Owners Nissan Note second generation (E12 body) often face the need to service the transmission, since the continuously variable CVT is a sensitive unit to the state of the working fluid. Many people mistakenly believe that the oil is filled for its entire service life, but operation on Russian roads requires regular monitoring and replacement.
Ignoring maintenance schedules leads to overheating of the valve body, wear of the cones and chain, which ultimately ends in expensive repairs or complete replacement of the unit. The correct replacement procedure, use of the original fluid and adherence to temperature conditions are the key to the long life of your transmission.
In this article we will look in detail at how to change the oil in a variator yourself. Nissan Note E12, what nuances exist when warming up the box and how to avoid critical errors that can damage the unit.
Selection of working fluid and technical requirements
For correct operation of the variator CVT in the model Nissan Note It is critical to use only specialized fluid. Standard gear oils for other types of gearboxes are not suitable here and can lead to instant failure of the clutches.
The manufacturer recommends using the original fluid Nissan NS-2 or Nissan NS-3 depending on the year of manufacture and modification of the variator. The specification is suitable for most E12 models with 1.2 and 1.5 liter engines NS-3, which provides better protection under high loads and temperatures.
Some owners try to save money by using analogues from third-party manufacturers, but this is a risky step. The chemical composition of the original oil is designed specifically for the friction characteristics of the belt and cones of this unit.
- 🛢️ Original liquid Nissan NS-3 (blue canister) is the best choice for reliability.
- 🛢️ Liquid Nissan NS-2 - suitable for earlier versions, but it is better to check by VIN.
- ❌ Cheap analogues can cause slipping and overheating of the transmission.
The volume of the system for a partial replacement is about 4-4.5 liters, while for a complete replacement (with flushing) it may require up to 8-9 liters. When purchasing, be sure to check the production date, as transmission fluid has a limited shelf life.
⚠️ Attention: The use of incompatible ATF (automatic transmission) fluid is strictly prohibited, as this will destroy the seals and change the pressure in the valve body.
Preparing the car and necessary tools
Before starting work, it is necessary to prepare the vehicle and workplace. Nissan Note E12 It has compact dimensions, but access to the variator pan can be difficult due to the protection of the crankcase and suspension elements. Make sure the machine is on a level surface.
You will need an inspection hole or a lift. If you work in a garage, make sure it is safe to jack up. Also prepare a set of wrenches, a funnel, an oil extraction hose and a new pan gasket (or sealant).
- 🔧 Set of sockets and ratchets (including 10, 14 and 17 mm wrench).
- 🧴 Container for draining used oil (volume of at least 5 liters).
- 🌡️ Motor hose and funnel for neatly pouring new fluid.
Don't forget to purchase a new oil filter if your CVT has one. In some modifications Nissan Note the filter comes complete with a pan, which simplifies the task, but in other cases the separator needs to be replaced separately.
☑️ Preparing for an oil change
Procedure for draining waste fluid
The first step is to warm up the transmission to operating temperature. Start the engine and drive about 10-15 kilometers until the oil warms up to 50-60 degrees Celsius. This is necessary so that the liquid becomes less viscous and flows out of the system as much as possible.
After stopping the engine, it is necessary to remove the crankcase protection. Unscrew the drain plug located on the variator pan. Be prepared for hot liquid to flow out, so immediately place the prepared container.
It is important not to confuse the drain plug with the filler plug. The drain plug is usually smaller and located lower. Carefully inspect the plug for metal shavings. The presence of small particles is acceptable, but large metal fragments indicate serious problems inside the unit.
- 🛢️ Wait until the oil drains completely (about 15-20 minutes).
- 🔍 Inspect the drain plug for magnets and shavings.
- 🧹 If necessary, remove the tray to replace the filter.
If you plan to replace the filter, unscrew the pan mounting bolts. Be careful as there is oil inside that will spill out when you remove the pan. Clean the pan of old sealant and dirt using a degreaser.
What to do if the plug does not unscrew?
If the drain plug is stuck, do not try to rip it off with brute force. Use penetrating lubricant (WD-40), let it sit for 10-15 minutes, then carefully try to unscrew it with an extension. Excessive force may strip the threads in the aluminum pan, requiring replacement.
Replacing the filter and cleaning the pan
Cleaning the pan and replacing the filter is a mandatory step that is often ignored when simply changing the oil. Metal dust, wear products and dirt accumulate in the pan, which will again enter the system the next time it is drained.
Remove the old filter if it is removable. Wash the tray and magnets with solvent until perfectly clean. Install a new filter and pan gasket. If the gasket is not included, use a high-quality automotive sealant, applying it in a thin layer.
Place the pan in place and tighten the bolts in a specific order to avoid distortion. The tightening should be moderate, since the aluminum of the pallet is easily deformed when twisted.
⚠️ Attention: Do not over-tighten the pan bolts. This can lead to deformation of the cover and loss of seal, which will cause oil to leak when heated.
- Every 30,000 km
- Every 50,000 km
- Every 60,000 km or less
- Never changed
Adding new fluid and checking the level
After assembling the pan and installing the drain plug, the filling process begins. Oil must be filled through the filler hole, usually located on the side or top of the gearbox housing. Use a hose and funnel for convenience.
Fill in about 4 liters of new fluid. Then start the engine and warm up the variator to operating temperature by switching the selector to different positions (P, R, N, D) and holding each position for 3-5 seconds. This is necessary to fill the torque converter and oil passages.
When the engine is warm (oil temperature 40-80°C), it is necessary to check the level. To do this, unscrew the control plug on the crankcase. If oil starts to leak out, the level is normal. If not, add oil in portions until a trickle appears.
- 🌡️ Oil temperature should be in the range of 40-80 degrees Celsius.
- 🔄 Switch the gear selector to distribute the fluid among the nodes.
- 📏 The level is considered correct if oil drips from the control hole.
After reaching the desired level, tighten the control plug with a new O-ring. Be sure to also check the engine coolant level, as some models have the CVT heat exchanger integrated into the cooling system.
Correctly checking the level is only possible when the engine is warm and the engine is running, otherwise you risk underfilling or overfilling the oil, which is critical for the variator.
Features of operation after replacement
After changing the oil, sharp accelerations and high engine speeds should be avoided in the first 500-1000 kilometers. This is the break-in period when the new fluid fills all the microscopic gaps and adapts to the friction materials.
Pay close attention to the vehicle's behavior. If jerking, kicking or extraneous noise occurs, you should immediately contact a specialist. Sometimes after changing the oil, it is necessary to adapt the variator through a diagnostic scanner.
Check the oil level periodically during the first weeks of operation. Sometimes, if the pan or plug is installed incorrectly, micro-leaks can occur, which will appear only after several heating-cooling cycles.
Observe replacement intervals. For Nissan Note E12 in city conditions and heavy traffic, the optimal interval is 40-50 thousand kilometers. Partial replacement every 30 thousand kilometers will extend the life of the transmission much longer.
Keep receipts and oil change records in the service book. When subsequently selling the car, this will become a strong argument for the buyer and will increase the market value of the car.
Common mistakes and ways to avoid them
One of the most common mistakes is overfilling the oil. Excessive amount of liquid leads to foaming, overheating and failure of the seals. Never rely solely on the "Min" and "Max" marks on the dipstick, if present, or use only the inspection hole.
Another mistake is using the wrong sealant. Conventional silicone sealants cannot withstand the temperatures and pressures in the variator. Use only special high-temperature compounds recommended by the manufacturer.
Ignoring the condition of the drain plug can also lead to problems. If the threads are stripped or the O-ring is damaged, there is no point in changing the oil as there will be a constant leakage.
Never mix different types of oils. If you do not know which oil was previously filled, it is better to perform a complete replacement with flushing, using a large amount of new fluid.

FAQ: Frequently asked questions
Is it possible to change the oil in a variator without removing the pan?
Technically, you can do a partial replacement by simply draining the oil through the drain plug. However, without replacing the filter and clearing the pan of sludge, the effectiveness of such replacement will be low and the service life of the transmission will be shortened.
How can I find out what kind of oil is in my car?
The best way is to contact the dealer using the VIN. You can also look at the markings on the old drain plug or, if you have access to documentation, find the specification for your year of manufacture. For E12 it is most often NS-3.
What to do if jerking occurs after changing the oil?
Jerks may be a consequence of adaptation. Drive 200-300 km in quiet mode. If jerking persists, it is possible that the wrong amount of oil was added or a low-quality fluid was used. Diagnosis required.
Do I need to warm up the variator in winter before replacing it?
Yes, warming up to operating temperature (50-60°C) is required so that the oil becomes liquid and flows out of the system as much as possible. Cold oil remains in the torque converter and channels, which distorts the amount of replacement.
How long does it take to change the oil?
If you have experience and a lift, the procedure takes about 1.5 - 2 hours. Including warming up, draining, filter replacement, filling and level checking.
