The Mitsubishi Xpander has just received a significant change in the kitchen sector. More precisely on the transmission component or automatic gearbox.
Devices that are useful for distributing power from the engine to the wheels are now using the Continuous Variable Transmission (CVT) type. Not only superior in driving comfort, Mitsubishi claims that the CVT in the Xpander does not need to be changed to do an oil change.

Before going any further, it's a good idea to get to know the CVT transmission model in question. The type of CVT automatic transmission has a different way of working compared to the previous Xpander, namely the conventional automatic (AT). CVT processes power to be transferred to the engine to the wheels via a steel belt that connects the unique pulleys.
Both of these pulleys (driven pulley and drive pulley) can be enlarged and reduced thereby changing the ratio between the pulleys continuously. This change in ratio finally allows power from the engine to be distributed gradually as speed increases. Because the change in ratio does not go through changing gears, there is no jerk when the ratio changes as in conventional automatic transmissions. As a result, changes in acceleration also occur very smooth and comfortable.
Mitsubishi explained in a press release, adjustments to the pulleys are made possible by the fluid pump system. Of course here the fluid in question is oil or a special CVT lubricant. Yes, in a CVT transmission, oil does not serve as a lubricant or coolant just like in an engine, but is part of the working system of these components.
Because it has an important task, Mitsubishi mixes its CVT with oil with a very long service life, it doesn't even need to be replaced. "Mitsubishi cars have seamless transmissions and long-life maintenance. So there is no special maintenance and no oil changes," said Boediarto as General Manager After Sales of PT Mitsubishi Motors Krama Yudha Sales Indonesia (MMKSI).
According to Mitsubishi in a statement, this is possible because the CVT transmission in their vehicle is made with a long service life. Even the CVT device can last up to 3 years or 100 thousand km of use without any problems.
Although it is claimed to have a long life, and there is no special maintenance, users of this CVT transmission car still have to carry out routine checks at every kilometer that has been determined as a routine service to monitor the condition of the CVT transmission.
"Regular checks are carried out every 20 thousand km at the official Mitsubishi workshop to see the condition, both in terms of quantity and quality of the CVT transmission," added Boediarto via text message some time ago.
CVT oil as an important part of this sophisticated transmission is also one that is checked for quantity and quality. During routine service, the amount will be measured carefully. Not only that, the mechanical team at the official workshop will also check if there is seepage coming out of this gearbox.
"Checking for CVT oil leaks and checking the quantity of CVT oil with special methods depending on the type of vehicle. Mitsubishi mechanics have been trained to carry out these inspections," added Boediarto.
Well, according to Mitsubishi, transmissions whose oil does not need to be changed are those whose cars are used under normal conditions. However, if the car is used very often or is classified as heavy, for example as an operational vehicle, it is recommended that Xpander be obliged to change the CVT oil every multiple of 40 thousand km.
The presence of the CVT transmission in the Mitsubishi Xpander proves that now technological progress has been successfully accepted by the community. In fact, the twin duo of Toyota Avanza and Daihatsu Xenia are now entrusting the task of automatic transmission to the CVT as well
