Gearbox Mount (Transmission Mount)
A gearbox mount holds the transmission to the body or subframe and dampens vibrations.
What is Gearbox Mount (Transmission Mount)?
It works together with the engine mounts. Worn mounts cause knocks when shifting or pulling away. Some use hydraulic damping. A worn mount can let the gearbox move enough to make gear selection vague. Mechanics check mounts by watching the engine and gearbox while shifting between drive and reverse with the brakes held.
How it works
Rubber between metal brackets absorbs movement.
Why it matters for your car
Torn mounts can cause judder and gear shift problems. Inspect all mounts together.
