Nissan Almera G15 with an automatic transmission is a popular choice among budget sedan owners, but many people forget that The automatic transmission requires maintenance no less often than the engine.. In this article we will look at how to properly change the oil in an automatic transmission. Almera G15 (including restyled versions 2016–2023) to avoid costly repairs. We will not limit ourselves to standard advice - we will reveal unique nuances of this particular model, which are often missed even in service manuals.

You will learn what oil to fill (and why Nissan Matic S not always the best choice), how to check the level without a dipstick, what tools are needed for a complete replacement with washing, and why a partial replacement can harm the box. We will also look at typical errors that cause jerking or kicking of the transmission after replacement.

Why change the oil in an automatic transmission? Almera G15 critical: consequences of ignoring

Owners Nissan Almera G15 It is often believed that automatic transmission RE0F10A (installed on most versions) "maintenance free" is a myth spread by dealers. Actually the manufacturer recommends changing the oil every 60–90 thousand km, but in Russian conditions (traffic jams, low temperatures, aggressive driving) this interval should be reduced to 40–50 thousand km.

What happens if you ignore the replacement:

  • 🔥 Oil overheating: when slipping or towing, the temperature in the automatic transmission rises to 120–140°C, and the old oil loses its viscosity and lubricating properties.
  • ⚙️ Friction wear: wear products clog the valve body and solenoids, which leads to delays when switching.
  • 💥 Torque converter failure: in 80% of cases, its failure is associated with contaminated oil.
  • 🚨 Automatic transmission emergency mode: The transmission begins to “kick” or blocks shifts above 3rd gear.

Feature Almera G15: its automatic transmission is sensitive to oil quality. For example, the use of universal ATF fluids (such as Dexron III) instead of specialized (Nissan Matic S or Idemitsu ATF Type-J) accelerates wear by 2–3 times. At the same time, even the original oil loses its properties after 50 thousand km - tested by laboratory tests.

⚠️ Attention: If it appears in the oil burnt smell or metal shavings, partial replacement will no longer help - a complete flushing with dismantling the pan and replacing the filter is required. Otherwise, new portions of oil will mix with dirt, and the problem will worsen.

What kind of oil to fill in automatic transmission Nissan Almera G15: comparison of options

The choice of oil is key. Manufacturer indicates Nissan Matic S (article KE908-99932), but this is not always the best option. Let's consider alternatives taking into account climatic conditions:

Oil brand Compatible with RE0F10A Pros Cons Price for 1 l (2026)
Nissan Matic S 100% Original, optimal viscosity for cold starts Expensive, counterfeit, quickly loses properties when overheated 1 200–1 500 ₽
Idemitsu ATF Type-J 98% Better alternative to the original, more stable at high temperatures Difficult to find in small towns 900–1 100 ₽
Mobil ATF 3309 95% Good wear protection, suitable for aggressive riding May cause hard shifts in cold temperatures below -25°C 700–900 ₽
Toyota T-IV 90% Cheaper than the original, suitable for partial replacement Not recommended for complete replacement - seals may leak 600–800 ₽

For regions with frosts below -30°C, it is better to choose Idemitsu ATF Type-J - It remains fluid at extreme temperatures. If your budget is limited, you can use Mobil ATF 3309, but only on condition partial replacement (no more than 40% of volume). It is risky to do a complete replacement with cheap analogues: for example, Toyota T-IV may cause leaks through the pan gasket due to a different additive formula.

Oil volume to change:

  • 🔧 Partial replacement: 3–3.5 l (drain through the plug).
  • 🔄 Complete replacement with flushing: 7–8 l (requires a machine or multiple drain and fill).
  • 🛠️ Replacement with disassembly of pan and filter: 4.5–5 l + 0.5 l for rinsing.
⚠️ Attention: Never mix oils from different manufacturers! For example, Nissan Matic S And Toyota T-IV have incompatible additive packages. If you don't know what was uploaded earlier, do it complete replacement with flushing.

Tools and materials: a complete checklist for replacement

To change the oil in an automatic transmission Almera G15 you will need a specific tool. Here's what you need to prepare:

10mm wrench (for drain plug)

14 mm wrench (for filler plug)

TORX T30 socket (for pallet on some versions)

Torque wrench (tightening torque 35–40 Nm)

New pan gasket (part number 31397-31X01) or sealant (Loctite 574)

Automatic transmission filter (article 31726-31X00 or equivalent)

Funnel with extension (neck diameter 12 mm)

Drain container (minimum 5 l)

Gloves and lint-free rags

Scanner for resetting adaptations (for example, Launch X431) -->

Pay special attention pallet gasket. Original (31397-31X01) costs about 800 ₽, but it can be replaced with a high-quality analogue from Elring or Victor Reinz. Use sealant only as a last resort - it can clog the oil receiver if applied carelessly.

Automatic transmission filter changing necessarily with a complete replacement. On Almera G15 fine filter installed (31726-31X00), which becomes clogged with wear products after 60 thousand km. If you ignore replacing it, the new oil will quickly become contaminated.

To reset automatic transmission adaptations after changing the oil, you will need a diagnostic scanner. Without this, the box may not work correctly for the first 100–200 km (jerks, delays). Suitable:

  • 📱 Launch X431 Pro (from 25 thousand ₽) - professional option.
  • 🔌 ELM327 + Torque Pro software (from 1.5 thousand ₽) - a budget solution, but it requires skills.
  • 🚗 Official dealer (reset service costs 1–1.5 thousand ₽).
💡

Before changing the oil, warm up the automatic transmission to operating temperature (60–70°C). To do this, drive 10–15 km or let the engine idle for 20–30 minutes with the mode turned on D. This will allow you to drain out as much of the old oil as possible.

Step-by-step instructions: how to change the oil in an automatic transmission Almera G15

Let's consider two replacement options: partial (for prevention) and full (with washing and replacing the filter).

Option 1: Partial replacement (30–40% volume)

Suitable if the oil is light and without a burnt smell, and the mileage after the last change does not exceed 40 thousand km.

  1. Draining old oil:

    Place the machine on a pit or lift. Remove the crankcase protection (if equipped). Unscrew the drain plug with a 10 mm wrench. Place the container and the oil will drain for 5–10 minutes. Pay attention to the color and presence of metal shavings.

  2. Washing the pan:

    If you decide not to remove the pan, skip this step. If you remove it, carefully unscrew the bolts (start from the corners) and drain the remaining oil. Clean the magnets and the bottom of the tray from deposits. Check the condition of the gasket.

  3. Filling with new oil:

    Screw in the drain plug. Fill in new oil through the filler hole (14 mm plug, next to the right CV joint). Use a funnel with an extension. Volume - 3–3.5 l. Tighten the plug with a torque of 35 Nm.

  4. Level check:

    Start the engine, warm up the automatic transmission (switch all modes with a delay of 5 seconds). The level is checked through the inspection hole - oil should drip at a temperature of 60°C.

Option 2: Complete replacement with flushing (recommended)

It is necessary if the oil is dark, has a burning smell, or the mileage since the last change exceeds 60 thousand km.

  1. Draining old oil (same as partial replacement).
  2. Removing the pan and replacing the filter:

    Unscrew all pan bolts (TORX T30). Remove the filter (pliers may be required). Install a new filter and gasket. Tighten the bolts crosswise to a torque of 10 Nm.

  3. Flushing the system:

    Connect a washing device (for example, Wynn’s Transerve II) or perform multiple drain-fill: fill in 3 liters of new oil, start the engine, drain, repeat 2-3 times.

  4. Filling the full volume:

    Pour in 4.5–5 liters of oil. Warm up the automatic transmission, check the level. Top up if necessary.

  5. Resetting adaptations:

    Connect the scanner and reset the automatic transmission parameters (in the menu Transmission → Adaptations Reset).

After a complete replacement, avoid sudden acceleration and towing for the first 50–100 km - the oil should be evenly distributed throughout the system.

💡

Complete automatic transmission oil change Almera G15 costs 2–3 times less than repairing a box after it fails. Average cost of automatic transmission overhaul RE0F10A — 80–120 thousand ₽.

Common mistakes when changing oil and how to avoid them

Even experienced technicians make mistakes that lead to automatic transmission failure. Here are the most common:

  1. Overfilling or underfilling oil:

    Both are dangerous. When underfilling the pump will trap air, which will lead to oil starvation. When overflow the oil will foam, lose its properties, and the pressure in the system will drop. Check the level strictly at a temperature of 60°C!

  2. Using the wrong oil:

    For example, fill Dexron VI instead of Nissan Matic S will lead to slipping of the clutches. Always check the compatibility chart.

  3. Forgetting to replace the filter:

    The filter becomes clogged with wear products and stops passing oil. If you do not change it, the new oil will quickly become contaminated.

  4. Incorrect tightening torque:

    A drain plug or pan that is tightened to more than 40 Nm may crack. Weak tightening will lead to leakage.

  5. Ignoring reset adaptations:

    After changing the oil, the automatic transmission “does not understand” its viscosity and operates in emergency mode. Resetting adaptations is required!

Another common mistake is washing automatic transmission with solvents (for example, kerosene). This is strictly prohibited! Solvents destroy seals and gaskets, and their residues mix with new oil, worsening its properties.

⚠️ Attention: If after changing the oil there are jerks when switching, check:
  • Oil level (possibly underfilled or overfilled).
  • Oil quality (fake or incompatible composition).
  • Have you reset the adaptations (without this the box “learns” 100–200 km).

If the problem persists, contact service - the valve body may be clogged.

How to check the oil level in an automatic transmission Almera G15 without dipstick

B Nissan Almera G15 There is no dipstick for checking the oil level in the automatic transmission - it is used instead inspection hole. Here's how to check the level correctly:

  1. Warm up the automatic transmission:

    Drive 10–15 km or run the engine for 20 minutes with the mode on D. The oil temperature should be 60–70°C (can be checked with a scanner or thermometer).

  2. Place the machine on a level surface:

    A tilt of more than 2° will distort the readings. Turn off the engine.

  3. Unscrew the control plug:

    It is located on the automatic transmission pan next to the drain plug (14 mm wrench). In normal condition, the oil should drip or ooze slightly. If it doesn’t drip, the level is low, if it flows in a stream, it’s overflowing.

  4. Add oil if necessary:

    Use a funnel with an extension. Pour 100 ml at a time, checking the level. Tighten the plug with a torque of 35 Nm.

If the oil is dark or has a burning smell, a complete replacement is required. Normal color is red or light brown.

What to do if the oil foams?

Foam in automatic transmission oil Almera G15 - a sign of air ingress or overflow. This is dangerous, as it leads to a drop in pressure and slipping of the clutches. To fix the problem:

  1. Warm up the box to 60°C.
  2. Drain excess oil through the inspection hole.
  3. If the foam remains, a complete replacement with washing is required.
  4. Check the automatic transmission breather (it may be clogged, which creates a vacuum).

How much does it cost to change automatic transmission oil? Almera G15: comparison of options

The cost of replacement depends on the method and materials used. Let's consider the prices for Moscow and the regions (2026):

Replacement type Cost of work (₽) Cost of materials (₽) Total (₽) Time (hours)
Partial replacement (drain-fill) 1 500–2 500 3,000–4,500 (oil 3–4 l) 4 500–7 000 1–1.5
Complete replacement with flushing (hardware) 3 500–5 000 7,000–9,000 (8 l oil + filter) 10 500–14 000 2–3
Complete replacement with pallet disassembly 4 000–6 000 8,000–10,000 (5 l oil + filter + gasket) 12 000–16 000 3–4
Self-replacement 0 4,000–6,000 (oil + filter + gasket) 4 000–6 000 3–5

Replacing it yourself is cheaper, but requires tools and skills. For example, without a torque wrench it’s easy to tighten the plug, and without a scanner it’s easy to forget to reset the adaptations. If you are not confident in your abilities, it is better to contact the service.

Where to replace:

  • 🔧 Official dealer: expensive (15–20 thousand rubles), but the work is guaranteed. Original materials are used.
  • 🏁 Specialized automatic transmission service: optimal option (10–14 thousand rubles). Masters know the nuances Almera G15.
  • 🛠️ Garage workshops: cheap (5-8 thousand rubles), but there is a high risk of errors (for example, they won’t reset the adaptations).

FAQ: Frequently asked questions about changing automatic transmission oil Nissan Almera G15

Is it possible to fill in oil of a different brand if there is no original one? Nissan Matic S?

Yes, but only compatible analogues: Idemitsu ATF Type-J or Mobil ATF 3309. Do not use under any circumstances Dexron II/III or universal ATF - they do not meet the requirements RE0F10A.

How often do you need to change the oil if the car is used only in the city?

In city mode (traffic jams, frequent stops), the oil ages faster. Recommended interval - every 35–40 thousand km, even if the manufacturer indicates 60 thousand km.

What happens if you don’t change the automatic transmission oil? Almera G15?

After 80–100 thousand km without replacement:

  • There will be jerks when switching.
  • Fuel consumption will increase (up to 1–1.5 liters per 100 km).
  • The box will go into emergency mode (locked in 3rd gear).
  • Repairs will be required (replacement of clutches, solenoids) costing from 50 thousand rubles.

Is it necessary to flush the automatic transmission when changing the oil?

If the oil is dark or has a burning smell - yes. Flushing removes deposits from the valve body and channels. For Almera G15 It is better to use the multiple drain-fill method (3-4 cycles) than hardware flushing (risk of damage to the seals).

Is it possible to drive with underfilled automatic transmission oil?

No! Underfilling even by 200–300 ml leads to oil starvation of the pump, which causes:

  • Accelerated bearing wear.
  • Clutch slippage.
  • Box overheating.

At the first signs (jerking, noises), add oil and check for leaks.
