Changing the gearbox oil Nissan Almera G15 - a procedure that many owners put off until the last minute, considering it secondary compared to engine oil. However ignoring the condition of the transmission fluid can lead to expensive repairs of an automatic transmission or manual transmission after 100–150 thousand km. In this article we will look at why even the “non-replaceable” oil in the Jatco JF015E variator requires updating every 60–90 thousand kmhow to choose the right liquid for Almera G15 (including restyled versions 2019–2023), and we will give step-by-step instructions with photos and videos.

Feature Almera G15 — use of two types of gearboxes: classic 4-speed automatic RE4F03B (on models before 2016) and CVT JF015E (since 2016). Each type requires different oils and replacement approaches. We will reveal the myths about “lifetime” fluid, explain why partial replacement is not always effective, and show how to save on service without risking the box. If you have already noticed jerks when switching, a hum or a burning smell, this article will help you diagnose the problem before visiting a car service center.

When to change the oil in a Nissan Almera G15 gearbox: official and real terms

Manufacturer Nissan in the manuals for Almera G15 indicates that the oil is in the automatic transmission and variator does not require replacement throughout the life of the vehicle. However, this approach is only relevant for “ideal” operating conditions: moderate climate, smooth roads and gentle driving style. In reality:

  • 🔥 For CVT JF015E: erste replacement is recommended after mileage 60–80 thousand km, then every 40–50 thousand km. With aggressive driving or frequent traffic jams, the interval is reduced to 30–40 thousand km.
  • ⚙️ For automatic transmission RE4F03B: optimal interval - 50–60 thousand km. This box is less sensitive to the quality of the oil, but its degradation accelerates the wear of the clutches.
  • 🌡️ Signs of urgent replacement: jerks when switching, delayed response to gas, extraneous noise, dark oil color (black or brown) with a burning smell.

It is important to consider that Almera G15 after restyling in 2019, it received an updated variator with changed settings of the control unit. For such models it is critical to use only original liquid NS-3 - analogues can cause belt slippage and an error P17F0 (viscosity mismatch).

⚠️ Attention: If you bought Almera G15 with mileage and don’t know the oil change history, don't take risks — make a complete replacement with flushing. Old oil may contain metal shavings that will clog the CVT solenoids.

  • Only when problems arise

What kind of oil to pour into the Nissan Almera G15 gearbox: original vs analogues

The choice of oil is a key point on which the resource of the box depends. For Almera G15 The following fluids are officially recommended:

Box type Original oil Acceptable analogues Replacement volume
CVT JF015E (since 2016) Nissan CVT Fluid NS-3 (KE909-99932) Idemitsu CVTF, Ravenol CVT, Motul Multi CVT 7.2–7.8 l (full replacement)
Automatic transmission RE4F03B (until 2016) Nissan Matic Fluid S (KE908-99931) Toyota T-IV, Castrol Transmax Dex-III 6.5–7.0 l
Manual transmission (all years) Nissan MT-XZ Fluid (KE916-99932) Liqui Moly Hypoid-Getriebeoil, Motul Gear 300 2.5–2.8 l

There are debates among car owners about compatibility NS-2 And NS-3 for the variator. It is strictly forbidden to use NS-2 in JF015E - this is oil for old variators (for example, Nissan Juke until 2014). NS-3 has improved anti-friction additives and high thermal stability, which is critical for Almera G15 with its compact box cooling radiator.

When choosing an analogue, pay attention to the specifications:

  • 🔧 For CVT: approval JWS 3324 or Nissan NS-3 on the packaging.
  • 🔄 For automatic transmission: compliance Dexron III or Mercon V.
  • ⚙️ For manual transmission: viscosity 75W-80 or 75W-90 (GL-4/GL-5).
⚠️ Attention: If you see the words "Universal CVT Fluid" on the canister without any indication NS-3, is a fake or a low-quality analogue. Such oils can cause the variator belt to slip after only 5–10 thousand km.
💡

Before purchasing oil, check its authenticity using the QR code on the canister. Original NS-3 from Nissan has a hologram and production date on the bottom of the container.

Preparing to change the oil in a Nissan Almera G15 gearbox: tools and consumables

To change the oil in the box yourself Almera G15 you will need:

- New oil (8 l for CVT, 7 l for automatic transmission)

- Box filter (for automatic transmission - 31726-31X00, for the variator - 31726-1XF0A)

- O-ring of the drain plug (11026-01M02)

- 10 mm wrench and 24 mm socket (for drain plug)

- Funnel with extension (for the variator - a special hose)

- Container for waste (minimum 8 l)

- Torque wrench (plug tightening torque - 35 Nm)

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

If you are planning complete oil change (and not partial), you will additionally need:

  • 🔌 Bleeding device (can be rented at a car service station).
  • 🔄 Two filters: coarse and fine cleaning (in the variator they are combined into one block).
  • 🧰 New pan bolts (it is recommended to replace, as the old ones may be deformed).

For CVT JF015E critical do not overfill the oil — excessive levels lead to foaming and loss of liquid properties. Check the level using the dipstick (there are marks on the box COLD And HOT) or through the diagnostic hole (on some versions there is no dipstick).

How to check the oil level without a dipstick?

On CVTs without a dipstick, the level is checked through the inspection hole on the pan. To do this:

1. Warm up the box to 50–60°C (drive 10–15 km).

2. Raise the car on a lift (it must be level!).

3. Unscrew the control plug (10 mm wrench) - oil should drip in a thin stream. If it flows heavily, the level is high; if it does not drip, add through the filler hole.

Step-by-step instructions: how to change the oil in a Nissan Almera G15 gearbox

Let's look at the process using an example variator JF015E (for automatic and manual transmissions the steps are similar, but with nuances). The whole process will take 2–3 hours.

Step 1: Drain the old oil

1. Warm up the engine and gearbox to operating temperature (50–60°C). To do this, it is enough to drive 10–15 km.

2. Raise the car on a lift or drive it into a pit. Make sure the machine is level - this is critical for proper draining.

3. Place a container under the drain plug (it is located on the tray of the box). Unscrew the plug with a 24 mm wrench. Be careful - the oil will be hot!

4. Wait until it drains completely (about 10–15 minutes). Only ~40% of the oil (3–3.5 l) is drained from the variator, the rest remains in the torque converter.

Step 2: Replace the filter and wash the pan

1. Unscrew the pan bolts (10 mm wrench) and carefully remove it. There will be another ~0.5 liters of oil inside.

2. Remove the old filter (it is secured with 3 bolts). Pay attention to the condition of the magnets on the pallet - if there are a lot of metal shavings on them, this is a sign of wear on the bearings.

3. Clean the tray and magnets from deposits. Use Just a lint-free cloth and box cleaner (For example, Liqui Moly Getriebe-Reiniger).

4. Install a new filter and O-ring. Tighten the bolts crosswise to a torque of 10 Nm.

Step 3: Add new oil

1. Fill in new oil through the filler hole (located on top of the box, under the hood). For a partial replacement, 4–4.5 liters is enough.

2. Start the engine and let it idle for 2-3 minutes. Switch the gearbox selector through all positions (P-R-N-D) with a delay of 5 seconds in each.

3. Check the oil level using the dipstick or through the inspection hole. Top up if necessary.

4. Repeat the drain-fill procedure 1-2 more times (for a complete replacement). This will renew 80–90% of the oil in the system.

⚠️ Attention: After changing the oil in the variator be sure to reset the adaptations through a diagnostic scanner. Otherwise, the box will work jerkily for the first 100–200 km. To do this, connect to the block TCM and follow the procedure Variator Learning.
💡

Complete oil change in the variator Almera G15 requires 3–4 drain-fill cycles. Don’t skimp on volume - it’s better to buy 8 liters of oil and do everything efficiently than to repair the box later.

Partial vs complete replacement: which is better for the Nissan Almera G15?

There is no consensus among car owners about the method for changing the oil in the box. Almera G15 preferable. Let's look at the pros and cons of each:

Criterion Partial replacement Complete replacement
Cost ✅ Cheaper (requires 4–5 liters of oil) ❌ More expensive (needs 7–8 l + device)
Efficiency ❌ Only 40–50% of the oil is renewed ✅ Replacement of 90–95% fluid
Lead time ✅ 1–1.5 hours ❌ 2.5–3 hours
Risk for the box ✅ Minimum (no pressure) ⚠️ There is a risk of damage to the torque converter if improperly pumped
Recommendation Suitable for prevention every 30 thousand km Mandatory when purchasing a used car or mileage >100 thousand km

Many services offer "full replacement" without the device — multiple drain-fill with oil passing through the system. This method is cheaper, but less effective: up to 10% of the old fluid remains in the torque converter and radiator. For Almera G15 with variator JF015E best option:

  • 🔄 Up to 80 thousand km: partial replacement every 30–40 thousand km.
  • 🔧 After 100 thousand km: complete replacement with flushing the pan and replacing filters.

If you choose a hardware replacement, make sure the service uses special equipment for variators (For example, Launch CReader or Bosch KTS). Conventional automatic transmission devices can create excess pressure and damage the solenoids.

Common mistakes when changing oil and how to avoid them

Even experienced car owners make mistakes that reduce the life of the box. Almera G15. Here are the most critical of them:

  • 🚫 Using the wrong oil: fill Dexron III instead of NS-3 or vice versa. This leads to slippage of the variator belt or torque converter jamming.
  • 🔧 Incorrect tightening torque: An overtightened drain plug deforms the pan, and a weak tightening leads to a leak. moment for Almera G15 — 35 Nm.
  • 🌡️ Checking the level when cold: The oil in the variator expands when heated. If you fill according to the mark COLD, after warming up the level will be higher than normal.
  • 🔄 Ignoring adaptations: after changing the oil in the variator, you need to reset the control unit settings. Without this, the box will be “stupid” when switching.
  • 🧹 Uncleaned pan: if you do not wash the magnets and the tray from chips, they will quickly clog the new filter.

A separate problem - fake oil. There are many canisters on the market with the inscription NS-3, which actually contain cheap ATF. How to recognize the original:

  • 🏷️ Caption Nissan CVT Fluid NS-3 should be raised (not printed).
  • 🔍 The lid of the canister has protection against opening (the “ears” break when first opened).
  • 📌 The production date is stamped on the bottom of the canister (format YYMMDD).
⚠️ Attention: If after changing the oil in the variator Almera G15 appeared noise when cold (the first 1-2 minutes), this is normal - the new oil is more viscous. But if the noise does not go away after warming up, it means the level was overfilled or low-quality oil was used.

The cost of changing the oil in a Nissan Almera G15 gearbox: service vs independently

Box oil change price Almera G15 depends on box type, replacement method and region. Average prices for 2026:

Box type Partial replacement (service) Complete replacement (service) Do it yourself (consumables)
CVT JF015E 3 500–5 000 ₽ 6 000–9 000 ₽ 4,000–5,500 ₽ (oil + filter)
Automatic transmission RE4F03B 2 800–4 000 ₽ 5 000–7 000 ₽ 3 000–4 500 ₽
Manual transmission 1 500–2 500 ₽ — 1 200–2 000 ₽

The savings when replacing yourself are obvious, but consider the hidden costs:

  • 🔧 Tool: if you don’t have a 24 mm socket or a torque wrench, purchasing them will cost 1,500–2,000 rubles.
  • 🚗 Lift/pit: renting a box in a garage cooperative costs 300–500 RUR/hour.
  • 🔄 Waste disposal: the service accepts it for free, but you will have to take it yourself to the reception point (sometimes paid).

If you decide to contact the service, choose specialized centers according to Nissan or variators. Avoid general service stations where they may:

  • 🛑 Fill in a cheap analogue instead of the original.
  • 🔧 Do not replace the filter (save 1,000–1,500 ₽).
  • 📉 Do not reset adaptations (which will cause the box to twitch).
💡

Do-it-yourself oil change in the box Almera G15 justified if you have experience and tools. For CVT JF015E It’s better to trust the service - errors during replacement cost repairs from 50,000 ₽.

FAQ: Frequently asked questions about changing the oil in a Nissan Almera G15 gearbox

Is it possible to mix different oils in the Almera G15 variator?

No, mix NS-3 with other oils (including NS-2) is absolutely not possible. This will lead to a chemical reaction of the additives, foaming and loss of lubricating properties. If you need to add oil, use only the original KE909-99932.

How often do you need to change the oil in the Almera G15 manual transmission?

For manual transmission Almera G15 official replacement interval - every 90 thousand km. However, when operating in difficult conditions (city traffic jams, off-road), reduce the interval to 60–70 thousand km. Mechanics are less sensitive to oil quality, but its degradation accelerates the wear of synchronizers.

What will happen if you don’t change the oil in the Almera G15 variator?

The consequences depend on the mileage:

  • 100–150 thousand km: increased fuel consumption, jerks during acceleration, bearing noise.
  • 150–200 thousand km: Belt slippage, error P17F0, transition to emergency mode.
  • 200+ thousand km: destruction of bearings, jamming of the torque converter (repair ~100,000 ₽).

CVT JF015E very sensitive to oil quality - its repair costs 3-5 times more than regular replacement.

What kind of oil is poured into the Almera G15 box from the factory?

From factory to CVT JF015E is poured Nissan CVT Fluid NS-3, in automatic transmission RE4F03B — Nissan Matic Fluid S. In manual transmission it is used Nissan MT-XZ Fluid (viscosity 75W-80). These oils are considered “irreplaceable”, but in practice their properties deteriorate after 50–60 thousand km.

Is it possible to drive with a slightly lower oil level in the variator?

Short term (1-2 days) - yes, but no more than 10–15% of the norm. Long-term driving at low levels leads to:

  • Overheating of the belt and cones.
  • Accelerated wear of bearings.
  • Loss of pressure in the valve body (jerks when switching).

If the level has dropped due to a leak, do not add oil without eliminating the cause - this could be a crack in the radiator or wear of the oil seal.
