Automatic transmission on cars Nissan Teana is a complex and sensitive unit that requires regular maintenance. Many owners mistakenly believe that the fluid filled from the factory is designed to last a lifetime, but this misconception can lead to expensive transmission repairs. Under the conditions of Russian roads and climate, the oil life is significantly reduced due to overheating and high load.
Timely replacement of transmission fluid not only prolongs the life of the unit, but also improves gear shift dynamics, making the ride more comfortable and smoother. Ignoring maintenance regulations often causes jerking, kicking and noise during operation. variator or a classic automatic, depending on the generation of the model.
Selecting transmission fluid for Nissan Teana
One of the most critical maintenance mistakes is using the wrong type of oil. For Nissan Teana Depending on the year of manufacture and type of transmission, the manufacturer sets strict requirements for the viscosity and chemical composition of the fluid. Incorrectly selected oil can lead to rapid wear of the clutches, slipping and failure of the valve body.
For classic automatic transmissions (for example, RE4F04B or RE4F02B on early models), it is recommended to use the original fluid Nissan Matic D or Nissan Matic J. These specifications are developed taking into account the characteristics of the friction linings and valves of these particular units. The use of analogues without appropriate certification is strictly not recommended.
If you own a more modern version Teana with a variator (CVT), the situation changes dramatically. This requires a specific liquid. Nissan CVT Fluid NS-2 or NS-3. Mixing different types of fluids or using oil from a classic automatic transmission in a CVT will cause irreversible damage to the belt drive and cones. Mixing NS-2 and NS-3 oils is strictly prohibited, as this will destroy the rubber seals and change the coefficient of friction.
- π Always check the specifications on the filler cap or service book before purchasing.
- π Buy oil only from official dealers or certified points of sale to avoid counterfeits.
- βοΈ Keep in mind that the volume of oil during a partial replacement differs from the full volume in the cooling system.
Instruments and preparation for the procedure
Before starting work, it is necessary to prepare a workplace and the necessary set of tools. Oil change process Nissan Teana requires access to the underside of the vehicle, so a lift or secure overpass will be a must. Working on the ground or in a hole without sufficient height can be unsafe and uncomfortable.
You will need a set of wrenches and sockets, including a specific size for the drain plug, which is often different from the standard bolt sizes. Also, do not forget to prepare a container for draining waste, a funnel for pouring new oil and clean rags. The presence of a jack and supports will provide additional safety when working under the car.
βοΈ Preparing for an oil change
It is also important to take into account the temperature regime. The oil must be heated to operating temperature so that its viscosity decreases and it can completely drain from the box body. This will ensure a better drainage of the old oil and allow you to correctly check the level of the new fluid.
Why is the pan gasket important? When draining the oil, the transmission pan must be removed to clean the magnets and replace the filter. The old gasket is often deformed and reuse may cause leakage.-->
Step-by-step instructions for changing the oil
The replacement process begins with warming up the engine and transmission. Start the engine and let it run in Drive and Reverse for a few seconds, switching the selector. This will allow the oil to warm up to a temperature of 40-50 degrees Celsius, which is the optimal condition for draining.
After warming up, place the car on a level surface and secure it with the handbrake. Raise the front of the car and remove the crankcase protection. Locate the drain plug on the transmission pan. It is usually located on the bottom side, towards the back of the tray. Carefully unscrew the plug, positioning the container for drainage.
After the oil has completely drained, you need to remove the pan itself. This will allow you to access the coarse filter and magnets that collect metal shavings. Clean the magnets from deposits and wash the tray with gasoline or solvent. If the filter cannot be replaced, it must also be washed thoroughly.
Install a new filter (or a cleaned old one) and screw on the pan with a new gasket. Tighten the pan bolts to the torque recommended by the manufacturer to avoid stripping the threads or damaging the aluminum. After this, tighten the drain plug with a new copper washer.
Drive and Reverse for a few seconds, switching the selector. This will allow the oil to warm up to a temperature of 40-50 degrees Celsius, which is the optimal condition for draining.
