Parts for your 2015 Suzuki Splash-Transmission filter

2015 Suzuki Splash transmissionfilter: what it is, whether it’s fitted, and how to look after it

Based on technical documentation for the platform and gearbox family, the 2015 Suzuki Splash fitted with the 4‑speed automatic uses an internal transmissionfilter (ATF strainer) inside the pan. Manual Splash models don’t use a transmissionfilter at all. References include: Suzuki Splash/RS415 service information for the 4‑speed A/T (Aisin AW60‑41SN/AF13‑II) listing an oil strainer and pan magnets, Aisin AW60‑41SN overhaul/parts manuals showing the internal strainer, and Opel/Vauxhall Agila B (sister model) AF13‑II workshop material that likewise specifies an internal oil strainer. Manual gearboxes in these sources show no filter, relying on a magnetic drain plug and periodic oil changes.

For Splash owners with the 4‑speed auto, the transmissionfilter’s job is to trap clutch material and tiny metal particles before they can circulate through the hydraulic circuits, solenoids, and valve body. Keeping that debris out helps the transmission hold correct line pressure, shift smoothly, and live a long, drama‑free life. It’s not an external, spin‑on item, it’s a flat internal strainer that sits above the pan, so it’s replaced during a pan‑off service rather than at every fluid change.

Suzuki doesn’t specify a strict replacement interval for the Splash’s transmissionfilter, but a sensible approach in Australian and New Zealand conditions is to replace it whenever the pan comes off—typically around 100,000–150,000 km, sooner if the vehicle tows, spends its days in stop‑start traffic, or shows shifting issues. During service, a good workshop will remove the pan, clean the magnets, inspect the sediment, fit a new strainer and pan gasket, and refill with the correct ATF (Suzuki ATF 3317/JWS 3309 spec). Level setting on this Aisin unit is a temperature‑dependent procedure via the level plug, so having the right scan tool and following the OEM method matters.

Signs that the transmissionfilter is due include delayed engagement when selecting Drive or Reverse, flare or slip on upshifts, harsh or hesitant shifts, and dark, burnt‑smelling fluid. None of those automatically mean the gearbox is cooked, often a proper pan‑off service with a new filter and fresh fluid will restore its manners. If your Splash is the manual version, relax—there’s no transmissionfilter to replace. Just change the manual trans oil at sensible intervals, and let the drain‑plug magnet do its thing.

Need‑to‑know tips

• Auto Splash: yes, it has an internal transmissionfilter/strainer.
• Manual Splash: no transmissionfilter is used.
• Use ATF meeting JWS 3309 (Suzuki ATF 3317). Avoid universal fluids that don’t list this spec.
• Have the fluid level set at the specified temperature with the correct procedure—there’s no dipstick.

Popular questions about 2015 Suzuki Splash transmissionfilter

Does a 2015 Suzuki Splash have a transmissionfilter?

Yes—if it’s the 4‑speed automatic. That auto uses an internal strainer above the pan. The manual Splash doesn’t use a transmissionfilter at all, relying on clean gear oil and a magnetic drain plug.

How often should the Splash’s transmissionfilter be replaced?

There’s no hard‑and‑fast factory interval. Most workshops in Australia and New Zealand recommend replacing the strainer whenever the pan is off, commonly around 100,000–150,000 km, or earlier with heavy use or shifting symptoms.

What ATF should be used after replacing the transmissionfilter?

Use ATF that meets JWS 3309 (Suzuki ATF 3317). The level must be set via the fill/level plugs at the specified temperature, so it’s best done by a workshop familiar with Aisin 4‑speed procedures.
