Nissan Almera G15 with automatic transmission RE0F10A (Jatco JF015E) requires timely replacement of the transmission fluid - this is critical for the durability of the unit. Many owners mistakenly believe that automatic transmission oil is “eternal”, but the manufacturer recommends updating it every 60–90 thousand km (or once every 4–5 years) depending on operating conditions. In Russian realities with frequent traffic jams, low temperatures and dust, it is better to reduce the interval to 40–50 thousand km.

This article contains detailed instructions for changing the oil in an automatic transmission. Almera G15 (2012–2019), including the choice of fluid, the necessary tools, the step-by-step process (partial and complete replacement), as well as common mistakes that lead to box failures. We will analyze the nuances for different years of production, tell you how to check the oil level without a dipstick, and give recommendations for break-in after replacement.

What kind of oil to fill in the automatic transmission of Nissan Almera G15

Box RE0F10A in Almera G15 extremely sensitive to the type of transmission fluid. The manufacturer indicates the original liquid Nissan Matic Fluid S (article KLE52-00004), but there are also high-quality analogues. Important: Oil must meet specification JWS 3309 or Nissan Matic S.

Suitable options:

  • 🔹 Original: Nissan Matic S (1 l - ~1,200 ₽). The best choice, but often counterfeited. Check the packaging for the hologram and serial number.
  • 🔹 Analogues:
    • Idemitsu ATF Type-J (article 30050013-771) - recommended by many services.
    • Ravenol ATF J1 (article 4014835755406) - German quality, suitable for cold climates.
    • Mobil ATF 3309 - a budget option, but requires more frequent replacement.
  • 🔹 What to Avoid: liquids with markings Dexron III/VI, ATF+4 or universal “for all automatic transmissions”. They are not compatible with clutches Jatco JF015E and lead to gear slippage.

Oil volume to change:

Replacement type Volume, l Notes
Partial (drain through plug) 3.5–4.0 ~40–50% of the fluid is replaced. Recommended for regular maintenance.
Full (hardware or manual) 7.0–7.5 Requires flushing the valve body and replacing the filter. This is done once every 100–120 thousand km.
Topping up 0.2–0.5 Only original oil! Mixing different brands is prohibited.
⚠️ Attention: In automatic transmission Almera G15 there is no traditional dipstick to check the oil level. The level is checked through the control hole on the pallet at the operating temperature of the box (50–60°C). Using the wrong fluid or overfilling/underfilling will lead to jerking when shifting gears and accelerated wear of the solenoids.

Tools and consumables for replacement

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

  • 🔧 Tools:
    • Allen key 10 mm (for drain plug).
    • Socket head 14 mm (for pallet bolts if a complete replacement is planned).
    • Torque wrench (plug tightening torque - 35 Nm, pallet - 10 Nm).
    • Funnel with extension (diameter of the filler neck - ~16 mm).
    • Oil syringe (if adding through the breather).
  • 🛢️ Consumables:
    • Automatic transmission oil (see section above).
    • Pan gasket (item no. 31397-31X02) or sealant Loctite 574 (if the tray is not removable).
    • Automatic transmission filter (part number 31726-31X01) - only for complete replacement.
    • O-ring for drain plug (part no. 11026-01M02).
    • Lint-free rags, gloves, drainage container (minimum 5 l).

To check the oil level you will need a diagnostic scanner (for example, Launch X431 or ELM327) to read the automatic transmission temperature. Without it, you can’t rely on it “by eye” - there is a risk of underfilling or overfilling.

📊 How often do you change the automatic transmission oil?
  • Every 40–50 thousand km
  • Every 60–80 thousand km
  • Only when problems arise
  • Never changed
  • I don't know

Step-by-step instructions: partial oil change

Partial replacement is suitable for regular maintenance and takes ~1.5–2 hours. It does not require removing the pan and replacing the filter, but it only renews ~40% of the fluid.

Step 1. Preparation

  • 🅿️ Drive the car onto a pit or lift. The box must be cold (oil temperature not higher than 30°C).
  • 🔧 Remove the crankcase protection (if equipped). B Almera G15 it is secured with 4 bolts 10 mm.
  • 🧹 Clean the area around the drain plug from dirt (use a wire brush and cleaner WD-40).

Step 2: Drain the oil

  • 🛢️ Place a container under the drain hole (volume of at least 4 l).
  • 🔧 Carefully unscrew the drain plug with a key 10 mm. The oil will start leaking out immediately - be careful!
  • ⏳ Wait for complete drainage (10-15 minutes). In cold weather, the oil thickens - you can slightly warm the box to 20-25°C to speed up the process.

Step 3. Filling with new oil

  • 🔧 Tighten the drain plug with a new sealing ring (tightening torque - 35 Nm).
  • 🛢️ Fill in new oil through the filler hole (located on top of the box, next to the battery). Use a funnel with an extension.
  • 📏 Volume for filling: 3.5–4.0 l (until it starts to drip from the control hole).

Drain old oil (volume ~3.5 l)|

Tighten the plug with a new ring (torque 35 Nm)|

Pour new oil through the top hole|

Warm up the box to 50–60°C and check the level|

Dispose of waste at a special point -->

Step 4. Check the level

  • 🔥 Start the engine and warm up the box to operating temperature (50–60°C). To do this, drive 5–10 km or let it idle for 15–20 minutes.
  • 📊 Connect the scanner and check the oil temperature in the automatic transmission (parameter ATF Temp). It must be in the range 50–60°C.
  • 🔧 With the engine running, unscrew the control plug (aka filler plug). If the oil drips in a thin stream, the level is normal. If not, add more.
⚠️ Attention: If after the replacement there are jerks when switching from 1st to 2nd gear, it means that the oil is overfilled or underfilled. This may also indicate contamination of the solenoids - in this case, a complete replacement with washing will be required.

Complete automatic transmission oil change: when is it needed and how to do it

Complete automatic transmission oil change Nissan Almera G15 recommended in cases:

  • 🔄 Mileage more 100 thousand km without replacement.
  • 🚨 The appearance of jerks and delays when changing gears.
  • 🔥 The oil in the pan has a dark color, a burning smell or metal shavings.
  • 🛠️ After repairing the box (replacing clutches, solenoids).

For a complete replacement you will need:

  1. Drain the old oil through the plug (as in a partial replacement).
  2. Remove the automatic transmission pan, clean it and the magnets from chips.
  3. Replace the coarse filter (part no. 31726-31X01).
  4. Install the pan with a new gasket (bolt tightening torque - 10 Nm).
  5. Fill in new oil and “drive” it through the box:
    • Connect the hoses to the automatic transmission cooling radiator.
    • Start the engine and drain the oil until clear fluid comes out.
  • Add oil to the level and check the operation of the box.

    • Oil volume for a complete change: 7.0–7.5 l. The process takes 3-4 hours and requires skills - if you are not sure, it is better to contact the service.

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

    If you ignore changing the oil in the automatic transmission Nissan Almera G15 after 100–120 thousand km the following problems arise:

    1. Friction wear — gear slipping, slipping.
    2. Solenoid contamination — jerks when switching, error P0730.
    3. Oil overheating — loss of properties, formation of varnish deposits.
    4. Valve block failure — repairs will cost 50–80 thousand rubles.

    In critical cases, the box goes into emergency mode (Check AT on the dashboard) and requires major repairs.

    Common mistakes when changing oil and how to avoid them

    Even experienced car owners make mistakes that lead to automatic transmission breakdowns. Here are the most common:

    • 🚫 Using the wrong oil. For example, fill Dexron III instead of Nissan Matic S leads to the destruction of friction clutches within 10–15 thousand km.
    • 🚫 Incorrect oil level:
      • Underfilling - the pump will capture air, which will cause kicks when switching.
      • Overflow - Excessive pressure will damage the seals and seals.
    • 🚫 Replacement without warming up the box. Cold oil does not drain completely, and new oil does not mix well with old.
    • 🚫 Ignore filter. When completely replacing, be sure to change the filter - a clogged filter leads to oil starvation.
    • 🚫 Mixing different oils. Even if both meet specification JWS 3309, mixing Nissan Matic S And Idemitsu Type-J may cause a chemical reaction.

    How to avoid problems:

    • ✅ Always check the oil temperature with a scanner.
    • ✅ Use only original consumables (gaskets, filter, plugs).
    • ✅ After replacement, drive 50–100 km and recheck the level.
    💡

    If, after changing the oil, the automatic transmission begins to “kick” when cold, warm up the box to operating temperature (drive 10–15 km). In 80% of cases, jerking disappears after the solenoids adapt to the new fluid.

    How to check the oil level without a dipstick

    In automatic transmission Nissan Almera G15 there is no dipstick - the level is checked through the inspection hole. Algorithm:

    1. 🅿️ Place the car on a flat surface.
    2. 🔥 Warm up the box until 50–60°C (use a scanner or estimate a 10-15 minute drive).
    3. 🔧 With the engine running, switch the selector through all positions (P → R → N → D → L) with a delay of 3–5 seconds.
    4. 🔧 Unscrew the control plug (aka filler plug) on the box. If oil:
      • 💧 Dripping in a thin stream - the level is normal.
      • 💧 Doesn't drip — add 100–200 ml and repeat the check.
      • 💧 It pours abundantly - overflow, drain off excess.
  • 🔧 Tighten the plug (moment 35 Nm).

    • If there is no scanner, focus on the engine temperature: when 80–90°C coolant, the oil temperature in the automatic transmission will be ~50–60°C.

    What to do after changing the oil: break-in and adaptation

    After changing the automatic transmission oil Nissan Almera G15 requires adaptation:

    • 🚗 Drive 50–100 km in a gentle mode (without sudden starts and braking).
    • 🔄 For the first 2–3 days, avoid towing and driving at high speeds (more than 3,500 rpm).
    • 📊 If the box is “stupid” when switching, reset the adaptations through the scanner (procedure AT Reset).

    Typical symptoms after replacement and their causes:

    Symptom Possible reason Solution
    Jerks when shifting 1st–2nd gears Incorrect oil level or air lock Check the level, top up if necessary
    Power-on delay D or R Low oil temperature or dirty solenoids Warm up the box, if that doesn’t help, wash the valve body
    Noise or vibration at speed Poor quality oil or bearing wear Replace the oil with the original one, check the pan for chips
    💡

    If after changing the oil the automatic transmission is unstable, do not panic - in 90% of cases this is a temporary phenomenon associated with the adaptation of the solenoids to the new fluid. Give the box 100–200 km to break in.
