Diagram Ref No 15

The flange connects the gearbox output to the driveshaft, providing a secure mechanical connection that transfers engine power to the rear wheels.

Confirm gearbox code CG240 or CG270 and check the vehicle VIN before ordering. Other 718 PDK variants may use different flanges.

What Does It Do?

The driveshaft flange is fitted to the transmission output and provides the mounting connection for the driveshaft.

It rotates with the gearbox output, transmitting torque through the driveshaft to the rear wheel.

Why Is It Important?

A secure driveshaft flange helps ensure consistent power transfer and smooth drivetrain operation.

If the flange becomes damaged or worn, it may cause:

• Vibration under acceleration
• Knocking or clunking noises
• Excessive movement at the driveshaft connection
• Damage to associated drivetrain components

Why Does It Fail?

Common causes include:

• Wear around the mounting points
• Repeated drivetrain loads
• Corrosion or damaged contact surfaces
• Loose or incorrectly tightened fixings
• Damage during driveshaft or gearbox repairs

When Should It Be Replaced?

Replace the flange if it is cracked, distorted, excessively worn or has damaged mounting surfaces.

Inspect it during driveshaft replacement, transmission servicing or when unusual drivetrain vibration is present.

Checks & Installation

Check the gearbox output shaft, retaining components, driveshaft mounting surfaces and output oil seal before installation.

Ensure the replacement flange is correctly seated and tighten all fixings to Porsche specifications.

Professional installation is recommended.

Porsche 718 Boxster & Cayman PDK Driveshaft Flanges

The Porsche 718 PDK gearbox uses driveshaft output flanges to connect the transmission to the rear driveshafts, allowing engine torque to reach the wheels.

The driveshaft flange is intended for selected Porsche 718 Boxster and Cayman models equipped with CG240 or CG270 transmissions. Replacing a damaged flange helps restore a secure drivetrain connection and prevent further wear to associated components.
