By "settings" in this manual is meant not a single procedure for adjusting any of the parameters of the car's systems, but a whole range of adjustments that allow you to achieve maximum engine efficiency.

If the owner of a new car, from the date of purchase, strictly adhered to the schedule of routine maintenance procedures (see the Maintenance Schedule chapter), performed frequent checks of critical parameters, maintained the required level of lubricating fluids, the engine will very rarely need to perform additional maintenance and refurbishment (beyond the replacement of affected increased wear of components and consumables).

On the other hand, in the event of a careless attitude to the implementation of regular maintenance procedures and violation of the established deadlines for conducting inspections, the efficiency of the engine's output will sooner or later decrease. The likelihood of such a situation is especially high in the case of purchasing a used car. In such cases, it becomes necessary to perform a set of settings for the power unit in excess of the amount of work on the current maintenance of the car.

The first step in tuning or diagnosing malfunctions of a low-output engine is always Compression of the engine in the cylinders (see the Engine chapter), the analysis of the results of which allows you to assess the general condition of the internal components of the engine and outline a plan for future adjustment and / or restoration work. For example, if the Engine Compression showed signs of severe internal engine wear, a simple set of adjustments would not be enough to correct the situation and would be a waste of time and money. Because of the value of information obtained from a compression test, it should be performed by a suitably experienced and qualified mechanic who has the necessary diagnostic tools.

Below are lists of basic tuning procedures that allow you to achieve maximum efficiency of return from an engine that is in good mechanical condition.

An oil change in a Nissan Micra gearbox is most often associated with the repair of the automatic transmission itself, or it is replaced with a new one in the course of work to eliminate oil leaks, since it must be drained for work. The oil in the automatic transmission is filled in by the manufacturer once for the entire life of the car. It is recommended to entrust the oil change in the Nissan Micra automatic transmission to professionals, but in some cases this operation can be done on your own.

Functions of ATF oil in automatic transmission Nissan Micra:

effective lubrication of rubbing surfaces and mechanisms;
reduction of mechanical load on the nodes;
heat dissipation;
removal of microparticles resulting from corrosion or wear of parts.

The color of ATF oil for automatic transmission Nissan Micra allows not only to distinguish oils by type, but helps to find out in the event of a leak from which system the fluid has escaped. For example, the oil in automatic transmission and power steering has a red tint, antifreeze is green, and in the engine it is yellowish.

Reasons for oil leakage from automatic transmission in Nissan Micra:

wear of automatic transmission seals;
wear of the shaft surfaces, the occurrence of a gap between the shaft and the sealing element;
wear of the automatic transmission sealing element and the speedometer drive shaft;
play of the input shaft of the automatic transmission;
damage to the sealing layer in the joints between parts of the automatic transmission: sump, automatic transmission housing, crankcase, clutch housing;
loosening of the bolts that provide the connection of the above parts of the automatic transmission;

A low oil level in a Nissan Micra automatic transmission is the main cause of clutch failure. Due to the low fluid pressure, the friction clutches are poorly pressed against the steel discs and do not have enough contact with each other. As a result, the friction linings in the Nissan Micra automatic transmission become very hot, charred and destroyed, significantly polluting the oil.

Due to a lack of oil or low-quality oil in the Nissan Micra automatic transmission:

plungers and channels of the valve body are clogged with mechanical particles, which leads to a shortage of oil in the packages and provokes wear of the bushing, rubbing parts of the pump, etc.;
the steel disks of the gearbox overheat and wear out quickly;
rubber-coated pistons, thrust discs, clutch drum, etc. overheat and burn;
the valve body wears out and becomes unusable.

Contaminated automatic transmission oil cannot fully remove heat and provide high-quality lubrication of parts, which leads to various malfunctions of the Nissan Micra automatic transmission. Heavily contaminated oil is an abrasive suspension that, under high pressure, creates a sandblasting effect. Intense impact on the valve body leads to thinning of its walls at the locations of the control valves, as a result of which numerous leaks can occur.
You can check the oil level in a Nissan Micra automatic transmission using a dipstick. The dipstick has two pairs of marks - the upper pair of Max and Min allows you to determine the level in hot oil, the lower pair - in cold. Using the dipstick, it is easy to check the condition of the oil: you need to drop the oil onto a clean white cloth.

When choosing a Nissan Micra automatic transmission oil for replacement, you should be guided by a simple principle: it is best to use the oil recommended by Nissan. At the same time, instead of mineral oil, semi-synthetic or synthetic oil can be poured, but in no case should an oil “class lower” than prescribed be used.

Synthetic oil for automatic transmission Nissan Micra is called "non-replaceable", it is poured for the entire life of the car. Such oil does not lose its properties under the influence of high temperature and is designed for a very long period of use of Nissan Micra. But we must not forget about the appearance of a mechanical suspension as a result of friction clutch wear with a very significant mileage. If the automatic transmission has been operated for some time in conditions of lack of oil, it is necessary to check the degree of its contamination and, if necessary, replace it.

Ways to change the oil in a Nissan Micra automatic transmission:

Partial oil change in a Nissan Micra box;
Complete oil change in a Nissan Micra box;

A partial oil change in a Nissan Micra automatic transmission can be done independently. To do this, just unscrew the drain on the pallet, driving the car onto the overpass, and collect the oil in a container. Usually up to 25-40% of the volume flows out, the remaining 60-75% remain in the torque converter, that is, in fact, this is an update, not a replacement. To update the oil in the Nissan Micra automatic transmission in this way to the maximum, 2-3 replacements will be required.

A complete oil change for the automatic transmission of Nissan Micra is carried out using an automatic transmission oil change unit, auto repair specialists. In this case, more ATF oil will be required than the Nissan Micra automatic transmission can accommodate. Flushing takes one and a half or double the volume of fresh ATF. The cost will be more expensive than a partial replacement, and not every car service provides such a service.
Partial ATF oil change in the Nissan Micra automatic transmission according to a simplified scheme:

We unscrew the drain plug, drain the old ATF oil;
We unscrew the automatic transmission pan, which, in addition to the bolts holding it, is treated along the contour with a sealant.
We get access to the automatic transmission filter, it is advisable to change it at each oil change, or rinse it.
At the bottom of the pallet there are magnets that are necessary to collect metal dust and chips.
We clean the magnets and wash the pallet, wipe it dry.
Install the automatic transmission filter in place.
We install the automatic transmission pan in place, replacing the gasket of the automatic transmission pan if necessary.
We twist the drain plug, replacing the drain plug gasket for the automatic transmission.

We fill the oil through the technological filler hole (where the automatic transmission dipstick is located), using the dipstick we control the oil level in the automatic transmission to a cold one. After changing the oil in the automatic transmission, it is important to check its level after driving 10-20 km, already with the automatic transmission warmed up. Top up to level if necessary. The regularity of changing the oil depends not only on the mileage, but also on the nature of the ride on the Nissan Micra. You should focus not on the recommended mileage, but on the degree of contamination of the oil, systematically checking it.

An oil change in a Nissan Micra automatic transmission should be carried out every 60,000 km or after repair work. This will extend the period of trouble-free operation of the transmission and the assembly as a whole.

What tools will be required

There are 2 options for replacement - full and partial. The first is performed only at service stations with a narrow specialization, because special installations are needed. Partial replacement does not require a visit to a service station. The following tools are enough:

A set of screwdrivers and wrenches.
Fitting.
Container for draining waste liquid.
Syringe to get the oil out of the factory packaging.

You also need gaskets of different diameters for the pallet and drain box.

For automatic transmission Nissan Micra and other "machines" you can not use ordinary oil. Instead, a special transmission fluid (ATF) is used. It is better to carry out the procedure in the fall - so that the car drives in the cold already with fresh oil.

How to replace: step by step instructions

Before driving a car onto a flyover or a pit, you need to warm up the oil so that it becomes liquid (it’s easier to drain). To do this, you need to “walk” the car for about an hour. It is allowed to start the procedure for replacing the technical fluid 15 minutes after the engine stops.

The sequence of work on the partial replacement of ATF in the Nissan Micra automatic transmission:

Unscrew the drain plug to drain the ATF.

Unscrew the bolts supporting the gearbox pan, remove it. They wash the magnets for collecting metal dust located at its bottom, and the Nissan Micra automatic transmission filter. If the filter is too dirty, change it.
The hose from the radiator fitting is lowered into the container, the engine is started, the liquid is drained.
Tighten the plug, pour a new ATF (volume 5.5 l) into the filler hole with a syringe. 2 liters are poured through the inlet hose.

The motor is restarted, 3.5 liters of liquid are drained. Then the same volume is poured through the hose. The procedure is repeated three times.
Put the filter and the automatic transmission pan in place, tighten the drain plug with a preliminary change of the gasket.

The oil in the automatic transmission (automatic gearbox) performs the functions of lubricating various elements, maintaining the desired temperature in the system, and a number of other functions. It is absolutely certain that the automatic transmission is one of the most important units in a modern car. It should also be noted that repairing an automatic transmission is not cheap, so you should take care of its maintenance in advance.

It is not surprising that transmission oil, like engine oil, loses its properties over time: it accumulates wear products, additives contained in the oil are produced, and in severe frost, the oil in the box can simply freeze. As a result, the gearbox can fail without a chance for repair. In general, if you do not change the oil in a timely manner and aggressively operate the car, then the consequences can be extremely serious and costly.

When to change the oil in an automatic transmission on a Nissan

The Nissan car manufacturer recommends changing the oil every 60,000 km. It often happens that a motorist does not replace after the first 60-120 thousand km., Accordingly, the next replacement is expected when crossing the mark of 180 thousand km. run, but by this time at least a quarter of the volume of oil in the system is absolutely unsuitable for work. That is why problems with the gearbox begin to arise after 200 thousand km. run.

Partial and complete oil change

There are two replacement options: partial and full. Partial replacement is when the oil is changed by means of a normal drain and refill, but at the same time only about half of the total oil volume is changed in the system, because. the rest remains in the torque converter, clutch housing and a number of other components. This can be critical for the further proper operation of the transmission.

A complete oil change is performed using special equipment. As a result, all the oil is pumped out of the system, the system is flushed and new oil is poured. It is fair to say that the replacement procedure is best done in a specialized car service.

If you decide on a partial oil change, then you will need an average of 5 liters of oil. But the frequency of partial oil changes will need to be increased so that the old used oil leaves the system (every 30 thousand km.). In the case of a complete oil change, about 10 liters will be needed.

Along with the oil, you can also change the filter, but this is not very necessary, and for various reasons, such a replacement can be extremely time-consuming. Therefore, it is better to carry out this work in a service center.

Do-it-yourself partial oil change in a Nissan automatic transmission

Let's demonstrate the process of changing the oil in an automatic transmission using the example of Nissan Maxima

1. Raise the car on a jack, or use a pit. The picture below shows the location of the transmission oil drain hole, as well as the bolts for removing the pan, under which the filter is hidden. With a partial oil change, the filter does not need to be changed, so in this case it is also not worth removing the pan.

2. Put on gloves, place a container under the drain hole where the oil will drain. Take the key to "19" and slightly unscrew the drain plug. Then completely unscrew the plug by hand. The oil will immediately begin to drain and run down your hand, which is why you need to wear gloves.

3. When the oil drains completely, it is necessary to check how many liters have drained. As we wrote above, with a partial replacement, about half of the total volume merges. To find out the volume of the drained oil, simply pour it into a bottle or some other container whose volume you know.

4. After you know how much oil has drained, remove the dipstick from the filler hole, place a funnel there and pour in the same amount of new gear oil.

5. Insert the dipstick back. Now you need to start the car and wait 5 minutes. After that, sequentially shift all gears from P to 2 and back to P. Maintain an interval between gear changes of 2-3 seconds. Then get out of the car and check the oil level with the dipstick. Top up if necessary.

This is how automatic transmission oil is changed in Nissan cars.

For a complete oil change in an automatic transmission, you should contact a service center, where the replacement will be carried out using special equipment.
