Nissan Juke when to change the oil in the variator. Variators (CVT) Nissan Juke F15. Selection of materials for work

Nissan Juke is a popular Japanese SUV, one of the most fashionable and unusual cars in terms of design. It is recommended to regularly service this car, and thereby be confident in its reliability. So, one of the important maintenance procedures is changing the oil in the box. This procedure does not require professional skills and therefore can be carried out regularly to reduce the load on the engine. In addition, the performance of the variator has a beneficial effect on fuel efficiency. This article focuses on changing gearbox oil using the example of a Nissan Juke with a CVT. Important nuances and parameters of the liquid are presented to the attention that should be remembered during such an important procedure.

Replacement schedule

For the first time, the oil in the Nissan Juke gearbox is changed after 60 thousand kilometers - this despite the fact that the warranty period of the variator can reach 180-200 thousand kilometers, given the favorable operating conditions. If the car is often used in difficult conditions, for example, it often drives on dusty roads, then the replacement interval will have to be reduced to 30-40 thousand kilometers. In any case, the shorter the interval, the more reliable it is for the power plant and transmission.

Oil change nuances

The procedure for changing the transmission fluid in the Nissan Juke variator is carried out in accordance with the required parameters. Please note that the most reliable and durable is factory oil, which was poured into the checkpoint at the factory. This is the original grease, and the next time it is necessary to fill it. If this is not possible, you should select a fluid with parameters similar to the original grease. In any case, sooner or later an oil change will be needed. Let's highlight the main signs indicating the need for this procedure:

Vehicle slip
Noises and vibrations in the operation of the gearbox
Sudden drop in motor power
From time to time, the engine stalls, it is not possible to move normally
Impossible to drive fast enough as the dynamic parameters of the Nissan Juke allow

How much to fill

The recommended volume of fluid for the Nissan Juke CVT is three liters. This is the minimum volume at which oil starvation can be prevented. In addition to changing the lubricant in the variator, during this procedure it is also advisable to replace the oil filter, which is considered disposable. It is worth purchasing two cans of oil - so that there is a margin in case of additional liquid topping up.

Sequence of work

The car is installed on an overpass. First, you need to warm up the engine so that the oil reaches its operating temperature. It is believed that the hot liquid will pour out much more, and together with mud deposits and metal shavings
We unscrew the lid of the pallet, drain the old liquid into a prepared pallet. This process takes about 30 minutes.
Screw the sump cover back on, and move the container with the old oil to the side
After draining the oil, we proceed to the most important procedure - filling in new oil. To do this, we find the corresponding filler hole in the engine compartment, and fill it with fresh liquid, periodically checking its level
Start the engine, idle for a few minutes. At this point, you can work in the gearbox in several positions to allow the grease to spread to all components of the variator.
Stop the engine and check the fluid level again using a dipstick. If the filled oil is not higher than the maximum mark on the dipstick, then the process of changing the fluid in the Nissan Juke variator has been successfully completed.

Output

It is important not only to change the oil in a timely manner, but also to choose only a high-quality lubricant that is approved by Nissan. In this case, you should be guided by the viscosity and tolerance parameters specified in the operating instructions for the Nissan Juke, and according to them, you should already choose the appropriate oil for the Nissan Juke gearbox.

Often, owners ask themselves the question of when and when the oil is changed correctly in the Nissan Juke automatic transmission? The car is equipped with an improved version of the "automatic" with a variator, the period of the mixture renewal depends on the characteristics of the operation and the mileage of the vehicle.

Transmission oil change interval

According to the manufacturer, the Nissan Juke transmission is designed for the entire life of the car without the need to interfere with the lubrication system of the unit. The domestic climate, roads and driving nuances make their own adjustments. Experts recommend changing the transmission oil in the automatic transmission of the Nissan Zhuk car after 50-60 thousand kilometers.

In a planned manner, the level of the variator working fluid is monitored every 15,000 km. This makes it possible to avoid unexpected breakdowns. Action is required if:

vibrations, extraneous noises and knocks appear in the automatic transmission;
motor power decreases;
the reaction of the box to the driver's commands becomes worse.

If the mixture is below the recommended level or has exhausted its resource, the channels of the hydraulic block, the plunger become clogged, causing oil starvation. Due to increased friction, the discs and valve body wear out, the temperature rises, the pistons and the clutch drum heat up. These factors lead to the need for unscheduled repairs or replacement of the Nissan Juke automatic transmission. It will take three liters of grease to renew the stock. It is recommended to use the original CVT Fluid NS brand.

To accurately find out the volume of the liquid to be poured and drained, the car is placed on an overpass or pit, after warming up the engine (the remains will drain faster from the pipes and mating units). The lubricating composition at the outlet has a high temperature, in order to avoid burns, PPE should be used.

Self-change of oil in automatic transmission Nissan Juke

The operation to update the working fluid can be done by hand. On boxes with high mileage, partial replacement is preferable, since the process occurs gradually.

In this case, you need not just drain the old one and fill in the new composition. It is necessary to travel some time between stages. At the service station, changing the oil in the Nissa Juke gearbox in this way will stretch out, it will take a lot of lubrication, time and money. Use the same brand filled at the factory.

Draining old oil from the tank

After placing the car on an overpass or pit, unscrew the drain cover and a measuring tube, through which the level is controlled. It is an iron element screwed into the pallet. If more fluid enters the automatic transmission than necessary, the excess will go through this tube. After dismantling the pallet, a little more mining will be merged (3-4 liters). All parts are washed, cleaned and assembled back.

To dismantle the assembly, you will need to remove the front left wheel and wheel arch liner. The rest of the procedure is simple. Unscrew a couple of bolts by 10, remove the tube, remove the old automatic transmission filter, mount the new element in the reverse order.

Filling in new oil

The composition is poured through a special plug, which acts as a probe. Then Nissan Juke is raised on a lift, the engine is started, warmed up, each mode is turned on for 4-5 seconds until the automatic transmission warms up to 45 degrees. Unscrew the plug without touching the measuring tube and wait until the oil begins to come out drop by drop. After a day, the procedure is repeated without dismantling the pallet and replacing the filters.

Select the "Data Monitor" section in "Consult".

Complete replacement of transmission fluid in automatic transmission

This procedure on the Nissan Juke includes the obligatory flushing of the variator. After draining the mining, screw the plug and open the filler hole. A special flushing compound is filled, the engine is started. All gears are smoothly switched, with a two-second delay.

The engine is muffled, the residues are released through the drain. Unscrew the crankcase of the variator, remove dirt. The surface of the compartment is cleaned with acetone, after which the element is mounted in place. Fill in new grease, check the fill level. After the first filling, this indicator is periodically monitored, adding liquid if necessary. This is due to the fact that on the first trips, the mixture will be distributed through the connecting channels and nodes.

Conclusion

Timely oil change in the Nissan Juke box with a variator helps prevent many problematic moments typical for automatic transmissions. Before starting work on your own, you should take into account your own experience and skills so as not to aggravate the situation. If you have doubts about your abilities, it is better to entrust the work to specialists.

In our time, CVT transmissions are becoming especially popular. The high demand around the world for them is mainly due to technical progress - this type of transmission is the most modern development.

The Russian market is just beginning to master CVT gearboxes - at the moment, not many car owners will be able to say exactly what types of oils need to be used in CVTs, in what volume and after what period of time to replace them. To find out to clarify the answers to the questions posed, it is necessary to approach in detail the study of the variator box used in the Nissan Juke.

Features variator Nissan Juke

A variator-type gearbox is an important element of the car system, which is distinguished by the use of high technologies in its creation. Such a complex type of gearbox allows you to correctly distribute the motor load, while ensuring the most comfortable movement of the vehicle, excluding sudden jerks and dips. In addition to these properties, the variator is able to economically consume fuel.

All Nissan cars have CVT type gearboxes, which are produced at the Japanese plant Jatco. This industry provides variators for most of the world's car manufacturers, while providing a guarantee for the first 120 thousand kilometers (with an initial resource of 180-200 thousand kilometers). However, this option is only possible if the vehicle is properly maintained. First of all, this concerns the replacement of the lubricant composition, which is made on time.

For a variator gearbox, oil starvation can be a disastrous process, since its structural part consists of a large number of moving elements. If their lubrication is not high-quality and timely, the friction between the parts will increase, which will negatively affect the entire structure as a whole. In addition, a properly selected lubricant can prevent slippage of parts of the gearbox structure. In the case when the oil is of poor quality, and there is not enough lubrication, the operation of the entire gearbox system is disrupted.

Changing the oil in the Nissan Beetle variator can be done both at a specialized point and with your own hands. This procedure does not have any particular difficulties, and it is quite within the power to cope with it even for a driver without special skills. In addition, most of the information can be found on the Internet, as well as many videos that detail how to change the lubricant in the variator.

According to the technical regulations, the oil level in the Nissan Juke variator must be measured every 15 thousand kilometers (this corresponds to scheduled maintenance). However, changing the oil in the variator is only necessary if absolutely necessary, since the manufacturer provides a guarantee for a long service life of the structure and fills in oil in accordance with it.

Despite some technical flaws, CVTs are considered to be the most reliable types of gearboxes in comparison with automatic transmissions. However, over time, negative changes can occur in the operation of the box - they will tell you that the gearbox needs to be replaced with a transmission fluid. It is especially worth paying attention to:

Vehicle slippage;
Abnormal gearbox vibrations;
Deterioration in vehicle power;
Deteriorated gear shifting.
In the case when such factors appear periodically, it is worth thinking about changing the transmission fluid.

The process of replacing the transmission fluid in the Nissan Juke gearbox

The volume of lubricant in the Nissan Juke gearbox is 3 liters. It is this volume that is quite sufficient to exclude engine oil starvation. When changing the lubricant, you can also take care of updating the filter, since a dirty filter element creates certain problems for the correct distribution of the oil fluid.

To start the process of changing the gear lubricant, you need to decide what kind of oil you need for the job. For Nissan Juke, the best option would be the original Nissan CVT Fluid NS-2. It has high lubricating properties and prevents the gearbox from malfunctioning. For the full volume, two canisters will be sufficient.

For a successful oil change in the variator, you should prepare the following tools:

Spanners;
Screwdriver;
Tank for draining waste material;
Rags;
Syringe (or funnel);
Gearbox pallet gasket.

The process of changing the oil in the CVT is as follows:

First of all, you need to install the car on an overpass or above a viewing pit in order to provide access to the variator;
Next, you need to carefully unscrew the pallet cover;
The next stage is the removal of the old waste liquid;
Then you need to remove the container with the used oil and screw the plug;
The next step is to open the hood to find the filler hole;
Fill in oil, then check its level;
Start the engine and let it run for a few minutes, periodically changing gears;
Subsequently, you need to check the oil level again and, if necessary, add fluid.

After that, you need to make a short trip, and then check the oil in the variator again. Next, you should periodically check its level to avoid oil starvation.

Replacing NS-2 oil with NS-3, features and consequences

05.10.2017

The fairly popular NISSAN model, along with the QASHKAI J10, received a 1.6-liter (HR16DE) version with a non-turbo engine, probably one of the most unsuccessful transmissions in terms of minimum resource.

On average, the transmission of the same QASHKAI J10 with a two-liter MR20 engine manages 250,000 km without problems, which is not often found in modern cars.

But with a 1.6 liter engine, the designers made one trick, which turned out to be fatal, and the rare CVT JF015 (RE0F11A) reaches 100,000 km. Consider this fatal constructor error.

The whole problem was initially in economy and ecology.

A very small engine is installed on the car, neither power nor moment of which is in any way enough for driving in city mode. To give at least some accelerating dynamics, an automatic two-stage transmission was integrated into the box with a gear ratio of 1.8 in first gear to 1 in second.

In addition to the usual continuously variable variator with a gear ratio of 2.20-0.55, after the pulleys with a conventional CVT belt, a two-stage automatic transmission is installed, the planetary gear of which is visible in the photo.

The design is very delicate, there is practically no safety margin, and the main problem is that the sun gear breaks off from the drum.

Thin metal, high revs - all this leads to such consequences.

Initially, the idea was good: light pulleys rotate with engine speed, and then the lack of engine power is compensated for by expanding the gear ratios - but not due to the size (diameter) of the pulleys, but due to the stepped gearbox. Thus, with compact dimensions, a transmission ratio of 4 can be obtained at the start of the movement. Shifting of a stepped transmission occurs at 60 km / h, it is less noticeable, like a jerk when the torque converter is locked at 20 km / h, and is more calmly transferred by a weak motor, which by the time of switching 2nd gear has already been spun up to high revs. But in life, such a car constantly drives at high engine speeds, and therefore, transmission elements. All this leads to its premature failure.

The oil used in it played a very important role in this. Initially, this transmission was not only innovative in this - it removed the so-called "STEP MOTOR".

This electric machine moved the valve stem responsible for changing the gear ratios in the CVT, in other words: "it changed gears (virtual)". The main disadvantage of transmissions, where the gear change was controlled by the command of the STEP MOTOR block, is their inertia, as well as inaccuracy of control associated with the inability to determine the position of its rod in some transient modes. New types of transmissions do not have such a device (including the JF015). Here, gear control is implemented by linear solenoids. The inertia of such a system is an order of magnitude lower, the control accuracy is higher. But there are also disadvantages. First of all, technologically it is made with smaller gaps and more fluid oil.

(lower viscosity). Old NS-2 oil is no longer quite suitable for such CVTs, and this is especially true at low temperatures. High viscosity leads to a low pumping rate - oil flow in the thin gaps of the control valves, the cross section of which has become even smaller. Recovering themselves, the engineers released a new NS-3 oil with different characteristics, but O Most of the cars were sold with NS-2s and things got even more interesting. In an effort to reduce damage to the transmission, NISSAN conducted revocable

(service companies), which our dealers, as always, ignored. This resulted in massive damage to all transmissions on JUKE and QASHKAI with 1.6 HR16DE engines and a CVT such as JF015.

Due to the general confusion and slovenliness, dealers began to flood the NS-3, and this led to jerks in the CVT "cold".

In October 2013, a circular was issued obliging to replace the software of the CVT control units when replacing the NS-2 oil with NS-3.

Excerpt from it.

Then, in January 2014, due to confusion in the types of fluids used, NISSAN issued a second circular, where it explained where you can change NS-2 to NS-3 without consequences.

But during operation, it turned out that on NS-3 CVT JF015 oil, the belt begins to slip during heavy traffic, which also leads to damage to the transmission. And all software replacement procedures in 2013 turned out to be wrong. The CVT control programs contained errors that were eliminated only in 2017, and finally they released modified firmware for the blocks.

Below is a table of modified software for CVT control units for J10 and F15. At one time, the owners of XTRAIL and TEANA also had to reprogram the blocks.

Conventionally, for today, whatever firmware of the CVT unit you have, in order to save the transmission resource, you need to replace the oil with NS-3 and reprogram the CVT unit if your firmware differs from the tabular one.

To do this, you need to check the unit firmware version with a scanner (as in the photo) and compare it with the table. In this example, we see the firmware version 1KA0E (the first digits for all CVT units are the same-31036), and we look at the table - there is an update. After reprogramming (with new NS-3 oil), reset the learning (accumulated parameters) and carry out a road test to teach the transmission.

On the corrected control program, the transmission works much better, according to the owners' feedback, the dynamics are better, and the fuel consumption is lower. Before changing the CVT control program, we always change the oil to a new (fresh) one. The fact is that after reprogramming, the accumulated training data is erased and on the old (dirty oil) training is incorrect, especially if the oil has exhausted its resource and its parameters are far from tabular due to aging.

Regarding pouring non-original oils into the CVT and the consequences, it has already been said more than once. We look at the parameters of the kinematic viscosity of NS-2 and NS-3 oils in the tables below. We are interested in the conditional viscosity at a temperature of 40 degrees and 100.

NS-3

It seems to many that the parameters are insignificant and what's the difference, you can fill in another non-original oil or even "don't understand what". But in reality, even such a deviation in viscosity led to jerks at temperatures below zero and belt slippage at high temperatures and loads.

What the engineers wanted and what they failed.

Initially, the problem is in the climatic conditions and the operation of the machine. Drivers do not warm up their cars and start driving immediately. In these CVTs, the oil is heated by the engine coolant, when it warms up, it heats the oil in the CVT. But no one heats the engine because of the economy of gasoline, the oil is too thick, it is poorly pumped in thin gaps, jerks occur.

Reducing the oil viscosity for the type of transmission led to a drop in viscosity "hot", the belt began to slip under load. In fact, NS-3 is made for drivers who do not want to warm up their cars before driving, because when fully warmed up to 100 degrees, its viscosity is lower and this led to belt slippage and damage to the CVT.

The new CVT control program precisely increases the pressure at high temperatures of NS-3 oil, compensating for its low viscosity programmatically. Yes, there are countries and regions with a warmer climate where the problem of warming up the oil in a CVT is not so urgent, but in our country it does not just go away. The car needs to be warmed up. This applies to all cars with any type of transmission - there must be an operating temperature. For cars with a START-STOP button, there is a good technical solution - we set autostart by activating the functions of the native key fob - pressing the door close button three times in a row: the engine starts automatically. All cars equipped with auto-start or warmed up by the owner met with mileage and under 300,000 km without problems in CVT, these are 2-liter engines and above.

conclusions

In CVT JF015, it is imperative to change the oil to NS-3 and reprogram the unit with retraining and road test. In the old type of transmission, where STEP MOTOR is used, it is better to leave the NS-2 and warm up the car. This applies to XTRAIL T31, QASHKAI J10, TEANA J32 - they were revocable for replacing the control program, similar to JUKE, and many of these procedures were carried out, including ours. For all new cars, such as XTRAIL T32 or QASHKAI J11, the body (from 2014) - only NS-3 and reprogramming of the unit. There is no point in reprogramming the blocks without changing the oil to fresh, it doesn't matter NS-2 or NS-3. On old, dirty oil, the training of pressure modulators is incorrect.
