Parts for your 2023 Suzuki Splash-Transmission filter

2023 Suzuki Splash transmission filter: is there one, and what should owners do?

Short answer: a separate, serviceable transmission filter isn’t used on the 2023 Suzuki Splash. The Splash platform (sold globally as Splash/Ritz RB series and discontinued well before 2023) was offered with either a 5‑speed manual or an Aisin‑supplied 4‑speed automatic. In Suzuki’s factory service information and Electronic Parts Catalogue for the RB series, the automatic uses an internal metal-mesh oil strainer inside the transmission pan/valve body, not an external spin‑on or cartridge filter. There’s no scheduled “filter” change listed, only fluid service. This layout is typical of small Aisin 4‑speed autos used by Suzuki and others.

Technical basis for the call: Suzuki Splash/Ritz RB service manual AT section and the Suzuki EPC list an “oil strainer” within the automatic transmission assembly and do not show any external transmission filter for the vehicle. Aisin’s 4‑speed units of this era are designed around a suction screen/strainer that protects the pump and valve body, it’s cleaned or replaced only when the pan is removed for internal service, not as a routine stand‑alone part swap.

Why they didn’t fit a conventional filter: compact 4‑speed autos like the Splash’s prioritise packaging and simplicity. A robust, reusable strainer plus periodic ATF replacement keeps debris in check without the cost, space and plumbing of an external filter. Because the strainer is internal and metal-mesh, it doesn’t clog rapidly under normal conditions, when the pan is off, it can be inspected and renewed as needed.

What owners in Australia and New Zealand should do instead:

• Follow the owner’s manual for automatic transmission fluid (ATF) grade and intervals. On this platform, the spec commonly aligns with JWS 3309/Toyota T‑IV–type fluid, but always confirm by VIN or handbook.
• In local stop‑start, hot, or towing conditions, a conservative drain‑and‑fill every 40,000–60,000 km (or 3–4 years) helps shifting quality and longevity.
• If the pan is dropped (for a leak, solenoid work or harsh shifts), ask the workshop to clean the pan and magnet, inspect/replace the internal strainer, and fit a new pan gasket. Correct torque on pan bolts matters.
• Manual Splash models don’t have a transmission filter at all. They use gear oil, change it per the schedule, or earlier for harsh service.

Bottom line for a 2023‑registered Splash (often a later compliance/import of the RB series): there’s no separate transmission filter to buy or book in for. Spend the money on the right ATF, sensible service intervals, and careful pan/strainer attention if and when the box is opened.

Does a 2023 Suzuki Splash have a transmission filter?

No. It doesn’t use a separate, serviceable filter. The 4‑speed auto has an internal metal-mesh strainer, and manuals have none. Suzuki’s RB‑series service manual and EPC show only the internal strainer, with no external filter listed.

How often should the Splash’s ATF be changed?

For Australian and New Zealand conditions, a drain‑and‑fill every 40,000–60,000 km (or 3–4 years) is a safe play, especially with city driving or heat. Always use the exact ATF grade specified in the owner’s manual.

Can the internal strainer be replaced or cleaned?

Yes—when the transmission pan is off. It’s not a routine item, but during pan service, solenoid work or an overhaul, a new strainer and fresh gasket are good practice, along with cleaning the pan and magnet.
