What This Product Does:
- Securing the Transmission - It keeps the transmission firmly in place, resisting movement under torque, acceleration, or deceleration.
- Absorbing Vibration & Noise - The rubber or elastomer element isolates drivetrain vibrations so they don't transmit harshly into the cabin.
- Controlling Movement / Deflection - Under load, transmissions tend to twist or shift slightly. A stiffer mount reduces that movement, improving shift feel, drivetrain alignment, and response.
- Maintaining Drivetrain Geometry - By limiting transmission motion, it helps preserve correct angles and alignment of drive shafts, couplings, and linkage.
- Clunks or thuds when shifting or applying torque
- Movement or slop in the transmission under load
- Delays or vagueness in shifts due to misalignment
- Excess vibration or drivetrain shake in the cabin
- Wear or stress on driveline components (e.g. drive shafts, joints)
- The transmission might feel “loose” under acceleration or deceleration
Why Upgrading Matters:
- Improved Shift Feel & Precision - A stiffer mount reduces movement that can dull shift quality or introduce slack.
- Better Drivetrain Alignment Under Load - Less motion keeps the transmission geometry stable, which protects driveshafts, joints, and couplers.
- Sharper Response - With less flex, the car responds more directly to throttle inputs without drivetrain “lag.”
- Balance of Comfort and Control - The HD rubber design offers more rigidity than stock but isn’t as harsh as solid mounts, so you still retain usable vibration isolation.
- Durability - A stiffer compound is more resistant to deformation, aging, oil, and heat, giving longer service life.
- Cost-Effective Upgrade - If the original bushing is degraded, installing an HD version is often a worthwhile performance upgrade.
