An automatic transmission is a complex hydromechanical unit that requires impeccable care and the use of specific consumables. For most front-wheel drive and all-wheel drive models Nissan and Infiniti the main requirement is to use the original liquid Nissan Matic Fluid S. This is not just a lubricant, but a high-tech composition that ensures smooth gear shifting and cooling of friction discs.
Many car owners make the fatal mistake of trying to save money and replace the original oil with universal analogues or products from other brands that supposedly “match the specifications.” However, the valve body and clutches of Japanese gearboxes Jatco tuned to the specific viscosity and additive package of the original. Ignoring this rule can lead to slippage and costly repairs.
What is Nissan Matic Fluid S and who is it for?
Liquid Nissan Matic Fluid S (often referred to as Matic S) is designed specifically for automatic transmissions equipped with a torque converter. This oil is classified according to the standard DEXRON III, but has a unique formula adapted to the materials of seals and friction linings used in the concern’s gearboxes. The main task of this fluid is to transmit torque from the engine to the wheels, as well as lubricate the gears and remove heat.
A special feature of this transmission fluid is its color: it usually has a bright red tint. This allows you to visually monitor the level and quality of the oil during operation. If you find that the fluid in the transmission pan has turned brown or black with a burning smell, this is a sure sign that the life of the clutches has been exhausted and immediate replacement is required.
The Matic S specification is used in a wide range of vehicles including Nissan X-Trail, Nissan Qashqai, Teana, Almera and many other models released since the early 2000s. It is important to understand that even within the same model, different types of boxes could be installed in different years of production, so always check the service book before purchasing.
- 🔴 Ensures stable operation of the torque converter at high temperatures.
- ⚙️ Protects metal surfaces from wear and corrosion.
- 📉 Maintains optimal viscosity over a wide temperature range.
Differences from other specifications and risks of confusion
In the line of transmission fluids Nissan There are many specifications: Matic D, Matic J, Matic K, Matic L and others. Each of them has its own unique properties and is used in specific types of gearboxes. For example, Nissan Matic J used in CVTs and is not suitable for classic automatic transmissions, but Matic D used in older models. Using the wrong specification is guaranteed to damage the unit.
Mixing Nissan Matic Fluid S with other types of oils is strictly unacceptable. The chemical composition of additives in different fluids can react, causing sedimentation, oil curdling, or loss of lubricating properties. Even if the colors of the oils match, this does not mean they are compatible. In the worst case, this will lead to jamming of the valve body solenoids.
Owners often wonder whether it is possible to use an analogue from another manufacturer, for example, Idemitsu or Mobil, if the original has run out. It is technically possible to find an analogue with approval DEXRON III, but the risk of loss of warranty and unstable operation of the automatic transmission is too great. The best solution is to use only certified oil.
⚠️ Attention: Never add fluid with a different specification to the gearbox, even in an emergency on the highway. This can lead to irreversible destruction of the friction discs during the first gear shift.
- ❌ It is forbidden to mix Matic S with Matic J (CVT) or Matic K (CVT).
- ✅ Use only the original or certified analogues marked DEXRON III.
- 🛑 When purchasing, check the integrity of the packaging and the presence of holograms.
- Classic automatic (AT)
- CVT (CVT)
- Robot (DCT)
- Mechanical (MT)
How to determine the need to change the oil in an automatic transmission
Car manufacturers often claim that transmission fluid has a “lifetime” service life, but this is a marketing ploy that does not take into account actual operating conditions. In city conditions with frequent traffic jams, overheating and short trips, oil degrades much faster. Optimal replacement interval for Nissan Matic Fluid S is every 60,000 kilometers or every 4 years, whichever comes first.
Symptoms of oil aging may not be immediately noticeable, but over time they become critical. The smoothness of switching is disrupted, jerks and shocks appear when switching on modes D or R. An increase in transmission response time may also be observed. If you hear an extraneous hum or vibration that increases with movement, this is a reason to immediately check the level and condition of the fluid.
Visual diagnostics is the easiest way to assess the condition of the oil. Pull out the dipstick (if your model has one) and apply a drop onto a white napkin. Fresh oil will be clear and red. If there are dark spots on the napkin, metal shavings, or cloudiness is visible, replacement cannot be delayed.
Before starting diagnostics, be sure to warm up the engine to operating temperature and turn on all automatic transmission modes one by one, holding each mode for 5-10 seconds. This will ensure the oil level is checked accurately.
- 🔍 Check the oil level when the engine is warm on a flat surface.
- 🛢️ Watch out for the smell: burnt oil requires urgent replacement and checking of the clutches.
- 📉 A decrease in fluid volume may indicate leaks through the seals.
Technology for partial and complete fluid replacement
There are two main ways to replace transmission fluid: partial and complete (hardware). A partial replacement involves draining the oil only from the transmission pan. In this case, about 30-40% of the volume is renewed, since the bulk of the fluid remains in the torque converter and oil channels. This is a simple method that you can do yourself, but it requires regular repetition every 10-15 thousand kilometers.
A complete replacement is carried out using special equipment that replaces the old oil with new oil under pressure. This method allows you to update up to 95-98% of the volume of working fluid at a time. For boxes with mileage exceeding 100,000 km and which have not been previously serviced, a complete replacement can be risky, since detergent additives can wash away dirt and clog the thin channels of the valve body.
If you decide to carry out a partial replacement yourself, you will need to remove the crankcase protection, unscrew the drain plug and pan. After draining the old fluid, it is necessary to clean the pan from metal shavings and dirt, replace the magnets and install a new automatic transmission filter, if it is removable. Then the pan is sealed and new oil is poured in. Nissan Matic Fluid S.
☑️ Preparing for an oil change
It is important to follow the exact procedure to avoid damaging the sensors and seals. After filling in new oil, you need to start the engine, click through all gears and check the level again. If the level drops, add oil to the mark Hot. If the level is higher than normal, the excess must be drained, as foamed oil can cause pressure problems.
⚠️ Attention: When performing a complete hardware replacement, make sure that the specialist has experience working with boxes Jatco. Incorrect displacement pressure can damage clutches that cannot withstand sudden changes in fluid properties.
Compatibility table and refill volume
When scheduling service, it is important to know the exact amount of transmission fluid required for your model. This parameter depends on the type of gearbox and its modification. Below is a table with approximate data for popular models using Nissan Matic Fluid S.
| Car model | Box type | Volume for partial replacement (l) | Volume with full replacement (l) |
|---|---|---|---|
| Nissan X-Trail (T31) | 4-st. machine | 3.5 - 4.0 | 7.5 - 8.0 |
| Nissan Teana (J31/J32) | 4-st./5-st. machine | 4.0 - 4.5 | 8.5 - 9.0 |
| Nissan Qashqai (J10) | 4-st. machine | 3.5 | 7.0 |
| Nissan Almera Classic | 4-st. machine | 3.5 | 7.5 |
| Nissan Pathfinder (R51) | 5-st. machine | 4.5 | 9.0 |
Please note that the data provided is indicative only. The exact volume is always indicated in the technical documentation for the car or on a plate under the hood. Using more fluid will not improve the performance of the box, but will only create excess pressure in the system.
Why is it important to change the automatic transmission filter?
The automatic transmission filter retains wear products and metal shavings. If it is not changed, it becomes clogged, which leads to a decrease in oil pressure and overheating of the box. An old filter may begin to let dirt through, clogging the valve body.
Useful tips for extending the life of an automatic transmission
Even high quality oil Nissan Matic Fluid S will not save the gearbox from premature wear due to improper use. Avoid sudden starts from a standstill, slipping in mud or snow, as well as prolonged slipping when driving off-road. Transmission overheating is the main enemy of the torque converter and clutches.
When driving in traffic jams or on long descents, it is recommended to switch the transmission to manual mode or use lower gears to avoid frequent up-down switching, which causes overheating of the oil. If you are towing a trailer, make sure that it does not exceed the permissible weight and that the special towing mode is set in the vehicle settings.
Regular diagnostics of the condition of the valve body and solenoids also contributes to the longevity of the unit. If you experience the slightest jerks or delays in gear shifting, do not delay your visit to the service center. The sooner a problem is identified, the cheaper it will be to fix it.
Regularly changing the oil and filter, as well as avoiding overheating, is 90% of the success in long-term operation of a Nissan automatic transmission.

Frequently asked questions and answers
Car owners often face questions related to choosing and replacing transmission fluid. Below we have collected answers to the most popular questions that will help you avoid mistakes during maintenance.
Can Nissan Matic S be used with a continuously variable transmission (CVT)?
No, absolutely not. CVTs require the use of specialized fluids, such as Nissan Matic J or Nissan Matic K. Using a Matic S in a CVT will cause the belt to slip and destroy the CVT cones in no time.
How many liters of oil do you need to buy for a complete change?
A complete replacement using the displacement method usually requires 8-10 liters of oil. For a partial replacement, 3-5 liters are enough. It is recommended to always buy a small supply of oil, as the level may require adjustment after the warm-up cycle.
What to do if you overfilled the automatic transmission with oil?
Excess oil in the transmission can cause it to foam and escape through the vents. Excess oil must be drained to the level Hot when the engine is warm. If the oil has already begun to foam, a complete replacement with flushing of the system will be required.
Is it necessary to warm up the transmission in winter?
Yes, definitely. Cold oil has increased viscosity and circulates worse through the system. Warm-up mode N or D holding the brake for 1-2 minutes will ensure that all components are lubricated before starting to move.
How often do you need to change the automatic transmission filter?
It is recommended to change the filter at every complete oil change, that is, every 60,000 kilometers. If the filter is non-separable and built into the hydraulic unit, its replacement can only be done during repair or deep overhaul of the unit.
