Owners Nissan Almera Classic Often faced with a dilemma when it comes to transmission maintenance. This is a popular car in Russia, which combines the reliability of Japanese engineering and the availability of spare parts, however, the specifics of its units require a careful approach to the selection of lubricants. Errors in fluid selection can lead to premature gear wear, torque converter overheating, or clutch failure.
Many drivers believe that it is enough to fill in the “first available” oil that matches the coarse viscosity, but this misconception can be expensive. Car manufacturers include strict tolerances in their design decisions, which, if ignored, upset the balance of friction and lubrication within the mechanism. In this article we will analyze in detail which fluids are recommended for different types of gearboxes on this model, what analogues exist and how to correctly carry out the replacement procedure.
Types of transmissions for Nissan Almera Classic and their features
Before you go to the store for a can of oil, you need to clearly determine which unit is installed on your car. Nissan Almera Classic (also known as B10) was offered in two main types of transmissions, each with unique lubrication requirements. Incorrect identification of the box type is the first and most common step towards failure.
Most cars of this model are equipped with a manual transmission series FS5R30A. This unit is characterized by its simplicity of design and reliability, but it is sensitive to the quality of lubrication in winter. The second common version is the classic automatic torque converter unit 4-AT (RE4F03A), which is often found in trim levels with a 1.6-liter engine. It is important to understand that the fluids for these two mechanisms are absolutely incompatible with each other.
Manual transmissions require oils with certain extreme pressure additives that can protect the synchronizers under high loads. At the same time, an automatic transmission needs a specialized fluid (ATF), which performs several functions at once: lubrication, cooling and transmission of hydraulic pressure. Using the wrong type of oil in an automatic transmission can cause the clutches to slip and gear shifting to become jerky and harsh.
- 🔧 Manual transmission FS5R30A requires mineral or semi-synthetic oils with a viscosity of 75W-90 or 80W-90.
- ⚙️ Automatic transmission RE4F03A works exclusively on standard fluid ATF Dexron III or Nissan Matic D specifications.
- ⚠️ It is strictly forbidden to mix manual transmission oil with automatic transmission fluid.
Manufacturer's recommendations for manual transmission
If your car is equipped with a manual transmission, the manufacturer indicates in the service book the need to use oils with a viscosity grade SAE 75W-90 or 80W-90. These parameters mean that the oil must remain fluid at low temperatures, ensuring easy starting and gear shifting, and also create a durable film at high operating temperatures of the engine and gearbox.
Particular attention should be paid to the quality class. For mechanics on Nissan Almera Classic suitable level product API GL-4 or GL-5. Although GL-5 is considered more versatile, in some cases GL-4 is better suited for synchronizers, since it contains less aggressive sulfur additives. However, most modern GL-5 oils are safe for synchronizers provided that high-quality formulations are used.
There are many brands that produce suitable oils, but it is important to choose original products or proven analogues. The original fluid from Nissan has the article number KE909-99931 (75W-90) or KE909-99932 (80W-90). The use of original oil guarantees compliance with all technological standards laid down by engineers when developing the box.
⚠️ Attention: Using oils with a viscosity of 85W-140 or 90W-140 can lead to difficulty shifting gears in the cold season and increased fuel consumption due to the thick consistency.
- ❄️ Winter period: give preference to oil 75W-90 for better pumpability.
- ☀️ Summer period: it is permissible to use a thicker 80W-90 in hot climates.
- 🛢️ Original code:
KE909-99931is the preferred choice for warranty.
Selecting fluid for automatic transmission (automatic transmission)
Automatic transmission on Nissan Almera Classic is a hydromechanical unit that is extremely demanding on the characteristics of the working environment. The manufacturer insists on using standard fluid Nissan Matic D (also known as J3). This is a specific formula developed specifically for Nissan transmissions, which ensures proper friction of the friction discs and smooth shifting.
There are often recommendations on the market to use universal fluids like ATF Dexron III or Dexron VI. Indeed, many services upload Dexron III as an analogue, and it works, but this is a compromise. Matic D fluid has more precise friction properties, which extends the life of the valve body and solenoids. If you plan to use the car for a long time, it is better to find the original fluid.
It is important to note that the machine is Almera Classic does not have a filter in the pan in the classical sense (or it is very simple), so oil purity is critically important. Wear debris entering the hydraulic system can block narrow passages. That is why regular fluid replacement (every 60,000 km) is a mandatory procedure and not an optional one.
- ✅ Optimal choice: original liquid Nissan Matic D (article
KE908-99931). - 🔄 Acceptable analogue: ATF Dexron III (but not mixed with other types).
- ❌ Prohibited: use of Matic J, Matic S or CVT Fluid.
- Mechanics (manual transmission)
- Automatic (automatic transmission)

Comparative table of oils and their characteristics
For clarity, we have compiled a table that will help you quickly navigate the variety of offers on the market. Here are the main parameters that you should pay attention to when purchasing. Please note that the volume of refueling for manual and automatic differs significantly, which also needs to be taken into account when planning expenses.
| Gearbox type | Viscosity (SAE) | Quality class (API/Spec) | Filling volume (l) | Original article |
|---|---|---|---|---|
| Mechanics (manual transmission) | 75W-90 | API GL-4 / GL-5 | 2.6 | KE909-99931 |
| Mechanics (manual transmission) | 80W-90 | API GL-4 / GL-5 | 2.6 | KE909-99932 |
| Automatic (automatic transmission) | ATF (fluid) | Nissan Matic D | 7.5 (full) | KE908-99931 |
| Automatic (automatic transmission) | ATF (fluid) | Dexron III | 7.5 (full) | Various brands |
When choosing an analogue, always check the specifications on the canister with the requirements of your car. If the oil manufacturer indicates compatibility with Nissan Matic D, this means that the composition has passed the necessary tests. You should not save on transmission fluids, since the cost of repairing a gearbox is several times higher than the price of high-quality lubricant.
What is the difference between Matic D and Matic J?
Matic D fluid is intended for classic torque converter automatic transmissions (as on Almera Classic), while Matic J is used in modern Nissan variator transmissions (CVT). Mixing these fluids is unacceptable and can destroy the variator.
Transmission fluid replacement procedure
The process of changing gearbox oil Nissan Almera Classic does not require sophisticated equipment, but requires careful preparation. You will need an inspection hole or lift, a set of keys, a funnel and a container to drain the used oil. It is important to carry out the procedure on a warm car, since warm liquid flows out faster and takes with it more contaminants.
For a manual transmission, you need to unscrew the drain plug located at the bottom of the crankcase. After the waste is completely drained, the plug is cleared of metal shavings (if there is a magnet) and screwed back in. Next, new oil is poured through the filler hole located on the side until it begins to flow out of the same hole. This is the full level.
In the case of an automatic transmission, the procedure is more complicated. It is necessary to remove the pan or unscrew the drain plug (if it is provided for in the design), drain the old fluid, replace the filter (if it is removable) and the pan gasket. Then fresh fluid is poured through the dipstick (if there is one) or the filler hole. The level is checked with the engine warm, with the engine running and gear shifting in all positions.
☑️ Preparation for changing the oil in the gearbox
⚠️ Attention: When working with an automatic transmission, do not confuse the drain plug with the plug located on the valve body or elsewhere. Unscrewing the wrong plug can result in loss of pressure and serious damage.
After replacement, be sure to check for leaks under the car after a few days of use. Even a small leak can reduce the fluid level to a critical level, leading to overheating and transmission failure. Regular visual inspection is the key to long service life of the unit.
Before purchasing oil, be sure to check the vehicle's VIN code, as minor changes in the design of the transmission may have been applied in different years of production.
Common mistakes when servicing transmissions
Many owners Nissan Almera Classic make the same mistakes, which in the future result in expensive repairs. One of the main problems is ignoring replacement intervals. The service book may say “maintenance as needed,” but for Russian operating conditions this means every 40-60 thousand kilometers. Old oil loses its properties, additives precipitate, and lubricity decreases.
Another common mistake is mixing different types of oils. Even if you add oil of the same brand but of a different viscosity or standard, it can cause a chemical reaction that results in the formation of a gel or sediment. This is especially dangerous for automatic transmissions, where the frictional properties of the fluid play a decisive role.
It is also worth mentioning the problem with using “universal” oils for all components. Some experts recommend pouring the same oil into the engine, gearbox and gearbox to simplify logistics. This is a categorically incorrect approach, since the requirements for detergency, extreme pressure and viscosity properties in each unit are fundamentally different.
- 🚫 Do not mix oils from different manufacturers unless absolutely necessary.
- 🚫 Do not use CVT oils in classic automatic transmissions.
- 🚫 Do not neglect replacing gaskets when removing the pallet.

Frequently asked questions (FAQ)
Is it possible to mix Dexron III and Nissan Matic D oils in an automatic transmission?
Although some mechanics allow this practice in emergencies, it is not recommended to do it regularly. Fluids have different chemical compositions, and mixing them can reduce the efficiency of the clutches. It is better to completely replace the oil with the original Matic D.
What volume of oil is needed for a complete change in the automatic transmission on a Nissan Almera Classic?
A complete replacement with flushing or hardware replacement may require about 10-12 liters of fluid, since some of the oil remains in the torque converter and radiator. For a regular partial replacement, 4-5 liters are enough, but this will not update the entire volume.
Is it necessary to change the oil in a manual transmission if the car is rarely driven?
Yes, manual transmission oil oxidizes over time and loses its properties, even if the mileage is short. It is recommended to replace it at least once every 3-4 years or every 60,000 km, whichever comes first.
What happens if you fill in oil with a viscosity of 80W-140 instead of 75W-90?
In winter, such oil will be too thick, which will lead to difficulties with gear shifting and increased wear of synchronizers during cold starts. In summer this is acceptable, but it is better to follow the manufacturer's recommendations.
How to check the oil level in an automatic transmission without a dipstick?
On Nissan Almera Classic The level is often checked through the inspection hole on the box. The car must be on a level surface, the engine is warm and running at idle speed. If oil drips from the hole, the level is normal.
