Transfer case oil for <em>Nissan Terrano 3</em>: how to choose and replace correctly

Nissan Terrano 3 — one of the most popular crossovers on the Russian market, known for its reliability and cross-country ability. However, even such a tough car requires regular maintenance, especially when it comes to the transmission. The transfer case (transfer case) is a key component of the all-wheel drive system, the condition of which determines the smoothness of mode switching and the service life of the entire transmission.

Many owners Terrano 3 are faced with the question: what kind of oil to fill in the transfer case, how often to change it, and is it possible to save money on analogues? In this article we will look at official recommendations Nissan, we will analyze the best oils for the transfer case, and also give step-by-step replacement instructions, taking into account typical mistakes. We will pay special attention oil compatibility with the clutch All Mode 4×4-i, which is installed on Terrano 3 since 2014.

Official requirements Nissan to the oil in the distributor Terrano 3

The manufacturer clearly regulates which oil should be used in the transfer case Nissan Terrano 3. According to the service documentation, for models with manual transmission (code RS5F92R) and transfer case (code PT500) recommended:

• 🔹 Original oil: Nissan Differential Gear Oil Hypoid Super GL-5 80W-90 (art. KE908-99932).
• 🔹 Alternative Standards: oil must match API GL-5 and viscosity SAE 80W-90 or 75W-90 (for cold climates).
• 🔹 Refill volume: 0.9–1.0 l (depending on the year of manufacture and modification).

It is important to consider that for Terrano 3 with the system All Mode 4×4-i (electronic clutch) the requirements are stricter: the oil must have increased anti-wear properties and compatibility with clutch friction materials. The use of uncertified oils may result in clutch slippage or its premature wear.

⚠️ Attention! In handouts Terrano 3 Model years 2017–2023 use oil with additives for electronic clutches. Replacement with regular one GL-5 no markings "for AWD" may cause an error C1101 (all-wheel drive system malfunction).

When and how often to change the oil in the transfer case?

According to the regulations Nissan, oil in transfer case Terrano 3 need to change:

• 🔧 Every 90,000 km mileage (or once every 6 years) - for standard operating conditions.
• 🔧 Every 60,000 km — if the car is used in difficult conditions (frequent off-road driving, towing, extreme temperatures).
• 🔧 Every 40,000 km - for models with All Mode 4×4-i (dealer recommendation Nissan for Russia).

However, there are signs that indicate the need early replacement:

• 🚨 Noise or hum when driving at a speed of 40–60 km/h (especially in 4WD Lock).
• 🚨 Difficulty switching transfer modes (with 2WD on 4WD).
• 🚨 Darkening of the oil or the presence of metal shavings on the dipstick.

⚠️ Attention! If, after changing the oil, the transfer case appears crunch when turned on 4WD, this may indicate incompatibility of the oil with the clutch All Mode 4×4-i. In this case, the system must be flushed and replaced with original oil. Nissan.

Step-by-step instructions for changing the oil in the transfer case

Changing the oil in the transfer case Nissan Terrano 3 - a procedure that can be performed independently with a minimum set of tools. You will need:

• 🔧 Allen key on 10 mm (for drain plug).
• 🔧 Ratchet wrench with head on 24 mm (for filler plug).
• 🔧 Oil syringe (or funnel with flexible tube).
• 🔧 Container for draining waste (volume of at least 1.5 l).
• 🔧 New oil (1 l) and sealing rings for plugs (art. 11026-01M02).

Replacement process:

1. Warm up the car (drive 5–10 km) so that the oil becomes less viscous and drains better.
2. Place the machine on a pit or lift. Secure the wheels with chocks.
3. Remove the crankcase protection (if installed). In some modifications Terrano 3 To access the transfer case, you need to remove part of the plastic fender liner.
4. Unscrew the drain plug (lower plug on the transfer case) and drain the oil into a container.
5. Wipe the drain plug magnet from metal shavings (its presence is normal for mileage over 100 thousand km).
6. Screw in the drain plug with a new O-ring.
7. Unscrew the filler plug (upper plug) and use a syringe to fill in new oil to the level of the lower edge of the hole.
8. Screw in the filler plug and check for leaks.

After changing the oil be sure to check the operation of the distributor:

• 🔄 Switch modes 2WD → AUTO → 4WD Lock on the move (speed 20–30 km/h).
• 🔄 Make sure there are no extraneous noises or vibrations.
• 🔄 Check for oil leaks under the distributor.

What should I do if the transfer case is noisy after changing the oil?

If a hum or crunching noise appears after changing the oil, possible causes:

1. **Insufficient oil level** - add to normal level.

2. **Incorrect viscosity** - for example, instead of 80W-90, 75W-80 is filled.

3. **Air getting into the system—it is necessary to flush out the oil by switching the transfer case modes while parked.

4. **Bearing wear** - if the noise does not disappear, diagnostics are necessary.

Typical mistakes when changing the oil in the transfer case Terrano 3

Even experienced car owners sometimes make mistakes that can lead to serious damage. Here are the most common:

• ❌ Use of oil GL-4 instead of GL-5 - this leads to accelerated wear of gears and bearings.
• ❌ Overfilling or underfilling oil - both lead to increased pressure and leaks.
• ❌ Ignoring replacement of o-rings - old rings can leak after 1–2 thousand km.
• ❌ Mixing oils of different brands - this disrupts the chemical composition of the additives.
• ❌ Changing the oil on a cold engine — in this case, no more than 60% of the waste is drained.

The error with incompatible clutch oil All Mode 4×4-i. For example, if you fill in the usual GL-5 without electronic clutch additives, the system can start "twitch" when switching modes, and an error appears on the panel 4WD System Malfunction.

⚠️ Attention! If after changing the oil an error appears on the instrument panel C1101 or C1105, contact your dealer immediately! These codes indicate a malfunction of the all-wheel drive clutch, which can be “killed” by incorrect oil within 1–2 thousand km.

How to check the level and condition of the oil in the transfer case?

Unlike the engine, the transfer case Nissan Terrano 3 does not have a dipstick - the oil level is checked through the filler hole. Here's how to do it right:

1. Place the car on flat surface (no slope!).
2. Clean the area around the filler plug of dirt (to prevent debris from getting into the transfer case).
3. Unscrew the filler plug with a wrench 24 mm.
4. The oil level should be at the bottom edge of the hole. If the oil is not visible, there is not enough oil.
5. Assess the condition of the oil:
   • ✅ Norm: transparent, amber color, without burning odor.
   • ❌ Needs replacement: dark, with metal shavings or a burnt smell.

If the oil has milky shade, this indicates water ingress (for example, after deep puddles). In this case it is required complete oil change with flushing handouts.

Answers to frequently asked questions (FAQ)

Is it possible to use manual transmission oil in the transfer case? Terrano 3?

No! Manual transmission oil (API GL-4) is not suitable for transfer cases, as it does not have sufficient anti-wear properties for gears with hypoid gearing. Use only GL-5.

How much oil to pour into the transfer case Nissan Terrano 3 2020?

For models 2017–2023, the oil volume in the transfer case is 0.95 l. However, with a complete replacement (including draining the differential), up to 1.1 liters may be required.

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

If you ignore the oil change:

• 🔴 The wear of gears and bearings increases.
• 🔴 Noise and vibration occurs when moving.
• 🔴 Coupling All Mode 4×4-i may fail (repair cost - from 50 thousand rubles).
• 🔴 In critical cases, the distributor will jam, which will lead to an accident.

Is it possible to mix oils from different manufacturers?

Mix oils not recommended, especially if they have a different base (mineral + synthetic). As a last resort, topping up is allowed no more than 10% from the volume of oil of the same class (GL-5) and viscosity.

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

Flushing is required only in three cases:

• 🔹 When switching from mineral oil to synthetic oil.
• 🔹 If a lot of metal shavings are found in the old oil.
• 🔹 After repairing the distributor (replacing bearings, seals).

For flushing, use special transmission flushing oil (for example, Liqui Moly Getriebe-Reiniger).
