This part is known as the transmission mount , transmission base , or transmission support . It is a sturdy metal piece encased in a thick layer of rubber or other insulating material. This mount is installed between the transmission (gearbox) and the chassis of the JAC GS4 (2018-2022 models).
Its primary function is to support the weight of the gearbox in its correct position and ensure that vibrations and noise generated by the transmission are isolated and prevented from entering the vehicle's cabin. It also limits excessive gearbox movement during acceleration and deceleration. This TAC PART part is designed to be an identical replacement for the original part.
If the driver feels a severe shudder and vibration in the steering wheel or the car's interior, especially when in park (D or R), or if he hears a loud "click" or "knock" sound when starting or changing gears, these are typical signs of damage or wear of the rubber in the gear and engine mounts.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
