What are transmission rubber mounts?

Transmission rubber mounts are isolators that attach the transmission to the chassis of the car. They are made of a durable rubber or polyurethane compound that is designed to absorb vibration and noise. Transmission rubber mounts play two important roles:

Dampening vibration and noise: The transmission is a complex piece of machinery that produces a lot of vibration and noise during operation. Transmission rubber mounts help to absorb these vibrations and noises, preventing them from being transmitted to the passenger compartment.

Supporting the weight of the transmission: The transmission is a heavy component, and transmission rubber mounts help to support its weight and distribute it evenly across the chassis.

Why are transmission rubber mounts important?

Transmission rubber mounts are important for several reasons:

To prevent transmission damage: Transmission rubber mounts help to protect the transmission from vibration and shock damage. When transmission rubber mounts go bad, they can allow the transmission to move too much, which can lead to damage to the gears and other internal components.

To improve ride quality: Transmission rubber mounts help to absorb vibration and noise from the transmission, which improves ride quality for passengers.

To extend the life of the transmission: By protecting the transmission from vibration and shock damage, transmission rubber mounts can help to extend its lifespan.

Signs of wear and tear

Transmission rubber mounts are subject to wear and tear over time. Some of the common signs that your transmission rubber mounts may need to be replaced include:

Excessive vibration: If you notice excessive vibration in the steering wheel, floorboard, or passenger compartment, especially when accelerating or shifting gears, it may be a sign that your transmission rubber mounts are worn or damaged.

Clunking noises: If you hear clunking or banging noises coming from the transmission area, it may be a sign that your transmission rubber mounts are worn or damaged.

Leaking fluid: If you see fluid leaking from the transmission area, it may be a sign that your transmission rubber mounts are worn or damaged and have allowed the transmission to move too much.

Difficulty shifting gears: If you have difficulty shifting gears, it may be a sign that your transmission rubber mounts are worn or damaged and have allowed the transmission to move too much.

Replacement procedures

Replacing transmission rubber mounts is a relatively simple job, but it’s important to follow the manufacturer’s instructions carefully. If you’re not comfortable doing the job yourself, it’s best to have it done by a qualified mechanic.

 Here is a general overview of the replacement procedure:

  • Park the car on a level surface and engage the parking brake.
  • Block the rear wheels to prevent the car from rolling.
  • Raise the front of the car using a jack and support it with jack stands.
  • Locate the transmission rubber mounts. They are typically located on the front, rear, and sides of the transmission.
  • Remove the bolts that secure the transmission rubber mounts to the transmission and the chassis.
  • Remove the old transmission rubber mounts and inspect them for signs of wear and tear.
  • Install the new transmission rubber mounts and tighten the bolts to the manufacturer’s specifications.
  • Lower the car and remove the jack stands.
  • Test drive the car to ensure that the transmission rubber mounts are working properly.

Conclusion

Transmission rubber mounts are important components of your car that play a vital role in absorbing vibration and noise, supporting the weight of the transmission, and preventing transmission damage. If you notice any signs that your transmission rubber mounts may need to be replaced, it’s important to have them inspected and replaced by a qualified mechanic as soon as possible.

Additional tips

It’s important to replace all of the transmission rubber mounts at the same time to ensure an even distribution of weight and vibration absorption.

When choosing new transmission rubber mounts, be sure to select high-quality parts from a reputable manufacturer.

It’s also a good idea to have your transmission inspected by a qualified mechanic before and after replacing the transmission rubber mounts. This will help to ensure
