Automatic transmission in Nissan Qashqai is a complex hydromechanical unit that requires regular attention. Many owners mistakenly believe that transmission fluid changes its service life on its own, without noticing critical wear of components.
The key element responsible for the cleanliness of the oil in the valve body is automatic transmission filter. Its condition directly affects the smoothness of switching, the operation of solenoids and the service life of the entire assembly. Ignoring this detail can result in costly repairs or complete replacement of the transmission.
The role of the filter in the operation of the torque converter
The automatic transmission system operates on the principle of circulating fluid under high pressure. Inside the housing there is a metal mesh or paper element that traps wear products: metal shavings, friction dust from clutch discs and sealant residues.
If automatic transmission filter becomes clogged, the oil flow to the valve body weakens. This causes a drop in pressure, slipping of the clutches and sharp shocks when changing gears. In some cases the control unit Nissan Qashqai puts the box into emergency mode, limiting the number of available speeds.
A design feature of many automatic transmissions Nissan is the presence of two filters: coarse filters (in the pan) and fine filters (inside the hydraulic unit). The first is available for replacement during standard service, while the second requires removal of the entire transmission.
When replacement is necessary: signs of malfunction
The manufacturer often claims a “maintenance-free” gearbox, but practice shows that the oil change interval should be no more than 60,000 kilometers. In this case, the filter is changed along with the liquid.
You may suspect problems with the filter based on the following symptoms:
- 🚗 Dotted or jerky operation of the box when switching from first to second gear.
- 🛑 Increased response time when switching from mode
PinDorR. - 🔥 The appearance of extraneous hum or vibration, especially during acceleration.
These signs often indicate that strainer so clogged that it does not allow the required volume of oil to pass through. Without sufficient pressure, the friction discs do not press tightly, which leads to their rapid burnout.
⚠️ Attention: If you notice a burning smell from the transmission oil, this is a sure sign that the filter has stopped cleaning and the clutches have already begun to overheat. Stop using the vehicle immediately.

Original spare parts and high-quality analogues
When choosing automatic transmission filter it is important to understand the differences between designs for different generations Nissan Qashqai. For models with a variator (CVT) and a classic automatic (Jatco), the filters are fundamentally different in shape and method of attachment.
Original filter from Nissan usually supplied complete with pan gasket and bolts. This guarantees a perfect fit and no leaks. However, the cost of the original may be inflated, especially if you order it through dealerships.
There are a number of trusted manufacturers offering high-quality analogues. They often use a denser mesh or improved paper, which extends the life of the element. The main condition is compliance with the catalog number.
- 🔧 NSK is a well-known Japanese brand that often supplies components for lubrication systems.
- 🔧 Victor Reinz - a leader in the production of gaskets and seals, their filters are highly accurate.
- 🔧 Meat & Doria is a reliable European brand with a wide catalog of transmission filters.
You shouldn't save money by buying cheap Chinese copies without a brand. Poor quality mesh material can quickly fall apart, allowing particles to enter the valve body, causing permanent damage.
How to check the filter for clearance?
Remove the old filter and look at it against the light. If you see a lot of dark spots and clogged cells, then the resource is exhausted. If the mesh is rusty or deformed, replacement is required even with low mileage.
Preparatory stage and necessary tools
Before starting work, it is necessary to ensure access to the transmission pan. This often requires removing the crankcase protection and, possibly, part of the suspension or exhaust system elements, depending on the modification Nissan Qashqai.
You will need a tool kit including 10mm, 14mm and 17mm wrenches, as well as a torque wrench to properly tighten the pan bolts. Do not forget to prepare a container for draining waste liquid with a volume of at least 5 liters.
It is also important to prepare new consumables: automatic transmission filter, a pan gasket (or sealant if the gasket is not included) and fresh transmission oil. For Nissan It is recommended to use standard fluids NSF or ESN depending on the type of box.
☑️ Preparation for replacement
Step-by-step instructions for replacing the filter
The replacement process begins with draining the used fluid. Unscrew the pan drain plug, let the oil drain completely, and then remove the pan itself. Be careful not to spill oil on hot exhaust system components.
After removing the pan, you will see the old filter bolted to the valve body body. Carefully unscrew the fasteners and remove the filter. If it sticks, do not use a pry bar to avoid damaging the seat.
Clean the tray of metal shavings and dirt. The magnets installed at the bottom of the tray must be thoroughly washed in gasoline or solvent. This is an important step, as accumulated chips indicate internal wear.
Install new automatic transmission filter, after making sure that the rubber seal sits evenly. Tighten the mounting bolts crosswise, without applying excessive force, so as not to strip the threads in the aluminum housing.
Before installing the pan, apply a thin layer of sealant to the edge of the pan if a sealant gasket is used. Reinstall the pan and tighten the bolts to the specified torque (usually around 10-12 Nm).
- 🛠️ Fill in fresh oil through the dipstick or filler hole.
- 🛠️ Start the engine and warm up the transmission to operating temperature.
- 🛠️ Check the oil level at the control hole with the engine running.
Before filling in new oil, it is recommended to crank the crankshaft with the starter without starting the engine so that the pump drives the liquid through the new filter and fills the valve body.
Features of working with a CVT variator
For owners Nissan Qashqai with the JF011E (RE0F10A) variator, the procedure has its own nuances. These boxes use two filters: coarse filter (in the tray) and fine filter (inside the housing). The second filter is often not changed during scheduled maintenance, but when the mileage is more than 120,000 km, its replacement is critical.
The fine filter is located deep in the housing and requires removal of the hydraulic unit. This is a complex procedure that requires disassembling a significant part of the unit. Errors during assembly can lead to pressure leaks and failure of the variator.
It is important to use only specialized oil for CVTs. Using regular ATF can cause the cones and belt to wear out quickly. Manufacturer Nissan recommends liquid NSF or ESN-2.
For Nissan CVTs, replacing the fine filter is mandatory when the mileage exceeds 100,000 km, since its clogging leads to a drop in pressure and belt slippage.

| RE0F09A | Automatic (4 speed) | 31328-1MF0A | Nissan ATF Matic J | 4.0 |
Please note that the numbers shown in the table are approximate numbers. Before purchasing, always check the vehicle's VIN with the supplier's catalogue.
⚠️ Attention: Never mix different types of transmission fluids. A mixture of NS-2 and NS-3 oils can lead to a change in viscosity and destruction of the seals inside the variator.
What to do if the filter is torn?
If during removal the old filter falls into pieces, it is necessary to remove the hydraulic unit and wash all channels. Fractured mesh may jam the solenoids or damage the pump. This is a critical situation that requires a full diagnosis.
Common replacement errors and their consequences
One of the most common mistakes is improperly tightening the pan bolts. Over-tightening will cause the aluminum housing to deform and create cracks through which oil will leak. Tightening too loose will cause gasket leakage.
Another mistake is not cleaning the pan magnets. If you leave old metal shavings, they will again enter the lubrication system and clog the new one. automatic transmission filter and will accelerate pump wear.
The wrong choice of fluid also leads to problems. Fluid with the wrong viscosity index may not provide the correct pressure to shift gears, causing jerking and knocking.
Proper tightening of the pan bolts using a torque wrench is the key to avoiding leaks and maintaining the tightness of the transmission.
FAQ: Answers to popular questions
Is it possible to change only the filter without changing the oil?
Theoretically it is possible, but it is pointless. The new filter will quickly become clogged with old dirty oil, and dirt from the old oil will remain in the system. Always change the filter along with the fluid.
How often do you need to change the filter on a Nissan Qashqai?
The recommended interval is every 60,000 km. If the car is used in difficult conditions (traffic jams, towing, off-road), the interval should be reduced to 40,000 km.
Do I need to rinse the box before replacing the filter?
Washing with special products is not recommended, as it can wash away dirt from the walls and clog the new filter. It's better to just drain the old oil and fill in new oil.
Where is the automatic transmission filter on a Nissan Qashqai?
The coarse filter is located inside the oil pan. The fine filter (if equipped) is located inside the gearbox housing, behind the valve body.
What happens if you don't replace a clogged filter?
The box will go into emergency mode, jerking will begin, and then the clutches will completely wear out and the valve body will fail. Repairs will cost tens of thousands of rubles.
