The transmission mount may be a small component. But its impact on the vehicle’s performance is undeniable. This component stays responsible for several things including- isolating the unwanted vibration from the passenger cabin, supporting the weight of the transmission. Continuous pressure on the transmission eventually causes the rubber of the mount to deteriorate. This small stuff may collapse without showing any symptoms of external damage. Apart from knowing the symptoms, you should do inspection of the mount on a regular basis so that you can prevent unnecessary complications caused due to a faulty mount.
