The direct-fit replacement transmission / gearbox oil pan assembly designed specifically for the 7-speed PDK dual-clutch gearboxes Porsche models. It sits underneath the transmission housing, captures the fluid reservoir and houses the integrated filter assembly - ensuring proper fluid flow, filtration of internal wear particles and maintaining correct operating temperature and fluid volume.
Fits:

Diagram Ref No. 8, 9 and 10
• 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.
