Prevent CVT Gearbox Jerking and Protect Sensitive Valve Bodies
Have you noticed your automatic transmission shifting roughly, lagging during sudden acceleration, whining under heavy loads, or slipping between gear ratios? Over time, the internal mesh layer inside your factory Continuously Variable Transmission (CVT) strainer traps metal wear shavings, friction debris, and dark carbon sludge. This restriction starves the system of vital hydraulic oil. This 100 percent Genuine Toyota replacement CVT transmission filter strainer and metal oil pan gasket kit restores clean fluid routing to protect your car advanced internal electronics.

Leaving a clogged, dirty, or leaking CVT auto filter unreplaced presents a high risk of catastrophic gearbox failure. When oil flow is restricted, internal hydraulic pressure drops instantly, causing the CVT steel belt to slip violently along the driving pulleys. This slippage quickly scores, grooves, and ruins your expensive transmission internals, leading to total gearbox deadlock. Furthermore, an old brittle oil pan gasket will weep fluid continuously, running your transmission oil dangerously low and causing rapid overheating.

Key Features and Benefits
High Flow Micro Strainer Mesh: Fabricated from premium factory-grade fiber element matrix designed to trap microscopic metal shavings and clutch sediments down to single-digit micron levels.

Steady Hydraulic System Pressure: Restores unrestricted, clean CVT fluid tracking to ensure rapid pulley ratio adjustments, smooth acceleration, and sharp throttle response.

Direct Drop In Factory Fitment: Molded precisely to original Toyota transmission oil pan specs to snap cleanly into your internal gear valve body tracking lines with zero modifications.

Airtight Premium Metal Gasket: Includes a high-density, multi-layer original equipment metal pan gasket designed to withstand aggressive gear lubricants and permanently lock out external transmission leaks.

Precise Vehicle Compatibility
This internal CVT gearbox transmission filter and gasket set fits the following models and production years equipped with the K311 CVT Gearbox:

Technical Compatibility Note
Fits strictly the specific vehicle generations and models equipped with Toyota K311 Super CVT-i transmissions listed above utilizing the ATFKIT-ZGE20-G filter footprint. This kit does not fit older 4-speed conventional automatic models (such as first-generation Wish ZNE10 or pre-facelift Altis ZZE122/ZZE142), as those alternative drivetrain architectures utilize modified transmission oil pan footprints, alternative internal tracking clearances, and separate filter bolt configurations.

What are the primary symptoms that my CVT auto filter strainer is completely blocked?
The most common signs include a distinct whining or buzzing mechanical sound from your transmission tunnel when accelerating, delayed engagement when moving your shifter from Park into Drive or Reverse, severe engine hesitations or engine jerking when cruising on the highway, or a transmission error warning light popping up on your dashboard.

Does this purchase package include both the auto filter and the outer pan gasket?
Yes, absolutely. This is a comprehensive, factory-paired maintenance package. It arrives complete with the primary black composite internal CVT filter strainer housing block unit (35330-0W080) and the matching multi-hole premium multi-layer metal oil pan perimeter sealing gasket (35168-12091) inside the box. You do not need to source separate seal items; simply drop them into your transmission box together for a complete leak-free overhaul.

How often should I change the CVT internal filter strainer on my Toyota Wish or Altis?
While basic transmission fluid drains can be completed every 40,000 kilometers, Toyota service specialists highly recommend dropping the lower transmission pan to replace this internal filter strainer element and fresh perimeter gasket every 80,000 to 100,000 kilometers driven. Regular periodic replacement is the single most effective preventative tool to clear out accumulated wear shards, protect your delicate linear solenoid valves, and extend the overall operational life of your car's transmission system.

Is it easy to change this internal automatic transmission oil filter at home?
Replacing an internal CVT filter requires an intermediate to advanced level of DIY mechanical skill, extreme cleaning care, and proper safety gear. To install it safely, ensure your car engine is cooled completely, raise the vehicle securely on frame jack stands, unbolt the oil pan drain plug to empty your old transmission fluid, carefully remove the multi-bolt lower metal pan cover frame assembly (have a drain pan ready to catch any oil drops), thoroughly clean the pan interior surface and clean the built-in collector magnets from metal grit sludges, unbolt the old clogged filter from the valve body, slide this brand-new genuine Toyota strainer flush into the guide track, line up your fresh original metal gasket along the pan tracking rim without pinching, bolt the pan assembly back down to strict factory torque specs, and fill the system exclusively with fresh genuine Toyota CVT fluid lines.
