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

Automatic transmission Nissan Almera G15 (RE0F10A) requires regular maintenance, but many owners neglect changing the oil, considering the procedure unnecessary. This is a dangerous misconception: contaminated ATF fluid leads to clutch slipping, torque converter overheating and premature wear of solenoids. In this article we will look at how to change the oil in an automatic transmission yourself. Almera G15 taking into account all technical nuances - from choosing the original fluid to checking the level after replacement.

Official regulations Nissan prescribes the first automatic transmission oil change on the run 90–100 thousand km, but in Russian conditions (frequent traffic jams, low temperatures, aggressive driving style) the interval should be reduced to 60–70 thousand km. Moreover, we are not talking about partial, but about complete replacement using the double pass method — this is the only way to remove up to 90% of the old fluid from the torque converter and valve body channels. If you have never changed the oil in your automatic transmission Almera G15, prepare for unpleasant surprises: most likely, you will need to wash the pan and replace the filter.

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

The manufacturer recommends using exclusively Nissan Matic Fluid S (article KE908-99932) is a semi-synthetic fluid with a unique package of additives adapted to the box RE0F10A. However, there are worthy analogues on the market that meet the specifications JWS 3309:

• 🔹 Idemitsu ATF Type-M - a complete analogue of the original, often used in services
• 🔹 Ravenol ATF J1D1707 - synthetics with improved antioxidant properties
• 🔹 Motul Multi ATF - universal fluid, suitable for partial replacement
• 🔹 Liqui Moly Top Tec ATF 1200 - premium option for harsh operating conditions

Important: do not use fluids labeled Dexron III/VI or Mercon - they are incompatible with clutches Almera G15 and can cause jerking when switching. Also avoid universal ATF fluids from little-known brands: saving 500–1000 rubles will result in a box repair costing 50–80 thousand rubles.

⚠️ Attention: If your automatic transmission is already filled with a different type of oil (for example, the previous owner used Toyota T-IV), complete replacement using the pass method is prohibited - mixing liquids will lead to the formation of sediment. In this case, it is necessary to dismantle the box and wash all components.

Tools and consumables: a complete checklist for replacement

To change the automatic transmission oil yourself Nissan Almera G15 you will need:

10 mm socket wrench (for drain plug)

14 mm socket (for pallet)

5 mm hexagon (for level)

Funnel with extension (diameter 8–10 mm)

Container for draining (volume no less than 6 l)

New automatic transmission filter (article 31726-31X00)

Pan gasket (article 31397-31X02)

Original Nissan Matic S oil (8–9 liters)

Carburetor cleaner (for flushing the pan)

Lint-free rags and gloves -->

Pay special attention to the filter: Almera G15 There are two types used - metal mesh (article 31726-31X00) and paper (article 31728-31X00). The first can be washed and installed back, the second must be replaced. If you are planning a complete replacement using the run-through method, prepare additional 4–5 liters of oil — they will be needed to flush the system.

Also don't forget about the little things: pan sealant (For example, Loctite 574), torque wrench (tightening torque of the pallet bolts - 8–10 Nm) and oil syringe through the dipstick. If you don't have a pit or lift, use jack with stops - but work extremely carefully, as the box weighs about 50 kg.

Step-by-step instructions: partial oil change in automatic transmission

Partial replacement is suitable for routine maintenance and allows for upgrades 30–40% liquid. The procedure takes 1–1.5 hours and does not require special skills.

1. Draining old oil:

   Place the car on a level surface and turn off the engine. Place a container under the drain plug (it is located on the automatic transmission pan on the right). Unscrew the plug with a 10 mm wrench and wait until it drains completely. On average it flows 3.5–4 liters liquids.

2. Removing the pallet:

   Unscrew the 18 pan bolts with a 14 mm socket (start from the corners so as not to deform the surface). Carefully remove the pan - there will still be ~0.5 liters of oil left in it. Clean the magnets from metal shavings and wash the pan with carburetor cleaner.

3. Filter replacement:

   B Almera G15 The filter is secured with 3 bolts. Remove it, remove the remains of the old gasket and install a new one. If the filter is metal, wash it in gasoline and blow with compressed air.

4. Installing the pan and filling the oil:

   Apply a thin layer of sealant to the pan gasket, install it in place and tighten the bolts evenly. Through the filler hole (next to the dipstick) add 3.8–4 liters of new oil using a funnel.

5. Level check:

   Start the engine, warm up the gearbox to 60°C (control OBD-II or diagnostic scanner). Switch the selector through all modes, then set it to position P. Remove the dipstick, wipe it and check the level - it should be between the marks HOT.

⚠️ Attention: If after changing the oil quickly darkens (within 500–1000 km), this is a signal about severe wear of clutches. In this case, diagnostics of the box is required - the solenoids or valve body may need to be replaced.

What to do if there is no dipstick?

In some modifications of the Almera G15, there is no dipstick - instead, a control plug on the pallet is used. To check the level:

1. Warm up the box to 60°C.

2. Stop the engine and unscrew the plug (5 mm hexagon).

3. If the oil drips in a thin stream, the level is normal. If it doesn’t flow, add 100–200 ml through the filler hole.

4. Tighten the plug to a torque of 35 Nm.

Complete oil change using double run method

This method allows you to update 85–90% liquid in the system, including oil in the torque converter and valve body. Will be required 8–9 liters ATF and an assistant to control the process.

Algorithm of actions:

1. First flush: Perform a partial change as described above, but do not check the level after adding new oil.
2. Oil run: connect the hose to the automatic transmission radiator return fitting (it is located to the right of the box) and direct it into a container. Start the engine and old oil will flow through the hose. As soon as the color of the liquid becomes light, turn off the engine.
3. Second drain: drain the oil from the pan, wash it and replace the filter. Refill with fresh ATF and repeat the run.
4. Quality control: After the second run, check the oil level and color. If it is pinkish, the procedure was successful. If it remains brown, a third pass will be required.

Critical: do not allow the gearbox to operate without oil longer than 30 seconds will damage the torque converter pump wheel. Also monitor the temperature: if the automatic transmission overheats above 90°C, take a break for 10–15 minutes.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when changing automatic transmission oil. Almera G15. Here are the most common:

• 🚫 Overfilling or underfilling oil: both options are dangerous. Overfilling leads to foaming of the liquid and loss of pressure, while underfilling leads to oil starvation. Always check the level on a warm box!
• 🚫 Using a non-original pan gasket: Cheap analogues become tanned in the cold and begin to leak oil. Take only Nissan 31397-31X02 or Fel-Pro.
• 🚫 Ignoring magnets in the tray: If you do not clear the magnets of chips, they will fall back into the box and accelerate the wear of the vane pumps.
• 🚫 Changing the oil without flushing the pan: up to 0.5 liters of old ATF with abrasive particles accumulates in the pan. Wash it with carburetor cleaner or kerosene.
• 🚫 Application of flushing additives: They dilute the remaining old oil, but do not remove it completely. It's better to do a double run.

Another common mistake is improper tightening of pan bolts. If you overtighten, you can deform the surface and break the thread. If you don't tighten it enough, the pan will leak. Use a torque wrench and keep the torque 8–10 Nm.

Also many people forget reset automatic transmission adaptations after changing the oil. This leads to jerking when switching, as the electronic control unit continues to work according to the old algorithms. The reset is done via a diagnostic scanner (for example, Launch X431) or by disconnecting the battery terminal for 10 minutes.

Signs that it’s time to change the automatic transmission oil

If you are not sure whether the gearbox oil needs to be changed Almera G15, pay attention to the following symptoms:

• ⚠️ Jerks when switching (especially from 1st to 2nd gear) - low pressure signal due to contaminated ATF.
• ⚠️ Burning smell from under the hood - the oil has overheated and lost its properties.
• ⚠️ Dark liquid color on the dipstick (should be reddish, not black or brown).
• ⚠️ Hum or vibration in neutral gear - wear of the torque converter bearings is possible.
• ⚠️ Oil leaks under the box - check the oil seals and pan gasket.

If you notice any of these signs, don't put off changing the oil. In advanced cases, repair of solenoids (from 15 thousand rubles) or replacement of the valve body (from 40 thousand rubles) will be required. To check the condition of the oil you can use test strips (For example, ATF Check Dipstick), which indicate the level of oxidation and the presence of wear products.

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

The cost of replacement depends on the type of procedure and region. In Moscow and St. Petersburg, prices are 20–30% higher than in the regions.

Replacement type	Cost of work, ₽	Cost of consumables, ₽	Total, ₽
Partial replacement	1500–2500	3000–4500	4500–7000
Complete replacement (run)	3000–5000	6000–8000	9000–13000
Replacement with flushing of the valve body	5000–7000	8000–10000	13000–17000

There is no need to skimp on the quality of oil: the difference between the original Nissan Matic S (about 1000 ₽/l) and analogues (Idemitsu or Ravenol 800–900 ₽/l) is insignificant, but the consequences of using low-quality ATF will cost many times more. Also pay attention to promotions in services: sometimes a complete replacement with automatic transmission diagnostics is cheaper than a partial one.

If you decide to change the oil yourself, the costs are reduced to the cost of consumables. However, keep in mind that without a pit or lift, the procedure will take 2-3 times longer, and the risk of errors will increase.

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

Is it possible to mix different ATF fluids in an Almera G15 automatic transmission?

Mix strictly prohibited, even if the fluids are within specification JWS 3309. Different manufacturers use incompatible additive packages, which can react and form sludge. If you don't know what kind of oil is in the box, do complete replacement using the run method.

How often do you need to change the automatic transmission oil if the car is used in a taxi?

For commercial use (taxi, car sharing), the replacement interval is reduced to 40–50 thousand km. It is also recommended to check the oil level and condition every 20 thousand km. In a taxi, the gearbox operates under increased loads, so the risk of overheating and wear of the clutches is higher.

What happens if you don’t change the oil in the Almera G15 automatic transmission?

The consequences depend on the mileage:

• 100–150 thousand km: jerks when switching, increased fuel consumption.
• 150–200 thousand km: clutch slipping, solenoid errors (P0730, P0740).
• 200+ thousand km: destruction of torque converter bearings, jamming of vane pumps.

In the worst case it will be necessary automatic transmission overhaul (from 60 thousand rubles) or replacement of the box (from 150 thousand rubles).

Is it necessary to flush the automatic transmission radiator when changing the oil?

Radiator flushing is required if:

• The oil has a burning smell or is dark in color.
• A large amount of metal shavings was found in the pan.
• The box overheated (for example, when towing a trailer).

For rinsing use special cleaner (For example, Wynns TransCleaner) or run 1–2 liters of fresh ATF through the radiator.

Is it possible to drive with a slightly lower automatic transmission oil level?

Short-term driving (up to 500 km) with a level 10–15% below normal is acceptable, but long-term use will lead to:

• Accelerated wear of clutches and solenoids.
• Overheating of the torque converter (risk of blade deformation).
• Loss of pressure in the valve body (jerking when switching).

If the level has dropped due to a leak, eliminate the cause immediately (most often the drive shaft oil seal or pan gasket is to blame).
