Partial oil change in the <em>Nissan Almera Classic</em> automatic transmission: when is it necessary and how to do it correctly

Automatic transmission Nissan Almera Classic (body N16) is a reliable unit, but only subject to timely maintenance. Many owners mistakenly believe that partial oil change in automatic transmission - this is a half-measure that does not give a real effect. In fact, this method allows you to extend the life of the transmission by 50–80 thousand km, if carried out regularly and with the right approach.

In this article we will look at when you really need a partial replacement (and when it’s full), what kind of oil to pour into Almeru Classicwhat tools you will need and how to avoid mistakes. You will also find step-by-step instructions with photos, a comparative table of oils and answers to frequently asked questions. If your automatic transmission starts to “kick”, there are jerks or the oil has darkened - this information will help you save on expensive repairs.

When is a partial oil change needed in an automatic transmission? Nissan Almera Classic?

Manufacturer Nissan states that the oil is in the automatic transmission RE4F03A (installed on Almera Classic with engines 1.5 And 1.8) is designed for the entire service life. However, in practice, this statement is true only for ideal operating conditions: moderate climate, absence of traffic jams and a gentle driving style. In reality, even partial replacement is required:

• 🔧 When running 60–80 thousand km - if the oil has never been changed (even if the car doesn’t “kick”).
• 🚗 After 100–120 thousand km - if the previous replacement was partial.
• ⚠️ When symptoms appear:
  • Jerks when changing gears (especially from 1st to 2nd).
  • Power-on delays Drive or Reverse.
  • Darkening of the oil (checked with a dipstick) or a burning smell.
• 🔄 After purchasing a used car - if there are no documents about replacement.

Partial replacement is suitable if the oil is not critically contaminated (no metal shavings or black color). If large wear particles are found in the pan or the oil smells burnt, you will need complete replacement with flushing (and possibly automatic transmission repair).

⚠️ Attention: If after changing the oil the jerking does not disappear and metal dust is visible on the dipstick, this is a sign of wear on the clutches or solenoids. In this case, partial replacement will only temporarily delay the repair.

What kind of oil to fill in automatic transmission Nissan Almera Classic?

Box RE4F03A sensitive to oil type. Using the wrong fluid will lead to clutch slippage, overheating and accelerated wear. Official recommendations Nissan:

• 📌 Original oil: Nissan Matic Fluid D (art. KE908-99931) or Nissan Matic Fluid J (art. KE909-99932) - for boxes after 2006.
• 🔄 Analogs (full):
  • Idemitsu ATF Type-J (Japan).
  • Ravenol ATF J Fluid (Germany).
  • Motul Multi ATF (universal, but suitable for partial replacement).

Automatic transmission oil volume Almera Classic — 7.2 liters (full), but with partial replacement it only drains 3.5–4 liters (about 50%). Important: Do not mix different types of oils (For example, Matic D And Matic J) - this will cause a chemical reaction and damage the seals.

Oil type	Article	Volume for partial replacement	Notes
Nissan Matic Fluid D	KE908-99931	4 liters	For boxes before 2006
Nissan Matic Fluid J	KE909-99932	4 liters	For boxes after 2006
Idemitsu ATF Type-J	30450-54055	4 liters	The best analogue in terms of price/quality
Ravenol ATF J Fluid	4014835755106	4 liters	High temperature stability

Critically important: if the box is already filled with Matic J, you can't go back to Matic D - this will lead to destruction of the friction discs. When purchasing a used car, check with the previous owner to find out what kind of oil was used. If there is no information, it’s better to do it complete replacement with washing.

Tools and consumables for replacement

For partial oil change in automatic transmission Nissan Almera Classic You don’t need a professional tool, but you will need:

• 🔧 Key on 10 mm - for the drain plug.
• 🔧 Key on 14 mm — for the pallet bolts (if you plan to remove it).
• 🛢 Funnel with a long spout (or hose Ø8–10 mm).
• 🧴 Container for draining oil (minimum 5 liters).
• 🧰 New automatic transmission filter (art. 31726-31X00) — if you remove the pallet.
• 🧴 Sealant for the pallet (for example, Loctite 574 or Permatex 81160).
• 🧤 Gloves and rags.

If you do not plan to remove the pan, it is not necessary to change the filter (but then the effect of the replacement will be lower). For a complete procedure it is better to buy replacement kitwhich includes:

• 📦 Oil (4 liters).
• 🔧 Pallet gasket (art. 31397-31X00).
• 🧻 Automatic transmission filter.
• 🔑 New drain plug with sealing ring (art. 31377-31X00).

⚠️ Attention: If the drain plug has metal shavings or the magnet is covered with black deposits, this is a sign of critical wear of the box. In this case, partial replacement will not help; diagnostics are needed.

The drain plug is not broken (check the threads)

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

The procedure takes about 1–1.5 hours. It’s better to do it on a pit or a lift, but you can get by with a jack (with safety net!). Important: the box must be warmed up to operating temperature (drive 10-15 km before replacing).

Step 1: Drain the old oil

1. Turn off the engine and put the car on the handbrake.
2. Place a container under the drain plug (it is located on the automatic transmission pan).
3. Key on 10 mm unscrew the plug. Be careful - the oil will be hot!
4. Wait until the maximum amount of oil has drained (usually 3.5–4 liters).

Step 2: Replace the filter (optional)

If you decide to remove the pallet:

1. Unscrew all pan bolts (key on 14 mm).
2. Carefully remove the pan - ~0.5 liters of oil will remain in it.
3. Replace the filter (art. 31726-31X00) and clean the magnets from chips.
4. Install a new pan gasket using a thin layer of sealant.

Step 3: Add new oil

1. Tighten the drain plug (tightening torque - 35 Nm).
2. Insert a funnel into the filler hole (next to the dipstick).
3. Fill in exactly as much oil as was drained (usually 3.5–4 liters).
4. Start the engine and warm up the box (switch all modes P-R-N-D with a delay of 5 seconds).
5. Check the level with a dipstick - it should be between MIN And MAX for hot.

Important: Do not add oil “by eye” - overfilling is just as harmful as underfilling! If the level is higher MAX, the excess must be pumped out with a syringe through the filler hole.

Typical mistakes when changing automatic transmission oil

Even experienced car owners make mistakes that negate all the benefits of replacement. Here are the most common:

• 🚫 Using the wrong oil. For example, fill Dexron III instead of Matic J leads to clutch slippage.
• 🚫 Unheated box. If the oil is cold, only 2–2.5 liters are drained instead of 3.5–4.
• 🚫 Overfilling or underfilling. Both options lead to foaming and accelerated wear.
• 🚫 Ignore the filter. If you do not change the filter, dirt will quickly clog the new channels.
• 🚫 Mixing oils. Even if both oils are from Nissan, but of different types (D And J) - this is unacceptable.

Another common mistake is incorrect level check. Automatic transmission dipstick Almera Classic has two zones: COLD (cold) and HOT (hot). You need to check the level only on a warm box (oil temperature ~60–80°C).

⚠️ Attention: If, after the replacement, vibrations appeared or the box began to “kick”, it is possible that low-quality oil was filled in or the level was incorrect. In this case, you need to repeat the washing procedure.

What to do if you overfilled the oil?

If the level is higher MAX by 5–10 mm, no big deal - the excess will burn out. If the overflow is significant (more than 200 ml), you need to pump out the excess with a syringe through the filler hole. Driving with overflow is dangerous: the oil foams, the pressure drops, and the transmission begins to “stupid.”

How much does a partial automatic transmission oil change cost? Nissan Almera Classic?

The cost depends on whether you do the work yourself or contact a service. Let's consider both options:

Expense item	On your own	In service
Oil (4 liters)	2 500–4 000 ₽	3,000–5,000 ₽ (with extra charge)
Automatic transmission filter	800–1 200 ₽	1 500–2 000 ₽
Pan gasket	300–500 ₽	Included in the cost of work
Work (drain/fill)	0 ₽	1 500–2 500 ₽
Total	3 600–5 700 ₽	6 000–9 500 ₽

The service often offers automatic transmission flushing (cost ~3,000 ₽). For Almera Classic it is only needed if the oil is black or has a burning smell. In other cases, 2–3 partial replacements with an interval of 500–1,000 km are sufficient.

Advice: If your budget is limited, buy the oil and filter yourself, and only pay for the work at the service center. This way you will save 20-30%.

Partial vs full replacement: which is better for Nissan Almera Classic?

Many argue which is more effective: partial replacement or complete (hardware). Let's look at the pros and cons of each method:

• ✅ Partial replacement:
  • Cheaper (2–3 times).
  • There is less risk of “washing away” dirt and clogging the channels.
  • You can do it yourself.
• ❌ Cons:
  • Only 50% of the oil is replaced.
  • The effect is temporary (lasts for 30–50 thousand km).
• ✅ Full replacement (hardware):
  • 90–95% of oil is replaced.
  • The effect lasts longer (60–80 thousand km).
• ❌ Cons:
  • Expensive (10–15 thousand rubles).
  • There is a risk of “stirring up” the sediment in the pan.
  • Requires special equipment.

Conclusion: For Almera Classic with mileage up to 150 thousand km is optimal partial replacement every 60 thousand km. If the mileage is higher or the oil is in terrible condition, it’s better to do it complete replacement with flushing (but only in a trusted service!).

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

Is it possible to fill in non-original oil (for example, Motul or Liqui Moly)?

Yes, but only if it is certified according to the standard Nissan Matic J. For example, Idemitsu ATF Type-J or Ravenol ATF J Fluid - complete analogues. But universal oils (Dexron VI, ATF+4) cannot be filled - they are not compatible with clutches RE4F03A.

How much oil is drained during a partial change?

Usually 3.5–4 liters (about 50% of the total volume). If less than 3 liters drained, the box was not heated enough or the oil was too thick (you need to repeat the procedure after warming up).

Do I need to change the filter during a partial replacement?

Optional, but desirable. If the filter is clogged, the new oil will quickly become contaminated. The cost of the filter (~1,000 ₽) is justified if you plan to drive the car for a long time.

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

After 100–120 thousand km without replacement, the oil loses its properties: pressure drops, clutches slip, and jerking appears. The result is wear of the solenoids, locking of the torque converter and major repairs (from 50 thousand rubles).

Is it possible to mix Matic D And Matic J?

No! These oils have different additive packages. Mixing will lead to a chemical reaction, destruction of seals and slippage of clutches. If you don’t know what’s flooded, do a complete replacement.
