Changing the oil in a manual transmission <em>Nissan Almera Classic</em>: a complete guide with photos and tips

Manual transmission Nissan Almera Classic (body B10, 2006–2012) is famous for its reliability, but only subject to timely maintenance. One of the key procedures is changing transmission oil - an operation that many car owners prefer to do on their own. Unlike automatic transmissions, where the oil is changed every 60–80 thousand km, in manual transmissions the interval can reach 100–120 thousand km, but this does not mean that the procedure can be ignored. Over time, the oil loses its lubricating properties, accumulates metal shavings and oxides, which leads to accelerated wear of synchronizers and bearings.

In this article you will find step by step instructions for changing oil in manual transmission Almera Classic taking into account the nuances of the model, recommendations for choosing oil (including original articles and analogues), as well as list of errors, which beginners often make. We'll look at what tools you'll need, how to check the oil level without a dipstick, and why you can't use motor oil instead of transmission oil. If you have never done this kind of work, don’t worry: the process is simpler than it seems, and with the right approach it will take no more than 1–1.5 hours.

When to change manual transmission oil Nissan Almera Classic?

Official regulations Nissan for model Almera Classic (B10) prescribes first oil change in a manual transmission at a mileage of 90–100 thousand km, and subsequent ones - every 60–80 thousand km. However, these figures are relevant for “ideal” operating conditions: moderate climate, absence of sudden temperature changes and aggressive driving. In reality, the interval should be shortened:

• 🏙️ City mode with frequent traffic jams and gear changes - replace the oil with 70–80 thousand km.
• ❄️ Operation at temperatures below −20°C or above +35°C - reduce the interval to 50–60 thousand km.
• 🚗 Aggressive driving style (sharp starts, towing a trailer) - check the condition of the oil every 40 thousand km.
• 🔧 After repairing the gearbox (replacing the clutch, seals, bearings) - change the oil necessarily, regardless of mileage.

How do you know when it's time to change the oil? Pay attention to the following symptoms:

• 🔊 Crunching or grinding noise when changing gears (especially when cold).
• 🕒 Slow response of the box to switching (the lever “sticks”).
• 🛢️ Darkening of the oil (when checking through the inspection hole).
• 💨 Burning smell from transmission fluid.

⚠️ Attention: If found in oil metal particles (shavings, sawdust) - this is a sign of wear on the gears or bearings. In this case, changing the oil will only temporarily delay the repair of the gearbox.

What kind of oil to fill in manual transmission Nissan Almera Classic?

For Almera Classic (B10) with manual transmission JH3 (5-speed) or JH1 (4-speed) Nissan recommends gear oils with specifications API GL-4 and viscosity 75W-80 or 75W-90. Important: do not use oils rated GL-5 - they contain aggressive additives that can damage synchronizers made of non-ferrous metals.

Original oil from Nissan has an article number KE908-99932 (1 l) or KE908-99931 (4 l), but it can be replaced with high-quality analogues:

Brand	Article	Viscosity	Volume, l	Note
Nissan Original	KE908-99932	75W-80	1	Official recommendation
Mobil Mobilube 1 SHC	152620	75W-90	1	Synthetic, high lubricating properties
Castrol Syntrans Transaxle	157F6F	75W-90	1	Suitable for harsh conditions
Liqui Moly Hochleistungs-Getriebeoil	1057	75W-90	1	Improves the performance of synchronizers
Motul Gear 300	105784	75W-90	1	For a sporty riding style

Oil volume in manual transmission Almera Classic amounts to 2.8–3.0 liters, but for a complete replacement you will need 3.2–3.5 l (some of the oil will remain in the box). Don't skimp on quality: cheap oils can lead to jamming of synchronizers or seal leaks.

⚠️ Attention: Some service stations offer to fill in manual transmission Almera Classic oil ATF (for automatic transmission) or engine oil. This blunder — such liquids do not provide the necessary protection for the gears and can cause gearbox failure.

Tools and materials for oil change

To change the oil in a manual transmission yourself Nissan Almera Classic you will need the following set of tools and consumables:

• 🔧 24mm wrench (for drain plug).
• 🔧 10 mm wrench (for crankcase protection, if any).
• 🛢️ Gear oil (3.5 l, see section above).
• 🧤 Gloves and rags (oil is toxic!).
• 🔧 Socket wrench with extension (to access the filler hole).
• 📏 Oil syringe (with flexible hose) or funnel with tube.
• 🔧 Torque wrench (optional, for precise tightening of plugs).
• 🧲 Magnet (to collect metal shavings from the drain plug).
• 🚗 Jack or inspection hole (required!).
• 🛢️ Drain container (volume of at least 4 l).

If you plan to wash the box, additionally prepare 1–1.5 l of flushing oil (For example, Liqui Moly Getriebe-Reiniger, article 1998). However, flushing is only required if heavy pollution or changing the type of oil (for example, from mineral to synthetic).

Step-by-step instructions for changing the oil

The process of changing the oil in a manual transmission Nissan Almera Classic consists of three stages: draining the old oil, washing (if necessary) and filling with new oil. Let's look at each step in detail.

1. Drain old oil

Before draining the oil be sure to warm up the box — for this it is enough to drive 5–10 km. Warm oil is fluid and will drain faster, taking with it more contaminants.

1. Place the car on inspection hole or raise the front part on a jack (be sure to secure it with stops!).
2. Remove crankcase protection (if there is one) - usually secured with 4-6 10 mm bolts.
3. Find drain plug on the box (it is located at the bottom of the manual transmission, closer to the rear of the engine).
4. Place the drain container and unscrew the plug with a 24 mm wrench. Be careful - the oil may be hot!
5. Wait until the oil is completely drained (10–15 minutes). If the oil is dark with metal particles, the box requires diagnostics.

After draining, inspect drain plug: metal shavings often accumulate on its inside. Clean the plug and magnet (if there is one) with a rag.

2. Washing the box (optional)

Flushing is only necessary in three cases:

• 🔄 You are switching from mineral oil to synthetic oil.
• 🧹 When drained, the oil was extremely dirty (black, with flakes).
• 🔧 The box was being repaired and foreign particles could have gotten into it.

For washing:

1. Screw in the drain plug.
2. Fill through the filler hole 1–1.5 l of flushing oil.
3. Start the engine and let it idle for 5-10 minutes, alternating gears (with the clutch depressed!).
4. Drain the flushing oil and start filling in new oil.

⚠️ Attention: Do not use for rinsing kerosene, diesel fuel or motor oil - this can damage the seals and synchronizers.

3. Filling with new oil

Filler hole in manual transmission Almera Classic located on the side of the box, closer to the front of the car. It may be difficult to access, so it is recommended to use syringe with flexible hose or a funnel with an extension.

1. Make sure that the drain plug is tightened (tightening torque is 30–40 Nm).
2. Remove filler plug (24 mm wrench).
3. Start adding oil. When it starts to flow out of the filler hole, the box is full.
4. Tighten the filler plug (tightening torque - 30–40 Nm).
5. Wipe the box with a rag, removing any traces of oil.

After replacement, check the operation of the box: change gears with the engine off (they should turn on smoothly, without crunching). Then drive 5–10 km and inspect the box for leaks.

Common mistakes when changing oil in a manual transmission

Even experienced car owners sometimes make mistakes that can lead to box breakage or oil leaks. Here are the most common of them:

• 🔧 Retightening the drain or filler plug - this leads to thread breakage or cracks in the box body. Use a torque wrench (torque - 30–40 Nm).
• 🛢️ Insufficient or excessive oil level - in the first case, the box will be “dry”, in the second, the oil will squeeze out through the seals.
• 🧴 Mixing different types of oils (for example, synthetics and mineral water) - this causes chemical reactions and the formation of sediment.
• 🔥 Changing the oil with a cold box - in this case, only part of the oil will drain, and the dirt will remain inside.
• 🚗 Ignoring metal shavings - if there is a lot of it, the box requires diagnostics, and not just an oil change.

Another common mistake is using sealant on plug threads. In manual transmission Almera Classic traffic jams have copper o-rings, which deform when tightened, ensuring tightness. The sealant is not needed here and can get inside the box.

What to do if after changing the oil it leaks from the box?

If after changing the oil you find a leak, the reasons may be as follows:

1. **The drain/fill plug is not tightened** - tighten it with the correct torque (30–40 Nm).

2. **O-ring is damaged** - replace it with a new one (part number 11026-01M02 for Nissan).

3. **Crack in the box body** - service diagnostics required.

4. **The drive oil seal is damaged** - it will have to be replaced (article number 38340-4M000).

If the leak is severe, do not operate the car - contact a service center.

How to check the oil level in a manual transmission without a dipstick?

In manual transmission Nissan Almera Classic no dipstick to check the oil level. Instead it is used control (filler) holelocated on the side wall of the box. Here's how to check the level correctly:

1. Place the car on flat surface (no slope!).
2. Unscrew filler plug 24 mm wrench.
3. The normal level is when the oil reaches the edge of the hole (may leak a little).
4. If the oil is not visible, it needs to be added (use syringe or funnel).
5. If the oil flows out in a stream, the level is excessive, some of it needs to be drained.

It is better to check on a warm box (after a trip of 5–10 km), since the oil expands when heated. If the box is cold, the level may be too low.

Cost of oil change at service vs. on your own

Manual transmission oil change price Nissan Almera Classic in service depends on the region and level of the service station. On average, expenses add up like this:

Service/Material	On your own	Service (economy)	Service (premium)

Flushing oil (1 l)	500–800 ₽	800–1 200 ₽	1 200–1 500 ₽
Plug O-rings	100–200 ₽	Included in work	Included in work
Work (oil change)	0 ₽	1 000–1 500 ₽	1 500–2 500 ₽
Total	3 100–5 000 ₽	4 800–7 200 ₽	7 200–10 000 ₽

As can be seen from the table, DIY replacement costs 1.5–2 times less, even taking into account the purchase of tools (syringe, keys). However, if you are not confident in your abilities or you do not have an inspection hole, it is better to contact the service. The main thing is to choose proven service stations with a guarantee on their work.

Frequently asked questions (FAQ)

Is it possible to fill it in a manual transmission? Almera Classic 80W-90 oil instead of 75W-80?

Yes, you can, but only if you operate the car in hot climate (temperature above +35°C). Oil 80W-90 more viscous and less suitable for cold starts. In most regions of Russia, it remains optimal 75W-80 or 75W-90.

What happens if you don’t change the oil in your manual transmission?

Over time, the oil loses its lubricating properties and accumulates metal shavings and oxides. This leads to:

• Accelerated wear synchronizers (crunching noise when switching).
• Damage bearings shafts
• Difficulty shifting gears (especially when cold).
• In critical cases - box jamming.

Average manual transmission resource Almera Classic with regular oil changes - 250–300 thousand km. Without maintenance this figure drops to 150–200 thousand km.

Do I need to flush the transmission when changing the oil?

Flushing is only necessary in three cases:

1. You are switching from mineral oil to synthetic oil.
2. The drained oil was extremely dirty (black, with flakes).
3. The box was being repaired and foreign particles could have gotten into it.

In all other cases, flushing is not necessary and can even be harmful if low-quality flushing fluid is used.

What kind of oil is poured into the manual transmission? Almera Classic from the factory?

From factory to manual transmission Nissan Almera Classic (B10) original oil is filled Nissan MT Fluid with viscosity 75W-80 (article KE908-99932). This semi-synthetic oil with a package of additives optimized for boxes Nissan.

Is it possible to mix different gear oils?

Mix oils not recommended, especially if they are of different types (mineral + synthetic) or from different manufacturers. As a last resort, you can add oil of the same brand and viscosity, but It is better to do a complete replacement as soon as possible.

The exception is oils from the same manufacturer with the same specifications (for example, Mobil 75W-90 And Castrol 75W-90 with permission GL-4), but even in this case mixing should be a temporary measure.
