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

Information
Radial seal input shaft, Manual gearbox.
Manual Transmission Input Shaft Seal is a genuine Porsche OEM part, engineered and approved by Porsche to meet the exact specifications used in factory assemblies. It is a precision-manufactured seal that prevents transmission fluid from leaking at the point where the manual transmission’s input (main) shaft passes through the gearbox housing.
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
This seal creates a hydrostatic barrier between the rotating transmission input shaft and the stationary gearbox housing, preventing transmission oil from escaping while allowing the shaft to spin freely. Proper sealing helps maintain correct fluid levels and protects internal gears and bearings from premature wear.
Function:
• Seals manual transmission fluid at the input/main shaft interface
• Prevents leaks and loss of lubrication
• Maintains consistent gearbox oil levels
• Supports smooth rotation and drivetrain reliability
A compromised input shaft seal can lead to transmission oil leaks, low lubricant levels, and increased friction inside the gearbox, all of which can accelerate wear on gears, bearings, and synchros. Replacing a leaking or worn seal ensures proper sealing, preserves gearbox health, and helps avoid expensive drivetrain repairs down the road.
When to replace:
• Visible manual transmission oil leaks at front of gearbox
• Low gearbox oil level without other external leaks
• During transmission removal or servicing
• When replacing other drivetrain seals to prevent future leaks
• As preventative maintenance with clutch or drivetrain overhaul
