Nissan automatic transmission filter 3172628x0a: complete guide to replacement and selection

Automatic transmission system in modern cars Nissan requires perfect operation of the hydraulic circuit, where the fine filter plays a key role. Part numbers change frequently, and the number 3172628x0a is one of those that raises questions among owners when looking for components for repairs. This element is responsible for removing metal shavings, friction wear products and dirt from the working fluid, preventing clogging of solenoids and valves.

Ignoring the condition of the filter can lead to fatal consequences for the transmission, especially when it comes to popular models such as Nissan X-Trail or Nissan Qashqai. Many car owners mistakenly believe that the filter is a maintenance-free element, but this is a misconception that often results in expensive repairs to the valve body or the entire transmission.

Purpose and design features of filter 3172628x0a

Filter with serial number 3172628x0a is a complex structure consisting of a metal body, a filter element and sealing rings. Its main task is to ensure the purity of the oil circulating under pressure, which is critical for the proper operation of the torque converter and planetary gears.

Unlike simple engine oil filters, an automatic transmission filter operates in an aggressive environment, being constantly exposed to high temperatures and pressure. That is why the material of the filter element must have high heat resistance and throughput so as not to create excessive resistance to the flow of liquid.

🔍 The element delays metal particles of 20 microns in size, which are inevitably formed during gear friction.
⚙️ The design includes a built-in bypass valve that prevents oil starvation in case of severe clogging.
🛡️ Sealing elastic bands are made of oil-resistant material that is resistant to oxidation and swelling.

Despite its apparent simplicity, this component is the “heart” of the filtration system. If it fails or loses its seal, dirt will fall directly into the valve body, where the precise solenoids and channels are located. Restoration after such contamination requires complete disassembly and ultrasonic cleaning of all components.

⚠️ Attention: Using non-original filters with low-grade paper can lead to instant destruction of the filter element under oil pressure, which will cause cellulose to enter the torque converter.

Symptoms of wear and need for replacement

Determine that the filter 3172628x0a requires replacement, based on indirect signs that appear in the operation of the transmission. Owners often notice jerks when changing gears or delays when engaging reverse gear. These symptoms indicate that the filter capacity has decreased and the oil pressure has dropped.

Another warning sign is a change in the color and smell of the working fluid. If the oil darkens, acquires a burning smell and contains visible suspended matter, this is a sure sign that the filter can no longer cope with cleaning. In such cases, it is absolutely impossible to delay replacement.

🚗 The appearance of vibrations when the car moves at high speeds.
📉 Increased gear shift response time (kicks).
🔊 Noise and hum coming from the gearbox, especially when warming up.

It is important to understand that replacing the filter is often part of a larger procedure - a complete oil change. If you decide to change the fluid, then the filter Nissan must be updated. The old element, even if it looks intact, is already saturated with wear products and will not be able to work effectively with new oil.

Selection of original and high-quality analogues

There are many offers on the aftermarket for filters with the number 3172628x0a. Beware of fakes, which may not be visually different from the original, but have worse filtration characteristics. Original part from Nissan guarantees a precise fit and the use of materials designed to withstand extreme loads.

If the original is unavailable or too expensive, you can consider high-quality analogues from trusted manufacturers, such as Sakura, Knecht or Febi. However, when choosing an analogue, you must carefully check the presence of all o-rings in the kit and the quality of the filter material itself.

Product type	Manufacturer	Estimated cost	Features
Original	Nissan	High	Perfect compatibility, durability
Analogue Premium	Knecht, Mahle	Average	Excellent quality, often better than the original
Analog Budget	Sakura, Starline	Low	Acceptable for old cars, risk of low resource
Fake	Unknown	Very low	Risk of automatic transmission failure in the near future

When purchasing, be sure to check the packaging and the presence of holograms. The quality of the O-rings in the kit also plays a decisive role, since oil leakage through the gaskets can lead to a drop in pressure and gearbox failure.

⚠️ Attention: Never skimp on an automatic transmission filter. The cost of replacing a filter is several times lower than repairing a valve body or replacing solenoids that fail due to dirty oil.

How to check the authenticity of filter 3172628x0a?

To verify authenticity, pay attention to the quality of the casting of the case, the clarity of the markings and the quality of the rubber seals. Original seals are always smooth and elastic, without burrs. The body must be stamped with the markings corresponding to the Nissan catalog.-->

Step-by-step instructions for replacing the filter

Replacing the filter 3172628x0a is a procedure that requires certain preparation and tools. You will need a lift or inspection hole, a set of wrenches, a container to drain the old oil, a new filter and fresh transmission fluid. Don't forget to have a rag ready to remove spills.

First, you need to warm up the engine and transmission to operating temperature so that the oil becomes thinner and easier to drain. Then turn off the engine, place the car on a level surface and securely support it. Remove the crankcase protection, if installed.

🔧 Prepare a container with a volume of at least 5 liters to drain the waste liquid.
🛠️ Use a torque wrench to tighten the drain plug and secure the filter.
🧤 Wear protective gloves as gear oil can cause skin irritation.

Unscrew the pan drain plug and drain the old oil. After this, unscrew the bolts securing the pallet and carefully remove it. Be careful as there may be oil left inside. Remove the old filter, which is usually secured with bolts or clips, and clean the seat of dirt and sealant residue.
