Why Do Transmission Mounts Fail?

Failure Symptoms and What to Do?

Worn transmission mounts can negatively impact vehicle performance. Here are some signs to watch for and necessary actions:

• Excessive movement during gear shifts: May indicate looseness or wear.
• Metal clunking or impact noise: Suggests the mount is broken or deformed.
• Increased vibration: Loss of the mount's shock-absorbing effect can cause vibrations inside the vehicle.
• Misalignment of the transmission: If the transmission is not functioning properly, the mounts should be checked.

Causes of Transmission Mount Failure

• Material fatigue over time: Rubber and metal components may wear out.
• High torque and impacts: Transmission loads and shifts can strain the mounts.
• Exposure to oil and chemicals: Can damage the rubber structure.
• Extreme heat and temperature fluctuations: May cause hardening and cracking of the mounts.

Solutions and Maintenance Tips

• Use OEM-standard parts: High-quality mounts last longer.
• Regular maintenance and inspection: Mounts should be checked periodically.
• Prevent fluid leaks: Engine fluids and oils should not damage the mounts.
• Avoid aggressive driving habits: Sudden acceleration can shorten the mount's lifespan.
