Transmission Filter on the 2017 Subaru Exiga: What You Need to Know

When it comes to the 2017 Subaru Exiga, understanding the transmission system and its components is crucial for keeping the vehicle running smoothly. One common question from owners and enthusiasts alike is whether this particular model uses a transmission filter and if so, what role it plays and how it should be maintained.

After reviewing technical sources and Subaru's official service materials for the 2017 Subaru Exiga, it turns out that this vehicle does not use a traditional transmission filter in the conventional sense. Instead, the Exiga's transmission system, specifically its CVT (Continuously Variable Transmission), relies on the transmission fluid and a built-in, non-serviceable screen filter to protect the transmission components.

So why doesn't the 2017 Subaru Exiga have a replaceable transmission filter? The design philosophy behind the CVT and many modern transmissions is to simplify maintenance and improve reliability. The Exiga's automatic transmission uses a sealed CVT unit that contains a fine mesh screen to filter out contaminants from the transmission fluid. This screen is integrated inside the transmission and is not designed to be removed or replaced separately during routine servicing.

This approach has some advantages. It helps reduce the risk of damage or contamination during servicing since opening the transmission and replacing a filter can be complex and costly. Instead, the main maintenance task becomes regular transmission fluid changes using the correct Subaru-approved fluid type, which helps keep the transmission clean and prolong its life.

That said, the absence of a serviceable transmission filter does mean that owners should be extra attentive to the condition of the transmission fluid. Over time, fluid degrades and collects particles and wear debris, and if not changed, this can lead to increased wear or transmission issues. Subaru recommends following their scheduled maintenance intervals closely to keep things in top shape.

For those who do have a transmission filter as a general concept, here's why the part is important and what it typically involves:

The transmission filter plays a crucial role in maintaining your vehicle's transmission system. It acts like a gatekeeper, filtering out dirt, metal slivers, and other contaminants that sneak into the transmission fluid during everyday driving. This filtering helps protect sensitive components like gears, clutches, and the torque converter from premature wear and failure. For vehicles that do have it, a clogged or dirty transmission filter can lead to symptoms like rough shifting, slipping gears, or even transmission overheating.

Replacing or maintaining a transmission filter as part of regular servicing ensures clean fluid is circulating in the transmission system. Usually, the filter is replaced in conjunction with a transmission fluid change. This replacement helps maintain optimal fluid flow, prevents blockages, and ultimately supports smooth gear shifts and the longevity of the transmission.

Proper transmission filter maintenance typically involves the following steps:

• Draining the old transmission fluid
• Removing the transmission pan to access the filter
• Replacing the old filter with a new one
• Refitting the transmission pan with a new gasket or seal
• Refilling the transmission with fresh, manufacturer-approved fluid
• Checking the fluid level precisely after refilling, as low or overfilled levels can cause issues

While the 2017 Subaru Exiga does not use a separately serviceable transmission filter, owners should still be vigilant about keeping the transmission fluid fresh and clean. Using the correct Subaru CVT fluid and sticking to the recommended service intervals is the best way to protect this vital component. Generally, Subaru suggests fluid changes every 60,000 kilometres under normal driving conditions, but more frequent changes might be necessary if the vehicle is exposed to harsh conditions or heavy towing.

In essence, even though you won't be popping out and swapping a transmission filter on your 2017 Subaru Exiga, understanding the role a filter plays in other transmissions helps highlight the importance of fluid maintenance. Regular servicing with quality fluid and monitoring transmission behaviour can save owners from costly repairs and keep their Subaru running smoothly for years to come.
