Changing the oil in an automatic transmission Nissan Almera G15: a complete guide with nuances

Automatic transmission Nissan Almera G15 (model RE0F10A) requires regular maintenance to avoid costly repairs. Many owners mistakenly believe that the automatic transmission oil does not need to be changed - this is a myth that reduces the service life of the transmission by 30-40%. In this article we will look at how to change oil yourself automatic in box Almera G15, which oil to choose, what tools you will need and what to pay attention to so as not to damage the transmission.

Procedure for changing automatic transmission oil Nissan Almera G15 (2012–2018) has its own characteristics: there is no traditional dipstick for checking the level, and partial replacement does not completely update the fluid. We'll tell you how to do it complete replacement with flushing (by displacement method) and partial (40-50% oil renewal), and we will also explain why use of non-original oil NS-2 or NS-3 can lead to kicks and jerks of the box after 10–15 thousand km.

When to change the oil in a Nissan Almera G15 automatic transmission: regulations and signs of wear

Official regulations Nissan for Almera G15 says that the oil is in the automatic transmission does not require replacement - This is a marketing ploy aimed at reducing maintenance costs. In practice, the liquid loses its properties after 60–80 thousand km, and under difficult operating conditions (city traffic jams, towing, aggressive driving) - even earlier.

Signs that there is oil in the automatic transmission Almera G15 it's time to change:

• 🔴 Jerks or kicks when changing gears (especially from 1st to 2nd).
• 🔴 Delays when switching (the box “thinks” for 1–2 seconds).
• 🔴 Vibration or a hum from the automatic transmission in neutral or when driving.
• 🔴 Darkening of the oil (when checking through the drain plug).
• 🔴 Burning smell from transmission fluid.

If you ignore these symptoms, the wear of clutches and solenoids will accelerate, which will lead to hydraulic unit failure or wear of the planetary mechanism. Average cost of automatic transmission repair Almera G15 - from 80 to 150 thousand rubles, while an oil change will cost 3–5 thousand rubles.

⚠️ Attention: If there is oil in the automatic transmission Almera G15 metal particles or shavings are detected, the box already requires diagnostics. Changing the oil in this case will only temporarily delay the repair.

What kind of oil to fill in the automatic transmission of Nissan Almera G15: original vs analogues

Automatic transmission RE0F10A in Nissan Almera G15 demanding on oil quality. Officially Nissan recommends using ATF NS-2 (article KE908-99931) or NS-3 (article KE909-99945). However, there are nuances:

• 🔧 NS-2 - suitable for boxes up to 2015, but may cause slippage at low temperatures.
• 🔧 NS-3 - a more modern formula, better protects against wear, but costs 20-30% more.
• 🔧 Analogues: Idemitsu ATF Type-J, Ravenol ATF NS-2/NS-3, Mobil ATF 3309 - tested by owners, but require confirmation of compatibility.

Automatic transmission oil volume Almera G15:

Replacement type	Volume, l	Notes
Partial replacement	3.5–4.0	~40% of liquid is renewed
Complete replacement (displacement method)	7.5–8.0	Requires a washing machine
First replacement (after 100+ thousand km)	5.0–6.0	2–3 partial replacements are recommended at 500 km intervals

Do not use oils labeled Dexron III or ATF+4 - they are incompatible with solenoids RE0F10A and may cause valve jamming valve body

⚠️ Attention: When mixing NS-2 And NS-3 foam may form, which will lead to a drop in pressure in the automatic transmission and emergency mode.

Tools and consumables for changing the oil in the Almera G15 automatic transmission

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

The process of changing the oil in an automatic transmission Nissan Almera G15 consists of several stages. Let's consider partial replacement (without removing the pan) and full (with removing the pan and replacing the filter).

Partial oil change (40–50% update)

1. Warm up the oil: Start the engine, let it run for 5-10 minutes, then drive 5-10 km. This is necessary so that the oil becomes less viscous and drains better.
2. Drain the old oil:
   • Raise the car on a lift or ramp.
   • Unscrew the drain plug (10 mm wrench) - oil will begin to flow out.
   • Place the container and wait until it drains completely (about 3.5–4 l).
3. Filling with new oil:
   • Screw on the drain plug with a new washer (part no. 11026-01M02).
   • Remove the filler plug (located next to the drain, under the plastic protection).
   • Fill in new oil with a syringe or through a funnel. The volume is equal to the drained volume.

Complete oil change (with pan removal and washing)

1. Remove the automatic transmission pan:
   • Unscrew all pan bolts (10mm socket).
   • Carefully remove the pan - ~0.5 liters of oil will remain in it.
   • Clean the tray and magnets from metal shavings.
2. Replace the filter:
   • The filter is secured with 3 bolts (10 mm wrench).
   • Install a new filter and a new pan gasket.
3. Displacement flushing (optional):
   • Connect the flushing device to the automatic transmission radiator pipes.
   • Start the engine and bleed the system until clean oil comes out.

After replacement be sure to check the oil level:

1. Warm up the box to 60–70°C (drive 10–15 km).
2. Place the machine on a level surface.
3. Unscrew the control plug (on the side wall of the automatic transmission). If oil drips, the level is normal. If not, add more.

Common mistakes when changing oil in an Almera G15 automatic transmission

Even experienced car owners make mistakes that can damage the automatic transmission. Here are the most critical ones:

• ❌ Overfilling or underfilling oil - leads to foaming or oil starvation. The optimal level is when oil begins to drip from the inspection hole at operating temperature.
• ❌ Using non-original gaskets - cheap analogues tan and leak oil after 10-15 thousand km.
• ❌ Automatic transmission flushing with solvents — aggressive compounds destroy oil seals and clutches.
• ❌ Changing the oil without changing the filter - the old filter becomes clogged with wear products, and the new oil quickly becomes contaminated.
• ❌ Ignoring metal shavings — if there are a lot of chips on the pan magnets, the box is already worn out, and changing the oil will only temporarily delay the repair.

Another common mistake is Changing the oil after the car has been idle for a long time. If Almera G15 has not been used for more than 2–3 months, the oil in the automatic transmission is stratified, and with a sudden start it is possible water hammer in the torque converter.

⚠️ Attention: If after changing the oil there are jerks when switchingMost likely, incompatible oil was filled in or the automatic transmission adaptations were not reset. In this case it is required error reset via a diagnostic scanner (for example, Launch X431).

Resetting automatic transmission adaptations after changing the oil

After changing the automatic transmission oil Nissan Almera G15 it is necessary to reset the adaptation (learning) box. This is due to the fact that the old oil had a different viscosity, and the electronic control unit (ECU) adjusted to it. If you do not reset, the following are possible:

• 🔴 Delays when switching.
• 🔴 Hard kicks.
• 🔴 Incorrect determination of the switching moment.

There are two ways to reset adaptations:

1. Via diagnostic scanner:
   • Connect the scanner (for example, Launch CReader or Delphi DS150E).
   • Select menu AT → Adaptations Reset.
   • Confirm the reset and reset the ECU (disconnect the battery for 10 minutes).
2. Manual reset (less efficient, but works):
   • Remove the battery terminal for 15–20 minutes.
   • Press the brake pedal and hold for 30 seconds (discharges the ECU capacitors).
   • Connect the battery and start the car. Let it idle for 5-10 minutes, then drive 10-15 km in gentle mode.

After resetting the adaptations, the box may work unstable for the first 50–100 km - this is normal. The ECU “learns” again to shift gears for the new oil.

The cost of changing the oil in an Almera G15 automatic transmission in a service vs on your own

Prices for changing automatic transmission oil Nissan Almera G15 vary depending on region and type of service:

Replacement type	Cost of service, rub.	Cost on your own, rub.
Partial replacement (without filter)	2 500–3 500	1 500–2 000
Complete replacement (with filter and flushing)	5 000–7 000	3 000–4 000
Diagnostics + reset adaptations	1 500–2 500	Free (if you have a scanner)

Self-replacement is 30–50% more profitable, but requires time and accuracy. If you have never worked with an automatic transmission, it is better to contact a service center - mistakes when changing the oil can cost many times more.
