Radial seal input shaft, Manual gearbox. Porsche 997 Carrera 2 / Carrera 4  ❭  99730280700

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
