Purpose
The engine-gearbox mounting cushion is used for:
* Reducing vibrations transmitted from the engine and gearbox to the car body.
* Reducing noise caused by transmission operation.
* Ensuring reliable coupling between the power unit and the car body.
Design
The automatic transmission engine mounting cushion usually consists of the following components:
*Metal Bracket: Attached to the engine or transmission.
* Rubber or polyurethane insert: Absorbs vibration and noise.
* Metal casing: Protects the rubber insert from damage and external influences.
Types
There are several types of automatic transmission engine mounting cushions:
* Hydraulic: Use hydraulic fluid to absorb vibration.
* Pneumatic: Used air cushions to absorb vibrations.
* Urethane: Made from urethane, which has good damping properties.
* Rubber: Made from rubber, which is also a good damping material.
Replacement
Automatic engine-box mounting pads are usually replaced when the rubber insert wears out or breaks. Signs that replacement is needed include:
* Excessive vibration when starting the engine or shifting gears.
* Increased noise level when the engine is running.
* Increased fuel consumption.
* Transmission slipping.
Important! Replacement of automatic engine-box mounting cushions should only be performed by a qualified mechanic.
