Parts for your 2016 Suzuki Splash-Transmission filter

2016 Suzuki Splash transmission filter — what’s actually fitted?

After checking recognised technical references — Suzuki workshop service information for Splash/Agila B with the K12B engine and 4‑speed auto, the ATSG/Aisin AW60‑40LE technical manual, plus Autodata/Haynes service guidance for Suzuki Splash/Opel Agila B — the verdict is straightforward: there’s no external, service‑replaceable transmission filter on a 2016 Suzuki Splash. The 5‑speed manual has no filter at all, and the 4‑speed automatic uses an internal oil strainer and pan magnet inside the transaxle rather than a screw‑on or in‑line filter (the strainer sits above the valve body and isn’t listed as a routine service item in those sources).

That design is normal for small Aisin 4‑speed autos of this era. Instead of a paper cartridge, Suzuki specifies a fine metal mesh strainer and strong pan magnet to capture clutch dust and wear particles. Because the strainer is internal, replacing it requires lowering the valve body or deeper disassembly, which is why the factory maintenance schedule focuses on fluid level/condition checks and doesn’t call out “filter replacement” as periodic service. The approach reduces owner maintenance complexity while still protecting the hydraulics and solenoids.

What owners can do instead to keep the Splash shifting sweetly:

• Have the ATF inspected for level, colour and smell at regular services, top up or change if discoloured, burnt, or contaminated.
• Use the correct spec fluid for the 4‑speed auto (JWS 3309/T‑IV type, as specified by Suzuki for the Aisin unit).
• If there are shift shudders or harsh changes, a pan‑off service to clean the magnet and mesh strainer can help — it’s a workshop job.
• While many factory schedules say “inspect only” for life, many transmission specialists in AU/NZ suggest refreshing ATF around 60,000–80,000 km (or sooner with lots of city or towing work).

For manual Splash models, there’s simply no filter by design. Routine gearbox oil changes with the correct GL‑4 lubricant and checking for leaks are the go‑tos for longevity.

Technical references consulted: Suzuki workshop service information for Splash/Agila B (K12B, 4AT), Aisin/ATSG AW60‑40LE documentation describing the internal oil strainer arrangement, and Autodata/Haynes service schedules noting inspection of ATF without a serviceable external filter.

Popular questions about the 2016 Suzuki Splash “transmission filter”

Does the 2016 Splash have a replaceable transmission filter?
Not in the usual sense. The 4‑speed auto uses an internal mesh strainer and magnet, and the manual has no filter. There’s no external, service‑replaceable filter listed in Suzuki parts catalogues for this model. Workshops can access and clean the internal strainer during a pan‑off service if needed.

When should the transmission fluid be changed on a Splash?
Many factory schedules list fluid checks rather than a fixed change interval. In real‑world AU/NZ driving, a preventative ATF change around 60,000–80,000 km is a fair call, especially with lots of stop‑start or hilly driving. Always use the correct JWS 3309/T‑IV‑type fluid specified by Suzuki.

Can the internal strainer be replaced?
Yes, but it’s not considered routine maintenance. Reaching the strainer involves removing the pan and valve body, it’s typically done during repair or overhaul, or when there’s evidence of contamination. Most owners will see good results from fluid service and pan/magnet cleaning first.
