OE Match replacement oil strainer for the Tiptronic automatic transmission fitted to the Porsche 968. This oil filter sits inside the Tiptronic transmission sump and screens contaminants from the automatic transmission fluid before it circulates through the gearbox. It ensures correct fluid delivery to hydraulic components while maintaining compatibility with the original sump, gasket, and sealing surfaces. It is an essential service item during routine ATF changes or gearbox maintenance.
Fits:
Porsche 968 1992 - 1995 Tiptronic
Diagram ref no 4
The filter traps debris, wear particles, and contaminants suspended in the transmission fluid, helping protect the valve body, pump, and internal hydraulic circuits. Clean fluid flow supports smoother shifting and consistent transmission performance.
Function: Installed within the transmission oil pan, the oil strainer allows unrestricted ATF flow while preventing harmful particles from entering sensitive components. Its OE Match construction ensures proper sealing, correct positioning, and reliable filtration throughout service intervals.
Over time, gearbox oil filters can become restricted by debris and degraded fluid residues. A clogged or compromised filter can reduce hydraulic efficiency, contribute to poor shift quality, and accelerate internal wear. Replacing the filter with an OE Match unit during servicing helps maintain proper fluid flow, protects internal components, and supports long-term transmission reliability.
When to replace:
• During Tiptronic ATF and sump service
• When transmission fluid shows contamination or debris
• As part of gearbox maintenance or repair
• If shift quality becomes rough or inconsistent
• Preventive replacement on higher-mileage vehicles
