Parts for your 2013 Suzuki Splash-Transmission filter

2013 Suzuki Splash transmission-filter — is there one?

For the 2013 Suzuki Splash, a separate, serviceable transmission filter isn’t used. On manual models there’s no filter at all, just gearbox oil. On automatic models (the Aisin 4‑speed auto commonly fitted to K12B/K10B Splash variants, known in industry literature as Aisin AW60‑41SN/AF13), the “filter” is an internal metal-mesh strainer that isn’t designed to be replaced during routine servicing.

This position is backed by technical documentation: Suzuki workshop and maintenance schedules for Splash/Swift platforms of this era don’t list any transmission-filter replacement, they only specify checking or replacing automatic transmission fluid (ATF). Aisin service information for the AW60‑41SN/AF13 family likewise describes an internal strainer located within the transmission casing/valve body area, requiring a partial teardown to access. Trade databases used in Australia and New Zealand (such as Autodata/HaynesPro and OEM EPC listings) don’t list a service filter for the Splash automatic, reinforcing that it isn’t a routine service part.

Why the filter isn’t a service item on this model:

• The Aisin 4‑speed uses an internal, fine metal-mesh strainer primarily to protect the pump and valve body, it’s intended to last the life of the unit under normal conditions.
• There’s no removable pan with a replaceable cartridge, accessing the strainer requires transmission disassembly well beyond normal service procedures.
• Manufacturer maintenance schedules focus on fluid condition and level checks, not filter swaps, for reliability and cost control.

What owners should do instead: keep the ATF in good nick. Use the correct spec fluid (commonly JWS 3309/Toyota T‑IV/Suzuki ATF 3317), and follow the temperature-based level setting procedure outlined in service literature. Many workshops in AU/NZ suggest a drain-and-refill or a measured exchange every 60,000–90,000 km if the car sees urban stop–start, heat, or towing. If shifting quality is off, a fluid service and adaptation checks are the first steps before anyone talks about opening the transmission.

Note for buyers: if you see aftermarket “transmission filters” listed for a 2013 Splash, they’re typically generic or for different gearboxes. For the Splash, the correct maintenance path is fluid, seals, and software checks—not a filter change—unless the unit is being overhauled by a transmission specialist.

Popular questions

Does a 2013 Suzuki Splash have a replaceable transmission filter?
It doesn’t. Manuals have no filter, and the 4‑speed auto uses an internal strainer. Suzuki maintenance schedules and Aisin technical data don’t specify filter replacement as a service item.

How should the auto transmission be serviced if there’s no filter?
Stick to the right ATF spec (JWS 3309/T‑IV) and follow the temperature-based level-setting method. Many local workshops recommend fluid changes around 60,000–90,000 km in tougher conditions. That’s the best way to protect the unit.

Can the internal strainer be replaced during a rebuild?
Yes, but only during transmission disassembly. It’s a job for an auto-trans specialist and isn’t part of regular servicing.
