Oil strainer. Porsche 924 / 944 with Automatic Transmission  ❭  010325421A

Oil Strainer (Automatic Transmission)
This Transmission Oil Strainer is a high-quality replacement filter designed to replicate the original Porsche automatic transmission oil strainer used on classic 924 and 944 automatic gearbox models. It fits into the transmission’s oil circuit to help maintain clean fluid delivery to pumps and valve bodies. It’s ideal for transmission servicing, rebuilds, or any situation where the original strainer is worn, clogged, or compromised.

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 contaminants such as metal particles, clutch material, and other debris from the automatic transmission fluid before it circulates through the gearbox’s critical components. By helping keep the fluid clean, it supports smoother shifting, better hydraulic performance, and longer transmission life.

Function: Installed inside the transmission oil circuit, this strainer acts as a protective screen that allows transmission fluid to flow while capturing unwanted debris. It helps ensure that the fluid reaching the transmission pump and valve body is free of harmful contaminants that could contribute to wear, sticking valves, overheating, or poor shift quality.

Transmission oil strainers naturally accumulate debris over time. A clogged or worn strainer can restrict fluid flow, increase pump load, and reduce pressure to critical hydraulic circuits - leading to harsh or delayed shifting and accelerated internal wear. Replacing the strainer with an OE Match unit helps maintain proper fluid flow, preserves hydraulic performance, and protects the transmission against premature failure.

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
