Changing the oil in automatic transmission Nissan Almera G15 - a procedure that many owners put off until the last minute, considering it complicated or unnecessary. However, ignoring this maintenance may result in expensive automatic transmission repairs already after 100–150 thousand kilometers. Unlike motor oil, transmission fluid is Jatco JF414E (installed on Almera G15) degrades more slowly, but its properties deteriorate with every thousand kilometers: viscosity decreases, friction wear products accumulate, filters become clogged.
In the official manuals Nissan It is often stated that automatic transmission oil is filled “for its entire service life,” but this is a marketing ploy. In practice a complete oil change is required every 60–80 thousand km, and partial (update) - once every 30-40 thousand km, especially if the car is operated in urban mode with frequent traffic jams. In this article we will look at how to replace it yourself, what oil to choose, what tools you will need and what to pay attention to so as not to damage the box.
What kind of oil to fill in the automatic transmission of Nissan Almera G15
Box JF414E, installed on Almera G15 (1.5 and 1.6 l), demanding on the quality of transmission fluid. Using the wrong oil may cause clutch slippage, jerking when changing gears or even failure of the valve body. Official recommendations Nissan:
- 🔹 Original oil: Nissan Matic Fluid S (article
KE908-99932) is the best choice, but expensive (about 1,200–1,500 ₽/liter). - 🔹 Analogues: Idemitsu ATF Type-S, Ravenol ATF JWS 3309, Mobil ATF 3309 — fully compatible according to specifications.
- 🔹 Volume: for a complete replacement you will need 7–8 liters (in the box there are ~6.5 liters, but some remains in the torque converter).
- 🔹 Partial replacement: 3-4 liters is enough, but the procedure will have to be repeated 2-3 times with an interval of 500-1,000 km.
Important: Do not mix oils from different manufacturers, even if they meet the specification JWS 3309. If you do not know what was previously filled, it is better to carry out a complete replacement with flushing. Also avoid generic ATF fluids (e.g. Dexron III or Dexron VI) - they are not suitable for JF414E.
⚠️ Attention: Oils with markings ATF+4 (for example, for Chrysler) are strictly incompatible with Almera G15. Their use will lead to destruction of rubber seals and loss of pressure in the system.

Tools and materials for oil change
To change the automatic transmission oil yourself Nissan Almera G15 you will need:
| Name | Quantity | Notes |
|---|---|---|
| Gear oil (see section above) | 7–8 liters | For a complete replacement |
| Automatic transmission filter | 1 piece | Original article: 31726-31X00 or analogues JS Asakashi, Febi |
| Pan gasket | 1 piece | Article: 31397-31X02. You can use sealant Loctite 574 instead of a gasket |
| Square key 8 mm | 1 piece | To unscrew the drain plug |
| 10 mm head | 1 piece | For pallet bolts |
| Funnel with extension | 1 piece | To fill oil through the dipstick |
Additionally you may find it useful:
- 🔧 Torque wrench (tightening torque of the pallet bolts is 8–10 Nm).
- 🧴 Carburetor Cleaner or kerosene for washing the pan.
- 🧤 Nitrile gloves — automatic transmission oil is toxic.
- 📦 Drain container volume of at least 5 liters.
If you plan complete replacement with flushing, you will additionally need:
- 🔄 Oil change machine (can be rented at a car service station).
- 🔌 Adapter for connecting to the automatic transmission cooling radiator.
Before changing the oil, warm up the box to operating temperature (drive 10–15 km). This will reduce the viscosity of the oil and allow the maximum amount of waste to be drained.
Step-by-step instructions: partial oil change
Partial replacement is suitable if the oil is in the automatic transmission Almera G15 not heavily soiled (light brown color, no burnt smell). The procedure takes about 1–1.5 hours.
Warm up the automatic transmission (drive 10–15 km)|Place the car on a flat surface (a hole or a lift)|Stop the engine and apply the parking brake|Prepare a drain container and tools-->
Step 1. Drain the old oil
- Place a container under the drain plug (it is located on the automatic transmission pan).
- Unscrew the plug with an 8 mm square wrench. Be careful - the oil will be hot!
- Wait until it drains completely (usually ~3–3.5 liters flow out).
Step 2: Replacing the filter and cleaning the pan
- Unscrew the pan bolts (14 pieces) with a 10 mm socket. Remove the pan - ~0.5 liters of oil will remain in it.
- Clean the pan and magnets from metal shavings (use carburetor cleaner).
- Replace the automatic transmission filter (it is secured with 3 bolts).
- Install a new gasket or apply sealant to the edge of the pan.
Step 3. Filling with new oil
- Place the pan in place and tighten the bolts crosswise (torque 8–10 Nm).
- Insert a funnel into the dipstick hole and fill in new oil (volume = drained + 100–200 ml).
- Start the engine, warm up the box (switch all selector modes with a delay of 5 seconds).
- Check the oil level with a dipstick - it should be between the marks
HOT.
⚠️ Attention: If after changing the oil quickly darkens (after 500–1,000 km), this is a sign of severe wear of the clutches. In this case it is required complete replacement with flushing or automatic transmission diagnostics.
Complete automatic transmission oil change: nuances and risks
Complete oil change Almera G15 involves replacing the old fluid with a new one using a special device connected to the automatic transmission cooling system. This method allows you to update 90–95% oil, but has its pitfalls:
- 🔄 Flushing the torque converter: with a complete replacement, it is also cleaned, where the most dirt accumulates.
- ⚠️ Risk of clogged solenoids: if there is a lot of deposits in the box, they can clog the valve body channels.
- 💧 Level control: after the procedure, you need to accurately set the oil level (overfilling or underfilling is dangerous!).
When is a complete replacement needed?
- 🔴 Black oil with a burnt smell.
- 🔴 There are a lot of metal shavings in the pallet.
- 🔴 The transmission “kicks”, slips, or takes a long time to engage gears.
- 🔴 Mileage more than 100 thousand km without oil change.
It is better to entrust the procedure to a service, but if you decide to do it yourself, follow the algorithm:
- Drain the oil through the plug (as with a partial replacement).
- Disconnect the hoses from the automatic transmission cooling radiator and connect the device.
- Start the engine and turn on the device - it will pump new oil, displacing the old one.
- Control the color of the oil at the exit: when it becomes light, the procedure can be completed.
- Remove the device, connect the hoses back, add oil to the level and check the operation of the box.
What happens if you pour oil into an automatic transmission?
Overflowing oil into automatic transmission Almera G15 leads to foaming of the liquid, loss of pressure and accelerated wear of the pump wheel. Symptoms: jerking when switching, noise from the transmission, leaks through the breather. If you overfilled, drain the excess through the control hole (plug on the pan).
Common mistakes when changing automatic transmission oil
Even experienced car owners make mistakes that can result in automatic transmission repairs. Here are the most common:
- 🛑 Using the wrong oil (For example, Dexron VI instead of JWS 3309) - leads to destruction of rubber seals.
- 🛑 Failure to comply with the tightening torque of the pallet bolts — over-tightening deforms the gasket, under-tightening causes leaks.
- 🛑 Ignoring filter replacement - the old filter does not retain wear products, and they circulate throughout the system.
- 🛑 Incorrect oil level - both overfilling and underfilling are equally harmful.
- 🛑 Changing the oil with a cold box - in this case, only part of the waste is drained, but the dirt remains.
How to avoid mistakes?
- ✅ Always check oil compatibility according to catalogs Nissan or consult your dealer.
- ✅ Use a torque wrench to tighten the bolts.
- ✅ After replacement, be sure to warm up the box and check the level with the engine running.
- ✅ If you doubt your abilities, contact a service with good automatic transmission reviews.
The most common cause of automatic transmission breakdowns after an oil change is the use of low-quality non-original filters. Saving 500–800 rubles on a filter can result in repairs costing 50–100 thousand rubles.
Signs that the automatic transmission oil needs to be changed urgently
If you did not follow the replacement regulations, pay attention to the following symptoms:
| Sign | Possible reason | What to do |
|---|---|---|
| Jerks when shifting gears | Contaminated oil, worn clutches | Complete oil change + diagnostics |
| Burnt smell from oil | Automatic transmission overheating, clutch slipping | Complete replacement + radiator check |
| Dark or black oil color | Severe wear of parts, decomposition products | Complete replacement with flushing |
| Noise or hum in the box | Lack of oil, bearing wear | Checking the level + topping up/replacing |
| Oil leaking from under the pan | Worn gasket, crack in pan | Replacing the gasket or pan |
If you notice at least one of these signs, don't put off changing the oil. In advanced cases, it may be necessary to repair the valve body or replace friction discs, which will cost 30–50 thousand rubles.
