What This Product Does:
- Support and Mount the Transmission - They hold the gearbox (transaxle) in place relative to the chassis, keeping it aligned and preventing undesired motion.
- Absorb Vibration & Isolate Noise - The bushings dampen transmission vibration and drivetrain noise, improving comfort.
- Control Drivetrain “Slop” / Play - Stiffer bushings reduce the amount of twist or movement under torque load, minimizing driveline lash or unwanted movement when accelerating, shifting, or off the throttle.
- Maintain Geometry & Alignment - Properly mounted gearbox prevents shifting of driveline angles, which helps protect CV joints, driveshafts, and reduces undue stress elsewhere.
- Clunking, knocking, or banging noises during shifts, on throttle application, or when decelerating
- Driveline lash / slop — a sensation of delay or “slack” before power transfer
- Increased vibration or harshness felt in the cabin, especially under load or gear changes
- Gearbox movement — the transmission may move or twist noticeably when revs / torque change
- Wear on adjacent components — e.g. CV joints, driveshafts, differential support bearings may see accelerated wear
- Restores Sharpness & Responsiveness — by eliminating soft or worn mounts, the drivetrain becomes more responsive and direct.
- Reduces Noise, Vibration & Harshness — a proper bushing absorbs and isolates vibration better than degraded old rubber.
- Protects Other Drivetrain Parts — reduces stress on CV joints, couplings, differential mounts due to movement or misalignment.
- Preserves Safety & Durability — under high torque loads (e.g. hard driving), a weak mount can twist excessively and cause damage.
- Better Handling Feedback — with less transmission movement, throttle transitions and engine braking feel more controlled and precise.
