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

Information
Radial seal input shaft, Manual gearbox.
Manual Transmission Input Shaft Seal is an OE Match replacement shaft seal designed to fit precisely in the transmission case and maintain a reliable seal around the input shaft under rotational load, temperature variations, and fluid pressure. It prevents transmission fluid leakage at the interface where the input (main) shaft exits the transmission housing - ideal for Porsche 911 (997) manual transmissions.
Fits:
For cars with MANUAL gearbox
Porsche 997.1 Carrera 2 / Carrera 4 - 2005 to 2008
Porsche 997.1 Carrera 2S / Carrera 4S - 2005 to 2008
Porsche 997.2 Carrera 2 / Carrera 4 - 2009 to 2012
Porsche 997.2 Carrera 2S / Carrera 4S - 2009 to 2012
Diagram ref no 1
The input shaft seal creates a tight barrier between the manual transmission housing and the rotating input (main) shaft, preventing transmission oil from leaking out while allowing smooth shaft rotation.
Function:
• Prevents manual transmission fluid from leaking at the input shaft
• Ensures correct retention of lubrication within the gearbox
• Supports smooth, vibration-free shaft rotation
A worn or leaking input shaft seal allows transmission lubricant to escape, lowering oil levels and leading to increased friction, heat, and accelerated gearbox wear. Replacing it with an OE Match seal restores proper lubrication containment, helps protect internal gears and bearings, and reduces risk of costly transmission damage.
When to replace:
• Visible transmission oil leaks at front of gearbox
• Transmission oil level drops without external cause
• After manual gearbox removal/servicing
• When rebuilding or refreshing the transmission
• Preventative maintenance during clutch or drivetrain work
