Parts for your 2010 Toyota Ractis-Transmission filter

2010 Toyota Ractis transmission filter — what it does and when to service it

Short answer: yes, the 2010 Toyota Ractis does use a transmission filter. Whether it’s fitted with the 4‑speed automatic (Aisin U340E/U341E) or a Toyota CVT (K110/K111 depending on build), there’s an internal oil strainer inside the transmission, and some CVT variants also run an external cooler-line filter. This is supported by Toyota’s Electronic Parts Catalogue and Repair Manual for the Ractis NCP100/NCP120 series, as well as Aisin service data for the U340E and Toyota service specifications for K‑series CVTs.

The transmission filter’s job is to catch clutch material, fine metal and general wear debris so the fluid can keep doing its work—cooling, lubricating and providing hydraulic pressure—without dragging contaminants through the valve body and solenoids. In the Ractis, that “filter” is typically a mesh or felt strainer in the pan. On some CVTs, there’s also a small external cartridge that tidies up what the internal strainer misses.

When should it be looked at? Toyota often lists the factory ATF/CVT fluid as a “filled for life” item under light duty, but in Aussie and Kiwi conditions—stop‑start traffic, heat, hilly commutes—it’s smart to plan inspections around 60,000–100,000 km. The internal strainer is normally serviced when the pan is off for fluid service or repair. The external CVT cooler filter (if fitted) is quick to replace during a drain‑and‑fill. If the pan shows glitter, sludge or a furry magnet, replace the strainer rather than re‑use it.

Fluid choice matters. Use the exact Toyota‑specified fluid: typically Toyota ATF WS for the U340E/U341E, and Toyota CVT Fluid TC or FE for the K‑series CVT (check the label and service info for the correct spec by VIN). Avoid power flushing. Go with a measured drain‑and‑fill, clean the pan and magnet, fit a new gasket/O‑ring, and set the level at the specified fluid temperature using the proper procedure or scan data.

• Watch for symptoms of a restricted filter: delayed engagement, flare shifts, shudder, or fine metal on the drain plug.
• If towing, riding hills, or doing short trips, shorten service intervals.
• After any transmission work, road test and recheck fluid level at temperature.

Handled this way, the Ractis’s transmission stays crisp, cool and reliable for the long haul.

Popular questions

Does the 2010 Toyota Ractis have a transmission filter or strainer?
Yes. Both the 4‑speed auto and the CVT use an internal oil strainer, and certain CVT variants add a small external cooler‑line filter. It’s there to protect valves and bearings from wear particles.

How often should the Ractis transmission filter be changed?
There isn’t a strict time‑based schedule. Plan an inspection around 60,000–100,000 km in local conditions. Replace the internal strainer when the pan is off or if contamination is found, swap the external CVT filter (if fitted) during fluid service.

Which fluid should be used after replacing the filter?
Use Toyota ATF WS for the U340E/U341E, and Toyota CVT Fluid TC or FE for K‑series CVTs, as specified for the exact transmission. Set the level at the correct temperature and avoid power flushes.
