To change the oil in the variator, you need a little:

First of all, you need the oil itself, for my CVT it is NS-2. I took two cans of 4 liters each, there was one incomplete can left, because consumed approximately 5.2 liters. In addition, you needed a container to drain the used oil, a stationery knife, a 19 wrench, a plastic bottle with a hose (1 cm diameter), gloves and electrical tape.

I used a flyover, but you can do without it.I drove onto the overpass, opened the hood, pulled out the variator probe

who does not know - there is a latch on the probe on the side of the handle, you need to press it with something like a screwdriver, I press it with the key from the office :) Then we take this:

and unscrew this

After the first turn of the plug, you can unscrew it with your fingers, placing a container underneath to receive oil. I had two of them :)

Who does not know - the oil is hot and, as you can see, it is already very dark. In order not to bother with the volume of new oil poured in, we make marks on the containers with used oil. I scribbled a mark on the bottles with a clerical knife. If you want the marks to be clearly visible in the photographs, take white gouache with you :) We carefully pour the used oil into a 6 liter jar and later take it to comrades who have a boiler working on mining. At the bottom we find this:

do not forget to pay attention to the presence of a sealing washer on this. If everything is in place, we screw it back where it was, tighten it without fanaticism.

Then we do it like this:

and like this:

Pour new oil into the already empty containers for used oil, exactly at the mark. You can't see it here, but the oil is green like Tarragon, but you can't drink it.

And here you can already see that the oil is green:

but you still can't drink :)

After all the oil is poured into the variator, the most difficult thing remains - we remove the pribluda with a hose, insert the dipstick into place, close the hood, collect empty cans in a bag, tie the bag into two knots and put it in the trunk - this is a gift to the nearest garbage can. Then we wipe the dust in the engine compartment with a cloth for another hour and get satisfaction from the work done, it looks like this:

Then we drive along the highway for 10 km, indulge in the SPORT button, do not listen to music, listen to the engine. We stop, drive the gearbox lever in all positions, leave it in the "P" mode, don't jam the car, get out, take out the dipstick and check the oil level in the variator. We are convinced that everything is fine, we sit in the car, drive further home to have dinner, listen to music on the way and plan in a couple of weeks.

Oil in the variator on the Nissan Tiida is poured into the box at the factory. It is extremely difficult to replace the oil fluid in the variator without special tools. Therefore, before the process, it is recommended to acquire the necessary tools, materials and skills.

When is a partial and complete oil change in the Nissan Tiida CVT required?

Partial oil change in the variator means only draining the fluid from the drain hole. The liquid inside the radiator, shafts and coupling will remain at the same level. Partial replacement of the car oil in the variator is carried out every 30-40 thousand kilometers.

Complete replacement of the car oil in the variator involves not only draining the fluid from the drain hole. Includes sump flushing, cleaning and replacing the entire fluid. Such a replacement is required every 60-80 thousand kilometers.

What kind of oil to fill?

It is recommended to fill the original oil into the Nissan Tiida variator Nissan CVT NS3... The required volume of liquid is 7 liters. If the owner of the car decided to change the fluid partially, then about 4 liters will be required. Additionally, you should change the fine filter.

The available option on the first generation Nissan Tiida is the original transmission fluid Nissan CVT NS-2. For a partial replacement for the variator of this machine, 2.8 liters of oil are required, and for a complete replacement, 5-6 liters of motor oil. Replace the clean filter element and rinse the other one.

Oil change process

Before you start changing the oil in the variator, you should prepare for work. There are two filters in the Nissan Tiida variator: fine and coarse filters. Fine cleaning is bound to change, since it is composed of paper material. The coarse filter can be changed or washed. Therefore, one or two filters should be purchased prior to replacement.

Additionally, the necessary tools and materials are prepared:

• A set of wrenches and hex keys;
• Screwdriver;
• Pliers;
• Jack;
• Syringe or flexible tube neck;
• Waste fluid container;
• Clean rags;
• Fresh oil.

Oil draining

Step by step instructions on how to properly drain the oil:

1. Park the vehicle on a level surface.
2. Unscrew engine protection (if equipped). Pliers, screwdriver and wrenches are used.
3. Unscrew the plug in the pallet. The amount of liquid that will drain into a canister or other container for waste liquid is 4-5 liters.
4. Screw the drain plug back on. Replace the rubber washer if necessary.

Cleaning the variator

Step-by-step instructions on how to properly clean the variator box:

Filling in new oil

How to properly pour new oil into the variator - step by step instructions:

1. After the drain plug is screwed on, it is necessary to pour oil through the dipstick. Use a syringe or funnel with a hose.
2. Fill in about 6 liters, then check the level.
3. Set the dipstick to its original position.

The oil change procedure in the Nissan Tiida variator is completed.

Starting the engine after changing the oil

The engine is first started immediately after changing the oil. This requires the selector to be in neutral. Warm up the engine, and then view the oil level (above the set mark).

After warming up the oil and checking the variator, carry out a test drive on the car for 10-15 kilometers. Then go back to the garage and check the fluid level again. If necessary, top up to the mark. The car oil level should be between the lower and upper marks (preferably as close to the upper as possible).

Machine control with automatic transmission is much easier than in designs with another device. But at a service station, changing the oil in the variator will not be the cheapest procedure. Some workshops refuse to do this work altogether due to the high complexity. This does not mean that you need to completely abandon the variator. It is easy to avoid such complications by carefully handling the system and changing the transmission fluid in a timely manner.

There are certain subtleties that must be taken into account when doing this job, including in Tiida.

1. Completely old oil cannot be removed from the automatic transmission without special equipment.
2. Only in new CVTs it is possible to remove old oil. This procedure is not desirable for older devices.
3. Tiid's and other brands' boxes require regular diagnostics.
4. It will take about 12 liters of new formulation to completely replace the grease with flushing. The old oil must be completely replaced by the new one. The proper result cannot be achieved without using a compressor or pump.
5. Partial replacement may not give the desired result. This is due to the fact that old fluids initially contain some amount of impurities.

How to make the right choice?

Nissan CVT Fluid NS-2 is a proprietary oil that is best suited to be replaced.

This composition is poured into the box of Tiida and other models even in the factory. You can buy oils from other manufacturers, but here the buyer himself chooses how much money he is willing to spend. Only expensive oils will ensure stable trouble-free operation of the unit.

Detailed instructions for working with your own hands

It is very difficult to achieve a complete lubrication change in the Nissan Trail automatic transmission without special equipment. Therefore, at home, such work can only be partial.

Of the tools for Tiida and other models, we need:

1. Rags.
2. Part with new filter for Nissan Tiida or other brands.
3. Crankcase gasket.
4. Container for draining waste grease, for 8-10 liters.
5. Jack.
6. New oil for 8 liters.
7. Keys set.

Description of the main stages

Better to take a short trip first, or warm up your Tiida to drain the oil better. It is recommended to use the classic version of the lift for all work. But overpasses with inspection pits are also suitable if this device is not available.

Fluid level in the variator box. Correct measurement

Many Nissan drivers face errors due to incorrect level measurement. Almost everyone thinks that you need to fill in the liquid as much as it was drained. But there are situations when there may be less new fluid. Most of the channels become airy after the waste fluid has been removed. Therefore, the lubricant does not get inside these structures.

The air is removed after a while. After that, grease begins to enter the channels. If there is too much liquid during this moment, it will simply foam. Which leads to even bigger problems.

To correctly check the liquid level, you must:

At first glance, it seems that it is easy and simple to check the lubricant level in a Nissan car. The car owner needs to be aware of several points: both high and low levels can be dangerous; if the value is too high, the lubricating characteristics deteriorate, foaming occurs.

Features of replacement in CVT transmissions from Nissan

Over time, manufacturers improve vehicle mechanisms. The trail was no exception. For example, on many modern models, including the Tiida. aging counters appeared. Such sensors cannot be replaced by putting something else in their place.

This kind of mathematical algorithm is put into the Nissan transmission control unit from the very beginning, even in the factory. Conventionally, fluid aging correction factors are introduced based on several parameters, including temperature, rpm and load. Thanks to this device, the filling interval of the new composition for Nissan is reduced, but the quality of the mixture does not deteriorate. In an approximate sense, this algorithm gives the driver an idea of \u200b\u200bhow long the train has been working with a high temperature.

The fluid in Nissan Trail or Tiida transmissions is now changed when the aging rate reaches 210 thousand. Usually, the procedure is prescribed during maintenance, examining the contents of the car. The liquid is not changed if its indicators are normal. But practice shows that even at 60 thousand, many structures require repair, or they need to be changed.

Engineers conducted a series of studies in which they found out the main causes of breakdowns.

1. Poor quality road surfaces.
2. Low qualification of the service personnel.
3. Low culture of operation of the Nissan Trail.

Each reason has a number of characteristics.

• The low culture of Nissan Trail operation is due to the fact that many drivers neglect the operating instructions. For example, engine warming up is ignored in winter. The engine cooling system helps warm up the compound in the CVT. But owners do not warm up their engine, citing time savings.

A huge load on the transmission units leads to deformations. Even the power steering suffers from this.

• Low qualification of the service personnel. Often, employees try to sell the car itself or their services as soon as possible. They don't care about the complications that are then passed on to vehicle owners when Nissan automatic transmissions fail. Many, on the contrary, try to prove that there is no change procedure at all, like a counter, an indicator of aging.
• Poor quality of road surfaces. Most of the problems arise at joints and waves. Because of this, oscillatory processes appear in the transmission. The oil film in the gap is destroyed. This also affects the design of the variator.

Compact Crossover Maintenance: Gear Lubrication

The drip tray in the car must be completely removed to access the largest filter. Typically, this part is protected from plastic in a Nissan automatic transmission.
The filter is protected by an iron casing, when it comes to the first generation variator. In the second generation, the protection is always plastic. There is practically no difference between these cases. But this does not mean that the parts are interchangeable. The details are similar to each other only in the sense that they are in one place, and the purpose is the same.

The presence of a fine filter is another detail in which the first generation of the variator differs from the second. The second generation variator does not have a filter in the pan. But the part has been moved to the radiator. The design is called outboard. But for the first generation filters, this part is in the sump itself.

There is usually a yellow strip along the entire perimeter of the variator. Not everyone knows what kind of part it is and what function it performs. This is a special cardboard spacer. It is recommended to be careful when removing it. If the part is not damaged during the dismantling process, it will serve almost forever.

Why change the transmission fluid at all?

This procedure is necessary for any vehicle and Nissan automatic transmission, even if the instructions say nothing. And, even if the liquid does not flow anywhere for a long time. Evaporation processes still occur in the system, due to which the amount of working fluid decreases. Because of this, automatic transmissions fail ahead of time, begin to wear out.
Therefore, it is recommended to check the total oil level in the automatic transmission every month. This must be done during scheduled maintenance on the vehicle. The presence of a characteristic smell of burnt, changed shade should suggest that the liquid must be changed.

Should you change the fluid in maintenance-free automatic transmissions?

The maintenance-free type of boxes also allows fluid replacement, just this process has its own characteristics. The fresh composition must be refilled as much as the used one was drained. It is necessary to measure the amount of liquid that has already been drained.

It is important to consider the property of a liquid to expand as it heats up. Therefore, it is necessary to fill in the substance when it is still cold. It is best to cool the box before serious manipulation begins. It is necessary to familiarize yourself with a number of requirements set by the manufacturer himself. It is almost always advised to use original solutions, but their cost is very high. For the gearbox, you can also select the composition of the universal action.

Gear lubrication: myths and reality

Output

Changing the lubricant is a fairly simple procedure that even for beginners will take no more than twenty minutes if all the necessary tools are available. It is recommended to carry out work every six months, or every fifteen thousand kilometers. This will ensure smooth operation in all elements of the system.

And a little about the secrets of the Author

My life is not only connected with cars, but also with repair and maintenance. But I also have a hobby like all men. My hobby is fishing.

I started a personal blog where I share my experience. I try a lot of things, various methods and ways to increase the catch. If interested, you can read it. Nothing more, just my personal experience.

Attention, only TODAY!

I decided, with the arrival of heat and a filter, to change the oil in the vario!
I took Idemitsu CVT Type N oil, read that it was in NS-2 cans. I took 8 bottles of 1 liter each with a price of 640 per liter.

I also ordered a pallet lining



I ordered a fine filter, I waited for it the longest - almost a month ... thanks to Emex that the filter was lying around in our city for a week ...



We need to replace: A knob and a ratchet A small extension (unscrewing the bolts of the pallet) Head for 19 (unscrew the drain bolt) Head for 10 (unscrew the bolts of the pallet and the coarse filter) Hexagon for 6 (unscrew the fine filter) So, let's start: Raise the machine and put on reliable stops Remove the plastic protection, it prevents us from unscrewing the front pallet bolts.

We take a bowl or bottle of at least 5 liters, unscrew the bolt by 19 and drain about 5 liters of oil



After that, unscrew the bolts of the pallet, carefully hold it, because there is still about a liter of oil



Here is a pallet with magnets

Then remove the coarse filter. ATTENTION! One bolt is shorter than the others, located in the corner and secures the wire plate



Then a fine filter





There is still a small amount of oil in both filters.Take the coarse filter and sump and go to clean





It is best to clean with a carbcliner, it will clean well under the pressure of the jet. I ran out of it at the very beginning, because everything went to clean the remote control. I had to clean it with gasoline. We remove the magnets and clean them too. It remained unclear to me that there are several pieces of black wires in this block, which are simply dangling in pieces ... for what purpose? maybe who knows?

I still had to long and tediously peel off the old black sealant from the pallet, bolts and variator housing - an indicator that someone had already thrust their unprofessional snout into the variator.
After that we put the magnets in place.
We take a new fine filter and put it in place
We fasten the coarse filter

We check all the bolts very carefully! So that there are no unnecessary parts, dirt, lint, etc.

We put a new gasket on the pallet

We put back the pallet with the gasket, after tightening the drain plug first. We stretch the bolts cross to cross.

After that, we start the engine, bring it to operating temperature, drive the gear selector back and forth, go out and check the fluid level.
We check for a warm, running engine, with the selector in position P!
The oil level should be at the upper shaded border

If there were no more problems, then on this I congratulate. For me, everything did not go so easily, as I already said - someone thrust their stigma into the variator ...
