thank you very much

When I'm waiting at a traffic light or start in place, the engine vibrates a lot when it's in D gear, but it's normal in P and N gears. Is this a problem with the gearbox or the engine mat?

Why doesn't my car have No. 32 parts, only No. 30 and No. 31? I bought a used car, maybe the original owner removed the No. 32 shock absorber seat.

As shown in the figure

How do I upload pictures?

My Kizashi's left rear suspension top mount is cracked. I checked the suspension diagram, and parts 30/31 and 32 are shown as two separate components. Why does my car seem to have only part 30/31? Are there differences in the chassis for different configurations of the Kizashi?
