The Hydraulic Filter, automatic transmission (113 403) removes contaminants from hydraulic or transmission fluid to protect internal components. Replacing a clogged filter restores smooth shifting and reliable hydraulic performance. Use Porza’s smart search to find the correct filter.
A hydraulic filter for an automatic transmission is a filtration component that cleans the transmission fluid by removing dirt, metal particles, and other contaminants. Its function is to ensure clean fluid circulates through the hydraulic system, protecting internal components such as valves, clutches, and the transmission pump, while maintaining smooth shifting and performance.
Key specifications include filtration efficiency (micron rating), flow rate capacity, filter design (internal or external), and compatibility with the specific transmission model. The filter media is typically made from high-quality paper or synthetic materials designed to capture fine particles while allowing proper fluid flow. It must withstand transmission fluid, pressure, and temperatures commonly ranging from -40°C to +120°C.
Replacement is recommended during regular transmission service intervals or when changing the transmission fluid. A clogged or degraded filter can restrict fluid flow, leading to poor shifting, overheating, or increased wear on internal components.
Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the filter matches your transmission system, including size, design, and performance requirements.
Porza supplies high-quality transmission and hydraulic system components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This allows quick and reliable access to essential maintenance parts for both professional workshops and individual users.
If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
