Application and Function in the Drivetrain

The top holder of the gearbox extension housing in the Ford Focus Mk3 is responsible for precisely positioning the gearbox relative to the body. A correctly selected and installed part:

• stabilizes the gearbox during acceleration, engine braking, and gear changes,
• reduces the transmission of vibrations and noise from the drivetrain to the cabin,
• supports other gearbox mounts, reducing their operational load,
• helps maintain the correct drivetrain geometry, contributing to smooth gear shifter operation.

By preserving the original geometry of the mount, installation is predictable and does not require structural modifications.

Original Ford Gearbox Mount

The presented holder is an OEM part from Ford, meaning it fully complies with the factory mounting points and design parameters intended for the Focus Mk3. An original gearbox and drive mount:

• maintains the stiffness and operating characteristics designed by the manufacturer,
• eliminates the risk of misalignment typical of some aftermarket parts,
• facilitates installation for the mechanic due to predictable fit with existing components.

This solution is particularly recommended for repairs where the repeatability of factory drivetrain operating conditions is crucial.

Condition, Verification, and Preparation for Installation

The part is offered as a used part, which in practice means a favorable compromise between repair cost and maintaining original manufacturing quality. The holder comes from disassembly, thus retaining the factory material and structural specifications intended for this model.

Before installation, a standard workshop procedure is recommended: checking mounting surfaces, threads, and contact points with the body and gearbox. A correctly installed holder allows for restoring proper gearbox support, which is especially important after collisions, gearbox replacements, or other interventions in the drivetrain.

Selection by OEM Number and Technical Support

This gearbox extension housing holder has a dedicated OEM part number and associated interchangeable numbers, facilitating unambiguous identification and selection for a specific Ford Focus Mk3 version. When matching, it is advisable to use the OEM number, service documentation, or VIN verification to avoid errors between different gearbox and body variants.
