What This Product Does

The mounting connects the gearbox to its supporting structure, allowing controlled movement while keeping the transmission located. It helps absorb vibration generated by the drivetrain and limits displacement as torque loads change.

Functions

• Supports and locates the gearbox.
• Helps isolate drivetrain vibration from the body.
• Restrains excessive transmission movement under load.
• Helps maintain alignment with associated drivetrain and gear-selection components.

Technical Details

• Part number: 99737505501.
• Brand: Porsche.
• Component: gearbox mounting, also known as a transmission mount.
• Supplied application: 997 (911) MK1, 2005–2008.

Symptoms of Fault

• A knock or clunk as drive is taken up or the load changes.
• More vibration transmitted into the cabin.
• Unusually large movement of the drivetrain.
• A less precise gear-selection feel.
• Visible deterioration or deformation of the mounting.

These signs are not conclusive on their own. Inspect the gearbox mounting, engine mounts and associated components before deciding which part requires renewal.

Why Replacement Matters

A deteriorated mounting can allow unwanted gearbox movement and transmit additional vibration. Replacing a confirmed faulty mount helps restore controlled transmission support and reduces movement that may place strain on neighbouring components. This genuine Porsche component is intended for repairs retaining the original vehicle specification.

FAQs

Will replacing the mounting cure crunching gears?
Not necessarily. Clutch or synchroniser faults can cause gear crunching; a mounting replacement addresses support and movement rather than internal gearbox wear.

Should other mounts be inspected?
Yes. Check the remaining drivetrain mounts for deterioration so that support is assessed as a complete system.

How should compatibility be confirmed?
Match 99737505501 to the vehicle’s VIN, model year and transmission specification before ordering.
