Oil Strainer (Automatic Transmission)
Genuine Porsche Original Equipment (OE) oil strainer (transmission oil filter) designed for use in the automatic transmission/gearbox of compatible Porsche models. This oil strainer fits inside the automatic transmission fluid circuit to screen out contaminants and particles from the transmission oil, helping protect valves, pumps, and internal gears from premature wear.

Fits:
For cars with Automatic transmission
Porsche 924 1976 - 1985
Porsche 924 S 1986 - 1988
Porsche 944 1982 - 1989

The transmission oil strainer filters out metal shavings, debris, and other contaminants from the transmission’s fluid before it reaches critical hydraulic components. This helps the gearbox operate smoothly, reduces friction and wear on moving parts, and extends service life.

Function: Installed within the transmission’s sump or oil circuit, the strainer traps foreign particles and prevents them from circulating through the gearbox. By maintaining cleaner oil flow to the pump and valve body, it supports consistent hydraulic pressure, smooth shifting, and reduced risk of internal damage.

Over time, transmission oil strainers can become clogged with debris, reducing fluid flow and increasing wear in the transmission’s internal components. A worn or restricted strainer limits hydraulic performance, can lead to rough shifting or overheating, and may shorten transmission life. Replacing restores correct filtration, maintains fluid cleanliness, and protects the gearbox’s mechanical and hydraulic systems.

When to replace:
•  During automatic transmission service or fluid change
•  When transmission exhibits sluggish or rough shifting
•  After extended mileage or high-heat operation
•  If transmission fluid shows signs of contamination or debris
•  With intermediate servicing at factory-recommended intervals
