What Does a Transmission Mount Do?

Before we get into the juicy stuff—what’s the point of a transmission mount? Well, this part is responsible for holding the transmission in place and absorbing vibrations that come from the engine. Without it, you’d feel all those nasty shakes and vibrations while driving, which would make your car super uncomfortable. Plus, your transmission would move around, which is definitely not safe!

When choosing between an RSX or an SI transmission mount, it’s all about your driving style and what you need from your car. Let’s break it down!


RSX Transmission Mount: Built for Comfort and Durability

The RSX transmission mount is designed for people who want their car to be smooth and reliable. This mount uses stronger materials, like heavier rubber and metal, which make it really sturdy. Here’s why people love it:

  1. Super Durable: The RSX mount is built to last. If you’re using your car for daily driving, commuting to work, or just getting around town, this is the mount for you.
  2. Excellent Vibration Control: The heavier design does a fantastic job of absorbing vibrations. This means when you’re driving, you won’t feel as much shaking or rumbling from the engine.
  3. Comfort-Oriented: Comfort is key with the RSX mount. Since it focuses on absorbing more vibrations, it’s ideal for people who want a smooth ride, especially for longer drives.

So if you want reliability, durability, and a super comfy ride, the RSX transmission mount could be perfect for you!


SI Transmission Mount: Performance and Agility

On the flip side, we’ve got the Civic SI transmission mount. If you’re into performance, racing, or pushing your car to its limits, this mount might catch your eye. Here’s what sets it apart:

  1. Lightweight and Sleek Design: The SI mount uses a lighter frame and is designed more for performance. This doesn’t mean it’s not durable—it’s just built differently, focusing on speed and agility!
  2. Ideal for High-Speed Driving: The SI mount keeps the transmission super stable during aggressive driving, sharp turns, or when you’re driving at high speeds. It’s all about precision and control!
  3. Good Vibration Control, but More for Performance: While it does absorb some engine vibrations, it’s not as focused on comfort as the RSX mount. You might feel more of the engine’s power coming through the chassis.

So, if you’re into performance mods and love driving fast, or if you’re planning on taking your car to the track, the Civic SI mount would be a great fit.


RSX vs SI Transmission Mount: Which is Better?

Alright, now for the big question: which is better, the RSX or SI transmission mount? Well, it depends on how you drive your car!

  • RSX Transmission Mount: This is for the drivers who love comfort and durability. If you use your car daily and want a smooth, quiet ride, go for this one! You’ll enjoy the extra vibration absorption and longer-lasting performance.
  • SI Transmission Mount: On the other hand, if you’re someone who’s all about performance, agility, and high-speed control, the SI mount is calling your name. It’s perfect for those who enjoy fast driving and need more stability at higher speeds.

In a nutshell, if you want comfort, go with the RSX. If you want speed and performance, go with the SI!


Long-Term Benefits of Upgrading Your Transmission Mount

Now, let’s talk about why you should consider upgrading or changing your transmission mount at all. Believe me, this little part can make a huge difference in how your car feels. Here are a few benefits you’ll notice:

  1. Improved Ride Comfort: Whether it’s the RSX or SI mount, having a new transmission mount will instantly reduce vibrations. No more annoying shaking when you’re idling at a red light or accelerating on the highway.
  2. Better Handling and Stability: Upgrading the mount gives you better control, especially during sharp turns or rough terrain. This is a huge win for safety and overall driving experience.
  3. Prolonged Engine Life: When your transmission is secure, it’s less likely to get damaged. A good mount protects your engine and transmission, saving you from costly repairs in the future.
  4. Enhanced Performance: Especially with the SI transmission mount, you’ll get more stability and control during high-speed driving. If you’ve got a need for speed, you’ll feel the difference right away!

Key Differences Between RSX and SI Transmission Mounts

Still feeling stuck? Let’s summarize the key differences between these two mounts so you can make a smart choice:

  • RSX Transmission Mount:
    • Focuses on comfort and durability.

Remember, both mounts do their job, but they’re tuned for different kinds of drivers. The RSX mount is great for people who just want a smooth, reliable ride, while the SI mount is made for those who like to go fast and push their cars a little harder.


How to Install a Transmission Mount
