What is the function of the transmission rubber mount?
2 Answers
The functions of the transmission rubber mount are as follows: Shock absorption: This component acts as a shock absorber between the transmission and the vehicle frame. It serves to secure the transmission and dampen vibrations during transmission operation, reducing engine shake and providing cushioning. It supports the transmission to prevent vibration damage. Introduction to transmission: The transmission mainly refers to the vehicle's gearbox, which is divided into manual and automatic types. A manual transmission primarily consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic power transmission and gear combinations.
I've been driving for over a decade, and the transmission mount (that rubber cushion under the gearbox) mainly absorbs vibrations and noise while driving, preventing severe transmission movement from directly transferring to the car body. Imagine driving without it—every time you accelerate or shift gears, the entire undercarriage would shake, not just creating annoying noise but potentially damaging other components. Over time, this part can age and crack, especially in older vehicles, making the chassis clunk noticeably over bumps. I recommend checking it every year or two. If you spot cracks or hardening, replace it promptly to avoid bigger issues and unnecessary transmission repair costs.
