Changing the oil in a Renault Logan manual and automatic transmission

Why change transmission fluid?

Like any other lubricant, the composition for manual and automatic transmissions performs a number of important functions:

Extends the service life of the unit. During friction of parts, wear will be inevitable, but oil improves the sliding of gears and increases the service life of all components.
Cleansing. When the gearbox operates, metal shavings are generated, which in large quantities can pose a danger to the gearbox. One of the functions of the oil is to carry these chips to a collection area where the magnet is usually installed.
Structural protection. The metal is susceptible to corrosion. To prevent oxidative reactions, the oil creates a film on the surfaces of parts.
Reducing noise and vibration from gearbox operation, heat removal, reducing shock loads during switching.

Thus, transmission oil is an essential component, without which the operation of the gearbox will be impossible.

Another question is whether replacement is necessary, because many automakers claim that the transmission fluid resource is enough for the entire life of the car. Let's figure this out. It’s worth starting with the fact that the maximum shelf life of liquid in packaging is 5 years. Now imagine that the oil is actively used in the gearbox and gradually becomes contaminated with shavings and other small particles. Naturally, talking about unlimited service life is very stupid, especially if you actively drive your car.

Why do manufacturers then make such statements? It’s all very simple. It's about marketing. If the driver changes the transmission fluid on his own, the gearbox will not break down and the automaker will be left without additional income. The sale of spare parts for a car is a significant share of profit, so it is beneficial for companies that the car owner contacts branded technical centers for repairs and maintenance as often as possible.

When to change the oil in Logan's gearbox?

According to the manufacturer's recommendations, the fluid in the Renault Logan gearbox is replaced every 60 thousand kilometers. Depending on the operation, the replacement schedule can reach up to 100 thousand kilometers, or vice versa, decrease down to 30-20 thousand. In this regard, it is necessary to regularly monitor the level and quality of the oil using a dipstick. In addition, premature wear of various components and assemblies, such as the clutch, cannot be ruled out. The fact is that repairing one of the transmission units will entail an oil change. Therefore, it is also necessary to monitor not only the condition of the oil, but also the condition of, for example, the CV joint boots and clutch.

Deciding on frequency

As mentioned earlier, the manufacturer does not make any recommendations regarding changing transmission oil and does not even recommend this operation. Auto mechanics are of the opinion that Renault Logan manual transmission oil should be changed every 100-120 thousand kilometers. These are arbitrary numbers, since the fluid may become unusable even earlier if the gearbox was operated under extreme conditions.

An automatic transmission is much more complex in its design. Oil changes in Renault Logan automatic transmissions occur more often (approximately every 50-60 thousand kilometers). It is not recommended to exceed the presented values. Neglecting to replace transmission fluid will result in accelerated wear of parts and the need to replace them. In the most critical situations, the box can completely jam. In this case, you cannot drive a car, so you will have to call a tow truck and go to the nearest service station.

Some points of the theory

During intensive vehicle operation, gearbox elements are subject to constant wear, accompanied by the accumulation of metal shavings in the crankcase of the unit. Its appearance is caused by continuous abrasion of the mating surfaces of the gears. To collect chips, there is a special magnet located in the tray of the box.

How to check the oil? To determine the appropriate type of gear oil and check its tolerances for Renault Logan, please refer to the reference book.

Engines with a volume of 1.4 liters were produced complete with different transmissions, for which the volume of lubricant has different values (depending on: automatic or manual). It is necessary to pay attention to the viscosity of the fluids used, since pouring oil with other viscosity parameters will lead to premature wear of the gears and failure of the unit. Changing the oil in the gearbox is a crucial moment. To ensure that the required level is filled, use a syringe to pump oil into the box. It is also recommended to inspect the unit for leaks.

Signs of wear

It is necessary to rely only partially on mileage values, since fluid wear depends on individual driving habits and the condition of the transmission. We recommend studying the main symptoms that will tell you when to fill in new gear oil:

the appearance of loud extraneous noise, especially when operating in neutral gear;
Difficulty in shifting gears;
“sluggish” operation of the switching mechanisms, which is especially noticeable in automatic transmissions;
the appearance of vibrations or beating in the shift handle;
the appearance of a burning smell.

All this may indicate a breakdown of any part of the assembly. However, first of all, start by changing the oil, and only then carry out detailed diagnostics.

How to change the oil in a Logan automatic transmission

If the oil has reached the end of its service life, it will not be able to perform its intended functions. This means that the substance is not able to properly lubricate the rubbing components of the unit. This leads to rapid wear of parts.

The first to fail are the bearings, the failure of which can be indicated by symptoms such as noise and hum in the operation of the gearbox. Sometimes sounds appear when you turn on a certain gear. It is also possible for the speeds to switch off spontaneously. If you do not take immediate action to change the oil, the entire gearbox will fail.

Types of oils

All products are divided into several groups (depending on the base used). There are mineral and synthetic transmission fluids. The former are most often used on older cars, where the gearbox has a lot of wear. Mineral compositions are the cheapest, have a relatively short service life, and to increase their anti-corrosion and leaching properties, all kinds of additives are added to them.

The gearboxes of modern cars are filled with synthetic (less often semi-synthetic) oil. It has the best performance qualities: long service life, preservation of viscosity indicators over a wide temperature range and effective protection against corrosion.

Additionally, we recommend paying attention to the markings according to the SAE standard. It shows in what temperature range the oil retains its viscosity characteristics. Typically, cars are filled with all-season models, which are designated as two numbers separated by the letter W, for example, 75W80. Using these numbers, based on special tables, you can determine the maximum and minimum operating temperature of the composition. If you are looking for analogues, then check that the SAE marking is similar to the original.

What to look for when changing the oil

The durability of the gearbox depends on the quality of the fluid. The main thing in choosing oil for a Logan gearbox is not to go cheap and not choose an inexpensive mineral one. It is characterized by instability. Semi-synthetic and synthetic are much better suited for Logan's gearbox.

However, you should not mix different types of transmission fluid. For example, add semi-synthetics to synthetics. Or mix, for example, Elf and Motul, wanting to save money.

Some additives may precipitate and affect the operation of the gearbox gears. As the viscosity of the oil increases, it may clot and the gearbox will stop working. Therefore, it is better to choose one oil and stick to it in the future. If the manufacturer suddenly stops producing it, the oil should be replaced completely.

What oil to use

Let's move on to specifics and find out what kind of oil to pour into the Renault Logan box. Let us remind you that cars are produced with two gearboxes: automatic and manual. For manual transmissions, the automaker recommends a product called Elf Tranself NFJ 75w-80. This is a high-quality product, so it is recommended to fill only the original. You will need about 3.5 liters, but it is best to buy 4 liters with a reserve. If you choose analogues, make sure that the composition meets the API GL-4 quality class and has a similar SAE marking.

For the automatic transmission, ELF RENAULTMATIC D3 is used (catalog number 194754). The oil volume in the Renault Logan gearbox is up to 3 liters. The cost of this product varies depending on the region, but on average it is 500 rubles. As an analogue, you can look for Castrol Syntrans Transaxle 75W-90 or MOTUL Gear 300 75W-90, but drivers recommend using only branded products recommended by Renault itself.

Please note that using a composition with characteristics that differ from those required will lead to disruption of the gearbox. For example, too high a viscosity will make gears difficult to function. As a result of this, the box will operate under increased loads. Once you have decided how much oil needs to be poured into the Renault Logan gearbox and have bought everything you need, you can start replacing it.

Be careful, because there are a huge number of fake branded formulations sold on the market. They do not have the characteristics of the original, but they can cost the same. Here it is important to pay attention to the packaging, its shape, color, quality of label printing and the presence of any defects.

The choice of the plant or the choice of the people!?

The manufacturer, for replacement in a manual transmission (MTF marking), recommends branded transmission oil: ELF Tranself NFJ 75W80 (semi-synthetic), 75 W90 (synthetic), (the price for 1 liter today is within 600 rubles). The required volume for replacement is 3.5 liters.

Official dealers recommend this particular oil for automatic transmissions. And this is not surprising, this is Elf

According to the manual from the factory, the automatic transmission should be filled with ELF Renaultmatic D3 Syn, which will take about 4 liters for a complete replacement .

Experienced “Loganovods”, through personal trial and error in changing transmission oil, identify leaders whose quality and technical properties are in no way inferior to those recommended from the Renault plant.

Despite all of the above, fans of Renault Logan cars note that it is an obvious outsider and do not recommend replacing it with SHELL Getriebeoil EP 75w90 GL4 . Judging by the dissatisfied statements, the manual transmission in tandem with gear oil from this manufacturer begins to behave like a worried stallion. In almost all cases, there is a hum, crunching and noise from the gearbox.

Preparatory activities

Regardless of your transmission type, you will definitely need to prepare a minimum set of tools. It includes:

set of socket wrenches;
special four-sided key 8 by 8 millimeters;
pliers;
metal brush;
a funnel made from a regular plastic bottle and a hose with a cross-section for the filler hole;
containers for used oil (volume is selected depending on the gearbox);
flashlight or other lighting.

The drain hole is located in the bottom area, so it is most convenient to carry out work in a pit or using a lift. The most extreme option is to raise the front part with a jack, but in this case there will not be enough free space. Be sure to wear protective clothing, since transmission oil can be difficult to wash off.

Auto mechanics also recommend carrying out work on a warm engine. The temperature in the box should be 55-60 degrees. This will ensure better fluidity of the composition, but in this case, use mittens. The plug and the oil itself will be quite hot.

Replacing transmission fluid in a Logan manual transmission

Most Logan cars have a manual transmission, so let's look at the process for that:

To make work easier, remove the engine protection. It is secured with several bolts.
Locate the drain hole. It is located on the side of the engine oil drain hole. Place an empty container. Using an 8x8 wrench, unscrew the cap.
Once all the oil has been drained, use pliers to unscrew the filler plug. It is located a little closer to the front bumper relative to the previous hole. Positioned horizontally.
Tighten the drain hole, it is advisable to replace the gasket.
Pass a hose through the engine compartment and insert its end into the oil fill hole.
Start pouring the new mixture into the funnel. Fill until liquid begins to flow out of the drain hole in a thin stream. Please note that the machine must be on a completely level surface.
As soon as the thin stream stops running, screw the lids on.

This completes the process. Checking the oil level in the Renault Logan gearbox is carried out exactly at the filler hole. It is also often called control.

Replacing transmission fluid in a Logan automatic transmission

There are no fundamental differences in changing the oil for automatic transmissions in Renault Logan cars. It is necessary similarly:

Remove the protective panel under the bottom, unscrew the drain plug and drain the used transmission fluid.
Approximately 1.8-2 liters will drain. Then the level flask located nearby is unscrewed.
Wait until more liquid flows out of it, and then unscrew this part with a 8-mm hexagon. By completely removing the plastic flask, you can drain the remaining oil. A total of about 3.5 liters should come out.
Replace the level flask and plug. Don't over-tighten them.
In the engine compartment, find the filler hole, next to the air duct, which will have to be removed. Add the required amount of new transmission oil.
Start the car and warm it up to 90 degrees. Click all gears (D, N, R, P). At the end, set the position P - “parking”.
With the car running, unscrew the drain hole. 100-300 milliliters of liquid should flow out of it. As soon as it starts to drip slowly from the hole, screw the cap back into place.
Next, you need to add oil to the Renault Logan box (approximately half of the drained volume of liquid). If 0.5 liters leak out, then add 0.25 liters.
Tighten the filler plug and put all components in place (air duct, crankcase protection).

Thus, changing the Renault Logan automatic transmission oil is a little more complicated, since the work has to be done in several stages. It is very important to warm up the engine. Without special stands, mechanics advise warming up the engine to 90 degrees and starting replacing it in a couple of minutes. The whole process will take you about 1 hour. Finally, be sure to take it for a test drive. Make sure that the problems with the gearbox have disappeared, and the unit has become quieter and gear shifts have become softer.

This is a partial replacement procedure. It will be impossible to completely change all the oil yourself in a garage, but in this way you change 3-4 out of 6 liters, so the unit will work with high-quality lubrication.

A lack of transmission fluid in an automatic transmission is dangerous because the pump will begin to swallow air. Such a mixture has different characteristics from oil, and therefore is not able to ensure normal operation of the gearbox. The result is regular overheating and wear of the assembly parts. Considering the high cost of automation on Logan, it is in the driver’s interests to achieve the longest possible service life.

DIY oil change

You can replace the lubricant in Renault or Dacia Logan at a service station or yourself. Let's look at how to change the product yourself.

To change the lubricant, prepare:

an old bucket or basin, this container will be used to collect waste liquid;
new oil;
wrenches 8 and 10;
transparent hose with watering can.

Stages of work

The procedure for draining and filling grease is as follows:

The car warms up and is driven into a garage with a pit.
You need to crawl under the bottom of the car and unscrew the bolts that secure the engine protection. This will make changing the oil easier.
It is necessary to find the drain plug and place a container under it to collect the waste.
Then you should unscrew the bolt and wait until all the oil comes out of the gearbox. Then assess the condition of the drain plug and its seal, which must be replaced as it wears out quickly.
You need to find a hole to control the level. Then insert one end of the prepared hose into it, and connect the watering can to the other. You can begin the liquid filling procedure. This is done until the oil begins to come out of the inspection hole. The amount of lubricant to be filled depends on the type of transmission.
Use a rag to remove any remaining substance from the gearbox housing. Screw on the filler cap.
It is necessary to reinstall the power unit protection and clean the transmission breather.
