Changing the oil in the <em>Nissan Juke</em> automatic transmission: instructions, choice of oil and nuances of the procedure

Automatic transmission Nissan Juke - a complex unit that requires regular maintenance. Many owners mistakenly believe that the automatic transmission oil does not need to be changed, but this is a myth: over time, the fluid loses its properties, becomes contaminated with wear products and ceases to protect parts from friction. If you ignore the replacement, the consequences can be critical - from jerks when switching to complete failure of the box.

In this article we will look at how to change the oil in an automatic transmission yourself. Juke (including models with CVT Jatco JF015E), which fluids are suitable, when to do it and what mistakes car owners most often make. The information is relevant for gasoline versions with engines HR15DE (1.5 l) and MR16DDT (1.6 l), as well as diesel K9K (1.5 dCi).

When to change automatic transmission oil Nissan Juke: official and real terms

The manufacturer indicates in the manual that the oil in the automatic transmission Juke filled for the entire service life. However, this is only true for “ideal” operating conditions - moderate climate, smooth roads, no traffic jams. In reality, replacement intervals depend on several factors:

• 🔥 Aggressive riding (sharp starts, towing) - reduces oil life by 30-40%.
• 🌡️ Extreme temperatures (frosts below -20°C or heat above +30°C) - accelerate the oxidation of the liquid.
• 🚗 Urban cycle with frequent stops - increases the load on the torque converter.
• 🛣️ Bad roads — vibrations and shocks contribute to the entry of metal shavings into the oil.

Optimal replacement intervals:

Replacement type	Mileage (km) / Time (years)	Signs of need
Partial replacement	40,000–50,000 / 3–4 years	Darkening of the oil, slight jerking when switching
Complete replacement	80,000–100,000 / 5–6 years	Burning smell, slipping, automatic transmission errors on the dashboard
Emergency replacement	Any mileage	Metal shavings on the dipstick, hum in the box, loss of traction

Critical error: many owners confuse the CVT JF015E with a classic automatic transmission. The variator requires a special fluid NS-2 or NS-3, not universal ATF! If you fill in the wrong oil, the variator belt will begin to slip after 5–10 thousand km.

What kind of oil to fill in automatic transmission Nissan Juke: original vs analogues

The choice of oil depends on the type of gearbox. For Nissan Juke There are three options available:

1. Original oil:
   • 🔧 Nissan Matic Fluid S (for classic automatic transmissions RE0F10A) — article KE908-99932.
   • 🔧 Nissan CVT Fluid NS-2 (for CVTs before 2014) - article number KE908-99945.
   • 🔧 Nissan CVT Fluid NS-3 (for CVTs after 2014) - article number KE908-99946.
2. Certified analogues (approved Nissan):
   • 🔧 Idemitsu CVTF (for CVTs) - complete analogue NS-2/NS-3.
   • 🔧 Ravenol CVT Fluid — improved anti-wear properties.
   • 🔧 Motul Multi CVTF - universal for most CVTs.
3. Universal ATF (only for classic automatic transmissions!):
   • 🔧 Toyota T-IV - compatible with Matic Fluid S.
   • 🔧 ZF Lifeguard 6 - for boxes RE0F10A.

Important: mix different types of oils (for example, NS-2 And NS-3) absolutely not! If you don’t know what was uploaded earlier, you need complete replacement with flushing.

⚠️ Attention: In CVTs Nissan Juke A special belt is used that is sensitive to the quality of the oil. Cheap analogues (for example, Lukoil CVT) can cause the belt to slip and the gearbox to fail after 20–30 thousand km.

Preparing for replacement: tools and consumables

To change the automatic transmission oil yourself Juke you will need:

New oil (6–8 liters for a complete change, 3–4 liters for a partial change)

Automatic transmission filter (part number 31726-3MX0A for variator)

Pan gasket (item no. 31397-3MX0A)

10, 14 and 17 mm wrenches (for drain plug and pan bolts)

Funnel with long hose (diameter 8–10 mm)

Waste container (minimum 5 l)

Torque wrench (for tightening the plug with a torque of 35–40 Nm)

Carburetor cleaner or kerosene (for flushing the pan)

Lint-free rags -->

If you plan complete replacement (using a device or the “draining” method), you will additionally need:

• 🔧 Compressor or pump for pumping oil.
• 🔧 Two hoses (one for supplying new oil, the second for draining).
• 🔧 Adapter for connecting to the automatic transmission cooling radiator.

Saving tip: The automatic transmission filter may not be changed during a partial replacement if the mileage is less than 80 thousand km and there are no metal shavings in the pan. However, when completely replacing the filter required - it becomes clogged with wear products and stops passing oil.

How to distinguish a fake automatic transmission filter?

Fake filters often have:

- Uneven seams on the body.

- No logo Nissan or unclear engraving.

- Too light weight (the original weighs ~200 g).

- O-ring made of low-quality rubber (cracks during installation).

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

Partial replacement is suitable for prevention and involves draining ~30–40% of the oil. Full algorithm:

1. Warm up the box.

   Start the engine, let it run for 5-7 minutes, then drive 5-10 km. The oil should heat up to 50–60°C (check with your hand - it’s hot, but not scalding).

2. Drain the old oil.

   Place the machine on a pit or lift. Unscrew the drain plug (14 mm wrench) and drain the oil into a container. Do not unscrew the plug completely at once - first loosen 1-2 turns so that the oil does not gush out under pressure.

3. Remove the pan.

   Unscrew the 16 bolts of the pan (10 mm wrench), carefully remove it - ~0.5 liters of oil remains in it. Clean the tray and magnets from shavings (use kerosene).

4. Replace the filter (optional).

   The filter is secured with 3 bolts (10 mm wrench). When removing, oil may leak - place a container. Install a new filter with a new gasket.

5. Reinstall the pan.

   It is better to replace the pan gasket (even if it is intact). Tighten the bolts crosswise to a torque of 8–10 Nm.

6. Fill with new oil.

   Fill in fresh oil through the filler neck (next to the battery). For a partial replacement, ~3.5 liters will be required. Use a funnel with a long hose.

7. Check the level.

   Start the engine, warm up the box (switch the selector to all positions with a delay of 3 seconds). Check the level on the dipstick - it should be between the marks HOT.

⚠️ Attention: If after changing the oil quickly turns black (within 1–2 thousand km), this is a sign severe wear of clutches. In this case, partial replacement is useless - a complete diagnosis of the box is required.

Complete automatic transmission oil change: draining method

A complete replacement is required when the mileage exceeds 80 thousand km or if the oil has a burning smell. To do this, use the pouring method (without a device):

1. Drain as much as possible.

   Repeat the steps for partial replacement, but after draining the oil through the plug, unscrew the automatic transmission radiator return hose (it is located to the right of the cooling radiator). Drain another ~1.5–2 liters.

2. Connect the hoses for flushing.

   Connect a hose to the radiator fitting to supply new oil (for example, from a compressor). Direct the second hose into the drain container.

3. Start circulation.

   Start the engine. Start pouring new oil through the funnel - it will displace the old oil through the return line. As soon as clean oil comes out of the hose, turn off the engine.

4. Rinse the box.

   Fill in 1–2 liters of special rinsing (for example, Liqui Moly ATF Reiniger), let the engine run for 5–10 minutes, then drain all the oil and fill with new oil.

Important: For a complete change, you will need 7–8 liters of oil (for a variator) or 6–7 liters (for a classic automatic transmission). After the procedure, be sure to reset the box adaptations via a diagnostic scanner (for example, Launch X431), otherwise jerking may occur.

Box type	Oil volume for a complete change (l)	Procedure time (min)
CVT JF015E	7.2–7.8	60–90
Automatic transmission RE0F10A	6.5–7.0	50–70

Common mistakes when changing oil and how to avoid them

Even experienced car owners make mistakes that can lead to automatic transmission failure. Let's look at the most common ones:

• 🔴 Overfilling or underfilling oil.

  Excess oil leads to foaming and loss of pressure, too little leads to oil starvation. Always check the level on a warm box!

• 🔴 Using the wrong oil.

  For example, fill Dexron III instead of NS-2 into the variator. This will cause the belt to slip and wear on the pulleys.

• 🔴 Untimely filter replacement.

  A clogged filter leads to a drop in oil pressure and accelerated wear of the solenoids.

• 🔴 Dirty tray.

  If you do not clean the magnets and the bottom of the pan from chips, they will get into the new oil and accelerate wear.

• 🔴 Failure to comply with temperature conditions.

  Checking the level on a cold box will give incorrect results. Warm up the oil to 50–60°C!

Consequences of errors:

• 🚨 Jerks when changing gears.
• 🚨 Error appears P0730 (incorrect automatic transmission operation).
• 🚨 Accelerated wear of the torque converter.

⚠️ Attention: If vibrations or noises occur after changing the oil, stop immediately and check the level! Perhaps too much oil got into the box and it foamed.

Signs that the automatic transmission oil needs to be changed urgently

If you notice at least one of these symptoms, the box requires urgent service:

• 🔥 Burning smell from oil on the dipstick - a sign of overheating and fluid degradation.
• 🔥 Jerks or delays when changing gears (especially when cold).
• 🔥 Hum or vibration when driving at a speed of 60–80 km/h.
• 🔥 Darkening of the oil until black or brown.
• 🔥 Automatic transmission errors on the dashboard (P0715, P0730, P0841).
• 🔥 Oil leaks from under the pan or oil seals.

If you ignore these signs, the consequences can be critical:

Symptom	Possible damage	Repair cost (from)
Jerks when switching	Friction wear	30 000 ₽
Burning smell	Torque converter overheating	50 000 ₽
Vibrations at speed	Wear of variator bearings	80 000 ₽
Oil leak	Damage to seals or pan	15 000 ₽

Critical case: if the oil on the dipstick has a metallic sheen or large particles (more than 1 mm) are found in the pan, the box is already in pre-emergency condition. In this case, changing the oil can only aggravate the problem - diagnostics are required at a service station.

FAQ: answers to frequently asked questions

Is it possible to pour automatic transmission oil into a variator? Nissan Juke?

No! CVT JF015E requires special fluid NS-2 or NS-3. Normal ATF (For example, Dexron) does not have the necessary friction properties and will cause the belt to slip. The consequences are jerking, loss of traction and failure of the variator.

How much oil is needed for a complete change in the variator Juke?

For a complete replacement using the flushing method, 7.2–7.8 liters will be required. If you use a device, it can take up to 9 liters (including washing). Always buy oil with a reserve - it’s better to have some left over than not enough.

Do I need to change the filter every oil change?

It is recommended to change the filter when complete replacement or if the mileage exceeds 80 thousand km. During partial replacement (every 40 thousand km), the filter can be left if it is clean. However, if there are a lot of chips in the pan or the oil is black, the filter necessarily replace.

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

The consequences depend on the mileage:

• 60–80 thousand km: jerks, delays when switching, increased fuel consumption.
• 100–120 thousand km: friction wear, slippage, errors P0730.
• 150+ thousand km: destruction of the planetary mechanism or variator belt, major repairs (from 100,000 ₽).

Is it possible to mix NS-2 And NS-3?

No, you can't mix! NS-3 has improved anti-friction additives, and when mixed with NS-2 a chemical reaction may occur leading to the formation of a precipitate. If you don’t know what was filled in previously, do a complete replacement with flushing.
