Ignoring the planned replacement of this element leads to a decrease in pressure in the system, overheating and premature failure of the clutches and torque converter. Nissan Teana J31 It was equipped with both 4-speed and 5-speed automatic transmissions, and in both cases the condition of the filter is a key factor in reliability. Filter clogging is one of the most common causes of valve body failure on runs over 100,000 km. Understanding the design and maintaining it regularly will help extend the life of your transmission for many years.
Design and types of filters for Teana J31
Transmission filtration system Nissan Teana The structure is quite simple, but it has its own design features that are important to consider when making repairs. Depending on the year of manufacture and the type of installed machine (JR401E or RE5R05A), two types of filter can be used: paper (cardboard) or metal mesh. Most owners are faced with a paper filter, which is located inside the pan.
The paper element has a high throughput and effectively retains fine suspended matter, but at the same time has a limited resource. A metal mesh, if provided for in the design, is more durable, but does not cope well with fine dirt, which over time clogs the valve body channels.
It is important to understand that the filter is not a consumable item that can simply be washed and reinstalled. When heavily contaminated, its pores become clogged, creating a vacuum at the pump inlet, which leads to cavitation and destruction of parts.
- 🔧 The paper filter is a disposable element that requires replacement at every oil change.
- 🔧 Metal mesh - can be cleaned, but often must be replaced if mechanical damage occurs.
- 🔧 The pallet gasket must be replaced, as the old one loses its tightness.
Signs that the filter needs to be replaced
You can determine that the filter is clogged not only by mileage, but also by indirect signs in the behavior of the car. On Nissan Teana J31 this often manifests itself in the form of jerks when changing gears, especially when moving from second to third or from third to fourth. If you feel that the transmission “thinks” for too long or jerks when starting, this is a sure sign of hydraulic problems.
Another warning sign is a change in the color and smell of the transmission fluid. Fresh oil should have a bright red color and a specific sweetish smell. If the liquid has turned dark brown or black, and a burning smell emanates from it, it means that the filter is no longer coping with its functions, and wear products are circulating through the system.
Sometimes the problem may be accompanied by noise during the operation of the gearbox, which can be heard in neutral gear or when coasting. This indicates that the pump is experiencing an oil shortage due to a clogged filter and begins to suck in air.
- 🚗 Jerks and jolts when changing gears at any speed.
- 🚗 Delays when engaging reverse and first gear (delay up to 2 seconds).
- 🚗 The Check Engine light or transmission fault icon comes on.
⚠️ Attention: If you notice a burning smell from the oil, use of the vehicle should be stopped immediately until the reasons are clarified. Continuing to drive can lead to critical overheating and complete destruction of the gearbox.
Selection of original and analog spare parts
When choosing automatic transmission filter for Nissan Teana You should be guided not only by price, but also by the quality of the material. The original Nissan filter (part number 31726-AX000 or equivalents depending on the type of automatic transmission) is made of high-quality filter paper, which retains its properties in the aggressive environment of transmission oil.
There are high-quality analogues on the market from oil and filter manufacturers, such as Mann, Mahle or special brands specializing in Japanese cars. However, you should be careful with cheap fakes, which may not withstand the pressure in the system and rupture, which will lead to catastrophic consequences for the valve body.
When purchasing, be sure to check the kit's contents. A good service kit should include not only the filter, but also a new pan gasket and sometimes a drain plug with a new O-ring. This will save you time and eliminate the risk of leaks.

Preparing for the replacement procedure
Before starting work, you need to prepare the car and the necessary tools. The process of replacing the filter Nissan Teana J31 requires access to the transmission pan, which is located underneath the vehicle. You will need a reliable lift or inspection pit, as well as a set of wrenches and sockets.
Before starting work, the engine must be warmed up to operating temperature so that the oil becomes less viscous and drains easier. However, be careful, hot oil can cause burns. Prepare a container with a volume of at least 6-8 liters to drain the waste liquid. You will also need rags, degreaser and new transmission fluid.
This means that you need to unscrew all the bolts around the perimeter, carefully bend the pan and drain the remaining oil that has accumulated there.
☑️ Preparing to replace the filter
⚠️ Warning: Do not attempt to remove the pan bolts unless the vehicle is securely supported on a lift or stands. The vehicle may fall off, causing serious injury.
Step-by-step replacement instructions
The filter replacement process begins with draining the transmission fluid. Unscrew the drain plug of the pan and allow the oil to completely drain into the prepared container. After this, you can begin to unscrew the bolts securing the pallet. Do this in a criss-cross pattern to avoid deforming the pallet.
When all the bolts are unscrewed, carefully bend the pallet. Be prepared for the remaining oil to spill onto the floor or onto you, so it is better to use a wide basin. After removing the pan, you will see the filter itself, which is attached to the valve body body. Unscrew the filter mounting bolts and remove it.
Thoroughly clean the tray of metal shavings and dirt. Use a magnet, if there is one at the bottom of the pan, and collect all the metal particles. Clean the filter seat on the valve body so that the new seal fits tightly and airtight.
Install the new filter and tighten its bolts to the recommended torque. Install a new pan gasket and press the pan into place. Tighten the pan bolts in a crisscross pattern to ensure an even fit.
What to do if the pallet is deformed?
If the pan is dented or warped, it will need to be straightened or replaced. Incorrect pan geometry can lead to leaks and oil leaks, even when using a new gasket.
Before installing the pallet, apply a thin layer of sealant to the corners and joints if recommended by the manufacturer, but do not overdo it so that excess does not end up inside the box.
Level check and operation control
After assembling the transmission, new oil must be added. Use only the fluid recommended by the manufacturer (usually Nissan Matic S or J). Fill oil through the dipstick hole or filler neck, checking the level.
Start the engine and let it idle. Switch the automatic transmission selector to all positions, holding each position for 3-5 seconds to allow the oil to circulate throughout the system. Then return the selector to position P or N.
Check the oil level with the engine running. It should be between the Hot marks on the dipstick. If the level is low, add oil. If the level is higher than normal, drain the excess as overfilling can cause the oil to foam and overheat.
The correct oil level is the key to stable operation of the automatic transmission. Underfilling causes cavitation and overheating, overfilling causes foaming and loss of pressure.
After replacing, drive the car for several kilometers and check for leaks. If everything is in order, the replacement procedure is complete. It is recommended to repeat the level check after 100-200 km, as oil may settle in the torque converter.
- 🛢️ Use only original liquid or certified analogues.
- 🛢️ Do not allow dirt to enter the system when pouring oil.
- 🛢️ Check the tightness of all connections after the trip.
Frequent maintenance errors
Many car owners make mistakes when trying to save time or money on maintenance. One of the most common mistakes is trying to wash the filter instead of replacing it. Even if the filter is metal, it may be so clogged that washing it will not help restore its capacity.
Another mistake is using the wrong sealant. Some technicians use silicone sealants, which are not designed to work in the aggressive environment of transmission oil. This leads to the dissolution of the sealant, its entry into the hydraulic unit and subsequent clogging of the channels.
You should also avoid using oils with improper tolerances. Different types of gearboxes require different viscosity and chemical properties of the oil. Using the wrong oil can lead to rapid wear of the clutches and malfunction of the torque converter.
Is it possible to replace the filter without removing the pan?
No, on the Nissan Teana J31 the filter is located inside the pan, so replacing it is impossible without removing the pan and draining the oil.
Sometimes craftsmen forget to replace the pan gasket using the old one. This is almost guaranteed to lead to a leak, since the gasket is deformed and loses its tightness upon first heating.
