Parts for your 2010 Suzuki Splash-Transmission filter

2010 Suzuki Splash transmission filter — is it there, and what to do about it?

For the 2010 Suzuki Splash, whether a transmission filter is relevant depends on the gearbox fitted. Technical references including the Suzuki Splash/Agila B workshop manual (Automatic Transmission section), Suzuki Electronic Parts Catalogue listings for the RB-series Splash, and Aisin 4‑speed automatic service literature confirm that manual gearboxes on the Splash don’t use a transmission oil filter, while the 4‑speed torque‑converter automatic (Aisin unit as used in Splash/Agila B 1.2 petrol) uses an internal ATF strainer (screen) inside the pan. It isn’t an external spin‑on filter. Routine servicing typically specifies ATF changes and pan/magnet cleaning, the internal strainer is generally replaced during overhaul or if contamination is found.

For Splash models fitted with the 4‑speed automatic, the transmission filter (technically a fine mesh strainer) plays a big role in looking after the auto. It sits inside the transmission sump, catching clutch material and tiny metal particles so the hydraulic circuits and solenoids can do their job smoothly. Keeping that flow clean helps the transmission shift crisply, reduce shudder, and extend the life of seals and clutches.

Because the Splash’s filter is internal, it’s not a quick driveway swap like an engine oil filter. Most routine services focus on replacing the automatic transmission fluid (use the specified ATF—many Aisin 4‑speeds call for JWS 3309/T‑IV type fluid, check the owner’s handbook or service data), inspecting for leaks, and cleaning the pan and magnet if the sump is dropped. The internal strainer is usually replaced when there’s evidence of debris, after overheating, or during a rebuild. Plenty of local workshops will drop the pan, clean the magnet, fit a new gasket, and refill with fresh ATF to the correct temperature‑based level—good practice if the car has done higher kilometres or has seen city stop‑start duty.

As a rule of thumb in Australia and New Zealand, owners often plan ATF service between 60,000 and 90,000 km, sooner for heavy use (short trips, towing, steep terrain). If shifts feel lazy, there’s delay engaging Drive/Reverse, or the fluid looks dark and smells burnt, it’s time to act.

• Watch for symptoms: flare between gears, harsh shifts, or shudder under light throttle.
• Service approach: fresh ATF, clean the pan and magnet, consider replacing the internal strainer if contamination is present.
• Avoid mixing fluids—stick to the specified ATF and correct fill procedure (level checked at the right temperature).
• Manual Splash models: no transmission filter is fitted, just change the gear oil per the schedule and check for leaks.

Does the 2010 Suzuki Splash have a transmission filter?

Manual versions don’t have a transmission filter. Automatic versions do, but it’s an internal ATF strainer inside the sump rather than an external filter. It’s typically serviced by dropping the pan during more in‑depth maintenance or overhaul.

How often should the automatic’s filter or strainer be serviced?

Most routine maintenance focuses on ATF changes every 60,000–90,000 km in local conditions. The internal strainer is usually inspected and only replaced if there’s debris or during a rebuild. If the fluid is burnt or there are shift issues, pan removal, magnet cleaning, and strainer replacement are sensible.

What ATF should be used in a 2010 Splash automatic?

Use the fluid specified by Suzuki for the Aisin 4‑speed—commonly a JWS 3309/T‑IV–type ATF. Always confirm against the owner’s manual or workshop data for the exact variant, and have the level set using the correct temperature‑based procedure.
