To ensure proper operation of the transmission in the Mitsubishi ASX, car owners are advised to check the oil level in a timely manner. Timely replacement will help avoid engine breakdowns and extend the life of the vehicle.
When is it necessary to change the oil in the variator?
Manufacturers of the Mitsubishi ASX do not recommend changing the oil in the variator throughout the entire life of the vehicle. One auto mechanic disagrees with this statement and recommends carrying out the replacement process every 50 thousand km.
Factors affecting oil change frequency:
- Temperature indicators outside (presence of above-zero or below-zero weather).
- Availability of a trailer and frequency of its use.
- Operating conditions of the vehicle.
Replacing transmission fluid is carried out in two ways:
- Partial change. When choosing this method, the car owner must update the oil every 500 km.
- One-time. This method involves draining the old fluid and filling in a new one in the same quantity. A one-time replacement is considered ineffective.
What oil should I use?
When choosing an oil fluid to replace, the car owner must choose only between original oil options.
Available oil options:
- Mitsubishi Dia Queen CVT Fluid J1;
- NISSAN NS2;
- Mitasu CVT;
- Nissan CVT Fluid NS.
The oil fluid for the Mitsubishi ASX variator is green in color and must meet the specifications declared by the manufacturer.
Stages of work
When changing the oil in a Mitsubishi ASX variator yourself, it is recommended to use the double-flushing method. It includes the following steps:
- draining waste material;
- bay of new;
- start the engine for 5-10 minutes and carry out the above steps again;
- cleaning magnets and tray;
- mileage reset using the chipping method.

The process of changing the oil in the Mitsubisi ASX variator is complete.
Starting the engine after changing the oil in the variator
After the car owner has filled in the required amount of fluid, he must reset the CVT oil degradation level. This procedure is necessary for the pump to pump excess pressure.
Then the engine starts and the gears are changed for 5 seconds each. The last step is to check the oil level after stopping the engine. If it reaches the maximum level, then the replacement was successful.
Consequences of untimely replacement
With timely monitoring of the oil level in the variator, its service life increases significantly and can reach 300 thousand km. If the leak is not detected in time, the following car breakdowns are possible:
- transmission failure;
- increased fuel consumption during vehicle operation;
- wear of automatic transmission components.
Until 2014, Mitsubishi ASX manufacturers produced cars without a radiator, which reduced the life of the variator. There are no indications in the vehicle about the failure of the variator, so owners of Mitsubishi cars are recommended to check the oil level themselves.
Today in the article we will look at how to change the oil in a Mitsubishi ASX variator.
For example, let's take a car manufactured in 2010 with a mileage of 80,000 km. The manufacturer recommends changing the oil in the variator every 75-80 thousand kilometers of the car. The amount of oil in the Mitsubishi ASX variator is 7.1 liters.
Spare parts for changing the oil in the ASX variator
To change the oil in the variator you will need:
7.1 liters of oil (for partial replacement)
CVT pan gasket - part number 2705A015
Coarse filter (if necessary) - catalog number 2824A007
Fine filter (in the heat exchanger) - catalog number 2824A006
Heat exchanger gasket - part number 2920A096
Drain plug gasket - part number 2705A013
O-ring for coarse filter - part number 2824A005
Oil change work in a Mitsubishi ASX variator
Having placed the car on a lift or inspection hole, it is necessary to remove the engine protection and the front left fender liner to gain access to the heat exchanger and radiator (if it is included in the package).
Raise the car, unscrew the drain bolt and drain the oil into a container prepared in advance. About 5 liters of oil are drained.
It is advisable to remove any remaining oil from the pan using a syringe with a tube, because... About 500 grams of oil remain in it and when the pan is removed, everything flows into the hands of the master.
We remove the pan and wash it from dirt, while not forgetting to wash the magnets that are installed in the pan to retain metal shavings.
We unscrew and change the coarse oil filter in the variator.
Remove the heat exchanger cover and change the fine filter and sealing ring.
We install a new pan gasket and screw the pan into place.
Fill in new oil using a funnel through the dipstick hole.
Warm up the car at idle for about 2 minutes, while sequentially switching the variator control selector to all positions and returning to “P” or “N”.
After turning off the engine, drain a small amount of oil through the pan into a transparent container. Compare the color of the drained oil with the new one; if it is contaminated, drain it completely and fill it with new one.
If the oil is not contaminated, then add oil to the level, warm up the car engine to operating temperature (up to 2 cooling fan activations).
Set the oil level in the variator within the “HOT” mark on the dipstick.
Also, do not forget about resetting the service interval parameter.
Variators (CVT) of Japanese origin enjoy authority. CVT is installed on European and American cars. With each new car model, the CVT takes the place of classic manual transmissions and automatic transmissions.
Cars equipped with a CVT differ from cars with a manual gearbox in their smoother running and comfort, and from the automatic version in reliability and efficiency. According to the manufacturers, the variator, if simple recommendations are followed, can be used for a very long time. In addition, it does not require as much servicing as automatic and manual transmissions. The durability of this unit directly depends on how carefully the driver treats it.
According to the scheduled maintenance recommended by the manufacturers, the oil change in the ASX variator in the first models produced since 2010 should be carried out upon reaching 90 thousand km. A little later, this figure was reduced to 75 thousand km. CVTs use a special oil composition.
The fluid is formulated to withstand high transmission pressures and the special metal alloy used to make the internal components of the CVT. In addition, it should prevent the metal belt from slipping between the pulleys of the device.
The characteristics of oil for filling into the variator on a Mitsubishi ASX must correspond to those recommended by the manufacturer. CVT oil is green. The choice of manufacturer can be at the discretion of drivers, the main thing is that it is original and meets the tolerances. You can use Mitsubishi Dia Queen CVT Fluid J1, NISSAN NS2, Mitasu CVT or Nissan CVT Fluid NS oil, etc.
There is an opinion that the oil in CVTs does not require replacement at all. Until the mileage is 150,000 and 200,000 km, you don’t have to look at the transmission at all. But even manufacturers cannot give an unambiguous answer when changing the oil in a variator, because the operating conditions of the car are different.
The frequency of oil changes depends on:
- ambient temperature (minus or plus);
- is there a load in the form of a tow hitch and how often is it used;
- car operating mode.
Changing the oil in the variator can be done in several ways:
- partial replacement. In this case, a certain amount of liquid is drained 4-5 times every 500 km. In this case, the oil is updated.
- a one-time replacement, when the old fluid is drained and the same amount of fresh oil is added. This method is not effective, since a certain volume of old fluid remains in the lines.
Changing the oil in the Mitsubishi ASX variator is recommended according to the double-flushing principle. After the liquid is completely drained, new oil is poured in, then you need to turn on the engine for 5-10 minutes, after which it is drained again and refilled. It is also necessary to dismantle the tray to clean the magnets from dirt and change the filter. The final stage is zeroing the mileage using the chipping method.
Do-it-yourself oil change in a Mitsubishi ASX variator
In order to change the fluid in the ASX variator you need to:
In cars produced before 2014, a radiator was not installed on CVTs. Structurally, this modification allows you to significantly increase the service life of the variator, and therefore increase the service life of the oil. With timely replacement of the variator oil and filters, the transmission guarantees a mileage of 300,000 km without repair.
The Mitsubishi ASX does not have a display indicating a malfunction or emergency operation of the CVT, so it is necessary to monitor the mileage and prevent untimely oil and filter changes.
A Mitsubishi ASX car came to us for service, with a 1.8 liter engine, manufactured in 2013, front-wheel drive, mileage 202 thousand km. It is necessary to change the oil in the variator, in addition to this, we will replace the heat exchanger filter and the variator itself. After looking at this photo and video instructions, you can repeat everything yourself in a garage.
The process of changing the oil in a Mitsubishi ASX variator
The owner’s variator began to behave a little problematically; it has a “tightening” when engaging gears. If you put it in gear and give it gas, it hits. The first oil change was performed at 130 thousand km. mileage For today's change, 8.8 liters of new oil were purchased CVT Fluid J4 article number for ordering MZ320185.
Let's get to work, lift the car, dismantle the left front wheel. We take out the clips and remove the wheel boot. We place the waste oil container down and unscrew the drain plug using the 19mm head:
Our glass is about 4 liters. Then screw the plug back into place. Take a funnel with a spout, insert it into the hole for the dipstick and fill in 3 liters of new oil:
You can start the engine without pulling out the funnel. With the car stationary, hold the brake pedal, turn on each gear alternately and hold it for 10-15 seconds. We turn off the engine. We climb under the car again and unscrew the drain plug, draining the filled oil. After the oil has drained, we begin to unscrew the pan, we do this using a 10mm socket.
Use a 10mm head to unscrew the variator filter:
While the last drops are draining from the variator, we move on to the heat exchanger. Using a 10mm socket, unscrew the 4 bolts that secure it:
You may need a flexible extension to get to the top two bolts. We move the heat exchanger to the side, using long clamps we take out its filter:
When removing the filter, pay attention to its rubber band; if it is not removed along with the filter element, it means it remains in the car, be sure to remove it.
The new filter immediately comes with a new o-ring. We install a new heat exchanger filter, the original one, its order number 2824A006. It is very easy to install by hand:
We move on to replacing the heat exchanger gasket, we have a new one, original from Mitsubishi, order number 2920A096. We dismantle the old one using a flat screwdriver:
Take carburetor cleaner and wash the groove, then wipe it dry. Install a new rubber ring into the groove. Carefully place the heat exchanger in place and tighten the bolts.
We return to the variator, install a new filter on it, we have it from Asakashi reviews, order number JT406K. Included with the filter is a new rubber-cork pan gasket, but we will not install it, we pre-ordered the original one, its number for purchase 2705A096. If you have a torque wrench, then you need to tighten the fastening bolts with a force of 9 N-m.
Before installing a new pan gasket, wash off any remaining oil using carburetor cleaner, then wipe it dry with a clean cloth. We also thoroughly clean the tray and magnets. We put the gasket on the pallet and attach it. The gasket and tray have guides on the sides. We tighten the pan bolts with a force of 9 N-m. The original gasket is profiled, it holds perfectly, does not sweat, there is no need to coat it with sealant.
We lower the car and safely fill in 4 liters of new oil for the variator. We start the engine, make sure there are no leaks underneath, warm it up to operating temperature and set the level. In our case, we had to add even more liter.
Video changing the oil in a Mitsubishi ACX variator
Part 2 of the video on how to change the oil in a Mitsubishi ASX 1.8 variator:
Mitsubishi ASX is not the most popular crossover on the Russian market. However, without a doubt, this is one of the most reliable models among its competitors. Stylish, discreet design, thoughtful interior and good driving performance – an excellent family station wagon with the makings of an SUV. The car is in stable demand. Among the owners of supported copies, there are those who prefer to maintain ASX on their own. The possibility of independently repairing a Mitsubishi ASX is quite justified, especially considering the reluctance of owners to use the services of an expensive Mitsubishi dealership. One of the most common self-service procedures is changing the gearbox oil. In this article we will look at how to properly change transmission oil using the example of a Mitsubishi ASX with a 1.8-liter engine and a CVT.
Which oil to choose
It is recommended to fill only high-quality original oil that meets certain parameters specified in the instructions for the machine. In particular, it is preferable to use the following options: Mitsubishi Dia Queen CVT Fluid J1, Nissan NS2, as well as Mitasu CVT and Nissan CVT Fluid NS.
When to fill
It is recommended to change transmission oil for Mitsubishi ASX every 200 thousand kilometers, according to official data. But on the other hand, there is no need to take this figure into account if the car is operated in difficult climatic and road conditions. Thus, in Russia the recommended oil change interval reaches 30-40 thousand kilometers. But we must admit that this is also an ambiguous figure, because the frequency of changing the fluid in the gearbox depends on many factors:
- temperature outside the car
- vehicle load level
- operating mode and driving style
Types of oil changes
Partial - when the fluid is replaced without using flushing oil. In this case, oil is added 4-5 times every 500 kilometers. Thus, the oil is gradually renewed
One-time - a one-time fluid change, carried out in compliance with all procedures, including the use of fresh oil. Considered less effective than partial replacement
How to change the oil in a Mitsubishi ASX variator
Sequence of work:
- Place the car on the viewing platform. Alternatively, a pit or overpass will do
- Warm up the engine, turn it off, and then set the gearbox selector to park mode
- Open the hood, remove the protective cover, under which there is an inlet pipe that blocks access to the battery
- The battery is mounted on studs, you need to unscrew them, remove the terminals, then remove the battery
- Use a 12 mm wrench to unscrew all the bolts of the seat into which the battery is inserted
- Once the oil filter is accessible, you should replace it with a new element.
- Use a 19 mm wrench and unscrew the drain plug. Wait until the used oil has completely drained into the prepared container.
- When removing the pan, you must act carefully, as a small amount of oil residue, dirt and metal shavings may remain on its surface. The tray must be thoroughly cleaned, rinsed and dried.
- Use a 10 mm wrench and unscrew the four bolts holding the oil exchanger - the so-called fine oil filter. Instead, put a new, exactly the same element. It is also advisable to replace the gasket
- Take a 10 mm wrench and unscrew the variator housing bolts located around the entire perimeter of the cover (crankcase). Remove the crankcase to gain access to the coarse filter and then replace it
- The coarse filter is held in place by three bolts, they are also unscrewed with a 10 mm wrench
- There is a gasket on the crankcase that needs to be washed or replaced
- Clean the crankcase and put it in place, securing it with bolts with a force of 15-18 N/m
- Tighten the drain plug with a 19 mm wrench
- Fill with new transmission oil. The liquid is poured into the hole with a dipstick, which must first be pulled out (so as not to interfere). As soon as the volume of liquid is brought to the desired level, close the plug and start the engine.
- The engine should run for 5-10 minutes, and the gearbox should be operated a little in all modes so that the oil is mixed more efficiently
- Stop the engine and check the fluid level again. If it is normal, the oil change process in the Mitsubishi ASX 1.8 variator has been successfully completed.
