<em>Nissan Murano Z52</em>Transfer Box Oil Change: A Complete Owners Guide

Transfer case in Nissan Murano Z52 - a node that is often left without proper attention until it begins to “signal” problems with noise or leaks. Meanwhile, timely change of oil in the transfer case not only extends the life of the unit, but also prevents expensive repairs to the all-wheel drive. Unlike an engine or automatic transmission, where service intervals are clearly stated in the manual, with a transfer case, owners often have questions: what kind of oil to use, how often to change it, and whether it is possible to do it yourself.

This article will debunk myths and give practical recommendations for changing the oil in the transfer case Murano Z52 (2015–2023). We will figure out why the factory limit of 90,000 km is not always the best option for Russian conditions, what transmission oils compatible with the unit JF011E (installed on most versions), and we will show the step-by-step replacement process, taking into account typical errors. If you have never serviced a transmission, don’t worry: with the right approach, the procedure will take no more than an hour.

Why is it important to change the oil in the transfer case? Murano Z52?

Transfer case in Nissan Murano works in close cooperation with the automatic transmission and rear differential, distributing torque between the axles. Unlike the mechanical transfer case of old SUVs, it uses Haldex hydraulic coupling, which is extremely sensitive to the quality and viscosity of the oil. Over time, the liquid loses its properties:

• 🔥 Oxidation and deposit formation — at high temperatures (for example, when towing), the oil decomposes, clogging the valve body channels.
• ❄️ Loss of viscosity — cold oil thickens, which leads to delays in all-wheel drive response.
• 🛑 Clutch friction wear — particles of metal and friction material circulate in the oil, accelerating wear of the unit.

The first symptoms of “tired” oil do not appear immediately. At first you may notice jerking when switching 4WD modes (especially on slippery surfaces), then hum or vibration at speeds above 80 km/h. In advanced cases, the transfer case goes into emergency mode and lights up on the dashboard 4WD ERROR. Unlike an automatic transmission, where you can “add up oil and go”, in the transfer case Murano Z52 a critically low fluid level leads to instant failure of the hydraulic coupling.

⚠️ Attention: If, after changing the oil, the transfer case begins to “kick” or make a grinding noise, the new oil is probably incompatible with the remnants of the old one. In this case it is required complete flushing of the system (about 3-4 volumes of oil).

What kind of oil to pour into the transfer case? Nissan Murano Z52?

The factory manual instructs to use Nissan Transfer Fluid KE908-99932 (article number for original liquid). However, in practice, owners successfully use analogues from other brands. The main thing is to comply JWS 3309 specification or Type TF, which guarantees compatibility with the hydraulic coupling Haldex.

Brand	Article	Volume, l	Notes
Nissan	KE908-99932	1	Original, optimal for warranty service
Mobil	ATF 3309	1	Complete analogue, often cheaper than the original
Ravenol	TF-0870	1	High temperature stability, suitable for harsh environments
Motul	Multi ATF	1	Versatile, but requires more frequent replacement

Oil volume in transfer case Murano Z52 — 0.7–0.8 liters (the exact volume depends on the degree to which the old fluid is drained). Some owners save by filling ATF for automatic transmission (For example, Dexron III), but this is fraught clutch slippage and accelerated wear. If you choose an analogue, check for approval JWS 3309 on the packaging.

When to change the oil: regulations and real terms

Official regulations Nissan prescribes the first oil change in the transfer case to 90,000 km, and subsequent ones - every 60,000 km. However, these figures are calculated for “ideal” operating conditions: smooth roads, moderate climate and no load. In reality, the intervals should be shortened:

• 🏔️ Driving on off-road or snow - replacement every 40,000–50,000 km.
• 🚛 Towing a trailer — reduce the interval by 30% (up to 40–45 thousand km).
• 🌡️ Extreme temperatures (below -30°C or above +35°C) - check the level every 20,000 km.

How to determine when it's time to change the oil ahead of schedule?

• 🔍 Color: fresh oil - reddish or amber; if it turns black or becomes cloudy, replace it immediately.
• 👃 Smell: A burnt odor indicates overheating and degradation of the additives.
• 💧 Consistency: If thick deposits or metal shavings remain on the dipstick, the oil has lost its properties.

⚠️ Attention: After changing the oil in the transfer case Murano Z52 be sure to follow Haldex coupling adaptation procedure via a diagnostic scanner (for example, Launch X431 or Delphi). Without this, there may be jerks when engaging all-wheel drive.

Preparing for replacement: tools and consumables

To change the oil in the transfer case yourself Nissan Murano Z52 you will need:

10 mm hex wrench (for drain plug)|24 mm socket wrench (for fill plug)|New oil (0.8–1 l)|New sealing washer for drain plug (part number 11026-01M02)|Funnel with flexible hose (diameter 8–10 mm)|Drain container (volume at least 1 l)|rags and gloves|Diagnostic scanner (optional, for adapting the coupling)-->

Pay special attention sealing washer. Many owners ignore replacing it, but this leads to oil leaks after 5–10 thousand km. Original washer from Nissan will cost 50–100 rubles, but will save you nerves and money on fixing the leak.

If you are planning complete oil change (with washing), additionally prepare:

• 🔧 Oil injection syringe (for flushing through the filler hole).
• 🧴 Carburetor Cleaner (for washing magnets and internal surfaces).

Step-by-step instructions for changing the oil

The procedure for changing the oil in the transfer case Murano Z52 takes about 40–60 minutes. Follow the algorithm:

1. Preparing the car:

   Place the machine on flat surface (lift or inspection hole). Secure the wheels with chocks. If you are using a jack, lift it the entire front partso that the transfer case is horizontal.

2. Draining old oil:

   Place a container under the drain hole (located at the bottom of the transfer case, closer to the driveshaft). Unscrew the plug with a 10 mm wrench. Be careful — the oil may be hot! Wait until it drains completely (5–10 minutes).

3. Cleaning magnets and plugs:

   At the bottom of the drain plug there are magnetsCollecting metal shavings. Clean them carefully with a cloth soaked in cleaner. If there are a lot of chips, this is a sign of wear on the bearings or gears.

4. Filling with new oil:

   Install a new sealing washer onto the drain plug and tighten it torque. 30–40 Nm. Fill in new oil through the filler hole (24 mm plug) using a funnel. Volume - until the liquid begins to flow back.

5. Level check:

   Tighten the filler plug and start the engine. Switch transfer modes (2WD → AUTO → LOCK) several times. Stop the engine, unscrew the filler plug and add oil to the level of the edge of the hole.

If you notice that the new oil quickly turns black (after 1–2 thousand km), this means that there are deposits left in the transfer case. In this case it is recommended re-replacement with washing.

What to do if you can’t unscrew the plug?

If the drain or filler plug is stuck, do not use excessive force - you risk breaking the thread. Treat the plug with a penetrating lubricant (for example, WD-40) and wait 15–20 minutes. If that doesn't help, use an impact wrench with a hex socket. In extreme cases, you will have to drill out the plug and cut a new thread (you will need a repair kit).

Common mistakes and how to avoid them

Even experienced car owners make mistakes when changing the oil in the transfer case. Murano Z52. Here are the most common:

• 🔧 Cork retightening — leads to thread failure or deformation of the aluminum transfer case housing. Tightening torque: 30–40 Nm for drain plug, 40–50 Nm for filler plug.
• 🛢️ Underfilling or overfilling of oil - both are harmful. If the coupling is underfilled Haldex It works “dry”; if it is overfilled, the oil foams and loses its properties.
• 🧲 Ignoring magnets — if you do not clean the magnets from chips, they will get into the new oil and accelerate wear.
• 🔄 Lack of clutch adaptation — after changing the oil, the electronic control unit needs to “learn” new viscosity parameters.

Critical error: using oil without JWS 3309 approval. Even if the viscosity is the same (for example, ATF Dexron VI), the lack of special additives leads to clutch slippage and overheating.

Adaptation of the Haldex coupling after an oil change

After changing the oil in the transfer case Nissan Murano Z52 must be completed adaptation procedure hydraulic coupling. Without this, the electronic control unit will use old calibration data, which will lead to:

• ⚡ Jerks when turning on all-wheel drive.
• 🔥 Overheating of the coupling due to incorrect pressure.
• ❌ False errors C1105 or C1110 on the dashboard.

For adaptation you will need a diagnostic scanner with protocol support Nissan Consult (For example, Launch X431 Pro or Autel MaxiCOM). Procedure:

1. Connect the scanner to the diagnostic connector (located under the steering wheel).
2. Select module 4WD/AT (or Transfer).
3. Find the function Haldex Clutch Adaptation or Transfer Fluid Reset.
4. Follow the instructions on the screen (usually you need to press the brake pedal and hold it for 10-15 seconds).

If you don’t have a scanner, you can try to “teach” the clutch manually:

1. Start the engine and warm it up to operating temperature.
2. Switch the transfer case to mode LOCK and drive 50–100 meters on a flat road.
3. Return to mode AUTO and repeat the cycle 2-3 times.

This method is less effective, but will help avoid serious mistakes in all-wheel drive operation.

FAQ: Frequently asked questions about changing the oil in the transfer case Murano Z52

Is it possible to mix different oils in the distributor?

No, mix oils of different brands or specifications absolutely not recommended. Even if both oils meet the approval JWS 3309, additives may react, resulting in sediment formation or loss of properties. If you urgently need to add oil, use just the same brand, which is already filled.

What happens if you don’t change the oil in the transfer case?

If you ignore changing the oil in the transfer case Murano Z52 At first, “mild” symptoms will appear: jerking when turning on all-wheel drive, rumbles at speed. 20–30 thousand km after the expiration of the oil service life, irreversible processes:

• Wear of clutch friction discs Haldex (repair - from 50,000 rubles).
• Jamming of the drive shaft bearings (replacement of the transfer case assembly - from RUB 150,000).
• Damage to the hydraulic pump (the control unit may fail).

How to check the oil level in a transfer case without a pit?

Check the oil level in the transfer case Murano Z52 It is possible without an inspection hole, but it is less convenient:

1. Raise the front of the car on a jack (be sure to secure the rear wheels!).
2. Remove the engine protection (if installed).
3. Unscrew the filler plug (24 mm wrench) - the level should be at the edge of the hole.

Important: the car must be parked strictly horizontal, otherwise the readings will be incorrect.

Do I need to flush the transfer case when changing the oil?

Flushing the transfer case recommended, if:

• The oil has not been changed for more than 100,000 km.
• Metal shavings or thick deposits are visible in the drained fluid.
• The transfer case worked with constant overheating (off-road driving, towing).

For rinsing use special liquid (For example, Liqui Moly Getriebe-Reiniger) or the same oil that you will fill. Procedure:

1. Drain the old oil.
2. Fill in flushing fluid (0.5 l).
3. Start the engine, turn on the mode LOCK and let it work for 5-10 minutes.
4. Drain the flush and fill with new oil.

What kind of oil is poured into the Murano Z52 transfer case from the factory?

From factory to distributor Nissan Murano Z52 original oil is poured Nissan Transfer Fluid KE908-99932 (specification JWS 3309).
