Automatic transmission oil Nissan Almera G15: a complete guide to selection and replacement

Nissan Almera G15 with automatic transmission - a popular choice among owners due to reliability and efficiency. However, even the most durable automatic transmission requires regular maintenance, and the key point here is oil. Not only the smoothness of switching, but also the life of the entire transmission depends on its quality and timely replacement.

Many drivers mistakenly believe that the oil in the automatic transmission Almera G15 Filled "for the entire service life". This is a myth: the manufacturer recommends checking its condition every 60,000 km, and replacement should be carried out at least after 90,000–120,000 km (depending on operating conditions). In this article we will look at which oil is suitable for Jatco JF015E (installed on Almera G15), how to replace it correctly and what mistakes can lead to expensive repairs.

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

From factory to automatic transmission Nissan Almera G15 (2013–2019) original oil is filled Nissan Matic Fluid S (article KE908-99931). This fluid is designed specifically for transmissions. Jatco and complies with the standard JWS 3309. Important: not to be confused with Matic D or J - they are incompatible with JF015E and can cause malfunctions in the valve body.

The original oil has the following characteristics:

• 🔴 Color: red (when new), darkens to brown over time.
• 🌡️ Temperature range: -40°C to +150°C (stable viscosity under extreme loads).
• 🛢️ Viscosity: Complies with SAE 75W-80, but with unique additives for Jatco.

Critical feature: Nissan Matic S contains special detergent additives that prevent the formation of varnish deposits on the valve body solenoids. Replacing with universal ATF (for example, Dexron VI) will lead to clogged channels and jerks when switching.

Analogues of the original oil: what can you fill in?

Original oil Nissan Matic S is expensive (from 1,200 rubles/liter), so many owners are looking for high-quality analogues. The main rule: the liquid must meet the specification JWS 3309 or Nissan Matic S. Here are the tested options:

Brand	Title	Article	Price (liter), rub.	Notes
Idemitsu	ATF Type TL	30450-54055	900–1 100	Complete analogue of Matic S, used on the Nissan assembly line
Ravenol	ATF J1 Fluid	4014835734517	850–1 000	Contains enhanced anti-wear additives
Mobil	ATF 3309	153632	750–900	Suitable for harsh environments
ZIC	ATF SP-IV	162627	600–750	Budget option, but requires more frequent replacement

⚠️ Attention: Do not use oils labeled Dexron III/VI or Mercon V - they are incompatible with clutches JF015E and will lead to gear slippage. Also avoid universal “ATF for all automatic transmissions” - they do not take into account the features of solenoids Jatco.

Oil volume in Almera G15 automatic transmission: how much to fill?

Total oil volume in box JF015E amounts to 7.2 liters, but when replacing you will not need all this volume. The quantity depends on the method:

• 🔄 Partial replacement (drain through the plug): 3.5–4 liters.
• 🔃 Complete replacement (hardware or manual flushing): 7–7.5 liters.
• 🛠️ Replacement with removal of the pallet: 4.5–5 liters (including filter).

During a partial replacement, the old oil is mixed with the new one, so it is recommended to repeat the procedure every 30,000 km (2-3 times to completely refresh the fluid). A complete replacement is required when:

• 🔥 Darkening the oil to black.
• 🚨 The appearance of metal shavings on the tray magnets.
• ⚠️ Jerks or delays when changing gears.

When to change the oil in an Almera G15 automatic transmission: signs of wear

The manufacturer specifies the replacement interval in 90,000 km, but in Russian conditions (traffic jams, low temperatures, aggressive driving) this period is reduced to 60,000–70,000 km. The following symptoms indicate the need for replacement:

• 🔴 Oil color change: from red to brown or black (checked with a probe).
• 💨 Burning smell - a sign of overheating of the clutches.
• ⚡ Jerks when switching (especially when cold).
• 🔊 Hum or vibration in the field of automatic transmission.
• 🛑 Delays when switching gears (more than 1–2 seconds).

Critical moment: if the oil has darkened and has a metallic sheen, this indicates the destruction of the friction discs. In this case, it is necessary not only to replace the fluid, but also to diagnose the box - it may be necessary to repair the valve body or replace the solenoids.

What happens if you don't change the oil?

If you ignore changing the oil in the Almera G15 automatic transmission after 150,000 km, the following problems arise:

- The valve body channels become clogged, which leads to insufficient pressure and slipping of the clutches.

- The wear of bearings and gears increases, which is manifested by a hum in neutral gear.

- Solenoids fail due to varnish deposits, causing erratic gear changes.

- In severe cases, a major overhaul of the box is required (from RUB 80,000).

Step-by-step instructions for changing the oil in an Almera G15 automatic transmission

The replacement can be carried out independently (if there is a hole or a lift) or at a service center. Let's consider partial replacement - the most accessible and safe method.

Required tools and materials:

Buy 4 liters of oil (Nissan Matic S or equivalent)

New automatic transmission filter (part number 31726-31X0A)

Pan gasket (item no. 31397-31X00)

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

Funnel with long spout

Rags and container for old oil (minimum 5 l)

Torque wrench (for tightening the plug with a torque of 35 Nm)-->

Step 1. Warm up the oil

Start the engine and let it run for 5–10 minutes so that the oil in the automatic transmission warms up to 50–60°C. This will reduce its viscosity and allow the maximum volume to be drained. Switch the selector through all positions (P-R-N-D) with a delay of 3 seconds.

Step 2. Drain the old oil

Place the machine on a pit or lift. Place a container under the drain plug (located on the automatic transmission pan). Unscrew the plug with a 24 mm wrench and wait until it drains completely (about 3.5 liters). Pay attention to the color and smell of the oil - if it is black with a burning smell, a complete replacement will be required.

Step 3: Replace the filter and gasket

Remove the automatic transmission pan (10 bolts around the perimeter). Carefully clean any metal shavings from the magnets. Replace the filter (even if it is visually clean - its resource is limited). Install a new pan gasket to prevent leaks.

Step 4. Filling with new oil

Tighten the drain plug (torque 35 Nm). Through the filler neck (located next to the dipstick), add new oil in a volume equal to the amount drained. Use a funnel to avoid spills. Start the engine and check the level on the dipstick - it should be between the marks MIN And MAX at operating temperature (60°C).

1. Stop the engine.

2. Disconnect the battery terminal for 10 minutes.

3. Plug it back in and start the car.

This will help the box “learn” the new properties of the oil.-->

Common mistakes when changing oil in an Almera G15 automatic transmission

Even experienced drivers make mistakes that can lead to gearbox failure. Here are the most critical ones:

⚠️ Attention: Never mix different types of oils (eg Matic S And Dexron VI)! This causes a chemical reaction, leading to the formation of sediment and clogging of the valve body channels. If you do not know what oil was previously filled, perform complete replacement.

• 🔧 Overfilling or underfilling oil. Excess leads to foaming and loss of properties, deficiency leads to oil starvation. Always check the level on a warm box!
• 🧲 Ignoring magnets. If you do not clean the chips from the pan magnets, they will continue to circulate in the oil, accelerating wear on the parts.
• 🔩 Incorrect tightening torque. The drain plug must be tightened firmly 35 Nm. Over-tightening will lead to thread breakage, and weak tightening will lead to leakage.
• 🚗 Replacement without adaptation. After changing the oil, the automatic transmission needs to be “trained” - otherwise jerks are possible for the first 100–200 km.

Another common mistake is using flushing liquids. They have an aggressive effect on the seals and can cause leaks. If flushing is required, use only specialized products for automatic transmissions (for example, Liqui Moly ATF Reiniger).

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

Is it possible to fill Dexron VI instead of Nissan Matic S?

No, absolutely not. Dexron VI has a different additive package and is not compatible with clutches JF015E. This will lead to gear slippage and premature wear of the valve body. Use only approved oils JWS 3309.

How to check the oil level in an Almera G15 automatic transmission?

The check is performed on a heated box (oil temperature 50–60°C):

1. Place the machine on a level surface.
2. Start the engine and move the selector through all positions (P-R-N-D).
3. Remove the dipstick, wipe it and insert it back.
4. Pull the dipstick out again - the level should be between MIN And MAX.

If the oil is below MIN, top up through the filler neck. If higher MAX - drain the excess through the stopper.

How much does it cost to change the oil in an Almera G15 automatic transmission?

The cost depends on the type of replacement:

• Partial replacement (3.5–4 liters of oil + filter): RUB 3,000–4,500.
• Complete replacement (hardware room, 7–8 liters of oil): 6,000–8,000 rubles.
• Replacement with flushing (with removal of the tray and cleaning of the magnets): 5,000–6,500 rubles.

The price does not include the cost of oil (from 800 rubles/liter for the original).

What to do if the automatic transmission jerks after changing the oil?

This is normal in the first 100–200 km - the box needs time to adapt to the new oil. If jerks do not pass:

• Check the oil level (possibly underfilled or overfilled).
• Reset adaptations by disconnecting the battery for 10 minutes.
• If the problem persists, contact service - the solenoids may need diagnostics.

Is it possible to drive with darkened automatic transmission oil?

If the oil has darkened, but does not smell of burning or metal shavings, you can drive another 5,000–10,000 km, but don't delay replacement. Dark color indicates the beginning of oxidation of additives, which impairs lubricating properties. If the oil is black with a burning smell, an urgent replacement and diagnosis of the box is required.
