Symptoms of a failing Transmission Mount?
Vibrations in the cabin
You remember that whole spiel I did a second ago, about how the transmission mount keeps vibrations from getting into the cabin? Well, you can probably guess that when there are excessive vibrations in the cabin, it might be the result of the transmission mount not doing its job anymore. And your guess would be correct. When the mount breaks down and fails, it will no longer absorb vibrations, which means the thing stuck absorbing the vibrations is…wait for it…you. Not as fun as it sounds. Trust me.
Ahh, everyone’s favorite car problem: a mysterious noise. When your transmission mount begins to malfunction, you’ll notice a loud clunking noise. In general, the noise will occur when you’re accelerating, decelerating, or putting your car into gear. The noise is the result of the transmission mount allowing the engine or transmission to move around, so that’s when you’ll hear it. And it’s not a pretty noise.
Your car has a lot of fluids, which means it can sometimes leak. One of the causes of a leak is a busted transmission mount. This will only be the case if you have a hydraulic mount, which has a liquid center. If the mount is broken, the liquid from the center of the mount may begin leaking out.
Engine and transmission are sagging or moving
If the mount breaks, both the engine and transmission may find themselves moving around more than they should. Do I need to mention that they shouldn’t really be moving around at all? Well, they shouldn’t. But when the mount goes, they’ll suddenly have free reign.
The engine or transmission may be visibly sagging, especially if it’s a front-wheel drive car. Trust your eyes. If it looks funny, it’s probably gonna act funny.
