Removing the gearbox on a Nissan Note: instructions with nuances for manual transmission and CVT

Removing the gearbox Nissan Note - a task that owners face when making major repairs, replacing a clutch or eliminating oil leaks. The process requires accuracy, special tools and knowledge of key points, especially when it comes to models with CVT JR15E or manual transmission RS5F92A. In this article, we will analyze the step-by-step procedure, typical mistakes and give practical advice that will save you time and nerves.

It is important to understand that the design Nissan Note (especially generations E11 And E12) has its own characteristics: a cramped engine compartment, an inconvenient location of some fasteners and the sensitivity of the variator electronics to mechanical influences. If you have never done such work, it is better to enlist the help of an experienced mechanic or at least carefully study service manual for your modification. We will focus on universal stages that are relevant for most versions.

Preparation for dismantling: tools and conditions

Before you begin removing the box, make sure you have everything you need. The work will require not only a standard set of keys, but also specialized tools. Here is the minimum list:

• 🔧 A set of sockets and ratchet wrenches (necessarily with extensions and a cardan for hard-to-reach bolts).
• 🔨 Jack and reliable supports (or a lift is ideal).
• 🔩 Puller for axle shafts (if you plan to remove them).
• 🔧 Torque wrench (for precise tightening of fasteners during reassembly).
• 🧰 Crankcase sealant (for example, Loctite 574 or equivalent).
• 📦 Containers for draining oil (separately for the gearbox and engine, if necessary).
• 🔋 Multimeter (for checking the variator sensors after dismantling).

Pay special attention to your workplace. Nissan Note - a compact car, and for easy access to the box you will need:

• 🚗 Flat area with hard surface (asphalt or concrete).
• 💡 Good lighting (it is better to use a portable 12V lamp).
• 🧲 Magnetic tray for fasteners (so as not to lose small bolts and washers).

⚠️ Attention: If you are working with a variator, never drop or hit the box when dismantling - this may damage the chain or cone pulleys, which will lead to irreversible damage. CVTs Nissan extremely sensitive to mechanical stress!

Also prepare in advance service documentation for your model. For example, for Nissan Note E12 with a variator, a diagram of the location of sensors and connectors will be useful so as not to damage them when disconnected. If there is no documentation, download it from sites like Nicoclub or Service Manuals.

Draining the oil and disconnecting the battery: why is this critical

The first practical step is draining the oil from the box. Many people skip this step, thinking that they can do without it, but this is a grave mistake. Oil in the gearbox (especially in the variator) not only facilitates dismantling, but also prevents splashing when removing the pan. For Nissan Note the procedure looks like this:

1. Start the car and let it run for 2-3 minutes to warm up the oil (this will speed up draining).
2. Raise the car on a jack or lift and secure it.
3. Place a container with a volume of at least 5 liters under the drain hole of the box.
4. Unscrew the drain plug (on the variator it is often combined with the dipstick).
5. Wait until the oil is completely drained (this may take 15–20 minutes).

After draining the oil, be sure to turn off battery. This is not just a precaution, but Nissan Note The electronics of the box (especially the variator) remain energized even when the ignition is turned off. Disconnect the negative terminal and insulate it to avoid short circuit when working with sensors.

⚠️ Attention: If you are working with a variator JR15E, after draining the oil do not tilt the box more than 10° - this can lead to displacement of internal parts and failure of the pulleys.

It is also recommended at this stage to remove air filter and pipes that interfere with access to the top bolts of the box. On models with engine HR15DE this is especially true - the space above the checkpoint is extremely limited.

Removing drives and axle shafts: nuances for front-wheel drive models

Removing drives is one of the most time-consuming steps. On Nissan Note with front-wheel drive, the axle shafts are attached to the box through internal CV joints, and their dismantling requires care. Here is a step-by-step algorithm:

1. Remove the wheels and brake discs (if they interfere with access).
2. Unscrew the nuts securing the axle shafts to the hubs (you will need a 32 or 36 head, depending on the year of manufacture).
3. Use a puller to press the axle shafts out of the hubs. Do not hit the shaft with a hammer - this can damage the CV joint boots.
4. Disconnect the axle shafts from the box. On the variator they are fixed with retaining rings, which can “stick”. Use special lubricant (for example, WD-40 Specialist) and carefully loosen the shaft.

On models with Manual transmission RS5F92A The left drive is shorter than the right drive, so removal is usually easier. But on the variator, both drives are the same length, but their dismantling is complicated by the presence speed sensor, which is attached to the box housing. Be careful - it can be easily damaged!

Gearbox type	Features of removing drives	Possible problems
Mechanical (RS5F92A)	The left axle shaft is shorter than the right one. Retaining rings may become stuck.	Damage to CV joint boots during pressing out.
CVT (JR15E)	Both drives are the same length. The speed sensor is attached to the crankcase.	Risk of damage to the sensor or connectors during removal.
Automatic (RE0F10A)	The drives are removed in the same way as a manual transmission, but the torque converter must be disconnected.	Oil leakage from the torque converter due to careless removal.

If the axle shafts do not budge, do not apply excessive force. Better use penetrating lubricant and give it time to work (10-15 minutes). Also check whether it interferes with dismantling jet thrust or anti-roll bar - sometimes you have to temporarily remove them.

Disconnecting the box from the engine: bolts, connectors and cushions

Now we move on to the most important stage - disconnecting the gearbox and engine. On Nissan Note they connect through clutch bell (for manual transmission) or torque converter (on CVT/automatic transmission). Your task is to carefully unscrew all the fasteners and disconnect the connectors.

Start with the top bellhousing bolts. There are usually 4–6 of them, and they can be hidden under a thermal screen or pipes. Use extension cord with cardanto get to them. The lower bolts are unscrewed after the box is partially lowered.

Next, disconnect:

• 🔌 Crankshaft position sensor connector (if it goes through the box).
• 🔌 Connectors for solenoids (on a variator) or reverse sensor (on a manual transmission).
• 🔧 Fastening the clutch cable (on the mechanics) or the hydraulic line (on the variator).
• 🔧 Box pillows (usually 2-3 pieces, one of them can be hidden under the thermostat).

On a variator JR15E pay special attention hydraulic lines. They should not be bent or twisted as this may cause blockage or rupture. If the lines are heavily contaminated, it is better to replace them with new ones.

⚠️ Attention: On models with a variator, after disconnecting the solenoid connectors you can't turn on the ignition - this can trigger an error in the transmission control unit, which will then have to be reset via Nissan Consult.

When all the fasteners are unscrewed, the box must be carefully lowered. To do this use transmission jack or hang the gearbox on cables. Do not try to hold it by hand - the weight of the box (especially the variator) can exceed 50 kg!

What to do if the bell bolt is stuck?

If the bolt does not come off, try the following methods:

1. Heat it with a hair dryer (do not overheat - 100–150°C is enough).

2. Use an impact driver or air impact wrench.

3. Apply lubricant PB Blaster or Liquid Wrench and let it soak in for 15-20 minutes.

4. As a last resort, carefully cut off the bolt with a grinder, but be careful not to damage the threads in the engine block!

Removing the box: safety precautions and common mistakes

When the box is separated from the engine and hanging on a jack or cables, all that remains is to carefully remove it from under the car. At this stage, many make critical mistakes that lead to breakdowns. Here's what to remember:

• 🚫 Do not pull the box by the input shaft - this may damage the bearings or splines.
• 🚫 Don't drop the gearbox — even from a small height, a fall can deform the crankcase.
• 🚫 Don't forget about weight — the variator weighs more than the mechanics, so use reliable fastenings.

On Nissan Note The box is pulled down and slightly back (towards the trunk). If it gets stuck, check:

• 🔧 Doesn't it interfere? starter (sometimes it needs to be removed in advance).
• 🔧 Did you forget to unscrew bottom pillow boxes.
• 🔧 Is the box clinging to parking brake cable.

After removing the box, inspect it for oil leaks, cracks in the crankcase or connector damage. If you plan to disassemble the gearbox further (for example, to replace the clutch or variator belt), do it on a clean workbench, having previously marked all the parts.

For CVT JR15E After removal, be sure to check:

• 🔍 Condition chains (there should be no stretching or chipping).
• 🔍 Backlash cone pulleys (permissible play - no more than 0.5 mm).
• 🔍 Cleanliness oil filter (if it is clogged, it needs to be replaced).

Reassembly: What you need to know

Putting the box back is a process no less important than dismantling it. It is important to observe here bolt tightening sequence, tightening torques and connect all connectors correctly. Start with preparation:

1. Clean the mating surfaces of the engine block and gearbox from old sealant and oil.
2. Apply new sealant to the gearbox housing (in a thin layer, without excess).
3. Make sure clutch disc (for manual transmission) or torque converter (on the variator) are installed correctly.

When installing the box, make sure that:

• 🔹 The primary shaft entered the clutch without distortions.
• 🔹 All connectors have been connected until the bolts are fully tightened.
• 🔹 The box cushions were tightened to the correct torque (usually 40–60 Nm).

After installing the box:

1. Tighten the bellhousing bolts to cruciform sequence (tightening torque: 50–70 Nm).
2. Connect the drives and tighten the hub nuts (torque - 180–220 Nm).
3. Fill the gearbox with new oil (for CVT JR15E use only Nissan CVT Fluid NS-3).
4. Swipe variator adaptation (if applicable) via diagnostic scanner.

⚠️ Attention: After changing the oil in the variator, avoid sudden acceleration and towing for the first 500 km - this is necessary to evenly distribute the new fluid throughout the system.

Checking after installation: what you should be wary of

After assembly, be sure to take a test drive to ensure the box is in good working order. Here's what to look for:

• 🚗 Extraneous noise (grinding, humming) when driving or in neutral.
• 🚗 Vibrations at speeds of 60–80 km/h (may indicate shaft misalignment).
• 🚗 Jerking or slipping (on a variator this is a sign of a faulty circuit or solenoids).
• 🚗 Oil leaks from under the crankcase or oil seals.

If you notice any of these symptoms, stop immediately and check:

• 🔧 Oil level in the gearbox (on a variator it is checked on a warm box!).
• 🔧 Tightening all fastenings (especially pillows and bells).
• 🔧 Connecting sensor connectors (on a variator, the error may not be displayed on the device, but the box will not work correctly).

For CVT JR15E After repair it is also recommended to reset adaptive settings through diagnostic equipment. This will help the box “get used” to the new working conditions.

FAQ: Frequently asked questions about removing the transmission on a Nissan Note

Is it possible to remove the box on a Nissan Note without a lift?

Theoretically yes, but it is extremely inconvenient. Without a lift, you will need a reliable jack, supports and a helper to hold the box during removal. The risk of dropping the gearbox or damaging the connectors is much higher. If there is no alternative, use transmission trolley or homemade cable fastenings.

What kind of oil should I pour into the variator after removal?

For CVTs JR15E (installed on Nissan Note E12) officially recommended Nissan CVT Fluid NS-3. Use of other oils (eg NS-2 or universal ATF) will lead to accelerated wear of the chain and pulleys. Refill volume is 7.5–8.2 liters (depending on the model).

Do I need to change the clutch when removing the manual transmission?

Not necessary, but it is recommended to inspect its condition. If on driven disk there are cracks, chips or wear of the friction linings of more than 0.3 mm, it is better to replace it. Also check release bearing - it should rotate without play or noise. Cost of a new clutch kit for Nissan Note - about 8–12 thousand rubles (for 2026).

How to check the variator sensors after removal?

To diagnose sensors (speed, oil temperature, pulley position), you will need a multimeter or scanner Nissan Consult. Check:

• Sensor resistance (must correspond to the values ​​from the manual).
• No breaks in the wiring.
• The signals on the control unit connector are correct (5V or 12V power supply depending on the sensor).

If the sensor is faulty, replace it with a new one (original sensors for JR15E are indicated by articles 31396-JR15A or 31396-JR15B).

How long does it take to remove a box in a garage?

Time depends on experience and type of checkpoint:

• Mechanical (RS5F92A): 4–6 hours (without disassembling the clutch).
• CVT (JR15E): 6–8 hours (due to the large number of connectors and hydraulic lines).

If this is your first time doing this kind of work, reserve yourself a whole day - haste is unacceptable here.
