction, the car moves backwards, but does not move forward.
6. Malfunction of the input shaft.
During operation, the separator is destroyed, the balls are knocked down and the bearing jams. Signs of a malfunction: a characteristic noise appears, and in the Drive or Reverse position the car stalls.
7.
The cone has a comb for
the speed sensor
. During operation, it may come off the cone itself. As a result of such a malfunction, the variator will not operate correctly.
Useful information | Typical faults | Repair
The CVT RE0F10A modification was intended for front-wheel drive and all-wheel drive Nissan vehicles with a volume of 1.6 to 2.5 liters.
According to many experts, this transmission is one of the best CVT designs in the world. 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.

How much does it cost to overhaul a variator?
On average, a major overhaul of a variator costs 100,000 rubles. This cost includes its removal/installation (about 9,000 rubles), replacement of faulty parts, filters, seals and oil.
Let us remind you that the variator is installed in tandem with the Renault-Nissan HR-16 engine. AVTOVAZ previously told why Renault engines are more reliable than previous models.

How to drive a CVT correctly?
— If the ATF oil has not warmed up to operating temperature (70ºC), it is not recommended to drive quickly. During fast accelerations, the variator belt protector (it is in the form of notches) will slip and wear out the surfaces of the cones. After warming up, the slippage disappears. — You can slip with a CVT, but very carefully and competently. You can't do it overheated or cold. — Switching quickly from D to R is dangerous. Over time, shocks will appear when shifting from park to D and R. Due to the lack of a pause between shifts, the splined connections of the planetary clutch, which are in contact with the friction discs, will wear out. As a result, you will have to change the planetary gears. — Long driving at 150 km/h is not recommended due to overheating of the box

Repair and maintenance costs:
The JF015E variator is a controversial gearbox and expensive to repair. Replacing coarse and fine filters, replacing the pan gasket, sealing rings and changing the oil along with labor will cost $130. Restoring the torque converter will cost from $110 to $180 Restoring the valve body will cost from $80, and repairing the shafts - from $70 Completely restoring the transmission - from $1500 to $2600 (If the cost exceeds, it is better to buy a contract variator) The cost of JF015E on the secondary market is from $1100 The price of installation services - from $80.
Application of JF015E
The JF015E is used in many Renault-Nissan-Mitsubishi alliance models with engines up to 1.8 liters and torque up to 160 Nm.

Typical problems of the JF015E box
The variator in question is quite reliable. The valve body and gearbox installed in the JF015E box do not cause owners any special problems, although they may sometimes suffer from “diseases” typical of these modules. But there are also some problems that are specific to the JF015E box.
Dirty oil
Sometimes a car with this gearbox starts to complain about jerking and uneven movement. There may be a number of reasons for this, but in most cases they are associated with degradation of the oil in the box and its contamination.
Important: dealers recommend changing the oil in the gearbox every 60 thousand km, but it is advisable to do this even earlier, at 20-30 thousand.
The wear products of the variator pulleys - metal filings and shavings - get into the transmission fluid of the box. Fractions should be captured by magnets, but this does not always happen effectively enough. Foreign components in the oil lead to accelerated wear of gearbox components, for example, the valve body. Its malfunctions lead to chaotic fluctuations in fluid pressure with subsequent movement of the box pulleys, as a result, the car moves unevenly.
About Jatco JF015E
Production of JF015E began in 2010. The transmission is a hybrid of a CVT and a two-speed automatic. Thanks to this, it was possible to reduce the size of the cones and reduce the weight and dimensions of the unit, sacrificing reliability. It was already not to hell before the 2015 modernization. The belt and cones could have become critically worn by 40 thousand kilometers. And the sun gear, which is responsible for switching between forward and reverse, burst along the weld. Fortunately, the resource is now much higher.
Theoretically, the presence of two additional gears should have relieved the cones from excessive load in critical conditions. This is when the belt is in its extreme positions on the cone, near the shaft or the edge of the pulley. Also, in these belt positions, the efficiency of the gearbox is reduced by approximately 85-90%.
