Parts for your 2000 Daihatsu Gran move-Transmission filter

2000 Daihatsu Gran Move transmission filter: is there one and what should be serviced?

Technical sources point to the 2000 Daihatsu Gran Move (G300 series, also known as Pyzar in some markets) not using a separate, serviceable transmission filter. The factory workshop manual for the G300 automatic transmission identifies an internal oil strainer mounted inside the transmission sump (pan), along with sump magnets, and does not specify an external spin‑on or cartridge filter. Aisin‑Warner literature for the small 4‑speed transverse automatics used by Daihatsu in this era describes a reusable metal‑mesh strainer design, and major parts catalogues list pan gaskets and strainers rather than a stand‑alone transmission filter. Put simply: there’s no conventional “transmission filter” to swap like on some other makes.

Why didn’t Daihatsu fit a replaceable filter on the Gran Move? The transmission architecture relies on a low‑restriction metal gauze strainer to protect the valve body and pump while maintaining stable line pressure, and it teams that with magnets in the pan to capture ferrous wear particles. This keeps the unit compact and cost‑effective, and it’s well‑suited to the moderate torque of the 1.5–1.6‑litre driveline. The intended maintenance approach is fresh fluid at sensible intervals, rather than frequent filter changes.

Owners who are keeping a Gran Move happy should focus on fluid condition and sump housekeeping, especially in Aussie and Kiwi conditions with heat, hills, and the odd bit of towing.

• Change the ATF every 40,000–60,000 km or 2–4 years, sooner if towing, city slogging, or driving in hot climates. Use the fluid grade specified on the dipstick/owner’s manual (typically DEXRON III for this era).
• Prefer a drain‑and‑fill (or two successive drain‑and‑fills a few hundred kilometres apart) to gently refresh most of the fluid. Full power flushes aren’t necessary and can stir up debris in older units.
• If the pan is off (leak repair or shift-quality work), clean the magnets and the strainer with solvent, and replace the pan gasket. Replace the strainer only if damaged or heavily clogged. Follow torque specs on the pan bolts and avoid excess sealant.
• Watch for early signs of ATF trouble: dark or burnt‑smelling fluid, delayed engagement, shudder, or slipping. Don’t ignore leaks—low ATF level is a transmission killer.

These practices align with the Daihatsu G300 workshop guidance (oil strainer and sump service) and the Aisin approach to mesh‑strainer automatics of the late 1990s–early 2000s, where clean fluid and pan maintenance are the core of transmission longevity.

Popular questions

Does the 2000 Daihatsu Gran Move have a replaceable transmission filter?
No. It uses an internal metal‑mesh oil strainer inside the sump and magnets to catch debris. There’s no external spin‑on or cartridge filter to change, servicing focuses on fresh ATF and cleaning the pan, magnets, and strainer when it’s opened.

How often should the ATF be changed on a Gran Move?
As a rule of thumb in Australia and New Zealand, every 40,000–60,000 km or 2–4 years is sensible, sooner if the car tows, idles in traffic a lot, or sees hot conditions. Many owners do one or two drain‑and‑fills rather than a high‑pressure flush on older transmissions.

Can the transmission strainer be cleaned or replaced?
Yes. When the sump is off, the strainer can be removed and cleaned with suitable solvent and compressed air. Replace it only if damaged or severely blocked. Always clean the magnets and fit a new pan gasket on reassembly.
