This part is designed to limit excessive movement of the upper transmission under load by providing additional stability to the mount from filling excessive voiding in the original mount. This insert is very easy to fit and is a fast way to improve shift feel and performance. If fitting this to a diesel engined vehicle, an increase in noise and vibration is to be expected. This should be considered as a performance upgrade.
