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 a mileage of 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 for 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 fine 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 started to get 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 firmware version of the unit 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.

It has been said more than once about pouring non-original oils into the CVT and the consequences. 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 of viscosity led to jerks at temperatures below zero and slipping of the belt 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 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 the START-STOP button, there is a good technical solution - we set the 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, no matter NS-2 or NS-3. On old, dirty oil, the training of pressure modulators is incorrect.

The main feature of the Nissan Beetle is that a variator is installed on almost all of its models - a new gearbox, an improved version of the machine. It is necessary to change the fluid in the variator in the same way as any filling fluid in the car.

Timing of oil change in automatic transmission Nissan

Changing the oil in the automatic transmission on the Nissan Beetle, according to the manufacturer's manual, is not required. The original grease, filled at the factory, is quite enough for the entire operational life of the machine. However, taking into account the peculiarities of our roads and climate, a periodic change of lubricant is necessary every 45-60 thousand kilometers.

According to the regulations, every 15,000 km it is necessary to check the fluid level in the variator in order to avoid the appearance of some negative points.

Signs for replacement:

slipping of the car;
the presence of vibrations, knocking and noise in the box;
decrease in engine power;
the gearbox reactions to the driver's movements worsen.

If there is not enough oil in the Nissan Juke automatic transmission or it has reached its end of life:

the plunger and channels of the valve body are clogged with particles, causing an oil deficiency;
the temperature rises and the discs of the box are erased due to friction;
the clutch drum, pistons and discs overheat and burn out;
the valve body wears out.

The filling volume of the grease is 3 liters. This is exactly how much is needed to prevent oil starvation of the checkpoint on the Beetle and update the fluid in it.

Oil change in automatic transmission on Nissan Beetle

List of required tools for changing oil in automatic transmission in Nissan Juke:

canister of new NS-2 or NS-3 oil - it is this lubricant that is filled in by the factory, and you can safely pour it in;
box pallet laying;
set of wrenches;
new filter;
new ring for the drain plug;
waste liquid container;
rags;
rubber gloves;
clean rags.

It is preferable to take original oil for NISSAN JUKE - NS-2, NS-3 or Nissan SVT Fluid.
Before starting work, the car should be placed on a repair pit or overpass. An oil change in an automatic transmission in a Nissan Beetle occurs on a warmed-up engine - this contributes to the rapid drainage of mining from all channels and units of the box.

It is important to take into account that the liquid at the outlet is hot, and in order not to get burns, you should take care of your safety: overalls and work with gloves will prevent unwanted contact of the oil with the body.

Partial oil change in an automatic transmission

Do-it-yourself partial oil change in a Nissan Beetle automatic transmission is a simplified scheme of work, when the lubricant is drained and poured, without cleaning the sump and flushing the gearbox.

Replacement is carried out in the following sequence:

Unscrew the drain plug and drain the old oil into a container.
Unscrew the pallet of the box and peel off from the sealant.
Replace the filter or rinse and reinstall it in its seat.
Find magnets at the bottom of the pallet to collect chips and dust, clean them with a rag.
Rinse the pallet and dry it, and then reinstall it.
Replace the pallet gasket.
Replace the drain plug gasket and tighten it.
Pour new product through the inspection hole by pulling out the dipstick.
Check the lubricant level on the dipstick on a cold one.

Tighten the filler hole and drive 10-15 km, checking the level on the hot automatic transmission.

Complete oil change in an automatic transmission

A complete oil change in an automatic transmission on a Nissan Juke includes flushing the variator - one of the mandatory procedures in full operation.

After the liquid is glass, it is necessary to tighten the drain plug and unscrew the filler hole.
Fill with special flushing agent and start the engine.
Without jerking, we switch all gears in turn, lingering for a couple of seconds on each.
Stop the engine and drain all fluid through the drain.
Unscrew the crankcase and drain off the remaining mass.
Clean the crankcase surface with acetone and reinstall.
Add new oil in the same way and check the level.

On this, independent work on a complete change of the lubricant in the automatic transmission Nissan Zhuk is over.

After updating the fluid in the gearbox, it is necessary to periodically check its level and top up. Since, after the first trips, some of the oil is distributed over the nodes, channels and gearbox components.

Like any other component of the automotive system, the Nissan CVT needs regular maintenance, which consists, first of all, in the timely oil change. You can change the fluid yourself, but you will have to carefully prepare for this.

CVT maintenance

A variator transmission (CVT) is a high-tech component of the automotive system. It has a rather complex structure and performs an important function: it correctly distributes the load on the engine, providing a comfortable movement, without jerks and failures, as well as fuel economy.

Nissan cars are equipped with variators from the Japanese Jatco plant, which produces variator boxes for almost all car brands in the world. The Jatco factory warranty is 120 thousand km of run, and the real resource of the units reaches 150-200 thousand km. This is possible only if the device is properly maintained, mainly - timely oil change.

Oil starvation is the main enemy of the variator. Its design contains many moving parts that need high-quality lubrication to reduce friction. In addition, the specialized CVT oil prevents slippage of the gearbox elements. If the lubricant is insufficient or of poor quality, the operation of the unit is disrupted.

How often do you need to change the oil?

Oil change in Nissan variators, as a rule, is performed during routine maintenance of cars. From the service regulations it follows that it is necessary to change the fluid in the box every 60 thousand kilometers. However, we recommend that you replace it more often - after 25-30 thousand km.

It is almost impossible to independently determine the level and quality of the transmission fluid, since there is no corresponding dipstick in the variator gearbox. Therefore, the most reliable way is to count the mileage. As soon as the mileage traveled reaches the figure of 30 thousand km, it is worth stopping by the store and buying oil for the Nissan variator.

Oil selection

As already mentioned, the lubricating fluid in the variator box performs another function - it prevents slippage of working parts. Therefore, a special synthetic oil has been developed especially for variators.

The Nissan car plant produces branded products for its cars, which are recommended for use in various car models: NS-1, NS-2, NS-3. The number in the title indicates the generation of the liquid (first, second, third).

In the catalogs of auto parts, these products are presented under the following articles:

Manufacturer	Detail number	Part name
Nissan	Kle5000004	Transmission oil CVT for variators NS-1 4l
Nissan	Kle5200004	Transmission fluid CVT FLUID NS-2 mineral, JP 4L
Nissan	Ke90899931R	Transmission fluid N-CVT AT-MATIC D FLUID JP 1L
Nissan	999MP-NS200P	Transmission oil NISSAN CVT NS-2 1L
Nissan	Ke90999943	Transmission oil NS3 5L EU
Nissan	Kle5300004	Liquid nissan cvt fluid ns-3 4 l (replacement for NS1 and NS2)

Before you buy oil for a Nissan CVT, you should find out what kind of fluid is in it. The manufacturer strongly discourages mixing different types of products, since they are not interchangeable.

If you are in doubt about which oil to pour into the Nissan CVT, the best solution is NS-2. This fluid is suitable for Nissan Juke, Qashqai, Teana, X-Trail and others.

Instructions for changing the oil in the variator

It may take up to 10 liters of new oil to completely replace the transmission fluid. During operation, it is recommended to use a diagnostic device (to measure the temperature of the working fluid and reset the counter showing its condition).

How does the oil change in the Nissan variator do it yourself:

Having measured the operating temperature of the liquid, remove the plug and drain the old oil.
A plug is installed and a new liquid in a volume of 3 liters is poured through the control hole.
After installing the control plug, start the engine and turn on all gears in sequence for about 5 seconds.
After the working fluid has completely warmed up, the motor is stopped, and then the flushing procedure is repeated.
Fill in new 3 liters of oil, change gears with the engine running, and then unscrew the check plug to drain excess fluid.
If the liquid does not flow out, add 0.5 l of oil.
Reset the counter readings by diagnostic equipment.

During the operation of any car, it is always necessary to carry out a daily inspection of the car, at least for the absence of oil and fluid leaks from the car systems. But when buying a new car, each driver has questions about where and how to check the oil or fluid level of a particular system or unit. Of course, you can look at the instruction manual, but it is not always visible and clear where it is located. So, further we will dispel the myth that the transmission fluid level in the Nissan Juke CVT cannot be checked. It is possible and necessary. Let's remind a little that the Xtronic CVT M6 variator is installed on all-wheel drive vehicles. It is important to remember that before checking the liquid level, it is necessary to carry out a number of actions, according to the Manual, namely:

The procedure for checking the fluid in the variator Nissan Zhuk

1. Since the liquid before checking the level must be 50-80 C, for this you need to drive through the city. It will take about 10 minutes for the fluid in the variator to warm up to 50-80 C at an ambient temperature of 20 C.

2. After that, it is necessary to park the car on level ground. And apply the parking brake.

3. With the engine running at idle, pressing the brake pedal, move the selector lever through all positions.

4. Next, open the hood and look for the dipstick, and then remove it from the pipe. The dipstick is located between the battery and the engine. Figure 1 shows how it looks. To remove it, you must press the latch and release.

Figure # 1

5. Further, the verification procedure is as follows. It is necessary to take non-fibrous paper (rags cannot be used!). Wipe down the dipstick. Insert the dipstick by turning it 180 degrees from the original installation position and push it all the way into the nipple. Then you need to move the selector lever to the P or N position and make sure that the fluid level is within the specified range. Figure # 2 shows the minimum point of the liquid level.

Figure # 2

6. After checking the liquid level, place the dipstick in its original position, turning it until it locks.

Checking the condition of the variator fluid on a Nissan Juke

When checking the fluid level, it is imperative to pay attention to the condition of the fluid and, accordingly, draw further conclusions and find the cause that contributes to the malfunction of the variator.

Fluid condition	Cause	Corresponding procedure
Varnish-like (viscous state)	Change in the chemical state of a liquid due to exposure to high temperatures	Change CVT fluid and check the transmission control unit and vehicle for any faults (wiring harnesses, coolant lines, etc.)
Milky white or cloudy	Water in the working fluid	Replace the variator fluid and check for possible water ingress into the variator fluid
With a lot of metal particles	Excessive wear on friction surfaces	Change the working fluid and check the operation of the variator

Also, when checking the level, you must pay attention to the smell of the liquid. It shouldn't be burnt.

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 the oil in a gearbox 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.

Selection of materials for work

Original transmission oil Nissan CVT Fluid NS-2
Set of wrenches
Tools, including a screwdriver
Towel, rags, rubber gloves
Syringe
Sealing gasket
New oil filter
Waste liquid drain pan

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 and idle for a few minutes. At this point, it is possible to 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.
