A damaged or incorrect bracket can cause excessive drivetrain movement, vibration, knocking, poor gearbox alignment or difficulty fitting related transmission mount components. Replacing it with a Genuine Porsche OE gearbox bracket helps restore correct factory transmission support and mounting position.

When to Replace This Part
•   If the original gearbox bracket is cracked, bent or damaged
•   During gearbox mount, transmission support or carrier replacement
•   If there is excessive gearbox or drivetrain movement
•   If vibration, knocking or movement is traced to the transmission mounting area
•   After accident damage or chassis/drivetrain repair
•   If mounting points or bush areas are worn, distorted or corroded
•   During gearbox removal, refitting or major transmission repair
•   When restoring the vehicle with correct OE Porsche hardware.

Where It Fits on the Car
This bracket fits in the rear drivetrain / transmission mounting area. It forms part of the gearbox support and transmission mount assembly, helping secure the transmission to the vehicle structure.

Gearbox Silencer Block.
The OE Match Gearbox Silencer Block is a high-quality replacement mounting component designed to isolate and dampen vibration and noise generated by the gearbox and drivetrain. Installed between the transmission assembly and vehicle mounting points, the silencer block helps absorb drivetrain movement and reduce the transmission of vibration into the chassis and passenger compartment.

Manufactured to OE specifications using durable rubber and metal construction, this replacement silencer block restores the original levels of comfort, refinement and drivetrain support. It is an ideal replacement for worn, cracked or deteriorated original mounts commonly found on ageing Porsche vehicles.  

What This Product Does:

• Isolates gearbox and drivetrain vibrations from the chassis.
• Reduces transmission noise entering the passenger compartment.
• Supports the gearbox while allowing controlled movement.
• Helps maintain correct drivetrain alignment.
• Minimises shock loads during acceleration and gear changes.
• Improves driving comfort and refinement.

Symptoms Of Wear Or Failure:

• Increased vibration felt through the cabin.
• Excessive drivetrain movement during acceleration or deceleration.
• Clunking or knocking noises when changing gear.
• Harsh engagement during gear shifts.
• Visible cracking, splitting or deterioration of the rubber mount.
• Sagging or misalignment of the gearbox assembly.
• Increased transmission noise within the vehicle.
• Premature wear of surrounding drivetrain components.

Why Replacement Matters:

• The gearbox silencer block is continuously exposed to drivetrain torque, engine vibration, road shock, heat and age-related deterioration. Over time, the rubber element can harden, crack or separate from its metal mounting surfaces, reducing its ability to absorb vibration and support the transmission correctly.
• A failed silencer block can allow excessive gearbox movement, leading to increased vibration, drivetrain noise and additional stress on transmission mounts, couplings and related components. If left unresolved, excessive movement may contribute to accelerated wear throughout the drivetrain system.

HD Transmission / Gearbox Mount Bush.
Enhance drivetrain control and shifting precision with the HD Transmission / Gearbox Mount Bush.
Engineered for Porsche 964 and 993 C2 models, this heavy-duty mount replaces the soft factory bushing with a stiffer, high-durometer rubber compound that improves gearbox stability and alignment under load.

Fits:

• Porsche 964 (911) C2 1989-93
• Porsche 993 (911) C2 1994-97

Diagram Ref No 23

What This Product Does:

• Support & Locating Function - The mount holds the gearbox housing in its proper position relative to the chassis. It resists movement under torque, acceleration, braking, or other loads.
• Vibration Damping / Noise Isolation - The rubber or elastomer absorbs vibration and noise from the transmission so that it doesn’t transmit harshly into the cabin.
  
• Control Twist / Deflection Under Load - Under torque or rapid load changes, the transmission tends to twist or shift slightly. A good mount restrains that movement, preserving alignment and reducing strain on connected parts (driveshafts, couplings, etc.).
  
• Maintain Drivetrain Geometry - By limiting excessive movement, it helps maintain the correct angles and alignment of drivetrain components, which is important for durability and performance.
  
  

Symptoms Of Worn Or Weak Mounts:

• Thumping, clunking, or bangs when shifting gears, accelerating, or decelerating
  
• Excessive vibration or harshness in the cabin, especially at idle or under load
  
• Gear lever play or misalignment under load
  
• Delayed or vague shift feel, due to movement or flex in the mount
  
• Wear on drivetrain components, as undue movement induces stress in shafts, joints, couplings
  
• Mount failure (cracks, splitting, excessive deformation) visible on inspection
  
  

Why The HD Version Upgrade Matters:

• Tighter drivetrain response — less flex means more immediate reaction during shifting or throttle transitions
  
• Improved alignment consistency — better control of the gearbox position helps preserve ideal geometry under stress
  
• Reduced noise and slop — sharper operation, less perceptible movement
  
• Better durability — stiffer (HD) rubber resists aging, compression set, and breakdown better than older soft rubber
  
• Balanced vibration control — while firmer than stock, remains less harsh than fully solid mounts, striking a good compromise for street / performance use
  
• Straightforward replacement — fits into the stock bracket, so installation is simpler than aftermarket custom mounting
