Nissan Almera G15 - popular sedan with automatic transmission RE0F10A (Jatco JF015E), which, with proper maintenance, lasts 200+ thousand km. But many owners neglect to change the automatic transmission oil, believing that it is “filled for its entire service life.” This is a dangerous misconception: over time, the liquid loses its properties, accumulates wear products and leads to jerks, jolts or complete failure of the box.

A partial oil change is a compromise between a complete oil change (expensive and requires special equipment) and completely ignoring the problem. In this article we will look at when a partial replacement is neededwhat kind of oil to put in Almera G15, how to carry out the procedure yourself and what mistakes can cost you automatic transmission repair.

When is a partial oil change needed in an Almera G15 automatic transmission?

Manufacturer Nissan does not indicate clear automatic transmission oil change intervals for Almera G15, but experts recommend focusing on:

  • 📅 Mileage 60–80 thousand km — if the car is operated in city mode (frequent traffic jams, irregular rhythm).
  • ⏳ 4–5 years - even with low mileage, the oil ages due to oxidation and loss of additives.
  • ⚠️ Onset of symptoms: jerks when switching, delays, extraneous noise or vibration.
  • 🔧 After buying a used car — if the service history is unknown, it is better to play it safe.

Partial replacement (draining 30–50% of the volume) is relevant if:

  • 💰 There is no budget for a complete replacement (8-12 liters of oil and flushing will be required).
  • 🚗 The car is operated in a gentle mode (highway, rare traffic jams).
  • 🔄 You plan to repeat the procedure after 20-30 thousand km to gradually update the oil.
⚠️ Attention: If the oil is in the automatic transmission Almera G15 black, smells like burning or contains metal shavings, partial replacement won't help - a full diagnosis and possibly box repair is required.
📊 How often do you change the automatic transmission oil?
  • Every 40–60 thousand km
  • Every 80–100 thousand km
  • Only when problems arise
  • Never changed

What kind of oil to pour into the automatic transmission of Nissan Almera G15

Box RE0F10A in Almera G15 demanding on oil quality. Official Recommended Product - Nissan Matic Fluid S (article KE908-99931). This is a synthetic oil with a unique additive package, designed specifically for automatic transmissions. Nissan with a “wet” clutch.

Alternative options (specification compatible) JWS 3309):

Brand Oil name Article Volume (l) Notes
Idemitsu ATF Type-J 30450-5M200 4 Complete analogue Matic S, often used in services
Ravenol ATF JWS 3309 4014835734817 1 High temperature stability, suitable for hot climates
Motul Multi ATF 105777 1 Versatile, but requires more frequent replacement
ZIC ATF SP-IV 162627 4 Budget option, but not recommended for long-term use

Important: mix oils of different brands in automatic transmissions Almera G15 is strictly prohibited - this may cause foaming and loss of lubricating properties. If you are not sure about the previous oil, it is better to carry out a complete change.

Automatic transmission oil volume Almera G15:

  • 🔧 Full volume: ~7.5 liters (including torque converter).
  • 🔄 Partial replacement: ~3–3.5 liters are drained (depending on the oil temperature).
💡

Before purchasing oil, check its authenticity! On cans Nissan Matic S there must be a hologram and a serial number, which can be checked on the manufacturer’s website.

Tools and preparation for an oil change

For partial oil change in automatic transmission Almera G15 you will need:

Fresh oil (4–5 liters)|New automatic transmission oil filter (part number 31728-3MX0A)|Pan gasket (31397-3MX0A)|10 mm wrench and 24 mm socket for drain plug|Funnel with long spout and hose with a diameter of 8-10 mm|Drain container (minimum 5 l)|Lint-free rag and gloves|Torque wrench (optional, for precise tightening)-->

Also prepare the car:

  1. Warm up the automatic transmission to operating temperature (drive 10–15 km or let the engine run for 10 minutes with the selector switching in all modes).
  2. Place the machine on a flat surface (pit, overpass or lift).
  3. Stop the engine and apply the handbrake.
⚠️ Attention: Do not replace with a cold one! The cold oil does not drain completely, and sediment remains in the pan. You also risk getting burned - the temperature of the oil in the automatic transmission after warming up reaches 80–90°C.

If you plan to replace the automatic transmission filter (which is highly recommended with a mileage of over 100 thousand km), be prepared for additional difficulties: you will need to remove the pan, which increases the risk of damage to the gasket. In some cases, the filter is glued to the body of the box; you will have to carefully pry it off with a flat screwdriver.

Step-by-step instructions for a partial oil change

The procedure takes 1.5–2 hours and consists of several stages:

1. Drain old oil

Algorithm of actions:

  1. Place a container under the drain plug (it is located on the automatic transmission pan closer to the rear of the car).
  2. Unscrew the plug with a 24 mm wrench. Be careful - the oil will come under pressure!
  3. Wait until the oil stops dripping (usually ~3 liters drains).
  4. Wipe off any metal shavings from the plug and magnet (if present). Heavy deposits of chips are a sign of wear on the clutches!

2. Replacing the filter and gasket (optional)

If you decide to change the filter:

  1. Unscrew the pan bolts (14 pieces, 10 mm wrench). Start at the corners to avoid distorting the pallet.
  2. Carefully remove the pan - ~0.5 liters of oil will remain in it.
  3. Replace the filter (part no. 31728-3MX0A) and pan gasket. The old gasket cannot be reused!
  4. Clean the pan of deposits (use carburetor cleaner or kerosene).

3. Filling with new oil

Oil must be filled through dipstick hole (located under the hood, next to the battery). Algorithm:

  1. Insert a funnel with a hose into the dipstick hole.
  2. Fill the oil in small portions (0.5 l each), checking the level with a dipstick.
  3. After filling 3–3.5 liters, start the engine and warm up the automatic transmission (switch the selector through all modes with a delay of 5 seconds).
  4. Add oil to the level between the marks HOT on the dipstick.

Critical do not overfill the oil! Excess leads to foaming, which can lead to loss of pressure and breakage of the box. The optimal level is 5 mm below the top mark HOT.

💡

After changing the oil, avoid sudden acceleration and towing for the first 100–200 km - the new oil should be evenly distributed throughout all automatic transmission components.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when changing automatic transmission oil. Here are the most dangerous of them:

  • 🔥 Cold replacement — the oil is not drained completely, and the new one is mixed with the old one, reducing the service life of the box.
  • 🛢️ Using the wrong oil - for example, Dexron III instead of JWS 3309. This leads to slipping of the clutches.
  • 🔧 Retightening the drain plug or pan bolts - may cause deformation of the thread or pan.
  • 📉 Incorrect oil level - both deficiency and excess are equally harmful.
  • 🧹 Ignoring tray cleaning — remaining chips and dirt will quickly contaminate the new oil.

Another common mistake is oil change without filter change on runs over 100 thousand km. The old filter no longer retains small particles, and they circulate throughout the system, accelerating wear.

What happens if you pour oil into an automatic transmission?

Overflowing oil into automatic transmission Almera G15 leads to foaming due to rotating parts (torque converter, gears). Foamed oil loses its lubricating properties and does not create the required pressure in the valve body. Consequences:

- Jerks and kicks when changing gears.

- Overheating of the box (foamed oil dissipates heat worse).

- Accelerated wear of clutches and solenoids.

- In critical cases - failure of the torque converter (repair cost from 30 thousand rubles).

Is it worth doing a partial replacement yourself?

Do-it-yourself automatic transmission oil change Almera G15 allows you to save 3–5 thousand rubles (that’s what the service charges for the work). However, there are nuances:

Advantages of self-replacement Cons
✅ Savings on work (1.5–2 thousand rubles for partial replacement). ❌ Risk of errors (underfilling, overfilling, incorrect filter).
✅ Quality control of oil and consumables. ❌ There is no guarantee - if something goes wrong, automatic transmission repair will be expensive.
✅ Possibility to inspect the pallet and magnet for the presence of shavings. ❌ Tools (keys, funnel, container) and time are required.

If you have never serviced an automatic transmission, it is better to contact a service center. Experienced Master:

  • 🔧 Check the condition of the oil and filter.
  • 🔍 Diagnoses the box for hidden problems (for example, wear of solenoids).
  • 📝 Will provide a guarantee for work (in most services - 1-3 months).

If you decide to do it yourself, follow the instructions strictly step by step and do not skimp on oil. Cheap, low quality oil can “kill” an automatic transmission Almera G15 for 10–20 thousand km.

FAQ: Frequently asked questions about changing the oil in an Almera G15 automatic transmission

Is it possible to fill in oil of a different viscosity if the original one is not available?

No! The oil must strictly comply with the specification JWS 3309. Using oils with a different viscosity (for example, Dexron VI or ATF+4) will lead to incorrect operation of the valve body and accelerated wear of the clutches. As a last resort you can use Idemitsu Type-J or Ravenol JWS 3309 - they are fully compatible with Nissan Matic S.

How many times do you need to do a partial change to refresh all the oil?

To completely update the oil, 2-3 partial changes will be required at intervals of 500-1000 km. With each replacement, ~40% of the volume is renewed. An alternative is a complete replacement using a high-pressure apparatus (done at a service center), but it is more expensive and requires 10–12 liters of oil.

What should you do if, after changing the oil, the automatic transmission begins to twitch?

Possible reasons:

  1. Incorrect oil level (check with a dipstick on a warm box).
  2. Poor quality or incompatible oil (drain and refill original).
  3. Clogged filter or solenoids (diagnostics required).
  4. Adaptation of the box (sometimes after changing the oil, the automatic transmission needs to be “trained” - reset the adaptations through a diagnostic scanner).

If the jerking does not go away after checking the level, contact the service for computer diagnostics.

Is it necessary to flush the automatic transmission during partial replacement?

Washing with special compounds (for example, Liqui Moly ATF Reiniger) is recommended only if the oil is heavily contaminated (black color, burning smell). In other cases, 2–3 partial replacements with an interval of 500–1000 km are sufficient. Flushing with aggressive agents can wash away useful deposits and disrupt the operation of the solenoids.

Is it possible to drive on old oil if there is no money for replacement?

If the oil is not black and does not smell like burning, you can postpone the replacement for 10–15 thousand km, but:

  • 🚗 Avoid sudden acceleration and towing.
  • 📅 Check the oil level every 5 thousand km.
  • 🔧 At the first signs of malfunction (jerking, noise), change the oil immediately.

Remember: automatic transmission repair will cost 5–10 times more than an oil change!
