This radial shaft seal forms a tight seal between rotating and stationary components within the transmission, specifically around the torque converter/input shaft area.

Its primary function is to retain automatic transmission fluid (ATF) inside the gearbox while preventing dirt, debris, and contaminants from entering the system.

By maintaining a sealed environment, it ensures proper lubrication and pressure within the transmission.

Functions & Technical Role
•  Fluid sealing: Prevents ATF leakage from the torque converter housing
•  Contamination protection: Stops dirt and debris entering the transmission
•  Pressure retention: Maintains correct hydraulic pressure within the gearbox
•  High-speed sealing: Designed for rotating shafts under load
•  OEM precision: Exact dimensions (approx. 43.65 x 62.1 x 7.7 mm) for correct fitment

Fitment / Position on car
•  Fitting position: Automatic transmission
•  Location: At the torque converter / input shaft interface (bellhousing area)
•  System: Gearbox / torque converter sealing system

Transmission seals operate under heat, pressure, and constant rotation, making them prone to wear over time. A failing seal can lead to:
•  ATF leaks from the bellhousing area
•  Loss of transmission fluid and pressure
•  Slipping or poor gearbox performance
•  Potential transmission damage

Signs such as fluid leaks around the bellhousing often indicate a worn torque converter seal.

Replacing it with a genuine Porsche OE seal ensures proper sealing, protects the transmission, and restores reliable performance.
