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.

Oil pan & Gearbox oil filter with oil kit.
This is the Tiptronic transmission oil pan (sometimes referred to as a “gearbox oil pan”), responsible for holding transmission fluid and forming a seal between the transmission’s housing and the fluid reservoir. Made from standard steel, designed to match OEM specifications for fitment and clearance. It features a rust-resistant surface coating and is built to remain warp-free for a durable, secure seal.

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.

OEMatch Gearbox Sump / Oil Pan — Durability, Sealing, Performance
For Porsche models, OEMatch gearbox sumps and oil pans are chosen to support transmission servicing, leak repair and reliable oil management. Typical uses include routine maintenance, gearbox rebuilds and restoration work where correct fluid containment, cooling and access to drain or filter points are required.
Understanding OEMatch Gearbox Sump / Oil Pan
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original gearbox sump / oil pan. OE (Original Equipment) refers to parts matching original specifications for the gearbox sump / oil pan and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM gearbox sump / oil pan engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. The sump collects and circulates gearbox oil, provides a location for the drain plug and any filter, and helps dissipate heat from transmission fluid.
Benefits Include
- Restores secure fluid containment and reduces the risk of leaks
- Improves oil circulation and transmission cooling
- Provides correct mounting for drain plugs and any filter during servicing
Why Gearbox Sump / Oil Pan Wear and Fail
- Impact or abrasion from road debris causing dents or cracks
- Corrosion or pitting that degrades sealing faces and fastenings
- Damaged threads, worn drain plugs or failed gaskets and seals
The Importance of Replacing with OEMatch Gearbox Sump / Oil Pan
Replacing a damaged or leaking sump prevents fluid loss and overheating that can cause premature gearbox wear and impaired hydraulic operation. A correctly sealed and fitted sump supports reliable shifting and protects internal gears, bearings and seals; renewing drain hardware and gaskets during installation reduces the chance of repeat leaks.
Advantages
- Corrosion-resistant materials and robust construction
- Precision sealing surfaces to reduce leak risk
- Fits original mounting points and clearances for easy installation
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new sealing hardware where specified and check for leaks after initial running.
