Automatic transmission on Nissan Wingroad is one of the most reliable units, but only subject to timely maintenance. Many owners mistakenly believe that transmission fluid is filled for life, but this misconception can lead to costly repairs.
Regular changing automatic transmission oil allows you to extend the life of the torque converter, solenoids and clutches, while maintaining smooth shifting. Ignoring this process often ends with the box starting to kick, make noise, or completely refuse to shift into higher gears.
Owners Nissan Wingroad It is important to understand the difference between partial and complete replacement, as well as to know the specifics of selecting the original fluid. Incorrectly selected oil or improper draining and filling technology can lead to incorrect operation of the entire transmission system.
Choosing the Right Transmission Fluid
Gearbox on model Nissan Wingroad extremely sensitive to the type of liquid used. Manufacturers recommend using only certified standard oils NS-2 or NS-3, depending on the year of manufacture of the car and the type of transmission installed.
Using non-approved generic fluids or third-party oils may cause the O-rings to swell, causing leaks or loss of system pressure. It is important to check the technical documentation specifically for your body, since in different modifications Wingroad there may be different units.
- ๐ด Original liquid Nissan Matic S โ the optimal choice for most models with a box RE4F04B.
- ๐ต Standard liquid NS-2 - mandatory for CVTs, if we are talking about hybrid versions (although more often it is a purely automatic transmission).
- โช Silicone additives are strictly prohibited, as they destroy rubber products inside the valve body.
Don't try to save money by mixing old and new oil or using cheaper alternatives. In the long term this will result in the need for major renovations. torque converter.
โ ๏ธ Attention: If on your Nissan Wingroad a variator (CVT) is installed, the use of oil for a classic automatic transmission is guaranteed to lead to the destruction of the belt and cones in a few thousand kilometers.
Before purchasing, make sure the canister is marked with the exact standard required for your box. Often sellers may make the mistake of offering NS-3 fluid for a box that requires NS-2, which is unacceptable.

Partial or complete replacement: what to choose?
There are two main methods of servicing the transmission: partial replacement and complete replacement with the device. For Nissan Wingroad With a mileage of more than 100,000 km, experts often recommend starting with a partial replacement, so as not to cause clogging of the channels with wear products.
During a partial replacement, only the volume of oil in the pan is drained, which is about 30-40% of the total amount. This allows you to refresh some of the fluid without the risk of large particles of dirt being washed into the valve body, which could clog the solenoids.
- ๐ ๏ธ Partial replacement is a safe method for used cars, allowing you to update up to 40% of the volume.
- ๐ Complete replacement - effective only on new cars or after preliminary washing of the pan and filter.
- ๐ Dynamic replacement - requires special equipment and can be dangerous for old boxes with worn clutches.
If you decide to do a complete replacement, be sure to replace the filter and wash the pan. Ignoring cleaning the pan will negate the entire effect of changing the oil, as old dirt will mix with fresh fluid.
โ ๏ธ Attention: On cars with high mileage, a complete hardware replacement may cause the box to fail due to the fact that a powerful jet of new oil under pressure will wash away deposits and direct them into the narrow channels of the valve body.
The decision on replacement method must be made individually, based on the current condition of the transmission and its service history. If the machine has been used in difficult conditions, it is better to follow a conservative strategy.
Preparing for the replacement procedure
Before starting work, it is necessary to prepare the vehicle and tools. Nissan Wingroad must be installed on a flat surface, preferably on a lift or inspection hole, since access to the drain plug and pan from below is limited.
You will need a set of keys, a container for draining waste fluid (with a volume of at least 5 liters), a new automatic transmission filter (if provided for by the design) and a pan gasket. Also, do not forget to stock up on rags and gloves, as the oil has an unpleasant odor and is difficult to wash off the skin.
โ๏ธ Preparing for an oil change
The engine must be warmed up to operating temperature so that the oil becomes less viscous and drains more easily. However, you should not carry out the procedure immediately after a long trip; let the box cool to 40-50 degrees to avoid burns from contact with hot parts.
- ๐ก๏ธ Oil temperature - should be in the range of 40-50ยฐC for safe draining.
- ๐ง Tools - 10, 14 and 17 mm wrenches, funnel, syringe for refilling.
- ๐งผ Consumables - a new pan gasket (if metal) or sealant (if rubber).
Check the condition of the drain plug: if it is magnetic, clean it of metal shavings. The presence of large chips may indicate serious problems with the gears or clutches.
Before unscrewing the drain plug, be sure to check the oil level through the dipstick (if there is one) or the inspection hole to make sure there is no overfilling or underfilling before starting work.
Step-by-step replacement instructions
The replacement process begins with unscrewing the drain plug on the pan. Place the prepared container and allow all possible liquid to drain. Typically, 3 to 4 liters leak out, depending on the volume of the box.
Next, you need to remove the pan by unscrewing all the bolts around the perimeter. Be careful as there may be oil left inside. After removing the tray, inspect the magnets on its walls and clean them of metal dust.

Replace the filter if provided by the design. On some modifications Nissan Wingroad the filter is non-replaceable and is located inside the housing, but in most cases it is accessible for replacement when the pan is removed.
Reinstall the pan using a new gasket. Tighten the bolts crosswise with the same force to avoid misalignment and subsequent leakage. Do not use sealant if the standard rubber gasket is installed.
What to do if the gasket breaks?
If the original gasket breaks during dismantling, you can temporarily use a special automatic transmission sealant, but this is not recommended for permanent use. It is better to immediately buy a new spare part, since the sealant can clog the thin channels of the valve body over time.
After installing the pan, you need to fill in new oil through the hole for the dipstick (or through the control hole if there is no dipstick). Use a syringe or funnel with a flexible hose for easy refilling.
Correct installation of the pan and replacement of the filter is 80% of the success of the procedure, since dirt and poor-quality sealing are the main causes of repeated problems with the box.
Checking the oil level
A critical step is to check the oil level correctly. In boxes Nissan the level is checked with the engine running and the transmission warm, when the oil is in the operating temperature range.
To check, switch the selector to all positions, holding each position for a few seconds. This is necessary to fill the valve body and torque converter channels with fluid in order to obtain accurate readings.
The level must be between the marks LOW and HOT on the dipstick. If there is no dipstick, the level is checked through the inspection hole: oil should drip slightly from it when the engine is running.
- ๐ HOT mark - the level is checked at an oil temperature of 50-60ยฐC.
- ๐ Underfilling leads to gear noise and overheating of the box.
- ๐ Overfilling - causes oil foaming and loss of pressure, which can lead to slipping.
If the level is below normal, add oil to the mark. If it is higher, it is necessary to drain the excess through the drain plug. Excessive oil volume in an automatic transmission is just as dangerous as its lack.
| Parameter | Meaning | Note |
|---|---|---|
| Oil volume (partial) | 3.5 - 4.0 liters | Depends on box type |
| Oil volume (full) | 7.5 - 8.5 liters | Including torque converter |
| Check temperature | 50-60ยฐC | Engine operating temperature |
| Liquid type | Nissan Matic S / NS-2 | Strictly according to specification |
| Replacement interval | 60,000 km | Recommended mileage |
After checking the level, close the plug and make sure there are no leaks. Start the engine and let it idle while observing the condition of the connections.
โ ๏ธ Attention: Monitoring the oil level at a temperature of 50-60 degrees Celsius is a prerequisite for the correct operation of the Nissan Wingroad gearbox, otherwise errors in gear shifting are possible.
Common mistakes and tips
Many owners make the mistake of changing the oil only when the transmission starts to have problems. Regular maintenance should be carried out every 60,000 km, even if the car is operated in a gentle manner.
You should not use various additives to โrestoreโ the box. In most cases, they only mask the symptoms, but do not solve mechanical problems, leading to faster wear of parts.
- ๐ซ Additives - can upset the balance of the chemical properties of the oil and cause coagulation.
- ๐ซ Savings - cheap oil quickly loses its properties and does not provide protection.
- ๐ซ Skip replacement - dirt accumulates and clogs the hydraulic unit, which leads to the replacement of the entire unit.
If you notice that the oil is dark and has a burning smell, this is a signal that the box is overheating. In this case, one oil change may not be enough; diagnostics of the condition of the clutches and solenoids will be required.
Compliance with all recommendations and the use of quality materials is the key to long service life of your automatic transmission. Nissan Wingroad.
Frequently Asked Questions
How often do you need to change the oil in a Nissan Wingroad automatic transmission?
The recommended interval is 60,000 km or once every 3-4 years, depending on operating conditions. For aggressive driving or frequent traffic jams, it is better to reduce the interval to 45,000 km.
Is it possible to mix oils from different manufacturers?
It is strictly not recommended to mix oils of different brands and specifications, even if they both meet the NS-2 standard. This can lead to a chemical reaction and loss of fluid properties.
What should I do if the oil turns dark after changing?
If the oil darkens immediately after changing, this may be a sign of active leaching of dirt from the inner walls. If after 1000 km the color does not stabilize, the box may need to be replaced or diagnosed again.
Do I need to change the filter during a partial oil change?
For partial replacement, it is not necessary to change the filter, but it is highly recommended. If the filter is very old, it is better to replace it at the next full change to avoid the risk of clogging.
Is it possible to drive the car immediately after changing the oil?
You can drive, but for the first 100 km it is recommended to avoid sharp accelerations and high speeds in order to allow the new oil to be evenly distributed throughout the entire system and to check for leaks.
