1997 Daihatsu Gran Move transmission filter: what’s fitted and how to look after it

Based on the 1997 Daihatsu Pyzar/Gran Move L11 service manual (Automatic Transmission section) and the Daihatsu Electronic Parts Catalogue for the L11 platform (A/T group listing an Oil Strainer and pan gasket), the 4‑speed automatic Gran Move uses an in‑pan transmission oil strainer (often called a filter), while the 5‑speed manual variant does not use a filter at all. The manual gearbox relies on clean gear oil and a magnetic drain plug to capture wear particles, so there’s nothing to replace besides the oil itself.

For owners of the automatic, the transmission filter’s job is to catch clutch material, fine metal, and other debris so the ATF can keep the valve body, pump and solenoids working sweet as. On this Daihatsu, the “filter” is a flat strainer mounted inside the transmission pan. It’s not a spin‑on canister, you access it by dropping the pan. During servicing, the pan comes off, the magnets are cleaned, the strainer is replaced, and a fresh pan gasket goes on before refilling with the correct ATF.

In Aussie and Kiwi conditions—with plenty of stop‑start driving and heat—most technicians recommend inspecting the pan and replacing the strainer around every 60,000 km, or sooner if the fluid is dark, burnt‑smelling, or there are signs of shudder or rough shifts. Always use the ATF grade specified for the Gran Move’s A/T (commonly a Dexron III‑type fluid for this era, confirm against the vehicle handbook or service data). A proper service means measuring what comes out, refilling in stages, and setting the level hot with the selector cycled through the gears on level ground.

Skipping the filter and fluid service can let gritty ATF erode shift quality, glaze clutch packs, and gum up solenoids. On the flipside, a tidy pan, fresh strainer and clean fluid help the little Daihatsu’s auto shift crisply and last longer. If the vehicle is used for towing or lots of urban short trips, shorten the intervals—heat is the enemy of ATF.

• Tell‑tales it’s due: delayed engagement into Drive/Reverse, flare on upshifts, or a whine under light throttle.
• What to replace: strainer, pan gasket, and—if fitted—pan sealing washers, clean the magnets every time.
• Good practice: use a new strainer bolt O‑ring if specified, torque pan bolts evenly to avoid warping.

For the 5‑speed manual Gran Move, there’s no transmission filter by design—just drain and refill the correct GL‑4 gear oil at the advised interval and clean the magnetic plug.

Popular questions

Does my 1997 Gran Move definitely have a transmission filter?
If it’s the 4‑speed automatic, yes—there’s an internal in‑pan oil strainer that’s replaced during a pan‑off service. If it’s the 5‑speed manual, no filter is used, only the gear oil is serviced. Checking the build plate or shift pattern on the knob will confirm which you have.

What ATF should be used after replacing the filter?
For the automatic, use an ATF meeting the specification listed in the vehicle handbook or service manual for the L11 Gran Move—typically a Dexron III‑type for this model year. Avoid universal fluids unless they explicitly meet that spec, and always set the fluid level hot after cycling through the gears.

How often should the Gran Move’s auto transmission filter be changed?
A practical interval for Australia and New Zealand is around every 60,000 km, or sooner with heavy towing, hot climate use, or if the ATF looks or smells off. The service should include a new pan gasket, cleaning the magnets, and the correct refill and level‑set procedure.
