Automatic transmission in Nissan Note is a complex hydromechanical unit that requires regular maintenance for long service life. Many owners mistakenly believe that the oil filled at the factory is designed to last the entire life of the car, but this is a myth that can lead to expensive repairs.
Timely replacement transmission fluid allows you to maintain smooth shifting, prevent overheating of the valve body and avoid wear of the clutches. This is especially true for cars with a mileage of more than 60 thousand kilometers, where operating conditions often include city traffic jams and aggressive driving styles.
In this article we will analyze all the nuances of the procedure: from choosing the right liquid to a step-by-step algorithm of actions. You will learn how to distinguish a partial replacement from a complete one, why it is critical to observe the temperature regime, and what mistakes even experienced craftsmen make.
Replacement intervals and signs of fluid wear
Manufacturer Nissan Technical documentation often indicates that the automatic transmission oil does not require replacement, but actual operating conditions dictate their own rules. For Nissan Note with CVT or classic automatic Jatco the optimal interval is 60,000 kilometers or 4 years of operation, whichever comes first.
If the car is used in taxi mode, often tows a trailer, or mainly drives around the city in traffic jams, the interval should be reduced to 40,000 kilometers. Ignoring this rule leads to oxidation of the liquid, loss of its lubricating properties and accumulation of metal shavings.
You can determine that the oil has become unusable by a number of external signs. Pay attention to the color and smell of the fluid when checking the level. If the oil has darkened, acquired a cloudy hue, or has a burning smell - replacement needed immediately.
- 🔴 The liquid has turned dark brown or black, indicating oxidation and overheating.
- 🔴 There is metal suspension or shavings on the probe (if it is provided for by the design).
- 🔴 Gears are switched on with jerks, kicks, or extraneous noise is heard when moving.
- 🔴 Vibration appeared when switching modes

Choosing the Right Transmission Fluid
To the choice of oil for Nissan Note it must be approached with maximum responsibility, since modern automatic transmissions are sensitive to viscosity and chemical composition. For Jatco gearboxes installed on these cars, the manufacturer requires the use of original fluid NS-2 or NS-3 depending on the generation of the unit.
The use of analogues is possible, but only with appropriate certification and approval from the box manufacturer. Incorrect selection of fluid can lead to a change in the coefficient of friction of the clutches, which will cause slipping and failure of the torque converter.
It is important to distinguish between fluids for CVTs and classic automatic transmissions, as they have different viscosities. For Nissan Note most often used with a variator NS-2 (for older models) or NS-3 (for new ones), whereas for a classic 4-speed automatic transmission, type fluid is suitable ATF Matic D.
| Gearbox type | Recommended Liquid | Liquid color | Volume with full replacement (l) |
|---|---|---|---|
| CVT Jatco (old) | Nissan CVT Fluid NS-2 | Green | 7.5 - 8.0 |
| CVT Jatco (new) | Nissan CVT Fluid NS-3 | Red | 7.0 - 7.5 |
| Classic automatic (4 speed) | Nissan Matic D | Red | 6.5 - 7.0 |
| Classic automatic (6 speed) | Nissan Matic J | Red | 7.0 - 7.5 |
Tools and preparation for work
Before starting work, it is necessary to prepare all the necessary equipment and ensure the safety of the process. You will need a reliable lift or inspection hole, as access to the transmission pan and drain hole must be unobstructed. You will also need a set of keys, a funnel and a container for draining the waste liquid.
Pay special attention to cleaning the area around the drain and fill plugs. Dirt trapped inside the transmission can block the solenoids and damage the valve body. Use carburetor cleaner and a rag to thoroughly wipe down the pan before removing the plugs.
Don't forget about a new pan gasket if you plan to remove it, and a new coarse filter if it is included in the design of your model. Saving on these consumables often leads to leaks and dirt getting into the system.
- 🛠️ A set of socket and open-end wrenches (including a 14, 17 and 19 mm wrench).
- 🛠️ A container for draining waste with a volume of at least 8 liters.
- 🛠️ Funnel with a flexible hose for convenient oil filling.
- 🛠️ Torque wrench for precise tightening of pallet bolts.
- Less than 50,000 km
- 50,000 - 100,000 km
- 100,000 - 150,000 km
- More than 150,000 km
Step-by-step instructions for a partial oil change
Partial replacement is the most common maintenance method, in which only the oil that is in the sump is drained without removing the torque converter. This method allows you to renew about 30-40% of the fluid volume and remove the bulk of wear products.
The process begins by warming up the gearbox to operating temperature (about 50-60°C) so that the oil becomes less viscous and flows better. Then the car is placed on a flat surface, and a container is placed under the drain hole. Unscrew the drain plug and allow the liquid to drain completely.
After draining the waste, it is necessary to remove the pan to clean the magnets and replace the filter. Carefully remove metal shavings from the magnets and wash the tray itself with solvent. Install a new filter and gasket, tighten the pan bolts to the recommended torque to avoid distortion.
Next, fill in fresh oil through the filler hole to the level corresponding to the marks on the dipstick or inspection hole. It is important to observe the temperature conditions when checking the level: the engine must be idling, and the gear selector must go through all modes and stop in position P.
☑️ Preparation and draining
What to do if there is no dipstick?
Modern Nissan Notes often lack a dipstick to check the oil level. In this case, the check is carried out through the inspection hole on the pallet. Oil should start dripping from this hole when the engine is running and the temperature is 35-45°C. If there is no oil, you need to add it; if it flows in a stream, drain off the excess.
Features of complete replacement using the displacement method
A complete oil change requires the use of special equipment to displace the old fluid with new fluid under pressure. This method allows you to renew up to 95% of the volume, including the fluid in the torque converter and cooling radiator. This is the most effective way to restore automatic transmission performance.
The procedure is performed on a stand where the hoses of the device are connected to the radiator tubes for cooling the box. The old fluid is replaced by a new one until the output appears clean oil of the same color as the poured one. This takes longer and requires a larger volume of new fluid.
It is worth noting that a complete replacement is not recommended for cars with very high mileage and the oil has never been changed. In such cases, the old fluid already acts as a sealant for worn clutches, and its sudden replacement can lead to slippage and failure of the box.
⚠️ Attention: Complete replacement using the displacement method is strictly prohibited if the system shows signs of serious mechanical damage or if the oil has not been changed for a long time and has a burning smell.
Before the complete replacement procedure, be sure to carry out diagnostics with a scanner for errors in temperature and pressure in the system. If there are errors, fix them first and then change the oil.
Temperature control and level check
A critical step is to check the oil level correctly, which is dependent on its temperature. For most automatic transmissions Nissan There are two testing ranges: cold (20-30°C) and hot (45-55°C). An error in determining the temperature will lead to an incorrect level, which can lead to foaming of the liquid or lack of liquid.
When checking on a warm engine, the gear selector must go through all positions from P up to D and back, pausing for each 2-3 seconds. This is necessary to fill all channels of the valve body and torque converter with liquid. Only after this is the selector set to position P or N for final check.
If the level is below normal, add fluid until drops appear from the control hole. If the level is higher, it is necessary to drain the excess, since excess pressure can squeeze out the seals and cause leaks. Do not neglect this step, even if it seems that there is enough oil.
- 🌡️ Use a diagnostic scanner to accurately read the oil temperature from the automatic transmission control unit.
- 🌡️ Do not check the level on a cold engine unless you use the “cold level” method with the appropriate marks.
- 🌡️ Make sure the car is on a completely flat surface for correct readings.
Correctly checking the oil level at an operating temperature of 45-55°C is a guarantee of no jerking or slipping in the future.
Common mistakes and their consequences
Often, owners and even unskilled technicians make fatal mistakes when changing the oil. The most common problem is the use of low-quality or incompatible fluid. Mixing different types of oils, e.g. NS-2 and NS-3, leads to a change in the chemical composition and destruction of seals.
Another mistake is ignoring the filter state. If the coarse filter is not replaced, it continues to let dirt into the valve body, negating the effect of changing the oil. They also often forget to change the aluminum gasket of the drain plug, which leads to leakage.
Incorrect tightening of the pallet bolts may cause the pallet to become deformed or come loose due to vibration. Use a torque wrench and tighten the bolts crosswise in several passes to the torque specified in the service book, usually around 4-5 Nm.
⚠️ Attention: Changing the oil in an automatic transmission with a mileage of more than 200,000 km without preliminary diagnostics can lead to a complete stop of the gearbox due to loss of tightness of worn seals.

At the end of the article, we have collected answers to the most popular questions that owners have. Nissan Note when servicing the transmission. This information will help you avoid unnecessary expenses and mistakes.
How often do you need to change the oil in a Nissan Note CVT?
The recommended interval is 60,000 km or every 4 years. When operating in difficult conditions, the interval is reduced to 40,000 km.
Is it possible to mix NS-2 and NS-3 oil?
Absolutely not. These liquids have different viscosities and chemical compositions. Mixing will lead to failure of the variator.
Do I need to warm up the box before replacing it?
Yes, heating to 50-60°C is necessary so that the oil becomes less viscous and completely drains from the pan.
What to do if jerking appears after replacement?
The oil level may be incorrect or the wrong fluid has been used. This may also be a sign of wear on the clutches, which is hidden by old thick fluid. Diagnostics required.
Is it possible to do a complete replacement on an old car?
If the oil has never been changed and the mileage is high, a complete replacement is dangerous. It is better to make a partial replacement and repeat it after 1000 km in order to smoothly update the composition.
