Automatic transmissions on crossovers Nissan Murano are complex engineering units that require impeccable maintenance. The smoothness of gear shifting, acceleration dynamics and the service life of the entire transmission directly depend on the condition of the working fluid. Many owners mistakenly believe that the transmission does not require attention, but this misconception can cost you tens of thousands of rubles in major repairs.
The oil change procedure may look intimidating for a beginner, but if you follow the technology, it can be done in a garage. The key is to understand the difference between a partial and a full upgrade, and know the specifications for your generation Murano. Errors in choosing the type of fluid or flushing temperature can lead to fatal consequences for the valve body and clutches.
Features of transmissions on Nissan Murano
Depending on the year of manufacture and generation of the model, Nissan Murano is equipped with two fundamentally different types of transmissions. The first generations (Z50) and some versions of the second (Z51) use a classic hydromechanical automatic transmission Jatco JF613E (RE6R01A series) with six gears. This is a reliable unit that requires regular oil changes every 60,000 km.
More modern modifications, especially from 2015 onwards, are equipped with a continuously variable transmission CVT (JF016E or RE0F11A series). CVTs are extremely sensitive to fluid quality and operating temperature. They use a special NS-3 fluid, which differs significantly in viscosity and additives from oil for a classic automatic machine. It is strictly forbidden to confuse them.
The classic automatic on early models is more resistant to overheating and allows some deviations in service intervals, while the variator requires strict control. At the first sign of kicking, delays in switching or humming, you must immediately check the level and condition of the fluid. Ignoring the symptoms often leads to wear on the cones and chains in the variator.
- 🔧 Classic automatic Jatco 6L (RE6R01A) - reliable, requires Matic-S or Matic-J oil.
- ⚙️ CVT variator (JF016E) - requires strict adherence to temperature conditions when replacing.
- ⚠️ Mixing types of fluids leads to the destruction of friction linings and the torque converter.
Choosing the Right Transmission Fluid
The key to the longevity of the box is the correct choice of liquid. For a classic slot machine Nissan Murano first and second generation, the manufacturer prescribes the use of original fluid Nissan Matic S or Matic J. Cheap analogues often cannot withstand loads and quickly lose their properties, causing premature wear.
For CVTs, only standard fluid is relevant Nissan CVT Fluid NS-3. Previously, NS-2 was used, but it is not suitable for new models. If you pour NS-2 into a box that requires NS-3, it will change the coefficient of friction and cause the belt to slip. The reverse situation (NS-3 in an old CVT) is also unacceptable.
There are also high-quality non-original substitutes from brands such as Petronas, Motul or Fuchs, having the manufacturer's approval. However, to guarantee the result, it is better to use the original. Saving on fluid may result in the need to replace the entire variator, the cost of which is comparable to the price of a used car.
⚠️ Attention: Never use “All-Friction” universal transmission fluids for Nissan CVTs. They do not provide the necessary coefficient of friction for the operation of the cone pair and can lead to slipping after just a few thousand kilometers.
Instruments and preparation for the procedure
Before starting work, you need to prepare everything you need so as not to be distracted during the process. You will need a set of wrenches, a funnel, a drain hose, and a waste container. It is important to ensure the cleanliness of the work area, since dust entering the transmission is unacceptable.
To accurately diagnose the oil level and temperature, you will need a diagnostic scanner or multimeter with a temperature sensor. In modern cars Nissan Murano There is no classic dipstick for checking the oil level in an automatic transmission, so the procedure is performed using the inspection hole. This makes the process more complex, but makes it more accurate if done correctly.
Be sure to purchase new oil in a volume of at least 6 liters for a partial replacement and up to 10-12 liters for a full circulation. Also, don’t forget about the drain plug O-ring and pan gasket if you plan to remove it to replace the filter.

☑️ Preparing for an oil change
Step-by-step instructions for partial replacement
Partial oil change is the most common maintenance method, allowing you to renew up to 40-50% of the fluid in the system. The process begins with warming up the transmission to an operating temperature of about 50-60 degrees. This is critical because the viscosity of the oil changes with heat.
After warming up, the car is placed on a flat surface. Place a container under the drain plug and unscrew the plug. The oil drains by gravity, taking wear products with it. It is important not to lose any metal shavings, if any, as this is an indicator of the internal condition of the unit.
After draining, the plug is screwed in with a new O-ring. Fresh oil is poured through the filler hole (which is often combined with the control hole). The level is checked with the engine running in neutral gear, when the oil temperature reaches a strictly specified range.
When performing work, it is important to follow the sequence of actions. If you are not confident in your abilities, it is better to entrust the procedure to professionals. An error in determining the level can lead to oil foaming and loss of pressure in the system.
What should you do if the oil is dark and smells burnt?
This is a sign of severe wear on the clutches or overheating. In this case, simply changing the oil will not solve the problem. It is recommended to completely flush the system under pressure and diagnose the valve body. If there are metal shavings, get ready to repair the box.
Complete replacement by displacement method
A complete oil change is carried out using the displacement method through the automatic transmission cooling radiator. This method allows you to renew up to 95% of all fluid, including that in the torque converter. To do this, special equipment or a technique using hoses and a pump is used.
The procedure requires connecting hoses to the radiator pipes. The engine starts and the old fluid is replaced by new fluid. It is important to control the color of the leaking liquid - when it becomes as clear as the poured oil, the process can be considered complete. Usually about 12 liters of new fluid are required.
This method is effective, but has risks. If there is a lot of sludge in the system, the leaching of large particles can clog the thin channels of the valve body. Therefore, a complete replacement is recommended for cars with a mileage of up to 150,000 km, subject to regular maintenance. For heavily worn units, it is better to limit yourself to partial replacement.
| Parameter | Classic automatic (6L) | CVT (CVT) |
|---|---|---|
| Liquid type | Nissan Matic S / Matic J | Nissan CVT Fluid NS-3 |
| Replacement interval (partial) | 60,000 km | 45,000 - 60,000 km |
| Volume for partial replacement | ~5 liters | ~4-5 liters |
| Volume for complete replacement | ~10-11 liters | ~11-12 liters |
| Level check temperature | 50-60°C | 45-55°C |
⚠️ Attention: When completely replacing using the displacement method, be sure to check the condition of the automatic transmission cooling radiator. A clogged radiator can lead to overheating of the new fluid in the first kilometers of driving, especially if the old system had problems with cooling.
Replacing the filter and pan gasket
A partial oil change often does not involve removing the pan, but it is necessary for quality service. The tray contains a magnet that collects metal shavings and a coarse filter. If the filter is clogged, the pressure in the system drops and the transmission begins to operate jerkily.
When removing the pan, be sure to clean it of old sealant and metal dust. Wipe the magnets until they shine. Install a new filter and a new pan o-ring. Using old sealant or misaligning the pan will lead to oil leakage, which is dangerous for the entire transmission.
Some models Nissan Murano The filter is built into the hydraulic unit and is not a replaceable element, but in most cases it is removable. Check the condition of the filter mesh - if it is damaged, replacement is required. A clogged mesh is one of the main reasons for failure of CVTs.
Before installing the pan, apply a thin layer of sealant to the corners and joints, but avoid getting it into the system. Excess sealant can come off and clog the valve body oil passages, leading to costly repairs.
Typical maintenance errors
One of the most common mistakes is ignoring the temperature when checking the level. If the oil level is checked "cold" or at too high a temperature, the reading will be incorrect. This can lead to overfilling or underfilling, which is harmful to the box.
Another mistake is using “universal” additives and cleaners. Manufacturers Nissan It is not recommended to use any chemical additives in transmission fluid. They can upset the additive balance and cause foaming or changes in viscosity.
You should also avoid long drives immediately after an oil change if you used the displacement method. Give the box time to adapt to new conditions. If noise or vibration occurs after replacement, stop immediately and check the level and pressure.
- ❌ Checking the level without taking into account the oil temperature will lead to an error of 10-15%.
- ❌ Mixing fluids of different standards (NS-2 and NS-3) - destruction of friction clutches.
- ❌ Ignoring filter replacement - pressure reduction and overheating.
Regularly changing the oil and filter is cheaper than overhauling a CVT or automatic transmission. Neglecting this rule reduces the transmission life by 2-3 times.
Diagnostics and adaptation after replacement
After changing the oil, especially on a CVT, the gearbox may need to be adapted. In some cases, the computer will remember the wear patterns of the old fluid and shifts may feel rough. A diagnostic scanner is often required to reset adaptations.
The adaptation process includes warming up the box, driving in different modes (acceleration, braking, coasting). This helps the valve body “adapt” to the new physical properties of the fluid. On modern models Nissan Murano adaptation occurs automatically, but sometimes a forced reset is required.
If you have problems with switching after changing the oil, do not panic right away. Let the car drive 200-300 km. Often the box simply “gets used” to the new fluid. If the problem persists, you need to check the system pressure and the condition of the torque converter.
⚠️ Attention: If after changing the oil there are strong vibrations or jerking when moving, this may indicate that the old fluid has already served as a lubricant for worn parts. In this case, a complete replacement could make the situation worse. It is recommended to return to the partial replacement method.
Conclusion and recommendations
Changing the automatic transmission oil Nissan Murano - This is a mandatory procedure that directly affects the service life of the transmission. Maintaining intervals, using the right fluids and doing the job well will ensure smooth operation of the box and no problems in the future.
Don't try to save money on fluid or filters. The cost of quality service is not comparable to the cost of repairing or replacing a transmission. Regularly check the oil level and the condition of its color - this will help you notice problems in time.
Remember that every transmission is different. Consider the characteristics of your vehicle, driving style and operating conditions. When in doubt, always contact specialists who have experience working with boxes Jatco and CVTs Nissan.
Timely oil changes are an investment in the reliability of your car. Neglect of maintenance leads to fatal breakdowns, the repair of which can cost up to 50% of the cost of the car.
How often do you need to change the oil in a Nissan Murano automatic transmission?
The manufacturer recommends changing the oil every 60,000 km for a classic automatic and every 45,000 - 60,000 km for a CVT. Under severe operating conditions (traffic jams, off-road, towing), the interval should be reduced to 30,000 - 40,000 km.
Is it possible to mix oils from different manufacturers?
It is strictly not recommended to mix oils of different manufacturers and standards. Even if they have the same marking (for example, NS-3), their chemical composition may differ, which will lead to transmission problems. Use only original fluid or certified analogues.
How to check the oil level in an automatic transmission without a dipstick?
The level is checked through the control hole with the engine running and the gearbox warm (oil temperature 50-60°C). Liquid should drip from the hole. If there is no oil, you need to add it. If it flows in a stream, the excess must be drained. For accurate measurements, use a multimeter with a temperature sensor.
What to do if jerking occurs after changing the oil?
The box may need adaptation. Drive in different modes to adjust the valve body to the new fluid. If the problem persists, check the oil level and filter condition. There may be contaminants left in the system or a low-quality fluid may have been used.
How much oil is needed for a complete change?
A complete replacement using the displacement method requires 10 to 12 liters of fluid, depending on the type of transmission and year of manufacture of the vehicle. For a partial replacement, 5-6 liters are enough. Always purchase oil with a small supply.
