Transmission oil is intended for use in transmission units (manual gearboxes, transfer cases, driving axles).
Transmission oil performs the following functions:
— lubricates parts (bearings, oil seals, synchronizer couplings, etc.);
- creates on work surfaces gears protective film, reducing friction and preventing the formation of scuffing;
— removes wear products from rubbing surfaces;
- cools parts.
Transmission oil is classified by viscosity and performance properties.
Classification bySAEJ306(Society of Automotive Engineers - Association of Automotive Engineers, USA) defines the properties transmission oil by viscosity. This standard is internationally recognized and is used by all oil manufacturers. Transmission oils are divided into winter, summer and all-season. The viscosity of winter oil is indicated by a number with the letter W (which means winter). Viscosity winter oils defined for four classes – 70 W,75W,80W and 85W. Class 75 W allows the temperature to drop to – 40 º C.
Viscosity summer oil is marked only with a number without a letter. Classes defined 80, 85, 90, 140 and 250. The number characterizes the viscosity of the oil at temperature 100 ° C. How higher figure, the higher the viscosity.
In everyday use, it is more convenient to use all-season grades of gear oil. Viscosity grade multigrade oil is marked with an alphanumeric index consisting of two values indicating the viscosity of winter and summer oil, for example, 75 W-80.
The API classification (American Petroleum Institute - American Petroleum Institute, USA) divides gear oils into groups depending on operational indicators. This standard is also recognized internationally automotive community. Currently, there are six groups of gear oil, four of which ( GL-1,GL-2,GL-3 And GL-6) are not used in cars. Group GL-4 used in transmission units with cylindrical gear. Group GL-5 used in transmission units with hypoid transmission. Oil manufacturers in catalogs or on labels often list in detail the characteristics of components and assemblies where the use of each type of gear oil is acceptable. One should not think that oil GL-5 better than GL-4, since it is designed for heavy loads. Moreover, the use of group oil GL-5 Contraindicated in some types of gearboxes, where this disrupts the operation of synchronizers.
Transmission oils are produced that meet the requirements of both the fourth and fifth groups. The packaging of such oil is marked GL-4/5.
These classifications define generalized requirements for operational properties transmission oil. Car manufacturers conduct extensive tests when selecting oil. As a result, they choose the most suitable oils for use in the units of their cars.
Regular replacement of transmission Renault oils does not provide. The quality of produced gear oils and the perfection of transmission design modern car allows you not to change the oil in manual transmission throughout the entire service life of the unit.
Previously, we wrote about how to approach the moment and what to pay attention to. In this article we will talk in detail about how to replace a manual and automatic gearbox with a Renault Megane.
Changing the oil on a Renault Megane 2 manual gearbox
It is worth noting that changing the oil in a manual gearbox will be much easier than on an automatic counterpart, and much less transmission oil will be needed, but more on this later.
Tools
Before you start changing the oil, you need to prepare workplace and all necessary tool, namely:
- Lift or pit.
- Driver for unscrewing plugs 8.
- About 3 liters of gear oil (2.8 liters for gasoline engine, with a volume of 1.6 liters, and 2.5 liters - for a diesel analogue with a volume of 1.5 liters).
- A long hose with a funnel or a special syringe.
- Copper gasket for drain plug(article) 7703062062.
- A container for used oil with a volume of at least 3 liters.
- Pliers.
Step by step procedure
Please note that the location of these plugs is on various models may vary.
First– using a hose and a watering can, fill the oil directly from the engine side.
Second– using a syringe, fill in oil from the side of the removed wheel.
Fill the oil until its level is equal to the filling hole.
If overall volume your crankcase 2.5 liter, when filling it will fit about 2.3 – 2.4 liters of oil.
- Next, screw the drain plug back until it stops.
- We fasten the wheel and remove the wheel chocks.
- Additionally, we check all possible places for leaks and start the car.
- Checking freewheel gear knobs.
Thanks to such simple and clear steps, the oil in a Renault Megane manual gearbox can be changed within 1.5 hours.
Changing the oil in the Renault Megane 2 automatic gearbox
In order to change the oil in the automatic transmission of a Renault Megane 2 with your own hands, you will need a lot of patience and time. Since the total volume is about 6 liters of total fluid, replacement should be carried out in three stages.
The disadvantage of such a gearbox is that it does not have probes and various indicators.
To carry out all the work we will need:
- 9 liters of gear oil.
- Driver for 8.
- Container for old oil.
- Hose with funnel for filling new oil.
Step by step procedure
If the oil level is equal to or close to this value, then the total amount is normal, and the integrity of the crankcase and housing is fine.
Also pay close attention to the quality, color and smell of this used transmission fluid. If you smell a burnt smell from it, the presence of elements of plastic, metal or various grains - this will only mean one thing: the gearbox requires immediate attention. major renovation. And even the fact that the transmission does not show any complaints about its operation is not important.
- Next, tighten the plug with drain hole and move on to adding oil.
- Using a hose or syringe, pour the drained 3 liters of oil + 100-200 grams drained before into the “box”.
Then we tighten this plug and start the car.
Thus, it will be necessary to drive 15-20 kilometers and do all the work again with 1 By 7 paragraph.
After this work has been done, the replacement operation is not completed.
- Next, when you have drained 3 liters of oil for the second time, screw back the level tube that was previously unscrewed inside.
- After this, add new oil until it flows from the filler neck.
- Then we tighten all the elements, not forgetting to put on the copper gaskets and check everything for leaks.
- We start the engine and let the engine and transmission warm up.
Thus, the work on changing the oil in the transmission can be considered completed.
Results
As you can see for yourself, despite the seemingly visible inconveniences, there are no real difficulties in changing the oil on an automatic gearbox in a Renault Megane. You will need a little patience and strict adherence to our instructions.
Reference!
Such work on repeated replacement of transmission fluid in a Renault Megane automatic transmission is only due to the fact that many wear products and “dirt” particles can only go away after several procedures. Therefore, if you have the opportunity, it is easiest to replace transmission fluid at special stations Maintenance using special devices that, under the influence of pressure, “press out” the old fluid to replace the new one.
First, let's figure out what kind of oil to pour into the box of Renault Megane 2
You can select oil for the engine or gearbox on the official website -.
For Renault Megane 2:
In manual transmission - TRANSELF NFJ 75W-80
In automatic transmission - RENAULTMATIC D3 SYN or ELFMATIC G3
Gasket for the drain plug at the gearbox - 7703 062 062 ( original spare part Renault)

How much oil is in the box:
It is impossible to completely drain such a quantity.
To change or not to change the oil in the box?
According to information from Renault, like many other automakers, the oil in the gearbox is filled for the entire service life of the gearbox.
However, many owners change the oil in the box at one time or another.
Description of checking the oil level in automatic transmissions
Description of changing the oil in a manual transmission and checking the oil level
using the example of Megan 2 1.5 diesel engine
Required:
Lift/pit
Square key for 8
As we have already found out, in this engine TRANSELF NFJ 75W-80 oil is poured, respectively 3 liters of oil
Syringe or long flexible tube with funnel
Copper drain plug gasket (code 7703062062)
- container for used oil with a volume of at least 2 liters
Procedure:
We drive onto an overpass, the surface should be flat, put the handbrake on, and place underrun chocks under the rear right wheel.
Raise the car on a jack and remove the LEFT front wheel.
We look at the box from the side of the wheel arch and see a plastic plug. Unscrew it (possibly with pliers).
On different models The location of the drain/fill plugs may vary.
Use your finger to check the level of old oil in the box. If you can’t reach the fluid, then it’s worth finding out where the transmission oil goes.
We get down under the car.
Remove the boot or engine protection.
Using an “8” square, unscrew the drain plug at the bottom of the gearbox and drain the old black oil into a pre-prepared container. Additionally, you can rotate the wheel drive.
Location of drain plugs. Yellow marker - engine plug. Red - box crankcase plug.
After completely draining the old oil, replace the copper gasket on the drain plug and screw the plug into the gearbox housing.
Let's go upstairs. And pour new oil into the gearbox through the hole in the middle part of the box body. With a syringe - from the left front wheel.
If through a funnel and a long tube - from above, opening the hood.
The transmission oil level in the gearbox should be level with the filler hole.
It will not be possible to drain all the oil, but the crankcase volume (2.5 liters) will fit about 1.9-2 liters of oil, maybe a little more.
Screw on the plastic plug. From hand to stop.
We install the wheel. We lower the jack. We remove the stops.
We check the movements of the manual transmission lever while standing still.
If everything is in order, start the engine and drive off the overpass.
Renault engineers create fairly reliable cars. Even the oil used is of such high quality that there is no need to change it - it will last for the entire service life of the car. But in the case of ATP liquid, everything is not exactly as the manufacturer says. This will be confirmed by car service workers who have opened and repaired more than one Renault Megane automatic transmission and other similar models.
Experts are sure that the oil needs to be changed, and this should be done according to the regulations. Otherwise the box will simply fail. Even the most quality oil loses his specifications- it's a matter of time. There is no need to try to save money on automatic transmission fluid. Savings of 1000 rubles will result in a serious amount of money for the purchase and installation of a contract unit. Let's see how it works in the Renault Megane 2 automatic transmission, what oil should be poured, and how often it should be done.
When should you change?
In fact, the manufacturer does not indicate clear regulations and timing for replacing the working fluid in an automatic transmission. The Renault company guarantees each owner that the gearbox will operate smoothly throughout the entire service life of the car.
But most owners of Renault Megane, as well as others French cars They know that the quality of roads in our country is not high, the transmission constantly overheats, and sometimes operates in difficult modes. And it’s better not to allow this. The oil is changed as its level decreases. Experts insist that it is the oil change in the Renault Megane 2 automatic transmission that is carried out, and not topping up to the level - this is important.
About the choice
The issue of choosing oil is often relevant among owners of cars with automatic transmission. However, some manufacturers do not provide for the need to replace the ATP fluid in the machine. But experienced drivers They know that it is better to play it safe and thus prevent possible failures and breakdowns.
You can find out about which oil to choose for automatic transmissions and manual transmissions of Renault Megane 1.2 at the service station. You should follow the recommendations of specialists and fill only original working fluids.
The original transmission oil in the Megane2 automatic transmission (including Megane II 1.2) is manufactured by the Elf company. Thus, for transmissions with four stages of type DP0 and DP2, it is recommended to purchase ELF Renaultmatic D3 syn. With this oil, the mechanism will work as efficiently as possible. This liquid guarantees maximum smoothness reliable protection from wear of automatic transmission elements, increasing service life. The oil is fully compatible with all clutches used in the mechanism. The liquid provides stable characteristics for the box and prevents premature wear.
Manual transmission oil
Also, not all owners know what to put in a manual transmission. Experts recommend Elf transmission oils. Tranself NFJ 75W80 is suitable for Megan. This is a synthetic product that can provide the transmission with reliable protection against scuffing under high loads.
Due to the special formula for using this brand in manual transmissions, Renault Megane makes switching easier. Excellent fluidity of oils in this series even at low temperatures allows you to improve the efficiency of gears in winter cold.
How much oil does it take to change?
For manual transmissions on petrol power units you need approximately 2.8 liters of gear oil. For manual transmissions With diesel engine you need less - about 2.5 liters. To change the oil in a Renault Megane 2 automatic transmission, you need 6 liters of transmission fluid. But due to the design features, only 3-3.5 liters can be filled.
How to check the level?
How to check the transmission fluid level in an automatic transmission? All work is divided into several stages.
So, the first thing you need to do is find a flat area. Then you should connect the diagnostic adapter, start the engine and let it run at Idling. Next they come into contact with the car’s electronics - using the device you need to monitor the temperature of the oil in the automatic transmission. You need to wait until the temperature rises to 60 degrees. Then the control plug is unscrewed on the automatic transmission body. Changing the oil and checking the level in the Renault Megane box is carried out using this plug.
The fluid level is normal if the plug is “wet”. When it is dry, you need to stop the engine and add fluid through the fill hole. After this, it should take a little time for the temperature to drop to 50 degrees. Next, start the engine again and wait until the temperature rises to 60 degrees.
Unscrew the plug and check the level. If oil drips from the inspection hole during the check, then its volume is sufficient.
Changing the oil in the Renault Megane 2 automatic transmission: instructions
How is the work process carried out? The sequence of actions for changing the oil in a Renault Megane 2 automatic transmission is the same as for changing the oil in the engine. First merges old fluid, and then a new one is poured. These automatic transmissions also have oil filter. But it is impossible to remove it without dismantling the gearbox. There is no dipstick in the automatic transmission of the French Megane, and out of 6 liters of oil, only 3.5 can be replaced. Therefore, the operation should be performed in several approaches. You will need a little more oil - 9 liters.
We merge the old one
At the bottom, as well as at the top of the automatic transmission, there is a drain, as well as filler plug. The first one goes under a tetrahedral key. It must be purchased separately from the market. It is necessary to unscrew the plug and drain the old oil. First place an empty 4-liter container. At first, the amount of liquid drained will be small - up to 400 grams. There is a hex level tube inside the drain hole. It is carefully unscrewed, and when it is unscrewed as much as possible, 3 liters of ATP liquid will drain out. It is worth paying attention to the smell and color of the oil. If the fluid is dark, it means it has not been replaced for a long time. The presence of foreign objects indicates increased wear clutches in automatic transmission.
Note: at this moment the car should be in “Parking” mode.
Uploading something new
How is the oil changed in the Renault Megane 2 automatic transmission? At the next stage, you need to tighten the drain plug and unscrew exactly the same one, but from above. The plug is unscrewed and lifted up. It has a copper sealing ring- It’s important not to lose it. Otherwise there will be liquid leaks. Next, using a filler syringe or any other means, pour the volume of oil that was drained into the filler hole and add another 150-200 g.
Then after pouring fresh oil start the engine. Keep the car on the brake and switch to all positions. Then you should drive about 20 kilometers by car.
How to completely replace the fluid?
To execute complete replacement oil in automatic transmission and manual transmission on Renault Megane, you need to repeat the above procedure one more time. Place an empty container under the plug and drain working fluid. After this, 3 liters of oil should remain in the gearbox. When it has been drained a second time, the level tube is screwed into the drain hole and oil is poured into the filler hole until it flows from below.
Then they start the car in the parking lot and top it up until it starts leaking again. Next, tighten the drain plug and filler plug. Next you need to drive 15-20 kilometers. After this you can check the level. If oil flows after unscrewing the drain plug, then everything is in order. If not, you need to add to the required amount.
About the filter
How to remove the oil filter in a DP0 automatic transmission on a Renault Megane? Most owners do not resort to this procedure because cleaning element located in the box itself. To remove the filter, you need to disassemble the entire transmission.
With your own hands this procedure impossible to do. Therefore, gearbox maintenance is limited only to replacing the ATP fluid, without installing a new filter.
Finally
So, we found out how to replace ATP fluid on a Renault Megane car. As you can see, you can perform the procedure yourself. However, due to the special location of the filter, you cannot replace it yourself. On other cars, this element is located in the tray and can be in the form of a mesh or magnet.
Renault Megane has been produced since 1995. There are four generations of the model, the cars were equipped with gasoline atmospheric engines with a volume of 1.4 - 2.0 liters, turbocharged engines with a volume of 1.2 - 2.0 liters and diesel engines with a volume of 1.5 to 2.0 liters. Transmissions used on Megane various types, including 5- and 6-speed manual transmissions, 4-speed automatic transmissions, CVTs and EDC robotic transmissions.
