Wesfil Australia Pty Ltd sources its air, oil, fuel, and cabin filters from quality-assured providers who produce to fulfill the application's performance criteria. Just like oil is the lifeblood of an engine, transmission fluid must be free of hazardous pollutants in order for your car's gearbox to work properly. Transmission fluids live a difficult existence under pressure and heat, and if any debris or contaminant is not filtered out, damage to transmission components can occur, which can not only leave your car unusable, but are also generally costly to repair. Wesfil's transmission filter lineup includes, depending on the application, not only the transmission filter itself but also the replacement pan gasket and any seals or related items required to complete the job.
