Automatic transmission Nissan Almera Classic (also known as Nissan Sunny B10 or N16 in some markets) requires regular maintenance to avoid costly repairs. Changing the oil in an automatic transmission is one of the key procedures that many owners put off until the first symptoms of a malfunction appear: jerking, delays when switching, or extraneous noise. However routine oil change - This is not just a recommendation, but a necessity to extend the life of the transmission.

In this article we will look at all stages of changing the oil in an Almera Classic automatic transmission: from choosing the right liquid to step-by-step instructions taking into account the features of the model. You'll learn what tools you'll need, how to check the oil level, and why partial changes aren't always effective. And also - what errors lead to torque converter failure within 20–30 thousand km after improper maintenance.

When to change the oil in a Nissan Almera Classic automatic transmission: regulations and signs of wear

Official regulations Nissan for Almera Classic (including versions with automatic transmission RE4F03A or RE4F04B) provides for oil changes every 60–90 thousand km. However, these figures are relevant for “ideal” operating conditions: moderate climate, absence of traffic jams and towing. In the realities of Russian roads and city traffic, the interval should be reduced to 40–50 thousand km.

If you are not sure when the oil was last changed, check signs of wear:

  • 🔴 Jerks or jolts when changing gears (especially from 1st to 2nd).
  • 🔴 Delays when moving from “D” to “R” or vice versa.
  • 🔴 Extraneous sounds: hum, grinding or rustling noise in the automatic transmission area.
  • 🔴 Burning smell from oil (checked with a dipstick).
  • 🔴 Dark oil color (should be reddish, not black or brown).

If any of these symptoms appear, an oil change is already necessary. Ignoring problems leads to wear of the clutches, clogging of the valve body and, ultimately, to overhaul of automatic transmission, which will cost 50–100 thousand rubles.

📊 How often do you change the automatic transmission oil?
  • Every 40–50 thousand km
  • Only according to regulations (60–90 thousand km)
  • When problems arise
  • Never changed

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

For Almera Classic with automatic transmission RE4F03A/RE4F04B Nissan recommends original oil Nissan Matic Fluid D (article KE908-99931). This is a synthetic fluid designed specifically for 4-speed automatic transmissions. Nissan And Renault. However, there are worthy analogues on the market that are not inferior in quality, but are cheaper.

Before buying oil, check its authenticity: original Nissan Matic Fluid D has a holographic sticker on the canister and a clear barcode. Counterfeits are often sold in cans with blurred labels.

Tools and materials for changing automatic transmission oil

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

  • 🔧 Set of sockets and keys (especially on “10”, “14” and “17”).
  • 🔧 Socket wrench "24" for the drain plug (in some versions - a hexagon at “5”).
  • 🔧 Funnel with long spout (for filling oil through the dipstick).
  • 🔧 Drain container (volume of at least 5 liters).
  • 🔧 New automatic transmission oil filter (article 31726-31X00 or 31726-31X01).
  • 🔧 Pan gasket (article 31397-31X00 or equivalent Victor Reinz).
  • 🔧 Rags and gloves (oil is toxic!).
  • 🔧 Torque wrench (for tightening bolts with the correct torque).

If you plan complete replacement with flushing, you will additionally need:

  • 🔧 Oil change machine (can be rented at a car service station).
  • 🔧 Flushing fluid (For example, Liqui Moly ATF Reiniger).
  • 🔧 New O-rings for the valve body (if you remove it).

⚠️ Attention: Do not use Karcher or other pressure cleaners for cleaning the automatic transmission pan. A jet of water can damage valve body solenoids or wash away factory lubricant from parts.

Warm up the car (drive 10–15 km)

Place the car on a flat surface (pit/overpass)

Prepare tools and oil

Loosen the drain plug (do not unscrew completely!)

Disconnect the negative terminal of the battery (for safety) -->

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

Partial replacement is suitable if the oil is not very dirty and you monitor its condition. This method allows you to update 30–40% liquid without disassembling the box.

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 → 2 → L), holding each for 3–5 seconds. This will help the oil warm up evenly and drain better.

Step 2. Drain the old oil

  1. Stop the engine and place a container under the drain hole.
  2. Unscrew the drain plug (24mm wrench or hexagon). Be careful — the oil is hot!
  3. Wait until it drains completely (about 3-4 liters).

Step 3: Replace the filter (optional)

If you decide to change the filter, do it now:

  1. Remove the automatic transmission pan (unscrew the bolts around the perimeter).
  2. Carefully remove the old filter and install the new one.
  3. Clean the tray of metal shavings and dirt (use a magnet to collect particles).
  4. Install a new gasket and tighten the pan to a torque 8–10 Nm.

Step 4. Filling with new oil

Use a funnel to pour oil through the dipstick. Fill in the same amount as drained (usually 3–3.5 liters). Then:

  1. Start the engine and go through all selector modes again.
  2. Check the oil level with a dipstick (should be between MIN And MAX in the zone HOT).
  3. Top up if necessary.

⚠️ Attention: After a partial change, the oil in the automatic transmission will mix with the old one, so repeat the procedure after 500–1000 kmto achieve maximum fluid renewal.

💡

A partial oil change in an automatic transmission is a temporary solution. To completely update the fluid, 2-3 such procedures are required at intervals of 1,000 km.

Complete automatic transmission oil change: when is it needed and how to do it

A complete oil change is recommended if:

  • 🔴 The oil is black or has a burning smell.
  • 🔴 A lot of metal shavings were found in the pallet.
  • 🔴 Automatic transmission works with jerks or delays.
  • 🔴 The car was used in difficult conditions (towing, off-road).

There are two methods for a complete replacement:

  1. Hardware replacement (using a washing installation). It is connected to the automatic transmission radiator pipes, the old oil is replaced by new oil under pressure.
  2. Manual replacement (multiple drain-fill). A more labor-intensive but reliable method.

Instructions for manual complete replacement:

  1. Drain the oil (as in a partial change).
  2. Fill with new oil and drive 10–15 km.
  3. Drain the oil again and refill. Repeat the procedure 3-4 timesuntil the drained oil turns light.
  4. At the last stage, replace the filter and pan gasket.

⚠️ Attention: With complete replacement be sure to reset the automatic transmission adaptations. To do this:

  1. Disconnect the battery terminal for 10–15 minutes.
  2. Start the engine and let it idle for 5 minutes.
  3. Drive 20–30 km in gentle mode (without sudden acceleration).

This will help the electronic control unit “forget” the old settings and adapt to the new oil.

What happens if you don’t reset the adaptations after changing the oil?

Without resetting the adaptations, the automatic transmission ECU will continue to use old switching algorithms designed for worn oil. This may lead to:

- Jerking when changing gears.

- Delays in response to pressing the gas pedal.

- Increased wear of clutches due to incorrect pressure in the valve body.

Resetting adaptations takes 5 minutes, but prevents these problems.

Typical mistakes when changing the oil in an Almera Classic automatic transmission

Even experienced car owners make mistakes that reduce the life of the automatic transmission. Here are the most common:

  1. Using the wrong oil. For example, Dexron VI instead of Matic Fluid D. This leads to clutch slippage and overheating of the box.
  2. Underfilling or overfilling of oil. A low level causes oil starvation, a high level causes oil foam and disrupts the operation of the torque converter.
  3. Ignoring filter replacement. The old filter becomes clogged with wear products, and the new oil quickly becomes contaminated.
  4. Tightening the pan bolts tightly. This deforms the gasket and causes leakage.
  5. Automatic transmission flushing with Karcher. The jet of water damages the valve body electronics.
  6. No reset of adaptations after changing the oil (especially during a complete change).

Another critical error - oil change without warming up. Cold oil does not drain completely, and up to 30% of the old fluid with wear products remains in the box.

⚠️ Attention: If, after changing the oil, the automatic transmission begins to work worse (jerking, knocking), stop immediately and check the level. It may be the wrong type of oil or too little of it. Driving in this condition will quickly ruin the box.

The cost of changing the oil in an automatic transmission: yourself vs service

Automatic transmission oil change price Nissan Almera Classic depends on the method and region. Here are the approximate prices:

Service On your own (₽) Service (₽)
Partial change (3–4 liters of oil + filter) 2 500–3 500 3 000–5 000
Complete change (7–8 liters of oil + filter) 5 000–7 000 6 000–9 000
Hardware replacement (with flushing) — 7 000–10 000
Oil change + valve body cleaning 8 000–12 000 12 000–18 000

Replacing it yourself is more profitable, but requires time and care. If you are not confident in your skills, it is better to contact the service. This is especially true complete replacement with flushingwhere special tools are needed.

⚠️ Attention: Some services offer a “cheap” oil change without removing the pan. This means that the filter is not changed, but the new oil is mixed with the old one. This approach ineffective and can damage the automatic transmission.

Frequently asked questions (FAQ)

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

No, mix oils from different manufacturers or types (for example, Matic Fluid D And Dexron III) is absolutely not possible. This leads to changes in viscosity, foaming and accelerated wear of the clutches. If you need to add oil, use just the same brand, which is already filled.

How much oil should be poured into the automatic transmission during a complete replacement?

For Nissan Almera Classic with automatic transmission RE4F03A/RE4F04B the total volume of oil is 7.2–7.8 liters. However, with a complete replacement (especially manually), it can take up to 10–12 liters, since some of the oil remains in the torque converter and channels.

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

Flushing is only necessary in two cases:

  1. If the oil is heavily contaminated (black, with a burning smell).
  2. If you bought a used car and do not know the service history.

For rinsing use special liquids (For example, Liqui Moly ATF Reiniger), but not ordinary solvents! Washing with Karcher or gasoline prohibited.

What should you do if, after changing the oil, the automatic transmission starts to jerk?

Possible reasons:

  1. Incorrect oil level (check with dipstick).
  2. Unsuitable oil (for example, filled with Dexron instead of Matic Fluid D).
  3. Adaptations have not been reset (disconnect the battery for 10 minutes).
  4. The hydraulic unit is dirty (needs cleaning).

If the problem persists, contact the service for diagnostics.

Is it possible to drive Almera Classic with dirty automatic transmission oil?

Technically possible, but highly undesirable. Dirty oil:

  • Accelerates wear of clutches and bearings.
  • It clogs the valve body channels, causing shift delays.
  • Leads to overheating of the automatic transmission (risk of torque converter failure).

If the oil turns black or smells burning, replacement is required — further operation will lead to expensive repairs.
