Bentley Bentayga V8 Transmission Gearbox Mount Pair 4M0399201G 4M0399202G

Left & Right Transmission Gearbox Mount Pair for Bentley Bentayga V8

Restore smooth drivetrain support with a matched left-and-right gearbox mount pair for Bentley Bentayga V8 applications. Reference numbers 4M0399201G and 4M0399202G, these hydro-mount assemblies support the transmission while isolating vibration and controlling drivetrain movement under acceleration, deceleration and gear changes.

Designed for Powertrain Refinement

The Bentayga combines substantial torque with a luxury-focused chassis, placing high demands on its transmission mounts. Internal fluid loss, rubber deterioration or mount collapse can increase vibration, thumps and drivetrain movement. Replacing both sides together restores balanced support across the gearbox.

Key Features

• Application: Bentley Bentayga V8 petrol and V8 diesel compatible applications

Installation Guidance

Support the transmission securely before removing either mount. Replace one side at a time where practical, align all brackets without forcing the assembly and tighten fasteners using the correct workshop torque sequence. Inspect engine mounts and surrounding cross-member hardware while the vehicle is raised.
