Automatic transmission in Nissan Cube is a complex hydromechanical unit that requires regular maintenance to maintain smooth shifting and durability. Many owners mistakenly believe that the transmission fluid is filled for its entire service life, but the actual service life without replacement is limited to 60-80 thousand kilometers.
Ignoring maintenance schedules leads to oil oxidation, loss of its lubricating properties and overheating of the clutches. As a result, the car begins to twitch, there are jerks when starting, and in critical cases the transmission can completely fail, requiring expensive repairs or replacement.
Oil change procedure Automatic transmission Nissan Cube is not overly complicated, but requires attention to detail and adherence to temperature conditions. Errors at the stage of draining or adding new fluid can lead to the fact that the oil level is incorrect, which can lead to a drop in pressure and failure of the valve body.
In this article we will look at all aspects of transmission maintenance: from choosing the right one transmission oil to the intricacies of checking the level using a dipstick or drain bolt. We'll also discuss the differences between a partial and a full replacement so you can choose the best method for your vehicle.
Choosing the Right Transmission Fluid for your Cube
The basis for the long life of an automatic transmission is that the oil meets the manufacturer’s technical requirements. For Nissan Cubeequipped with a CVT or a classic automatic (depending on the year of manufacture and market), it is critical to use fluid marked NS-2 or NS-3. The use of non-specialized oils or low-quality analogues will lead to rapid wear of the belt drive (for CVT) or friction discs.
Manufacturer Nissan strictly regulates viscosity and additive package. Liquid Original NS-2 designed for older models and CVTs with lower pressure, while NS-3 has a lower viscosity and is used in new units to reduce friction. Mixing these types of liquids is strictly unacceptable, as this disrupts the chemical balance and properties of the lubricant.
When purchasing oil, pay attention to the packaging and the presence of holograms, since the auto parts market is oversaturated with counterfeit products. A fake may contain abrasive particles that will instantly damage the valve body. The best solution would be to purchase an original canister from a dealer or certified spare parts stores.
If you are not sure what type of fluid is in your car, you need to look at the service book or VIN code. For models from 2008 to 2014 most often used NS-2, however in later versions Nissan Cube updated specifications may have applied. An incorrect choice of oil is the fastest way to kill a transmission.
Preparing tools and work area
Before you begin, you must ensure safe access to the underside of the vehicle. Nissan Cube It has a fairly high ground clearance, but to conveniently drain the oil and dismantle the protection you will still need a lift or pit. If such conditions do not exist, use reliable jacks and stands, and never work under a machine that relies solely on hydraulics.
You will need a set of wrenches, specifically a 14mm socket for the drain plug and a 10mm wrench to remove the guard. Also prepare a waste container with a volume of at least 5 liters and a funnel for pouring new oil. Don't forget to use clean rags and gloves, as the waste liquid has an unpleasant odor and can cause skin irritation.
To accurately check the level, you will need a long hose and possibly a syringe if access to the test hole is difficult. It is important that the engine and transmission are at operating temperature, so plan your trip before starting work.
- 🛠 Socket set and ratchet (sizes 10, 14 mm)
- 🛢 Container for draining used oil (volume from 5 l)
- 🧤 Protective gloves and glasses to protect your eyes from splashes
- 🧼 Clean rags and degreasing agent
Step-by-step instructions for a partial oil change
The process begins with warming up the engine and transmission to operating temperature, approximately 60-80 degrees. This is necessary so that the oil becomes more liquid and comes out of all channels of the valve body. Drive the car onto the lift, set it in a horizontal position and secure it with the parking brake.
Remove the plastic crankcase protection by unscrewing the mounting bolts. Locate the drain hole on the transmission pan. Place the container and carefully unscrew the cap. Be prepared for oil to spray out, so be careful not to spill it on the engine or exhaust system.
After draining completely, drain the oil (about 3-4 liters) and inspect the magnet on the plug. If there are a lot of metal shavings on it, this is a warning sign of internal wear. In this case, it is recommended to wash the pan and replace the automatic transmission filter, which complicates the procedure, but prolongs the life of the unit.
Screw the drain plug into place, first replacing the copper O-ring. Fill the filler hole (usually on the side or top) with fresh oil until it flows back out of the inspection hole. Use Original Nissan NS-2 or recommended equivalent.
☑️ Checklist before starting work
Features of level checking and temperature conditions
A critical step is to check the oil level while the engine is running. On Nissan Cube the level is checked through the control hole located on the pan. The engine should be idling and the gear selector should be moved through all positions (P-R-N-D-L) with a delay of 2-3 seconds each.
The oil temperature should be in the range of 45-55 degrees. If the temperature is higher, allow the engine to cool, as too much oil at high temperatures will cause foaming and loss of pressure. If it’s lower, warm it up again. Accurate adherence to the temperature window of 45-55°C is a prerequisite for correct level diagnosis.
If oil drips from the inspection hole, then the level is normal. If it flows in a stream, the oil has been overfilled. If nothing comes out, you need to top it up. After checking, tighten the control plug, first replacing the O-ring.

Complete oil change using displacement method
A partial replacement allows only 30-40% of the fluid to be renewed, since a significant part of the oil remains in the torque converter and channels. For a complete replacement (100% of the volume), the displacement method is used using special equipment or manually using hoses and a pump. This method is effective, but requires more time and oil (up to 10-12 liters).
With the manual method, the old oil is drained, new oil is poured in, and the engine starts. Then some of the liquid is drained again and new one is added. The process is repeated until the color of the drained liquid becomes identical to the color of the poured liquid. This allows the old fluid to be forced out of the torque converter.
It is important to understand that with high mileage (more than 150,000 km), a complete replacement can be risky. Fresh oil with detergent additives can wash away deposits that clog microcracks or clog the thin channels of the valve body. In such cases, it is better to limit yourself to partial replacement at intervals of 10-15 thousand kilometers.
⚠️ Attention: Never carry out a complete oil change in the automatic transmission on cars with a mileage of over 200,000 km, if the change has not been made before. This can lead to immediate failure of the valve body due to contamination of the channels with wear products.
Why can't you change the oil on old gearboxes?
During long-term use, deposits form in the box, which act as a sealant for worn seals. The new washing fluid washes away these deposits, which leads to a loss of pressure and slipping of the clutches.
Typical errors and symptoms of problems
One of the most common mistakes is ignoring the replacement of the coarse filter. This filter is located inside the pan and becomes clogged with wear products over time. If you change only the oil without changing the filter, the throughput of the system will decrease, which will lead to overheating and lack of pressure.
Another mistake is using the wrong O-ring. The copper washers on the drain and control plugs are disposable. Repeated use causes oil leakage, creating a fire risk if oil gets into the hot exhaust manifold.
Symptoms of improper oil change may not appear immediately. If you notice that the transmission kicks when shifting, jerks when cold, or does not engage reverse gear, immediately check the fluid level and quality. Timely diagnostics can save the box from major repairs.

How many liters of oil are needed for a complete oil change in a Nissan Cube?
For a complete replacement using the displacement method, about 7-8 liters of liquid will be required. For a partial replacement, 3-3.5 liters is sufficient, since a significant portion of the old fluid remains in the torque converter.
Is it possible to mix NS-2 and NS-3 oils?
It is strictly not recommended to mix these types of oils. They have different chemical compositions and viscosities. Mixing can lead to sedimentation and loss of fluid performance properties, which is dangerous for the variator.
How often do you need to change the oil in a Nissan Cube CVT?
Official regulations may not indicate replacement, but experts recommend doing this every 60,000 km during quiet driving. In city conditions and traffic jams, it is better to reduce the interval to 40,000 - 50,000 km.
What to do if the oil leaks after changing?
Most likely, the drain plug was damaged or the copper o-ring was not replaced. Inspect the pan and plug, replace the washer if necessary and tighten the bolt with the recommended torque without overtightening the threads.
