Parts for your 2013 Toyota Fortuner-Transmission filter

2013 Toyota Fortuner transmission-filter: what it does and when to service it

Based on Toyota technical references—including the Toyota Repair Manuals for the A340/A343 and A750 series automatics, the Fortuner/Hilux New Car Features manual, and Toyota’s Electronic Parts Catalogue (which lists the internal “Strainer Assy, Oil” as 35330-30050 for A340/A343 and 35330-60050 for A750F)—the 2013 Toyota Fortuner fitted with an automatic transmission does use a transmission-filter (oil strainer) inside the pan. Manual (5-speed) Fortuner models don’t run a transmission-filter, they use gear oil and a magnetic drain plug instead.

On the auto, the transmission-filter’s job is simple but vital: screen out clutch material and wear particles so the valve body and solenoids keep working sweetly. It’s a robust, mesh-style strainer designed for the life of the unit, backed up by magnets in the pan to catch fine metallic fuzz. Toyota’s factory literature treats it as “replace-on-condition”, but in real-world Aussie and Kiwi conditions—think heat, towing a boat or caravan, or lots of stop–start—it’s smart to include the transmission-filter in periodic servicing.

For a 2013 Fortuner, expect one of two autos depending on market: the 4‑speed A343 (commonly using Toyota ATF Type T‑IV) or the 5‑speed A750F (using Toyota ATF WS). The exact fluid spec is critical, check the build plate, dipstick label (if fitted), or confirm by VIN. When the pan’s off, the strainer is right there—swapping it while the ATF is being refreshed is easy preventative maintenance.

A good workshop approach many owners choose:

• Service interval: every 80,000–100,000 km for mixed use, or 60,000 km if towing, off‑roading, or working hard in the heat.
• Use the correct Toyota ATF (WS or T‑IV as applicable), a new pan gasket or sealant as specified, and clean the pan magnets thoroughly.
• Refill and set fluid level at the correct temperature using the factory procedure (especially on “sealed” A750F units with an overflow fill).

Signs the transmission-filter service is due include delayed engagement, shudder on take‑off, or dark, burnt‑smelling fluid. Keeping the filter and fluid fresh helps the Fortuner shift cleanly, protects the valve body, and can head off bigger bills down the track. For manual Fortuners, skip the transmission-filter—stick to regular gearbox oil changes and magnet checks.

Popular questions

Does a 2013 Toyota Fortuner have a transmission-filter?
Automatic models do—an internal oil strainer inside the transmission pan. Manual models don’t use a transmission-filter, they rely on the correct gear oil and a magnetic drain plug.

How often should the transmission-filter be replaced?
Toyota labels it replace-on-condition, but many AU/NZ workshops recommend replacing the strainer when the pan is removed for fluid service—about every 80,000–100,000 km, or 60,000 km for heavy towing or off‑road use.

What transmission fluid does a 2013 Fortuner use?
Most A750F autos take Toyota ATF WS, while A343 4‑speeds commonly specify Toyota ATF Type T‑IV. Always confirm by VIN or the transmission label before servicing.
