2020 Mitsubishi Eclipse Cross Transmission Filter: What’s Actually Fitted and What That Means for Servicing

The 2020 Mitsubishi Eclipse Cross runs an INVECS-III continuously variable transmission (CVT), sourced from Jatco in this generation. Referencing the factory Eclipse Cross Service Manual (CVT section), the 2020 Owner’s Manual maintenance schedule, and Jatco’s technical overview for its CVT families, this model does not use a conventional, serviceable “transmission filter” like the spin-on or pan-mounted filters seen in many traditional automatics. Instead, it relies on internal filtration designed to last the life of the unit, with any filter components only addressed during transmission disassembly or overhaul.

Here’s why a routine, replaceable transmission filter isn’t part of normal servicing on this vehicle:

• Integrated filtration: The CVT has an internal strainer/screen and fine filtration within the transmission assembly. These components aren’t accessible without significant disassembly and are not listed as periodic service items in Mitsubishi’s maintenance schedule.
• No removable pan: Unlike many torque-converter automatics, the Eclipse Cross CVT doesn’t have a simple drop-pan/replace-filter arrangement.
• Service literature focus on fluid: Mitsubishi’s schedule for the 2020 model year in AU/NZ focuses on CVT fluid inspection and replacement under specified conditions, there’s no call-out for a transmission filter change.

Some Jatco-based CVTs used by various brands include a small external cooler-return filter. Parts catalogues and the Eclipse Cross Service Manual for this model year indicate that if present in certain markets or configurations, it’s not designated a routine maintenance item and is typically only replaced if contamination is suspected or during major repair work. For local AU/NZ servicing, workshops generally inspect fluid condition, check for codes or symptoms (flare, shudder, overheat events), and replace CVT fluid at intervals consistent with the Owner’s Manual or severe-use recommendations.

Owners who tow, sit in heavy traffic, or drive in hot conditions should be especially attentive to fluid condition and cooling system health. If there’s evidence of debris in the fluid, repeated overheat warnings, or drivability issues, a transmission specialist can assess whether deeper service—up to and including internal filter/strainer replacement during overhaul—is warranted. For day-to-day servicing, though, a “transmission filter” purchase or replacement isn’t a normal requirement for the 2020 Eclipse Cross.

Popular questions

Does the 2020 Eclipse Cross have a replaceable transmission filter?
It uses internal filtration inside the CVT rather than a serviceable, external filter. Mitsubishi’s maintenance schedule doesn’t list a filter change as a periodic service. Any filter components are typically addressed only during major repair or overhaul.

When should the CVT fluid be changed on a 2020 Eclipse Cross?
Follow the intervals in the Owner’s Manual. Many AU/NZ workshops recommend more frequent fluid changes under severe conditions (towing, hot climates, stop–start city driving). Fresh, correct-spec CVT fluid is the key day-to-day service item for longevity.

Can an external CVT cooler filter be added or upgraded?
Aftermarket options exist, but suitability depends on the specific cooler layout and may affect warranty or introduce restriction risks if not sized correctly. A transmission specialist familiar with Mitsubishi/Jatco CVTs can advise on safe, model-appropriate upgrades.
