Gearbox Nissan Almera Classic (also known as Nissan B10 or Samsung SM3 in some markets) is a node that often remains without due attention until it begins to “signal” about problems. Meanwhile, correct choice and timely replacement of gearbox oil can extend the life of the transmission by 100+ thousand kilometers, even if the manufacturer claims that the oil is “for life”. In this article we will look at which oil is suitable for manual and automatic transmissions. Almera Classic, how to replace it correctly, and what to pay attention to so as not to damage the transmission.

Many owners Almera Classic (2006–2012) are faced with a dilemma: should they trust the factory recommendations or rely on the experience of service technicians? The point is that the manual for a manual transmission (RS5F32A) often indicates oil API GL-4 75W-85, but in practice many service stations pour GL-4/5 75W-90 for better protection of synchronizers under high loads. Let's figure out where the truth is and where the myths are.

Types of gearboxes in Nissan Almera Classic and their features

On Almera Classic Two types of gearboxes were installed:

  • 🔧 Mechanical 5-speed (RS5F32A) - the most common, reliable, but sensitive to the quality of the oil. Synchronizers wear out faster if the wrong viscosity is used.
  • 🔄 Automatic 4-speed (RE4F03B) - less common, requires specialized fluid ATF Matic-S or Matic-J.

Important: automatic transmission in Almera Classic - This is a classic torque converter “automatic”, not a CVT. Many people confuse it with CVT, which was installed on newer models Almera (For example, G15). For RE4F03B critical to use only original ATF or certified analogues - for example, Idemitsu ATF Type-J or Ravenol ATF J1.

Mechanical box RS5F32A more “loyal” to oils, but there are nuances here:

  • 🔹 GL-4 - standard for most “mechanics” Nissan, but viscosity 75W-85 may be insufficient for regions with frosts below −25°C.
  • 🔹 GL-5 — not recommended for synchronized gearboxes, as it has an aggressive effect on copper parts. However, some oils (eg. Motul Gear 300 75W-90) have permission GL-4/5 and suitable for Almera Classic.

Original oils and their analogues: what to fill?

The manufacturer recommends for Almera Classic the following oils:

Gearbox type Original oil Article Analogues (tested)
Mechanical (RS5F32A) Nissan MT-XZ 75W-85 KE908-99932 Motul Gear 300 75W-90, Liqui Moly Hochleistungs-Getriebeoil 75W-90, Castrol Syntrans Transaxle 75W-90
Automatic (RE4F03B) Nissan Matic-S KE908-99931 Idemitsu ATF Type-J, Ravenol ATF J1, Aisin ATF AFW+

Among analogues for a manual transmission, it stands apart Motul Gear 300 - it is often recommended by craftsmen due to its high thermal stability and wear protection. However, there is a nuance: this oil is thicker than the original one 75W-85, so in severe frosts there may be problems with shifting gears before the box warms up.

For automatic transmission RE4F03B critical to use only specialized ATF. For example, Toyota Type T-IV or Dexron III don't fit - they will lead to slipping of the clutches and premature wear of the valve body. If original Matic-S out of stock, better take it Idemitsu Type-J - This oil is fully compatible according to specifications.

⚠️ Attention: In automatic transmission Almera Classic You cannot fill in universal “dextrons” or oils for variators. This will lead to failure of the solenoids and torque converter.

Oil volume and replacement frequency

Transmission oil volume Nissan Almera Classic depends on the type of box:

  • 🔧 Mechanical (RS5F32A): 2.8–3.0 liters (with complete replacement with flushing).
  • 🔄 Automatic (RE4F03B): 7.0–7.5 liters (partial replacement - 3.5–4.0 l).

The manufacturer claims that the oil in the manual transmission does not require replacement (so-called “lifetime oil”). However, in practice:

  • 🔹 During intensive driving (city, traffic jams), the oil loses its properties already 60–80 thousand km.
  • 🔹 In quiet mode (highway) - to 100–120 thousand km.
  • 🔹 If the gearbox shifts “tightly” or there is a crunching sound, the oil needs to be changed immediately.

For automatic transmission RE4F03B recommended replacement interval - every 60 thousand km (or once every 4 years). At the same time complete replacement (with removing the pan and replacing the filter) is preferable to partial, since up to 30% of the old oil remains in the valve body and radiator.

Drain the old oil (warm the box to 50–60°C)

Wash the pan (for automatic transmission)

Replace the filter (for automatic transmission)

Pour new oil through the filler neck

Check the level using the dipstick (for automatic transmission) or the control hole (for manual transmission) -->

Step-by-step instructions for changing the oil

For manual transmission (RS5F32A):

  1. Warm up the box (drive 10–15 km).
  2. Raise the car on a lift or pit.
  3. Unscrew drain plug (key 24) and drain the oil into a container.
  4. Screw the plug with a new gasket (part no. 11026-01M02).
  5. Fill in new oil through filler hole (near the left wheel drive) until it begins to leak.
  6. Screw in the filler plug.

For automatic transmission (RE4F03B):

  1. Warm up the box to operating temperature (60–70°C).
  2. Remove the crankcase protection and transmission pan (14 bolts).
  3. Drain oil, replace automatic transmission filter (article 31726-31X01).
  4. Install new pan seal (article 31397-31X00).
  5. Fill oil through dipstick (about 4 liters), then check the level with the gearbox warm.
⚠️ Attention: In automatic transmission Almera Classic oil level is checked with the engine running at an oil temperature of 60–70°C. Overfilling or underfilling by 200-300 ml can lead to foaming or oil starvation.
💡

If, after changing the oil in a manual transmission, gear shifts are difficult, let the oil spread throughout the gearbox and drive 50–100 km. If the problem persists, the oil may be too thick (for example, 80W-90 instead of 75W-85).

Typical mistakes when changing oil

Even experienced car owners make mistakes that can reduce the service life of the gearbox. Here are the most common:

  • 🚫 Using the wrong grade of oil - for example, GL-5 instead of GL-4 for manual transmission. This leads to corrosion of the synchronizers.
  • 🚫 Incomplete automatic transmission oil change — if you do not flush the valve body and radiator, the old oil will mix with the new oil and reduce its properties.
  • 🚫 Overfilling or underfilling - in a manual transmission, excess oil leads to foaming, in an automatic transmission - to increased pressure and leaks.
  • 🚫 Ignoring automatic transmission filter replacement — the old filter becomes clogged with wear products and does not allow oil to pass into the valve body.

Another common mistake is oil change without flushing. Metal shavings and deposits accumulate in a manual transmission over time. If you simply drain the old oil, about 200-300 ml of dirty liquid will remain in the box. Solution:

  • 🔧 Use flushing oil (For example, Liqui Moly Getriebe-Reiniger).
  • 🔧 Rinse the box new oil: fill, drive 500 km, drain and fill completely.
What happens if you don't change the gearbox oil?

In a manual transmission: accelerated wear of synchronizers (crunching when shifting), bearings (hum), difficulty shifting gears when cold.

In an automatic transmission: slipping of clutches (jerks when switching), overheating of the torque converter, failure of solenoids (emergency mode of the automatic transmission).

How to check the condition of the oil in the gearbox?

For manual transmission RS5F32A no dipstick - the level is checked through inspection hole (on the side wall of the box). To assess the condition of the oil:

  1. Unscrew the control plug (key 10).
  2. Place the container - if the oil flows in a thin stream, the level is normal.
  3. Rate the color and smell:
    • 🟢 Light yellow/red — the oil is in good condition.
    • 🟠 Dark brown - replacement required.
    • ⚫ Black with metal shavings — The checkpoint needs repairs.

For automatic transmission RE4F03B checking is easier - there is a probe with marks COLD And HOT. However, what is important here is:

  • 🔹 Check level only on a warm gearbox (oil temperature 60–70°C).
  • 🔹 Oil should be between HOT marks (not to the maximum!).
  • 🔹 If the oil smells burning, this is a sign of overheating of the clutches - automatic transmission diagnostics are required.
💡

In automatic transmission Almera Classic You cannot check the oil level when it is cold - this will lead to underfilling and oil starvation when warming up.

Recommendations for choosing oil for different conditions

The choice of oil depends not only on the type of gearbox, but also on the climate and driving style. Let's consider the best options:

Operating conditions Manual transmission (RS5F32A) Automatic transmission (RE4F03B)
Moderate climate, quiet ride Nissan MT-XZ 75W-85 or Motul Gear 300 75W-90 Nissan Matic-S or Idemitsu ATF Type-J
Severe frosts (below −25°C) Liqui Moly 75W-80 (more fluid) Ravenol ATF J1 (stable at low temperatures)
Aggressive driving, traffic jams Castrol Syntrans Transaxle 75W-90 (enhanced protection) Aisin ATF AFW+ (high thermal stability)
High loads (trailer, mountains) Red Line MT-90 (semi-synthetic with additives) Oil change every 40 thousand km + additional automatic transmission cooling radiator

If you often travel with trailer or by mountain roads, gearbox oil Almera Classic better to change more often — every 50–60 thousand km for manual transmission and 40–50 thousand km for automatic transmission. Under such conditions, the box works under increased load, and the oil oxidizes faster.

FAQ: Frequently asked questions about gearbox oil Nissan Almera Classic

Is it possible to mix different oils in a gearbox?

B manual transmission mixing oils is allowed same viscosity grade and specification (For example, GL-4 75W-90 from different manufacturers). B automatic transmission mix oils absolutely not possible - this will lead to a chemical reaction and loss of ATF properties.

What to do if there is noise in the gearbox after changing the oil?

If noise (humming or crunching) appears immediately after replacement, possible reasons:

  • 🔹 Oil filled wrong viscosity (For example, 80W-90 instead of 75W-85).
  • 🔹 Got into the box dirty oil (did not wash the tray or magnets).
  • 🔹 Wear bearings or gears — the oil is not to blame, repairs are required.

Solution: drain the oil, flush the gearbox and fill with the correct fluid. If the noise remains, contact a diagnostician.

How often should you check the oil level in an automatic transmission?

In automatic transmission Almera Classic The oil level should be checked every 10–15 thousand km, as well as when the following symptoms appear:

  • 🔹 Jerks or delays when changing gears.
  • 🔹 Appearance vibrations at speeds of 60–80 km/h.
  • 🔹 Oil leaks (stains under the car in the checkpoint area).
Is it possible to use additives for gearboxes?

Additives for manual transmission (For example, Liqui Moly Getriebe-Oil-Additiv) may temporarily improve gear shifting, but will not eliminate synchronizer wear. For automatic transmission additives (type ATF Additive) are useless and even harmful - they can clog the filter or change the viscosity of the oil.

If the gearbox is already “crunching” or “kicking”, additives will not help - you need diagnostics and repair.

What kind of oil is poured into the gearbox? Almera Classic from the factory?

From factory to manual transmission flooded Nissan MT-XZ 75W-85 (article KE908-99932). B automatic transmission — Nissan Matic-S (article KE908-99931). However, after 10–15 years of operation, the original oil loses its properties, and it definitely needs to be replaced.
