A transmission mount, on the other hand, work with engine mounts to control torque and minimize the vibration transferred to the chassis.It is also the trans mount which keeps linkages in their proper positions.o if you have your car for a couple of years now, have the mounts inspected for signs of failure regularly. And should you need a new engine mount, several stores have them available so it shouldn't be hard to find a replacement.
