The reliability of the Nissan X-Trail CVT has been the subject of fierce discussion in many forums. Most Nissan X-Trail drivers were able to appreciate the merits and reliability of the novelty. The Nissan X-Trail is equipped with the most modern CVT RE0F06A or RE0F10A (JF011E).

As indicated in the vehicle passport, the service life of the Nissan X-Trail variator before the first major scheduled preventive maintenance is about 100 thousand km. It is recommended to change every six months. In fact, the resource of the Nissan X-Trail variator is unlimited with correct use and timely maintenance.

Abrasion of the pulleys with proper operation is minimal, the transmission chain should be replaced as needed, on average once a year. Diagnostics of the car and automatic transmission is carried out once every six months. Choose service stations that work with the Nissan X-Trail automatic transmission.

The CVT on the Nissan X-Trail is not the first series of transmissions with a smooth transmission. Early versions of the variator were run in, studied in different situations and improved. The Nissan X-Trail box is the result of major improvements and design upgrades that make user errors less critical.

Briefly about the history of creation

Box automatic nissan X-Trail, in which instead of classical transmission there is a variator, appeared on the market about 10 years ago. This time was enough to figure out if the variator is reliable as the basis of a modern transmission.

Over 10 years of mass use, design developments and improvements have accumulated, which made it possible to release new model. Improvements have touched precisely the mechanical part of the automatic transmission. According to the test results, it can be noted that CVTs have become more reliable in the new generation.

The idea of ​​a smooth transmission is not as new as it seems at first glance. The device was actively used in the Middle Ages in the construction of mills, later in the creation of various agricultural machinery. The variator resource or service life, in the case of mills, is calculated in decades. It would be strange not to use such a wonderful idea, the authorship of which is attributed to Leonardo da Vinci. The Nissan X-Trail automatic transmission is the embodiment of the ideas of the ingenious mechanic of the Middle Ages in a modern version.

The X-Trail variator is produced Japanese company Jatco. Automatic transmission Nissan X-Trail installed on Peugeot cars, Citroen, Mitsubishi, Honda.

The main task of a smooth transmission using cones is to maximum use motor power and load regulation. Saving motor power when using the variator is obvious. The transmission runs softer, driving becomes easier. Also, the device allows you to take care of the motor, reducing depreciation.

What are the myths about unreliability?

Reliability problems are primarily associated with improper operation and design flaws that allow the driver to perform actions that greatly harm the car engine and destroy the automatic gearbox.

As practice shows, they complain about reliability experienced drivers, or who consider themselves as such, have not read technical description and believing themselves unsurpassed racers. There is a rumor among street racers about the unreliability of the CVT transmission. It's easy to figure out why. The foppishness and roar of the engine at traffic lights is expensive for owners Nissan X-Trail. When shifting hard, the steel belt slips and runs directly over the surface of the pulleys like sandpaper, scratching the surface and damaging the cones. Then follows fast moving, iron filings do not have time to fall into the filter coarse cleaning, get into the mechanism and completely disable the automatic transmission. Diagnostics shows the destruction of the automatic transmission, even if the resource has not been exhausted. Beginners carefully read the rules of treatment and successfully master new box machine. Real resource CVT Nissan X-Trail is almost limitless.

Mistakes of experienced drivers

An experienced driver, sitting behind the wheel, automatically warms up the engine and oil by pressing the gas pedal. Warming up is carried out until light signal on the control panel.


Metal variator belt

In the case of a CVT, depressing the gas pedal causes the steel transmission belt to rub hard against the cones. This leads to damage and abrasion of the belt. A torn or damaged belt is the most common cause appeals to service centres. In addition, metal chips and belt fragments clog the system, rendering it unusable. To save the system, at a minimum, you need to urgently change the oil and filter. The problem is eliminated by installing an additional oil heating machine in the box. The Ready-to-Work indicator lights up almost immediately.

How many times to measure the oil level per 100,000 km? Diagnostics of the Nissan X-Trail CVT still requires special equipment. In some models, even measuring the oil level can only be done at specialized service stations. According to the instructions, it is recommended to check the Nissan X-Trail automatic transmission every 30 thousand km. Therefore, for 100,000 km, you will need to visit the maintenance station 3-4 times a year, as needed.



  • With engine running on idling you should be careful, shift gears smoothly. When the gears are working, the transmission chain is immediately transferred to the desired gear. When using pulleys, a sudden change in speed causes the steel belt to run over the surface of the pulleys and cause damage. The automatic transmission resource is prematurely developed and the service life of the Nissan X-Trail automatic transmission is reduced.

Improvements and enhancements

Consider what changes the Nissan X-Trail CVT includes.

  1. The Nissan X-Trail CVT device has become easier to maintain.
  2. Access to the variator has become easier, the coarse filter can be easily removed and washed well.
  3. The X-Trail variator is equipped with magnetic traps (they are located on the pallet).
  4. It is not necessary to warm up the oil at start-up. AT Nissan design X-Trail added a special oil heater that is activated when the engine is started. The addition of an oil heater to the new generation CVT RE0F10A engines, the Nissan X-Trail CVT, eliminated the need for warm-up. An engine with a Nissan X-Trail gearbox immediately displays readiness for operation on the control panel, which saves the driver from the desire to press the gas and ruin the engine with iron chips.
  5. In the CVT RE0F10A Nissan X-Trail engine, the drive pulley is now single-piston. The pressure in the X-Trail drive pulley circuit was increased to 60 kg/cm 2 . The pulleys themselves have become lighter and their wear has significantly decreased.
  6. To reduce temperature and reduce adhesion, foaming, an air cooler is added.

How often do you visit a car service?

How many times do you need to change the oil and what is the resource for each shift? According to the manufacturer's recommendation, the Nissan X-Trail transmission fluid should be changed every 100,000 km.

AT Russian conditions oil change, diagnostics and service are required more often due to extreme conditions driving. When changing the oil, each time the filter is changed and the trap is washed, the coarse filter. The coarse filter is a container into which coarse mechanical particles, chips, metal filings fall. The coarse filter reduces the depreciation of the automatic transmission and increases the working life.

List of conditions considered extreme

  • The temperature is below 0 degrees. In our area, such an “extreme” temperature can be six months.
  • Frequent starting and stopping of the engine and work on Idling. Traffic jams and traffic lights contribute to such an "extreme" in any major city.
  • Dust in the air.
  • trailer towing, full load, taxi, post office, courier delivery service, any commercial operation.

With enhanced operation, the resource of the automatic transmission is reduced. If the car is running Russian roads, it is desirable to undergo MOT more often.

CVT or continuously variable transmission

Nissan X-Trail 2.0: sand CVT

AT automotive community there is a strong prejudice against CVT gearboxes: it is believed that the boxes are short-lived, break quickly, demanding on operating conditions and unsuitable for installation in cars with powerful engine. Nissan tried to dispel this prejudice by putting a CVT box in a fairly powerful X-Trail SUV.

Interesting: according to technical passport, variator to the first "serious" Maintenance should work without breakdowns up to 100 thousand km. run. And when timely replacement transmission oil and other service procedures for the Nissan X Trail, the variator resource is theoretically unlimited.

If the gearbox is operated correctly, the pulleys are subject to minimal abrasion, the gearbox chain must be replaced at intervals of about once a year, and the machine, including the gearbox, should be diagnosed every six months.

Reasons for opinions about the "unreliability" of boxes

There are two main reasons why a particular automotive solution acquires a reputation for being unreliable:

  • not correct operation;
  • design flaws made by the developer, as a result of which the parts experience increased wear, or the driver gets the opportunity to operate the nodes in non-standard modes, harming the box and engine.

In practice, drivers who are not familiar with the rules for operating the box complain about the "unreliability" of the variator. This is especially true for fans of fast, sharp driving, and street racing: among the latter, “variator unreliability” has become a byword.

The reason for this is obvious. With a sharp start with slipping and the roar of the motor, when the box is operated in extreme mode, which is part of its design, the steel belt slips on the pulleys, damaging and scratching the metal. Further, during fast driving, the resulting metal shavings enter the oil, not having time to settle in the box filter, penetrate into the channels and mechanisms of the box, completely disabling it. So you can "kill" even an almost new box, with an incompletely depleted resource.

More luck with CVTs for novice motorists, who, as a rule, carefully study the instructions for the car and the rules for operating the box thereof. Their box can “walk” for decades, undergoing periodic scheduled maintenance.

Overview of the Nissan X-Trail CVT

Story

A continuously variable transmission is not a new idea, and has been known since the Middle Ages. In particular, Leonardo da Vinci reflected it in his drawings. And the CVT box embodies these ideas in a modern, high-tech design.

The Jatco CVT was installed on the Nissan X Trail about 10 years ago, and since then the manufacturer, car services and motorists have already gained solid experience in operating these boxes, repairing and eliminating various problems.

box device

The Nissan CVT is based on the principle V-belt transmission: in the box there are pulleys consisting of two cones connected by a special belt, which is responsible for the transmission. The gear ratio of the box changes by changing the distance between the driving and driven pulleys, which is done by a special stepper motor boxes. In addition, the CVT box includes planetary gears that are responsible for engaging the reverse gear.

There are several main elements hidden in the Jatco CVT box body:

  • variable speed pulleys;
  • a steel belt connecting them;
  • valves and solenoids box ;
  • planetary gears;
  • clutch packs for reverse gear and Drive mode of the box;
  • high pressure pump;
  • box control box.

In an extremely simplified way, the variator can be compared with a bicycle chain drive, where there are driving and driven sprockets connected by a chain, only instead of sprockets there are pulleys, and instead of a chain there is a box belt.

The input pulley of the box is connected to the engine in the form of a clutch, always operating in mode D. output shaft boxes during operation is pushed by the primary due to the force transmitted by a special belt.

The box belt consists of many steel segments connected to each other by a dense steel tape.

Important: the box belt is pushing. This means that the force transmitted by it from the primary pulley pushes the secondary, and does not pull it along.

It is assumed that the box belt is subject to little wear, since the steel is very strong and does not compress. The entire belt element of the box works as one steel body that transmits torque.

If you need to change gear ratio, the transmission control module (TCM) changes the distance between the gearbox pulleys, resulting in:

  • the primary pulley of the box rotates more slowly - the gear is lowered;
  • faster rises.

If you need to switch to reverse, the planetary gear of the box is activated (in normal driving mode it is passive). At the same time, the possibility of changing the gear ratio is blocked by the box for safety reasons - to avoid accidental acceleration when reversing.

It is imperative to create in a box high pressure to avoid belt slippage and damage to metal surfaces. For these purposes, special technological methods and special transmission fluids are used.

The nominal pressure developed by the oil pump of the box is 55 bar, and the maximum possible is up to 60. Several regulators are used in the CVT box to provide indicators:

  • maximum 4 bar - for the lubrication and cooling system of the box;
  • up to 10 bar - for the torque converter unit;
  • up to 15 bar - for box clutches.

Common Problems

CVTs on the X-Trail are characterized by a series typical faults, some of which are purely “age-related” or are associated with poor maintenance of the box.

Noise from the bowels of the box

This is due to wear and destruction of the box bearings. When this happens, the driver hears the hum emitted by the box. This usually happens with a run of about 50 thousand km, and is eliminated only by replacing damaged elements.

Box bearings can become unusable if wear products (metal chips and other impurities) get into the system. Therefore, it is desirable.

Important: together with the bearings of the box, it is advisable to replace the belt as a preventive measure.

The consequences of the destruction of the box bearings:

For complete replacement you will need 2 four-liter canisters - with a small margin.

When to change the oil in the X-Trail CVT
On average, an oil change in a Nissan X-Trail T31 variator is recommended after 50-60 thousand km. run. Some drivers try to prevent possible faults boxes, changing the fluid after 40-50 thousand km, but this measure seems unnecessary.

  • At the next stage, the pallet is dismantled and the rest of the liquid is drained.

It must be cleaned of metal waste and dust accumulating on the bottom of the box tray, which is specially magnetized to trap foreign particles.

  • Replaced old gasket.
  • Next, the old box oil filter is removed and a new one is installed.
  • After installing the filter, reassembly is carried out.


There are many rumors about the operation of Jatco CVTs. Someone was lucky with the purchase of a car, and someone after a few tens of thousands is forced to change the box under warranty. What determines the endurance of this node? What is the actual CVT resource on the Nissan X-Trail?

CVT Model RE0F10A

Since 2007, Nissan has decided to equip X-Trail SUVs with CVT-type gearboxes. The body of the first generation T31 was equipped with a Jatco RE0F10A variator (aka CVT-7).

Its power is designed for engine size from 1.6 to 2.5 liters. Such data provide dealer centers. However, the Jatco website indicates slightly different volumes - from 1.6 to 1.8 liters. If the CVT-7 is really designed for small cars, then it becomes clear why it is so difficult for him to work out his resource without breakdowns.

The torque of small cars reaches a maximum of 180 Nm, while engines with a volume of 2 liters or more give out from 200 Nm. The variator can not cope with such a load.

Aggressive driving creates the need for a sharp shift between gears, and since there are many rubbing joints in the design of the variator, its wear accelerates significantly. So a lot depends on whether the car owner himself is on the Nissan X-Trail.

Weak spots

On the operation of which elements of the variator on the Nissan X-Trail T31 does its service life depend?

The main load during gear shifting is borne by the pulley bearings, the pulleys themselves and the rotation transmission belt from the drive shaft to the driven one. The nuance is that these pulleys are absolutely smooth, and the engagement with the belt occurs only due to friction.

According to the owners, the variator on the Nissan X-Trail of the T31 generation makes itself felt after 80,000-100,000 km, although the promised resource is 200,000.

Bearings wear out first, starting to make a characteristic hum. It depends on them the tension of the belt. If the bearing does not cope with its function, the belt tension decreases, it begins to slip, preventing the shafts from signaling a gear change. At the first stage of the malfunction, the variator box on the Nissan X-Trail "troit" (jerks appear). This is because the pulleys, turning idle, are deformed, getting scuffed and scuffed.

There is an element on the valve body that regulates the gear ratio - this is a step motor. He "monitors" the position of the accelerator pedal and driving mode. The transmission of information goes to the moving elements of the pulleys due to the foot of the step motor, which is quite fragile and wears out quickly, which leads to the operation of the variator at only one speed.

Repair of the variator on the Nissan X-Trail T31 is quite problematic: if there are spare parts for replacement, then their price will be unpleasantly high. The service can carry out troubleshooting and make an estimate. But if the warranty is still valid, experts recommend replacing the variator with a Nissan X-Trail.

Model RE0F10D (CVT-8)

Refinement of the type of variator on the Nissan X-Trail CVT-8 made it possible to increase its resource and endurance to an aggressive driving style.

The weight new transmission reduced, made more compact oil pump. We reduced the friction force of the belt on the pulleys by 40%, thereby reducing the pressure on them. To save fuel change gear ratio made it stepwise.

According to the owners' feedback on the variator on the Nissan X-Trail CVT-8, we can assume that it lasts longer. Its resource is designed for 250,000 km of operation.

Features of the operation of Jatco variators

The variator is fundamentally different from or "robot". It has no gears, due to which the load on the engine is reduced.

How to use the CVT on the Nissan X-Trail correctly, and what driving style to follow so that the box lasts longer?

  1. While the car is warming up, do not press the gas pedal in an attempt to speed up the process. The box responds to the accelerator even in neutral position selector.
  2. Gives a quick start huge load on the belt and pulleys, multiplying their wear.
  3. Driving over rough terrain adversely affects the condition of the variator.
  4. A car with a CVT transmission must not be towed or attempted to be started by spinning the wheels (“from the pusher”).
  5. It is not recommended to tow vehicles other than a car trailer.

Owner reviews about the variator on the Nissan X-Trail, its features, boil down to the fact that this unit was created for a leisurely ride on flat roads.

and TO

According to the manufacturer's regulations, maintenance of the variator should be carried out every 60,000 km of operation. For reinsurance, car owners try to undergo maintenance more often - after 40,000-50,000.

On the "Nissan X-Trail" you can spend it both at the service station and on your own.

To replace the transmission fluid in the variator, you must have:

  • oil;
  • mesh filter and oil cooler filter;
  • gaskets for sump and oil cooler;
  • waste oil container.

CVT oil

Considering which variator is on the Nissan X-Trail, the transmission fluid is also selected. For the T31 body, NS2 oil was produced, for the T32 body - NS3.

NS3 oil is designed for non-radiator CVTs and operation at over high temperatures. It has reduced viscosity, and, according to the developers, is suitable for both CVT-8 and CVT-7. However, owner reviews of the Nissan X-Trail CVT with a CVT-7 box running on NS3 indicate that extraneous noise may appear due to a lack of a lubricating oil layer.

Replacing the transmission fluid in the CVT-7 variator

You need to start the procedure by warming up the engine and the variator box on the Nissan X-Trail. Then:

  1. We drive the car onto the overpass. A viewing hole is also suitable.
  2. We unscrew the engine protection and remove the left wheel.
  3. The fender liner does not need to be removed completely, only half.
  4. We substitute the container for the waste liquid under the drain hole and unscrew the plug.
  5. You will have to wait about half an hour until all the liquid drains.
  6. Oil also collects in the sump. We remove it and drain the oil residues.
  7. If the mesh filter can still be washed with diesel fuel or carburetor cleaning fluid, then you can save money, but if not, you will have to change the filter.
  8. We thoroughly wash the magnets and the bottom of the crankcase.
  9. We insert the mesh filter (washed or new).
  10. We install a new gasket in the pan and return it to its place.
  11. Remove the battery and move to the side air filter. You now have access to the oil cooler filter. We take it off.
  12. Install new filter and cooler gasket.
  13. We return everything to its place.
  14. Fill with new transmission fluid.
  15. Check the oil level with a dipstick.

Changing the oil in the CVT-8 variator

The peculiarity of the CVT-8 is that it does not have a factory probe. You can check the level by topping up with new oil or contact a service station. There is a dipstick that is inserted into the filler neck.

To change the oil you will need:

  • washer for drain plug;
  • pad;
  • coarse filter and ring to it;
  • transmission fluid (5 l - for partial replacement, 12 l - for complete replacement with removal of the pan);
  • filter ring fine cleaning and himself;
  • ring for level control plug.

As in the case of changing the oil on a CVT-7, the machine must be put on a lift or viewing hole. AT this case you will need an assistant and a diagnostic scanner. If there is no scanner, it can be replaced with a thermometer (necessarily digital) on the pallet.

To gain access to the bottom, we drive the car into a pit or a lift. Further:

  1. Unscrew the drain plug. Up to 5 liters of oil should flow out.
  2. Remove the pan and coarse filter, wash them.
  3. We put everything in place. If the filter is not subject to further operation, we change it to a new one.
  4. If needed partial replacement, then fill in the oil, set its level, and this ends the procedure.
  5. For a complete replacement, fill in 3 liters transmission fluid through the hole on top (the one in which the probe used to be).
  6. We start the engine and pass the selector through all the positions of the box, stopping at each for 5 seconds.
  7. Drain the oil and repeat the process.
  8. We are waiting for the temperature of the box to be 35 ° C.
  9. Here you will need an assistant who will start the car.
  10. Unscrew the overflow plug. Fill with oil until a leak appears from the neck.
  11. We start the car and pass the lever through all ranges with a delay of 5 seconds. We fix the lever in the "P" position.
  12. Pour in the oil again until it starts to overflow. Screw the plug into place.

The transmission fluid has been completely replaced. Now you can reset the counter value.

Variator failure symptoms

Timely replacement of filters and fluid in the box, proper operation, of course, extend the life of the variator. However, breakdowns can still occur. To date, some service stations undertake to carry out both partial and overhaul this node, and even give a guarantee for their work.

Here are a few signs that you should contact them immediately:

  • slipping even with a smooth press on the gas pedal;
  • The gearbox goes into emergency mode (on dashboard indicator appears).
  • vibration;
  • jerks or bumps when switching between any gears, both on a warm car and on a cold one;
  • transmission disappears or does not turn on;
  • inhibited reaction to a change in speed;
  • extraneous noise;

In reviews of the CVT on the Nissan X-Trail, it is often mentioned that such symptoms in many cases can still be corrected without resorting to replacing the entire gearbox.

Question about replacement

Dealers, unlike service stations, do not repair. They immediately send the CVT to the Nissan X-Trail to replace it. If it's under warranty then it won't cost anything. If not - new unit will cost a large amount.

Before surrendering to the mercy of car dealers, you can independently diagnose the CVT. You will need tools:

  • a set of keys (ring and open-end);
  • screwdrivers with a hammer;
  • clamps.

Before starting work, it is worth photographing the structure. This may help in further assembly. Boxes and jars for unscrewed nuts and bolts will also come in handy.

Visual diagnostics of the variator

Having studied each element of the checkpoint, you can understand why it does not work correctly:

  1. Remove the side cover and tray. There are special magnets on the pallet that keep debris and metal shavings from the variator. If there is a lot of it on the magnets, then you can limit yourself to replacing fine and coarse filters.
  2. Shafts and pulleys. First remove the shafts, then the belt. We evaluate his condition. If it is worn out, then it needs to be replaced. This is much less costly than new variator. If the cones are not scuffed, then the problem may lie in the bearings.
  3. The rumble in the operation of the variator appears just because of the backlash in the operation of the bearing. It can be removed from the unit with a special puller. It won't be hard to replace with a new one.
  4. The fuel pump is located under the torque converter cover. The differential and transmission pair are also installed there, which must be removed in order to remove the pump. If it is changed, then together with the drive chain.
  5. Rinse and dry all removed parts before reassembly. Rubber parts should be replaced immediately with new ones.
  6. It is necessary to assemble the elements in exactly the reverse order, follow right position box lock pins.

After assembly, check the gearbox:

  • start the engine;
  • check the inclusion of each range;
  • making a check-in.

If everything is installed correctly, the variator should work without extraneous noise and jerks.

More than ten years have passed since CVT transmissions ( further - CVT) began to be installed on Japanese cars manufactured by Nissan. But time does not stand still and progress, too. More and more motorists prefer vehicles with CVT. If you decide to purchase the X Trail, it is better to read the reviews of the owners on the net right away - you will learn a lot of new things.

Type of variator and resource of its work

On the SUV Nissan X-Trail can be installed in one of two types: RE0F06A or RE0F10A (JF011E). The latter are installed on the Nissan X-Trail and Qashqai J10. What is the difference between these types of CVTs? First of all, it's a big technological process during the production of the mechanical part.

SUV Nissan X-Trail

An improved version of the CVT (RE0F10A) differs from its predecessor in that the CVT pulleys are lighter, and the drive pulley has become a single piston. The company's engineers increased the pressure in the drive pulley circuit to 60 kg/cm. Note the improved external frequency of processing, which reduces the likelihood of transmission fluid adhesion and foaming.

The range of gear ratios was expanded in the system, the hydraulic control system was completely redone. To reduce losses, the pressure is adjusted on the driving and driven pulleys independently of each other. Prior to this, pressure adjustment took place on both pulleys. In the structure of the unit appeared chain drive as a result of the transfer oil pump into the tray.

User manual

As a result of the increased pressure, the temperature of the transmission fluid also increased. Therefore, the automaker's employees equipped the CVT system with an air cooling radiator. At the same time, the engineers added an oil heater. For what? When the driver starts the engine, the temperature, of course, does not match the operating temperature and the loads are also too high.

In such cases, the car owner believes that the transmission can be warmed up by pressing the gas pedal, but in this case the steel chain will rub against the cones and scratch them. And this will lead to a break in the circuit, but before that, metal dust from it will clog the system.


X-Trail car interior

The problem is not that the employees of the manufacturing enterprise, having nothing to do, decided to add more “hemorrhoids” to the car. It's just that domestic motorists mostly ignore the operating instructions from the manufacturer. It is enough to warm up the car to a safe temperature before driving (20 degrees Celsius) to prevent the elements from rubbing against each other. Accordingly, the likelihood of metal chips in the variator will decrease.

If you start the engine in winter

In the cold season, the engine warms up at idle (at neutral speed). If on the street subzero temperature, then the box will not warm up in neutral, as a result, it will have to be warmed up while driving. Of course, at a cold checkpoint it will not be possible to immediately go in the usual mode. There is a trick for this, which you could read about in the operating instructions for the vehicle.

Extract from the instructions: to warm up the CVT automatic transmission, start the engine, and with the brake pedal depressed, switch the speed to “D” or “R” mode. You need to hold the gas pedal and let the car run - this will warm up both the engine and the gearbox.

In the Nissan X-Trail, it is important not to run an oil change. The service life of the transmission fluid should not exceed 60 thousand km, but if you do not follow the operating rules, then it is better to change the ATF every 50 thousand km. Note that after changing the fluid using a scanner, you need to reset the oil aging counter. Otherwise, the pressure in the system will be non-standard and the resource of the variator will be reduced. To check how much transmission fluid is in the box, you need to use the dipstick.


CVT from Nissan X Trail on a pallet

Common breakdowns and methods for their elimination

Here is a list of symptoms that indicate abnormal CVT operation:

  • the car starts to slip on a flat road (without dirt and snow);
  • On the instrument panel of the X-Trail, the power-on lamp lit up emergency mode gearboxes;
  • the car slows down, while noise is heard from the box;
  • speed does not switch or switches with difficulty;
  • the power of the car disappears (when you press the gas pedal, the engine hums, as if in neutral);
  • vibration of the box (systematic or periodic);
  • when switching gears, the car starts to twitch, troit.

Noise

A common CVT failure is bearing failure. If they have already worked out their resource, the driver will hear noise or hum from the box. Such a problem occurs no earlier than with a run of 50 thousand km. How much is it? Replacing elements at a service station will cost no less than 35 thousand rubles (about 10 thousand hryvnias).


Disassembled CVT Nissan X-Trail

There are a number of reasons why bearing noise occurs. This may be the ingress of wear products into the variator system. In this case, you should not hope for two oil filters with a magnet that your CVTs are equipped with. Because they won't prevent metal dust from getting into the transmission fluid.

Some "craftsmen" advise to reduce the frequency ATF replacements up to 30 thousand km to avoid destruction and increase the service life of bearings. But, early fluid replacement (after 30 thousand kilometers instead of 50 thousand) does not affect the life of the bearings.

Loss of power

If there is a problem, then you have never changed the oil in the automatic transmission or have done it for a long time. Then you need urgent replacement liquids with a complete flushing of the system. It is important here to get rid of all wear products in the variator, otherwise the car will lose “traction” on the road from time to time. How much chips and dust in the gearbox, you can see the liquid draining from it.

Emergency mode

First, check if there is oil in the car. There may have been a transmission fluid leak, and its absence in the automatic transmission will lead to full release failure of the unit. Then you have to shell out a tidy sum for the purchase of a new CVT.

Jerky riding

If jerks are noticed while driving at a constant speed, then this may indicate another problem. In particular, for one kilometer of the road, the car twitches 1-2 times for no reason. These jerks are felt while driving in cruise control. Usually there are problems with the hydraulic valve, which are best solved at a service station with specialized equipment. How much the repair will cost depends solely on the type of damage.

Where to buy and how much?

As for the purchase of new CVT JF011E models, of course, it is better to do it with official dealer Nissan in your city. It's practical, but expensive. But how much does it cost? Not every car owner is ready to shell out 140 thousand rubles (about 35 thousand hryvnia) for the purchase of a new unit.

Naturally, you can buy a Chinese-made transmission at automotive market. It will cost about half as much, but it all depends on the region. Medium market price such units is about 70-90 thousand rubles (about 18-20 thousand hryvnia). Well, their working resource may be less. And maybe more: Chinese production- this is still an unpredictable thing, as lucky as anyone. And keep in mind - buying a CVT from a dealer, you have a guarantee for it, which cannot be said about fakes.
