CVT Transmission Internal Filter - Subaru Parts Pro (31728AA141)
The CVT Transmission Internal Filter - Subaru Parts Pro (31728AA141) is a genuine OEM transmission filtration component designed to help remove contaminants from the continuously variable transmission fluid before it circulates through critical internal passages and components. Manufactured to Subaru Parts Pro’s exact factory specifications, this internal filter provides precise fitment, dependable filtration performance, and seamless integration with the compatible CVT housing, valve body, pump, and fluid circuits.
Constructed from high-quality automotive-grade filter media, molded housing materials, seals, and fluid-resistant components, this CVT transmission filter is engineered to withstand continuous transmission fluid exposure, elevated temperatures, hydraulic pressure, vibration, and demanding everyday driving conditions. Its durable construction helps resist media breakdown, deformation, leakage, flow restriction, and premature deterioration.
Functionally, the internal filter helps capture fine particles, clutch material, metal debris, and other contaminants that can circulate through the transmission fluid. Proper filtration supports cleaner hydraulic fluid, consistent pressure control, smoother CVT operation, and longer service life for sensitive internal transmission components.
The filter is designed to match the transmission’s original mounting location, housing dimensions, fluid passages, sealing surfaces, pickup geometry, and surrounding internal clearances. Replacing a clogged, contaminated, damaged, or deteriorated filter helps restore proper fluid flow and factory transmission filtration performance.
As a genuine Subaru Parts Pro OEM component, this CVT transmission internal filter is manufactured to precise factory dimensions, filtration specifications, flow requirements, sealing standards, material requirements, and fitment tolerances. OEM engineering helps ensure dependable compatibility without the trimming, modification, sealing compromises, or flow mismatches that can occur with incorrectly matched aftermarket filters.
Installation is recommended during applicable CVT service or when internal transmission work indicates the filter should be replaced. Professional transmission service is recommended because installation may require fluid draining, transmission disassembly, correct sealing procedures, and proper CVT fluid refill and level verification.

Subaru
Genuine Subaru parts are built to the specifications Subaru engineers used on the production line, which matters more on these platforms than most. Symmetrical all-wheel drive requires matched components across both axles, and the boxer engine's horizontally opposed layout uses parts with no aftermarket equivalent in fit or material spec. Ordering OEM protects drivetrain longevity, factory warranty coverage, and resale value.
