Radial shaft seal torque converter. Porsche 955 Cayenne / 957 Cayenne

95532124302

Product Information

Radial shaft seal torque converter 43,65 x 62,1 x 7,7
This Porsche Genuine OE Radial Shaft Seal is a precision-engineered transmission oil seal designed for use within the automatic gearbox (Tiptronic) torque converter assembly. This component is commonly referred to as a torque converter seal or transmission input shaft seal.

Fits:
Porsche 955 Cayenne 2003 - 2006
Porsche 957 Cayenne 2007 - 2010

Diagram ref no 5

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.

Radial shaft seal torque converter. Porsche 955 Cayenne / 957 Cayenne

95532124302/1

Product Information

Radial shaft seal torque converter 43,65 x 62,1 x 7,7
This radial shaft seal is a precision-engineered OE match replacement used in the automatic transmission (Tiptronic) system of Porsche Cayenne 955 and 957 models. Installed at the torque converter interface, it ensures a tight seal around the rotating shaft. Manufactured to exact factory specifications, the seal features precise dimensions (43.65 x 62.1 x 7.7 mm) for a perfect fit and reliable performance.

Fits:
Porsche 955 Cayenne 2003 - 2006
Porsche 957 Cayenne 2007 - 2010

Diagram ref no 5

This seal prevents automatic transmission fluid from leaking at the torque converter shaft interface. It also blocks dirt and contaminants from entering the transmission, helping to preserve internal components and maintain smooth operation.

Function
• Seals the interface between torque converter and transmission housing
• Prevents transmission fluid leaks under pressure
• Protects internal components from dirt and contaminants
• Maintains proper lubrication within the transmission system
• Supports smooth and efficient drivetrain operation

A failing torque converter seal can lead to transmission fluid leaks, which may result in poor shifting, overheating, and internal damage. Because the seal operates under constant heat and pressure, it can harden or wear over time.

Replacing it ensures proper sealing, protects the transmission, and prevents costly repairs.

When to replace
•   Visible transmission fluid leaks (especially around bellhousing area)
•   Signs of low transmission fluid levels
•   During torque converter or transmission servicing
•   Evidence of seal wear, hardening, or cracking
•   Slipping gears or irregular transmission performance

About Flywheel / Torque

Porsche Flywheels & Torque Converters | Smooth Power Transfer & Engine Balance

Flywheels and torque converters are vital components in your Porsche’s drivetrain, ensuring smooth power transfer from the engine to the transmission. The flywheel provides rotational balance and stores kinetic energy for manual gear changes, while the torque converter in automatic models performs a similar role — transferring engine torque hydraulically for seamless acceleration.

At Design911, we supply precision-engineered flywheels and torque converters designed to meet or exceed original performance specifications. Each component is manufactured from high-grade materials, ensuring strength, balance, and reliability under all driving conditions. Whether you’re restoring a classic 911 or maintaining a modern PDK-equipped Porsche, our range provides the quality and performance your drivetrain demands.

What Do Flywheels & Torque Converters Do?

Both components play critical roles in the performance and drivability of your Porsche, acting as torque-transfer systems between the engine and gearbox.

Flywheels (Manual Transmissions):
Store rotational energy to maintain engine smoothness. Provide a friction surface for clutch engagement. Aid in gear transitions by balancing engine speed and torque.

Torque Converters (Automatic Transmissions):
Transfer torque through fluid dynamics between engine and gearbox. Enable smooth gear shifting without clutch operation. Multiply torque for efficient acceleration and smoother driving.

Together, they ensure seamless operation, smooth starts, and optimal power delivery from engine to transmission.

Why Do Flywheels & Torque Converters Fail or Wear Out?

Over time, both flywheels and torque converters experience wear due to high rotational forces, friction, and heat cycles.

Common Causes of Failure Include:

Heat damage or warping from clutch slippage (flywheels).
Cracked or worn ring gear teeth affecting starter engagement.
Fluid contamination or internal seal leaks (torque converters).
Bearing wear leading to vibration or imbalance.
Excessive torque or misalignment from modified engines.

Symptoms of failure may include clutch chatter, transmission shudder, vibration during acceleration, or slipping during gear changes. Ignoring these signs can lead to further drivetrain damage.

Why Replace your Flywheel or Torque Converter?

Replacing worn flywheels or torque converters restores smooth torque delivery, reduces vibration, and ensures reliable clutch or transmission performance. Upgraded lightweight flywheels improve throttle response, while performance torque converters enhance acceleration and drivability.

Key Benefits:

Restores smooth engine-to-transmission power delivery.
Eliminates vibration, slippage, and engagement issues.
Improves clutch or automatic transmission performance.
Balances rotational mass for smoother idling and shifting.
Available in lightweight or performance designs for tuned Porsches.
Ideal for clutch replacement, transmission rebuilds, or performance upgrades.

It’s strongly recommended to replace the flywheel or torque converter during any major clutch or gearbox service for long-term reliability and balanced performance.

Highlights

Premium Porsche flywheels and torque converters.
Precision-balanced for smooth, vibration-free operation.
Manufactured from high-strength, heat-treated materials.
Available for manual, automatic, and PDK Porsche models.
Enhances drivability, acceleration, and transmission longevity.
Essential for gearbox rebuilds, clutch services, and performance tuning.
