Why Replace a Worn Transmission Mount?
A deteriorated gearbox mount can allow excess drivetrain movement and transmit more vibration into the body. Replacing the mount restores the designed support relationship between the transmission, subframe and surrounding driveline components.
Installation
Support the transmission securely before removing the original mount. Release the mount fasteners according to the workshop procedure, compare the replacement mounting pattern with the removed component and install the new mount without preloading the rubber isolator. Torque all fasteners to the correct vehicle specification and inspect surrounding drivetrain mounts at the same time.
