What This Product Does

The carrier forms part of the transmission support assembly, providing the structural connection used with the gearbox mounting components. It is distinct from the associated mounting bearings, seats and fasteners shown in the assembly diagrams.

Functions

• Supports the gearbox within its mounting assembly.
• Provides attachment points for the associated transmission mounting components.
• Helps maintain the gearbox's installed position when used with serviceable mounts and fixings.

Symptoms of Fault

Clunking as drive is taken up, unusual drivetrain movement, cabin vibration or inconsistent gear selection warrant inspection of the complete support assembly. These symptoms do not establish that the carrier itself needs replacement: mounting bearings, fixings, clutch operation and linkage condition can produce similar complaints.

Why Replacement Matters

Renewing a carrier found to be damaged addresses a structural fault in the gearbox support assembly. Inspect the adjoining mounting components and attachment points during the repair rather than assuming that changing the carrier alone will resolve vibration or shifting concerns. OE Match focuses on Porsche replacement applications, with specification and fitment checks forming part of its component assessment process.

FAQs

Is this the same component as a gearbox mounting bearing?
No. The supplied diagrams identify the carrier and mounting bearings as separate components.

Will replacement cure difficult gear selection?
Not necessarily. Check the clutch, linkage and transmission condition as well as the support assembly before deciding which component requires renewal.

What should be checked before fitting?
Confirm the vehicle year and transmission version, then inspect the related bearings, seats, fixings and mounting points. Do not assume that other components pictured in an assembly diagram are included.
