Changing the oil in an automatic transmission Nissan Almera Classic: a complete guide with photos and videos

Automatic transmission Nissan Almera Classic (N16) is one of the most reliable units in the Japanese manufacturer’s line, but only subject to timely maintenance. Many owners mistakenly believe that There is no need to change the automatic transmission oil, because the service book often states “for the entire service life.” However, real experience shows that ignoring replacement leads to jerks during switching, overheating and expensive repairs already within 150–200 thousand km.

In this article you will find step-by-step instructions for changing the oil (both partial and complete), recommendations for choosing a fluid, a list of necessary tools and unique nuances for Almera Classic with 1.5 and 1.8 l engines. We will also look at common mistakes that even experienced car owners make, and give advice on how to extend the life of the box without visiting a service station.

When to change the oil in an Almera Classic automatic transmission: signs and regulations

Official regulations Nissan for Almera Classic (2006–2018) does not provide for changing the oil in the automatic transmission, but this is a marketing ploy. In practice the liquid loses its properties already after 60–80 thousand km, and by 100 thousand km problems begin. Here are the key signs that it's time to act:

• 🔴 Jerks or delays when changing gears (especially from 1st to 2nd).
• 🔴 Vibration or extraneous noise (hum, grinding) when moving.
• 🔴 Burning smell from oil (checked with a dipstick).
• 🔴 Dark liquid color (should be red-amber, not black).
• 🔴 Oil leaks under the box (stains on the asphalt after parking).

Experts recommend adhering to the following intervals:

Replacement type	Interval (km)	Notes
Partial replacement	40–50 thousand	Suitable for prevention, renews 30–40% of the oil.
Complete replacement	80–100 thousand	Requires flushing of the system, replaces up to 90% of the fluid.
Emergency replacement	When showing signs of wear	If the oil turns black or smells burning.

It is important to take into account the operating conditions: in city traffic with traffic jams or when towing a trailer, the oil ages faster. If you often drive off-road or in hot weather (+30°C and above), reduce the interval by 20–30%.

⚠️ Attention: If the automatic transmission has already experienced jerking, changing the oil may temporarily worsen the problem. This is due to the fact that the new fluid flushes away deposits that clog the solenoids. In this case, after replacement it may be necessary box adaptation (reset errors via Nissan Consult or similar scanners).

What kind of oil to fill in Almera Classic automatic transmission: original vs analogues

Box RE4F03A, installed on Almera Classic, demanding on oil quality. The official manufacturer recommends Nissan Matic Fluid D (article KLE22-00004), but there are worthy analogues on the market:

• 🔹 Idemitsu ATF Type-J - a complete analogue of the original, used on the assembly line.
• 🔹 Mobil ATF 3309 — universal oil, suitable for most automatic transmissions Nissan.
• 🔹 Castrol Transmax J — improved anti-wear properties.
• 🔹 Liqui Moly Top Tec ATF 1200 — premium segment, extends the life of solenoids.

Oil volume to change:

• 🔧 Partial replacement: 3–4 l (depending on drainage method).
• 🔧 Full replacement: 7–8 l (with rinsing).

Important: Do not mix oils from different manufacturers! If you don't know what was uploaded earlier, do complete replacement with flushing. Also avoid generic fluids like Dexron III - they do not meet the requirements Jatco (automatic transmission manufacturer for Nissan).

Tools and consumables: complete list for replacement

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

New oil (4–8 l depending on the type of replacement)|New automatic transmission filter (part number 31726-31X01)|Pan gasket (art. no. 31397-31X00)|10 mm wrench (for pan bolts)|24 mm socket (for drain plug)|Funnel with long hose (for filling)|Drain container (minimum 5 l)|Lint-free rag|Torque wrench (optional, for precise tightening)|Scanner for error reset (if adaptation required)-->

If you plan complete replacement, you will additionally need:

• 🔧 Washing plant (you can rent or make a homemade one from an old oil pump).
• 🔧 New O-rings for automatic transmission cooling radiator (article no. 31728-31X00).

Advice: Before purchasing a filter, check its compatibility with your box. On Almera Classic two types of filters were installed - metal (early models) and plastic (after 2010). To avoid mistakes, take a photo of the old filter before purchasing.

⚠️ Attention: Do not use sealant instead of pan gasket! Even if it looks intact, over time the rubber seal hardens and begins to leak oil. The cost of a new gasket (~300 rubles) is not comparable with the risk of damage to the box due to a leak.

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

Partial replacement is suitable for prevention and renews ~30–40% of the oil. The procedure takes 1–1.5 hours and does not require special equipment.

Step 1. Warm up the oil

Start the engine and let it run for 5-10 minutes. Switch the automatic transmission selector through all modes (P → R → N → D → L), holding each for 3–5 seconds. This will help the oil distribute evenly throughout the system.

Step 2. Drain the old oil

1. Stop the engine and place a container under the drain plug (it is located on the automatic transmission pan).
2. Unscrew the plug with a 24 mm wrench. Be careful - the oil is hot!
3. Wait until it drains completely (usually ~3 liters flow out).

Step 3: Replace the filter and gasket

1. Unscrew the pan bolts (10 mm wrench) and carefully remove it. ~0.5 liters of oil will remain inside - drain it into a container.
2. Remove the old filter (it is secured with 3 bolts). Clean any metal shavings from the magnets at the bottom of the tray.
3. Install a new filter and gasket. Tighten the bolts in a cross pattern to avoid distortion.

Step 4. Filling with new oil

1. Insert a funnel into the filler hole (it is located next to the battery, under the hood).
2. Fill in fresh oil in a volume equal to the drained amount (usually 3–3.5 l).
3. Start the engine and go through all selector modes again.
4. Check the level on the dipstick - it should be between the marks MIN And MAX on a heated box.

Complete automatic transmission oil change: displacement method

A complete replacement is required if the oil is heavily contaminated or after 100 thousand km. To do this, the method of displacing the old fluid with a new one is used using a flushing unit or (in garage conditions) by repeated draining/filling.

Method 1: Using installation (optimal)

1. Connect the unit to the automatic transmission cooling radiator pipes (they need to be disconnected from the box).
2. Start the engine and start flushing. The installation will pump new oil, displacing the old one.
3. Monitor the color of the liquid at the outlet - as soon as it becomes light, the process is complete.
4. Drain the remaining oil through the plug and replace the filter (as in a partial replacement).

Method 2: Without installation (for garage)

This method requires patience and a large amount of oil (up to 12 l):

1. Perform partial replacement (as described above).
2. Drive 20–30 km to allow the new oil to mix with the old.
3. Repeat draining and filling 2-3 more times until the oil is light in color.

Important: After a complete replacement it may be necessary reset automatic transmission adaptations. To do this:

1. Disconnect the battery terminal for 10 minutes.
2. Connect the scanner (for example, Launch X431) and follow the procedure AT Reset.
3. Drive 50–100 km in a gentle mode (without sudden acceleration).

Common mistakes when changing oil and how to avoid them

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

• ❌ Overfilling or underfilling oil. Consequences: foaming, loss of pressure, accelerated wear of friction clutches.

  ⚠️ Attention: Automatic transmission oil level Almera Classic being checked only on a warm box (oil temperature 60–80°C). A cold test will give the wrong result!

• ❌ Using the wrong oil. For example, Dexron VI instead of Matic D leads to jamming of the solenoids.
• ❌ Late filter replacement. The old filter becomes clogged with wear products, which leads to oil starvation.
• ❌ Tightening the pan bolts without a torque wrench. Over-tightening deforms the pallet; under-tightening leads to leaks.
• ❌ Ignoring automatic transmission adaptation after a complete replacement. This may cause kicking when shifting.

What to do if the automatic transmission jerks after changing the oil?

If jerking occurs after replacement, this may be due to:

1. **Incorrect oil level** - check the dipstick on a warm box.

2. **Contamination of the solenoids** - the old fluid has washed away the deposits that clogged the channels. The solenoids need to be flushed or replaced.

3. **Unreset adaptations** - reset via a scanner or by disconnecting the battery.

4. **Poor-quality oil** - if a cheap analogue was used, replace it with the original Nissan Matic D.

The cost of changing the oil in an Almera Classic automatic transmission: service vs independently

Prices for changing automatic transmission oil vary depending on the region and type of service:

Replacement type	Cost in service (₽)	Cost yourself (₽)	Notes
Partial replacement	2 500–4 000	1 200–1 800	Includes oil, filter, gasket and labor.
Complete replacement (with flushing)	5 000–8 000	2 500–3 500	Requires 8–10 liters of oil and special equipment.
Emergency replacement (with diagnostics)	7 000–12 000	3 000–5 000	Includes solenoid testing and adaptation.

Replacing it yourself is cheaper, but requires time and care. If you have never worked with an automatic transmission, it is better to contact a service center - mistakes when changing the oil can result in repairs costing 30-50 thousand rubles.

Where to buy consumables:

• 🛒 Original spare parts - from official dealers Nissan or in trusted online stores (for example, Exist.ru, Autodoc).
• 🛒 Analogues - in stores like Liqui Moly, Castrol or Mobil. Beware of fakes!

FAQ: Frequently asked questions about changing the oil in an Almera Classic automatic transmission

Is it possible to fill in oil from another manufacturer if there is no original one?

Yes, but only if it meets specification Nissan Matic D. Suitable analogues: Idemitsu Type-J, Mobil ATF 3309 or Castrol Transmax J. Never use universal oils such as Dexron — they are not compatible with the clutches of this box.

How much oil is needed for a complete change?

For a complete replacement with flushing you will need 7–8 liters. If flushing is not performed, 4–5 liters are sufficient (using the multiple drain/fill method). The exact volume depends on how much oil remains in the torque converter.

Do I need to change the filter every oil change?

Yes, It is recommended to change the filter every time, especially with a complete replacement. It traps metal shavings and wear products that clog oil passages over time. An exception is if the filter is still in good condition (for example, when partially replaced after 30 thousand km).

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

The consequences depend on the mileage:

• 🔸 100–150 thousand km: jerks when switching, deterioration in dynamics.
• 🔸 150–200 thousand km: wear of friction clutches, slipping of gears.
• 🔸 200+ thousand km: destruction of the planetary mechanism, jamming of the box.

In critical cases, automatic transmission repairs cost 50–100 thousand rubles, so prevention is cheaper.

Is it possible to mix old and new oil?

Mixing is permissible only in two cases:

1. If the old oil has not yet lost its properties (light color, no burning smell).
2. If the new oil is of the same type and manufacturer.

In other cases it is recommended complete replacement, since mixing different additives can cause a chemical reaction and the formation of sediment.
