Understanding the Transmission Filter on the 2020 Mitsubishi ASX

The 2020 Mitsubishi ASX is a popular compact SUV known for its reliability and smooth performance. One important component in many vehicles with automatic transmissions is the transmission filter, which plays a crucial role in maintaining the health and efficiency of the transmission system. But is a transmission filter actually fitted to the 2020 Mitsubishi ASX? And if so, what should owners know about its purpose, maintenance, and replacement?

After referencing multiple technical sources including Mitsubishi service manuals and automotive parts databases for the 2020 Mitsubishi ASX, it's clear that this model does indeed have a transmission filter fitted, but only with certain transmission types. The ASX typically comes with a CVT (Continuously Variable Transmission) or a conventional automatic transmission option in some markets. In vehicles equipped with the conventional automatic transmission, a transmission filter is present. However, in CVT versions, the design often includes a mesh or screen-type filter within the transmission fluid system rather than a traditional replaceable filter element.

Let's take a closer look at the transmission filter itself and what it does for the ASX's automatic transmission.

The transmission filter is a component located inside the transmission pan. Its job is quite straightforward but incredibly important. As automatic transmission fluid (ATF) circulates through the transmission, it picks up dirt, debris, and metallic particles caused by everyday wear and tear. The transmission filter traps these contaminants to prevent them from circulating through delicate components such as clutch packs and valve bodies. Without a filter, this debris could cause serious damage, leading to costly repairs or transmission failure.

For the 2020 Mitsubishi ASX that uses a conventional automatic transmission, the filter is a paper or mesh element housed inside the transmission pan, often alongside a magnet. The magnet helps attract ferrous metal particles, while the filter captures other contaminants. Over time, just like an engine air filter, this transmission filter gets clogged up and becomes less effective at protecting the transmission.

That's why regular maintenance is essential. Mitsubishi recommends inspecting the transmission filter and fluid at designated service intervals, which for the ASX is generally around every 60,000 to 90,000 kilometres or every five years, whichever comes first. However, this can vary depending on driving conditions. For example, if the ASX spends a lot of time driving in heavy traffic, over rough or dusty roads, or towing loads, the transmission fluid and filter may need to be checked and changed more frequently.

When it's time to service the transmission filter on the 2020 ASX, the process typically involves draining the old transmission fluid, removing the transmission pan, and carefully replacing the filter element. It's also advisable to replace the transmission pan gasket while you're at it to prevent leaks. After installing the new filter and gasket, fresh transmission fluid is added to the transmission to ensure proper operation and longevity.

Some signs that the ASX's transmission filter might need attention include sluggish or delayed gear changes, unusual noises like whining or grinding, or even transmission overheating. If these symptoms appear, it's a good idea to get the transmission checked by a qualified technician as soon as possible to avoid further damage.

For owners of the 2020 Mitsubishi ASX equipped with the CVT, the approach to transmission filtering is a little different. CVTs use a high-precision belt or chain-driven system and typically rely on fluid with specific properties for smooth operation. Instead of a traditional replaceable transmission filter, the CVT system commonly employs fine screens or mesh filters inside the transmission housing. These are designed to last the life of the transmission and are not generally serviceable or replaced during routine maintenance.

Instead of replacing a filter, CVT maintenance for the ASX mostly focuses on ensuring the transmission fluid is changed according to Mitsubishi's schedule using the correct CVT fluid. Clean, fresh fluid is crucial for preventing wear and ensuring consistent transmission performance. Neglecting regular CVT fluid changes can result in poor transmission behaviour and reduced lifespan of the CVT components.

In summary, whether your 2020 Mitsubishi ASX has a conventional automatic transmission or a CVT will determine the type of transmission filter setup it has and the maintenance needed. Conventional automatics use a replaceable filter that traps contaminants and needs periodic changing to keep the transmission running smoothly. On the other hand, CVT models rely on internal mesh filters and fluid quality, with fluid replacement playing the central role in maintenance.

Keeping up with transmission filter checks and fluid changes is a smart way to protect your ASX's transmission investment and enjoy reliable, smooth shifting on every drive. It's one of those maintenance tasks that might fly under the radar but really helps prevent costly repairs down the track. So whether you are cruising around the city or heading off-road, a little attention to your ASX's transmission filter and fluid goes a long way.
