Changing the oil in a Nissan Almera N16 gearbox: timing, oil selection and step-by-step process

Nissan Almera N16 - a legendary sedan that still travels along the roads of the CIS thanks to its unpretentiousness. But even such an “indestructible” car has a weak point - gearboxwhich requires regular maintenance. Many owners do not change the transmission oil for years until jerking, humming, or shifting problems begin. In this article we will look at why does the Almera N16 with a RE4F03A automatic transmission need to change the oil every 60,000 km, and not “for the entire service life”, as they say in the manual.

We will tell you in detail how to change the oil yourself mechanical (FS5W71C) and automatic box, what tools you will need, and how to avoid common mistakes. We’ll also debunk the myths about “eternal” oil and explain why savings on gearbox maintenance are many times more expensive than repairs.

When to change the oil in the Almera N16 gearbox: official and real terms

Manufacturer in the manual for Nissan Almera N16 (2000–2006) indicates that oil in mechanical box (FS5W71C) is filled for the entire service life, and in automatic (RE4F03A) requires inspection every 100,000 km. But this optimistic recommendations for Europe with its mild climate and quality roads. In the realities of the CIS the situation is different:

• 🔧 Mechanical (FS5W71C): oil changes need to be done every 80–100 thousand km or once every 5 years. For aggressive driving or frequent traffic jams - every 60 thousand km.
• 🔄 Automatic (RE4F03A): partial replacement - every 40–50 thousand km, full (with removal of the pan) - once every 80–100 thousand km. If the oil turns black or smells like burning, replace it immediately!
• ⚠️ Signs of "tired" oil: jerks when switching, humming in the gearbox, difficult gear shifting (especially when cold), leaking seals.

Why such differences? B automatic transmission The oil not only lubricates, but also removes heat and also serves as a working fluid for the torque converter. When overheated, it loses its properties, and wear products clog the solenoids. B mechanics the process is slower, but metal shavings still accumulate.

⚠️ Attention! If you bought Almera N16 with mileage and don’t know when the last time the oil in the box was changed, do this immediately. Even if everything works fine on the outside, accelerated wear may already be occurring inside.

What kind of oil to fill in the Nissan Almera N16 gearbox: compatibility table

Oil selection is a critical step. The wrong viscosity or type of fluid can kill a box within a few thousand kilometers. For Almera N16 The following oils are suitable:

Box type	Original oil	Analogues (recommended)	Volume, l	Viscosity
Mechanical (FS5W71C)	Nissan MTF HQ Multi 75W-80	Mobil Mobilube 1 SHC 75W-90 Castrol Syntrans Transaxle 75W-90 Liqui Moly Hochleistungs-Getriebeoil 75W-90	2.8–3.0	75W-80 or 75W-90
Automatic (RE4F03A)	Nissan Matic Fluid D	Idemitsu ATF Type-J Ravenol ATF D2/D3 Aisin ATF AFW+	7.0–7.5 (partial) 9.5–10.0 (full)	—

For automatic transmission RE4F03A it is strictly forbidden to use universal ATF fluids such as Dexron III or Mercon V. They are not compatible with the clutches of this gearbox and will lead to gear slipping. Exception - Idemitsu Type-J, which is a complete analogue Nissan Matic D.

B manual box you can fill in oils with approval GL-4 or GL-5, but it is better to give preference to specialized transmission fluids for Nissan. Synthetics (75W-90) is preferable to semi-synthetics, especially in cold climates.

Tools and consumables for changing the oil in the Almera N16 gearbox

To change the oil in the box yourself, you will need:

• 🔧 Tools:
  • Allen key on 10 mm (for mechanical drain plug).
  • Head or key 14 mm (for filler plug).
  • Socket wrench on 10 mm (to remove the machine tray).
  • Torque wrench (optional for proper tightening).
  • Funnel with extension (for pouring oil into the machine).
  • Container for draining waste (minimum 5 liters for manual, 10 liters for automatic).
• 🛢️ Consumables:
  • New oil (see table above for volume).
  • Automatic transmission pan gasket (Nissan 31397-31X01) or sealant (Loctite 574).
  • Automatic transmission filter (Nissan 31726-31X00 or equivalent JS Asakashi JT506K).
  • Drain plug O-ring (Nissan 11026-01M02).
  • Gloves and rags.

For complete automatic oil change Additionally you will need:

• 🔄 A special washing device (or a hose for manual pumping).
• 🔧 Key for removing the torque converter (if you plan to flush).

⚠️ Attention! Do not use cheap analogues of automatic transmission filters - they may crumble inside the box. It’s better to overpay for the original or a proven brand (JS Asakashi, Febi, Mahle).

Warm up the box (drive 10–15 km)

Drive the car onto a pit/overpass

Step-by-step instructions: changing the oil in an Almera N16 manual transmission

Oil change process mechanical box FS5W71C easier than with an automatic machine and takes about 1 hour. Follow the algorithm:

1. Warm up the oil. Drive 10-15 km until it becomes liquid and drains better.
2. Drive the car onto a pit or overpass. Place the handbrake on and place chocks under the wheels.
3. Remove the crankcase protection (if any). It is secured with 4–6 bolts.
4. Find the drain plug — it is located on the transmission pan closer to the rear of the car. Place the container.
5. Unscrew the plug with a 10 mm hexagon and drain the oil. Be careful - it's hot!
6. Screw in the drain plug with a new O-ring. Tightening torque - 30–40 Nm.
7. Unscrew the filler plug (located above the drain, closer to the cabin).
8. Fill with new oil using a funnel. For FS5W71C ~2.8 liters will be required.
9. Screw in the filler plug and check the level.

To check the oil level in manual transmission, unscrew the filler plug - the liquid should be at the level of the lower edge of the hole. If there is not enough oil, add more.

What to do if the oil does not drain from the mechanics?

If the oil does not flow or flows very slowly, the drain plug or magnet may be clogged. Clean it carefully with wire. If the problem is thick oil, warm up the box longer (20–30 km drive).

Step-by-step instructions: changing the oil in an Almera N16 automatic transmission

Changing the oil in automatic transmission RE4F03A more complicated and can be done in two ways: partial (without removing the pan) and full (with removing the pan and replacing the filter). We recommend complete replacement, since it allows you to remove up to 90% of the waste liquid.

Partial replacement (without removing the pan)

1. Warm up the automatic transmission (drive 10–15 km).
2. Lift the car on a lift or drive it into a pit.
3. Remove the crankcase protection.
4. Find the drain plug on the automatic transmission pan (also known as the control plug). Unscrew it with the key to 14 mm.
5. Drain ~3.5–4 liters of oil (half the volume).
6. Screw the plug with a new O-ring.
7. Fill in new oil through the filler hole (located on top, under the hood, next to the battery). Use a funnel with an extension.
8. Check the level on the dipstick (should be between MIN And MAX on a warm gearbox).

Complete replacement (with removal of pan and filter)

1. Drain the oil through the drain plug (as in a partial replacement).
2. Unscrew all bolts of the automatic transmission pan (using a socket wrench 10 mm). Be careful - ~1 liter of oil will remain in the pan!
3. Remove the pan and clean it of old sealant and metal shavings. Check the magnets - if they are clogged, the box is already worn out.
4. Replace the automatic transmission filter (it is secured with 3 bolts inside the box).
5. Install a new pan gasket or apply sealant (Loctite 574).
6. Tighten the pallet (the tightening torque of the bolts is 10–12 Nm).
7. Fill in new oil through the filler hole. A complete replacement will require ~9.5–10 liters.
8. Warm up the gearbox (start the engine, switch all selector modes with a delay of 5 seconds).
9. Check the level on the dipstick and add if necessary.

After a complete change, the oil in the automatic transmission will be light and the shifts will be smooth. If the jerking continues, the gearbox may already be worn out and requires diagnostics.

Typical mistakes when changing oil in the Almera N16 gearbox

Even experienced car owners sometimes make mistakes that lead to box failure. Here are the most common:

• 🚫 Wrong choice of oil. For example, fill Dexron III instead of Nissan Matic D in automatic transmissions leads to clutch slippage and overheating.
• 🚫 Underfilling or overfilling of oil.
  • B mechanics a low level leads to oil starvation and gear wear.
  • B automatic Overfilling causes oil foaming and loss of pressure.
• 🚫 Ignoring the replacement of the filter in the automatic transmission. An old filter does not clean the oil, and wear products circulate throughout the system.
• 🚫 Tightening the pan bolts tightly. This deforms the gasket and causes leakage. Tightening torque - no more 12 Nm!
• 🚫 Change the oil to cold. The cold oil is not completely drained, and up to 30% of the waste remains in the box.

⚠️ Attention! If, after changing the oil, jerks appear in the automatic transmission or the box begins to “kick”, it is possible that the wrong oil was filled in or its level is incorrect. Check immediately and repeat the procedure if necessary.

The cost of changing the oil in the Almera N16 gearbox: independently vs service

The price of an oil change depends on the type of gearbox and replacement method. Let's look at the estimated costs:

Gearbox type	Replacement method	Oil cost	Cost of work (service)	Total (independent)	Total (service)
Mechanics	Complete replacement	1 500–2 500 ₽ (3 l Nissan MTF HQ)	800–1 500 ₽	1 500–2 500 ₽	2 300–4 000 ₽
Automatic	Partial replacement	2 500–3 500 ₽ (4 l Nissan Matic D)	1 500–2 500 ₽	2 500–3 500 ₽	4 000–6 000 ₽
Automatic	Complete replacement (with pan removal)	5 000–7 000 ₽ (10 l Nissan Matic D + filter)	3 000–5 000 ₽	5 000–7 000 ₽	8 000–12 000 ₽

Replacing it yourself is more profitable, but requires time and care. In the service, you overpay for the work, but receive a guarantee (if the technician did not make a mistake with the oil). For automatic transmission We recommend a complete replacement - it is more expensive, but it extends the life of the automatic transmission by 100+ thousand km.

Frequently asked questions (FAQ)

Is it possible to mix different oils in an Almera N16 automatic transmission?

No, mix oils in automatic transmission absolutely not possible. Different ATF fluids have different additives, and mixing them can cause a chemical reaction leading to sludge or loss of properties. If you do not know what oil was previously filled, check complete replacement with washing.

How to check the oil level in a manual transmission if there is no dipstick?

B mechanical box FS5W71C The oil level is checked through the filler hole. Unscrew the plug (the key is on 14 mm) - the oil should be at the level of the lower edge. If it is not visible, add until it begins to flow out.

What happens if you don’t change the oil in the Almera N16 automatic transmission?

If you ignore changing the oil in automatic transmission, the consequences will be dire:

• 🔥 Overheating of the gearbox due to loss of heat-dissipating properties of the oil.
• 🔧 Wear of clutches and solenoids, leading to jerks and delays when switching.
• 💥 Torque converter breakdown (repair cost - from 30,000 ₽).
• 🚗 Complete failure of the automatic transmission (major repairs will cost 50,000–80,000 ₽).

The first symptoms are kicks when switching, burning smell And dark oil color.

What kind of oil should I fill in the Almera N16 automatic transmission if I don’t have the original Nissan Matic D?

The best analogues for RE4F03A:

• Idemitsu ATF Type-J - complete analogue, recommended by ourselves Nissan.
• Ravenol ATF D2/D3 - German quality, suitable for difficult conditions.
• Aisin ATF AFW+ - used on conveyors Toyota, compatible with Nissan.

Do not take it under any circumstances Dexron VI or universal ATF - they are not compatible!

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

Automatic transmission flushing RE4F03A needed only in two cases:

1. If the oil is heavily contaminated (black, with a burning smell).
2. If you do not know what oil was filled previously.

For rinsing use special apparatus or method double replacement (drained - filled with a new one - drove 500 km - drained and filled again). Do not use aggressive flushing fluids - they can damage the seals!
