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

• Built to match the original equipment in form, fit and function, this version replicates the original pan’s dimensions, mount points, sealing flange and filter interface.
• Position on Vehicle: Mounted beneath the front of the engine/transmission assembly, forming the lower reservoir of the PDK transmission - replaces the original sump pan and integrated filter housing.
• OEM number: 9P1321359 (sometimes written 9P1-321-359), Supersedes: 9G132102500, 9G132102501, 9G132112500.
• Applications: Ideal when original transmission sump/pan is cracked, leaking, or damaged; when filter cannot be serviced separately; or when performing a full transmission service in a vehicle with the PDK gearbox.
The transmission oil pan plays a vital role in PDK gearbox health: it contains the fluid reservoir, houses the filtration screen (in many cases cannot be serviced separately) and helps maintain correct fluid volume and cleanliness. If this pan is cracked, leaking, has a damaged filter, or if internal sludging occurs, you can experience poor shifting, fluid foaming, overheating or even internal gearbox damage. Replacing it with a fresh unit restores correct fluid containment, filter function and protects your transmission investment.
When and why to replace:
• Observable fluid leak or seepage from the transmission sump/pan flange.
• Transmission service interval reached where OEM recommendation is to replace pan and internal filter (especially in PDK units)
• After front-end impact or corrosion has damaged pan or flange.
• During major transmission or clutch overhaul when access is already available.
• Vehicle showing rough or inconsistent shifting, temperature rise, or internal transmission warnings.

Transmission Oil Filter – Part ref No. 986 307 403 00
This precision-engineered transmission oil filter is designed to keep your Porsche’s gearbox operating smoothly. It traps harmful contaminants before they can enter the transmission’s valve body and fluid passages, protecting sensitive components from wear and damage. By maintaining clean transmission fluid, it helps prevent shifting problems such as delayed engagement, harsh gear changes, and overall performance decline.

A transmission oil pan and service kit designed to match the quality and fitment of Porsche original equipment. It is a comprehensive kit used during routine transmission maintenance on select Porsche 987 Boxster/Cayman, 997 Gen 2, and 991 models with the 9P1 / 9G3 / 9A1 transmission designation. This kit provides all the essential components needed to properly service the transmission oil pan area and maintain correct sealing and lubrication.
This kit is ideal for routine transmission fluid and filter service, including full oil pan removal and reinstallation, especially when performing a major service or troubleshooting transmission fluid contamination or leaks.
The transmission oil pan service kit includes carefully selected components to assist with proper drainage, sealing, and refilling of the transmission system. During service, the transmission oil pan is removed to replace the fluid and filter media, and often to inspect for wear debris or contamination.
Components in the kit help:
• Seal the oil pan to the gearbox to prevent fluid leaks
• Replace the internal filter or screen (if included)
• Restore correct torque and sealing surfaces when reassembled
Regular transmission service is integral to preserving gearbox performance and longevity. Over time, transmission fluid degrades and filters can become restricted, which can lead to:
• Harsh or delayed shifting Increased internal wear
• Overheating or irregular gearbox behaviour
• Fluid leakage due to aged gaskets

Common Issues
Many engine oil pans, this transmission oil pan do require a gasket. Leakage Problems: Transmission fluid leaks are the most frequent issue—often from worn or degraded sealant or pan warping.
Ensure bolts are replaced and torque-tightened correctly—typically to around 10.5 ft-lb in a crosshatch pattern—to maintain even sealing pressure.
Warping/Torque Loss: Overheating or repeated torque cycles may cause minor warping, leading to fluid seepage—even if the sealant is properly applied.
Corrosion Potential: Even with rust-resistant coating, the steel construction can become susceptible to corrosion over time, especially around edges or mounting surfaces exposed to moisture.
