Hello, dear readers! Today I will tell you about changing the oil in the automatic transmission of a FR car. The manufacturer of the gearboxes that Mazda 6 is equipped with guarantees excellent operation using the same automatic transmission oil until the end of the automatic transmission’s service life. However, I do not recommend taking the manufacturer's word for it. Firstly, the climatic operating conditions are different, secondly, the roads and, thirdly, the driving style of the drivers.
Write in the comments, do you follow the manufacturer's advice or listen to our experienced mechanics?
Transmission oil change interval
Now let's talk about the oil change interval in the Mazda 6GH automatic transmission. I recommend changing the transmission fluid after a certain number of kilometers, in addition to changing the oil in an automatic transmission during a scheduled repair of the automatic transmission drive.
I recommend changing the oil according to the following schedule:
- 30,000 kilometers – partial change of transmission fluid in the Mazda 6 automatic transmission;
- 60 thousand kilometers - complete change of lubricant in the machine.
The fact is that the technical properties of the oil are greatly affected by overheating and cold starts in winter. Parameters quickly change if the fluid is neglected, and the oil can no longer properly protect mechanical parts from wear. Mazda 6 automatic transmissions do not like poor lubrication.

The filter device is clogged. The pressure in the machine drops. The automatic transmission begins to push and kick. By the way, driving an automatic transmission with bad oil for too long can lead to engine repair. Since these two units are interconnected. If one does not work well, it will pull the second one after it.
Attention! Many car owners think that they can go without changing the lubricant for years, hundreds of thousands of kilometers. Then, when it becomes impossible to drive an automatic, they come to a car service center and ask for an oil change. We change their oil. After some time, the automatic transmission of the Mazda 6 fails, and they blame it on the oil change. So, dear car owners, a breakdown of your gearbox means only one thing: you replaced the lubricant too late.
And also do not forget that you need to buy oil, if you change it yourself, in specialized stores. They may sell you counterfeit goods at the market. A counterfeit lubricant can be a step towards a major overhaul of the Mazda 6 automatic transmission.
The best motor oil. does it exist?
In addition, there are other factors by which you can determine the need for an oil change. Let's look at them point by point:
- When checking the level, it was discovered that the oil was dark in color and smelled burnt.
- The dipstick shows an insufficient fluid level - in this case, adding new oil will be enough if the signs specified in paragraph 1 are detected. Otherwise, a complete fluid change may be required, during which the old fluid is first drained, then the gearbox is washed, and only after this introduces a new transmission composition
- The gearbox engages with effort, there may be delays when shifting
- Increased fuel consumption
- Engine power drop
- Oil leaks at the gearbox caused by a clogged oil filter
- Engine traction periodically disappears when driving uphill
Practical advice on choosing oil in an automatic transmission Mazda 6
You may ask what kind of oil should be poured into the Mazda 6 GJ automatic transmission, and why not others. I will answer. The fact is that the lubricant from the manufacturer of the Mazda 6 automatic transmission has technical properties designed only for the operation of this automatic transmission. For example, viscosity. If the transmission fluid is thin, the automatic transmission will overheat. If it is too viscous, then it will not be able to get into hard-to-reach components, the pressure will disappear, you will feel jerks and jolts when switching gears, and the mechanical parts will quickly wear out.

Some counterfeits can ignite at temperatures just above 100 degrees. You don’t want your Mazda 6 automatic transmission to burn out due to counterfeit goods?
Original oil
The original oil that is poured into the box is called Mazda ATF M V. It provides controlled sliding for friction units. Has a low pour point. Does not form foam unless mixed with analogues.
ATF MV has a high viscosity index. This allows the vehicle's mechanical parts to operate in difficult and harsh climatic conditions. Transmission fluid tolerates frost well in northern latitudes.
Attention! In winter, be sure to warm up the Mazda 6 automatic transmission. Do not start abruptly and do not drive the car aggressively.
Analogs
The original described above for the Mazda 6 automatic has similar fluids that are recommended to be used if you cannot find ATF MV in your city. These include:
- Toyota Type T IV;
- Dexron IV;
- Ford Mercon V.
These fluids are cheaper than the original oil. But their properties are similar. Only when filling in this type of lubricant, so that the liquid does not foam, make a complete replacement using the substitution method.
Attention! A complete replacement of lubricant at a service center costs RUB 2,000.
Causes and signs of failure, diagnostics
The main functions of the oil used in the transmission system are:
- Formation of a durable film on the surface of parts, which prevents wear of components and mechanisms.
- Removing heat from heating elements.
- Corrosion protection.
- Reduced shock loads on gears.
As a rule, the replacement frequency established by the manufacturer is quite arbitrary and is designed for ideal vehicle operating conditions. The poor quality of domestic roads, a large amount of dust and dirt, reagents in winter, too harsh driving, as well as harsh climatic conditions and untimely maintenance can lead to the fact that the transmission oil will have to be replaced much earlier than the period specified in the regulations. This is due to the fact that, under the influence of these factors, it begins to lose its basic properties, and cannot cope so effectively with the transmission of torque and its other functions.
Checking the level
This machine has a dipstick. Therefore, the level checking procedure is simplified. No need to crawl under the car and get dirty in oil. The steps for the level checking process are as follows:
- Warm up the automatic transmission to 70 degrees.
- Press the brake pedal and move the selector lever through all gears.
- Place the Mazda 6 on a flat surface.
- Turn off the engine and open the hood of the Mazda 6.
- Unscrew the plug with the dipstick.
- Wipe the tip with a lint-free cloth, preferably white.
- Insert the dipstick into the hole and rotate it 180 degrees.
- Take it out and look at the risks.
- If the oil reaches about 0, then everything is fine with the level. If it's lower, add more.

Wipe the dipstick with a white rag again and look at the color. If the color of the lubricant is light, then the oil is fine. If the transmission fluid has darkened, it needs to be changed.
Preparation
So, before deciding which replacement method to choose, you need to check the level and condition of the oil in the gearbox. To do this we do the following:
- Drive a little to warm up the box, leave the engine on
- The vehicle must be parked on level ground
- Find the drain plug in the engine compartment, unscrew it, then remove the dipstick and wipe it with a towel, then reinsert it into the hole. Then pull it out again to look at the fluid level, and at the same time pay attention to its color
- The optimal fluid level is considered to be the oil mark between the Max and Min marks on the dipstick. If the level is below the Min mark, then you need to add oil. But it is important to remember that if the liquid stinks and is black in color, it needs to be completely measured, even if the level is sufficient.

Carefully remove it and drain the remaining liquid into a container. Do the work wearing gloves. Because the liquid may be hot and will damage the skin of your hands.
Washing the tray and removing chips
The box tray is washed with carbocleaner or kerosene. Remove the magnets and clean them of chips that have accumulated during operation.
Carefully remove the old gasket with a sharp object. Degrease this area and put a new gasket on it.
Now proceed to replacing the filter device in the box.
Replacing the filter
The oil filter is replaced after removing the Mazda 6 pan. Unscrew the bolts that hold it in place and remove it. Be careful, there may also be some liquid left in it. Drain it into a container.
Throw away the old filter. Do not wash it or reinstall it. This procedure will not have any effect.
After installing the new filter device, lubricate the pan with sealant and attach it to the automatic transmission. Tighten the bolts. Tighten the drain plug on the Mazda 6. Now you can start filling in new oil.
Filling with new oil
Fresh fluid is added through the filler hole under the hood. Open it up and remove the air filter to open up more space to access the filler hole.
Insert a funnel and start pouring oil into the automatic transmission. You will need about 4 liters of lubricant. Then you will need to install all the parts in the reverse order and close the hood.
Start the car, warm up the Mazda 6 automatic transmission and drive it for 10 kilometers. Check the level.
