A complete guide to the original Nissan CVT Fluid NS-3 oil: part numbers, selection and replacement

Car owners faced with the need to service a transmission often wonder about the exact identification of consumables. If your Nissan equipped with a Jatco CVT manufactured after 2012, the correct choice of lubricant becomes critical to the longevity of the transmission. Many people mistakenly believe that it is enough to buy any oil for CVTs, but modern requirements for viscosity and additive package dictate strict standardization.

The focus is on the specification Nissan CVT Fluid NS-3, which replaced the outdated version NS-2. The difference between these liquids is colossal, and mixing them is unacceptable. In this article, we will analyze in detail the original 1-liter packaging items, learn how to distinguish a fake and find out which models require this particular liquid.

Current articles and packaging of the original liquid

When searching for consumables in spare parts catalogs, it is important to focus on the exact manufacturer number. For a 1 liter canister, the main original article number is KE901-90E34. It is under this number that the liquid is supplied to official dealerships and large auto parts stores. However, it is worth considering that logistics codes may vary slightly depending on the region of delivery and the year of production of the batch.

There is also an option with the article KE901-90E35, which is most often found in configurations for large markets or specific supply chains. Visually, the canister has a characteristic yellow-orange color with clear markings Nissan Genuine Parts. Pay attention to the security hologram on the lid - the absence of this element often indicates counterfeit.

In addition to single canisters, manufacturers offer smaller volume canisters for partial replacement or refilling, as well as barrels for large services. But for the average car owner who does the maintenance himself, the 1 liter format is the most convenient and economical.

When ordering through online stores, always check the code on the package with the code in the order. Errors in figures may result in the supply of incompatible fluid, which will be fatal to CVT. If you see a price that is suspiciously low, this is a reason to be wary: the original liquid cannot be cheap due to the complex formulation of additives.

Differences between NS-3 and NS-2 and the ban on mixing

Many owners Nissan Qashqai or Teana previous generations were accustomed to oil NS-2. However, with the advent of new models such as X-Trail (T33) or updated versions Patrol, требования изменились. NS-3 fluid is designed taking into account higher loads and other temperature conditions of the variator operation. Its viscosity is different, which provides better protection for clutches under extreme loads.

The main rule that must be remembered once and for all: mixing NS-2 and NS-3 is strictly prohibited. Even a small amount of incompatible fluid can upset the additive balance, leading to a change in the coefficient of friction and, as a result, slipping of the belt or chain. As a result, you will receive an expensive repair of the valve body or replacement of the entire variator.

If your box was previously filled with NS-2, then switching to NS-3 is only possible if the system is completely flushed. This is a complex procedure that requires special equipment to dislodge the old fluid. Simply replacing part of the volume will not solve the incompatibility problem. For modern models, NS-3 is immediately filled from the factory, and it must be changed strictly to a similar specification.

Manufacturer Jatco, which is a transmission supplier to Nissan, clearly differentiates these products. The technical documentation states that using NS-2 in boxes designed for NS-3 will lead to reduced efficiency and overheating. Conversely, pouring NS-3 into older boxes that require NS-2 may cause torque converter problems due to the difference in density.

⚠️ Attention: Using NS-2 fluid in CVTs requiring NS-3 will lead to rapid wear of the friction linings and loss of pressure in the control system. This is not just a recommendation, but a guarantee of unit failure.

Compatible with Nissan and Jatco models

Determine the need for use NS-3 possible by car model and year of manufacture. This liquid is required for Nissan Qashqai (J11, J10 рестайлинг), X-Trail (T32, T33), Terrano and Kicks. Также она используется в Nissan Teana latest generations and some versions Pathfinder. Если вы владелец Murano or Patrol with a CVT, check the specifications in the service book, as there may be nuances there.

It is important to note that compatibility depends not only on the car brand, but also on the CVT code. Jatco JF015E, JF016E, JF017E variators and their modifications have different viscosity requirements. For example, for Nissan Almera (G15) and Sentra NS-3 is often used. A mistake in choice can be made if you focus only on the visual similarity of the canisters.

There is also a category of cars where backward compatibility or migration is acceptable, but this is rare. Most modern CVTs operate within a narrow range of temperatures and pressures, where the exact viscosity of the oil plays a critical role. You should not rely on the advice of “knowledgeable” people who suggest adding universal liquid - the risk is too great.

When selecting oil, always check your vehicle's VIN. In dealer catalogs, you can find out exactly what fluid was filled in from the factory by VIN. This eliminates errors associated with parallel imports or changes in specifications during the production of the same model.

Instructions for checking the oil level and condition

Checking the oil level in the variator is a procedure that requires strict adherence to temperature conditions. Errors here can lead to incorrect conclusions: overfilling or underfilling is dangerous for the box. You need to warm up the engine and CVT to operating temperature, usually in the range of 50 to 60 degrees Celsius. The exact values ​​are indicated in the service documentation for the specific model.

The test process includes the following steps: start the engine, move the selector to all positions, holding each position for a few seconds, then return it to P or N. Unscrew the control plug and look at the oil stream. If it is thin and dripping, the level is low. If it flows in an even stream, the level is normal.

It is important to evaluate not only the quantity, but also the color of the liquid. Fresh NS-3 has a bright red or pinkish tint. If the oil has darkened, acquired a brown color or a burning smell, this is a signal that the variator is overheating and requires urgent replacement. The presence of metal suspension or shavings on the plug magnet is also an alarming symptom.

For ease of control, you can use the following checklist so as not to miss important diagnostic stages.

☑️ Checklist for checking the oil level

If the level is below normal, you need to add oil through a special hole. Use a funnel with a long hose to deliver the liquid to the pan. Do not overfill the oil, as excessive pressure may push out the seals or cause foam in the torque converter. Foam reduces the effectiveness of lubrication and causes overheating.

⚠️ Attention: Checking the oil level should only be done with the engine running. Stopping the engine will lead to oil draining into the sump and false level readings, which can lead to overflow when topping up.

How to distinguish an original from a fake by article number

The auto parts market is oversaturated with counterfeit goods, especially in the segment of oils and liquids. Fake NS-3 may look like the original, but have a completely different composition. Manufacturers of counterfeits often copy the design of the canister, but make mistakes in fonts, text placement or quality of plastic. Examine the label for typos and blurry images.

Pay special attention to the barcode and article number. On the original canister with the article number KE901-90E34 The numbers must be clear and not erased. Often counterfeiters change the last number or letter so that the code is not checked in official databases. Compare the code on the canister with the code on the manufacturer's website or in the dealer catalog.

The quality of the packaging is also an indicator. The lid must fit tightly and have a protective ring that breaks when first opened. There should be foil or a protective membrane inside the lid. If the canister smells like cheap plastic or oil immediately after opening, this is a clear sign of counterfeit.

Buy consumables only from trusted suppliers. Official dealers and large chain stores guarantee the authenticity of the product. Saving on oil can cost you hundreds of thousands of rubles in CVT repairs. Remember that the variator is a high-precision mechanism that is sensitive to the quality of the lubricant.

What to do if you have already uploaded a fake?

If you suspect that counterfeit fluid has been poured into the variator, you must immediately stop using the vehicle. Completely flush the system and replace the oil with the original one. Do not delay this, as aggressive additives in a fake can begin to corrode seals and clutches after just a few hundred kilometers.

Cost and where to buy the original

Price for original oil Nissan CVT Fluid NS-3 varies depending on region and exchange rate. On average, the cost of a 1-liter canister ranges from 800 to 1500 rubles. Cheaper means the risk of buying a fake, more expensive means perhaps a dealer markup or logistics costs. Keep an eye out for promotions at major stores where you can buy a set of 4 or 5 canisters at a discount.

You should not chase the lowest prices on sites of dubious origin. They often sell “gray” goods that may have been stored in inappropriate conditions. High temperatures in the warehouse can spoil the additives even before the canister reaches your hands. Original oil requires strict storage conditions.

💡

Buy oil in large quantities (for example, 4 cans of 1 liter each) during scheduled maintenance. This is often more profitable than buying one canister at a time, and allows you to have a reserve in case of refilling.

The procedure for changing the oil in the variator

Changing the oil in the variator can be partial or complete. A partial replacement involves draining the old oil from the pan and filling in new oil. This method allows you to renew about 40-50% of the liquid volume. To do this, you need to unscrew the drain plug, drain the oil, remove the pan, replace the filter and gasket, then pour new oil through the hole in the dipstick or filler neck.

A complete replacement requires the use of special flushing equipment. The device is connected to the variator cooling lines and replaces the old oil with new oil under pressure. This allows you to update up to 95-100% of the fluid volume, including the torque converter. This method is more effective, but more expensive and requires the qualifications of a specialist.

When replacing, be sure to replace the filter and pan gasket. The filter traps wear products, and if it is not changed, it will quickly become clogged, which will lead to a drop in pressure and overheating. The pan gasket provides a tight seal, and reusing the old one often results in leaks.

After replacement, it is necessary to perform the adaptation training procedure. The variator must “get used” to the new oil viscosity. This is usually done by warming up and shifting gears in different modes. In some cases, computer diagnostics are required to reset adaptations.

💡

A complete hardware oil change is more effective for extending the life of the variator, but requires professional equipment and skills. Partial replacement is suitable for regular maintenance with a mileage of up to 40-50 thousand km.

Don't forget that the correct replacement procedure includes checking the oil level at a certain temperature. If you do this incorrectly, the level will be incorrect, causing problems. Always follow the manufacturer's instructions for your specific model.
