Hello, i'm having a problem with my car listed above, when I switch from P to D or from D to R it does like a shaking movement and when I see the engine it moves when I shift the gears. I was told from a friend it could be the motor mounts but which one? How can I check them? It could be another thing besides motor mounts? Please help me. Thank you

You are correct that this is most likely a mount issue. I am attaching the info that you need to replace these mounts.

You will want to watch the engine when you are having someone shift gears so that you can see which mount appears to be flexing. Then this is the mount we need to replace.

Here is a guide that will help as it is similar:

Hello, I'm Danny,

You're vehicle actually has 3 different motor mounts. The best way to test if you have a broken motor motor is to have a helper but you can do it by yourself. With the engine running make sure the emergency brake is on and your foot is fully depressing the brake pedal. Quickly give short burst on the gas pedal. If a motor mount is broken by giving those burst of gas you will see the engine lift up and down in the location of the broken mount. I you have a helper they will be able to see this with the hood open. If you are doing this yourself just peek between the opening of the cowl are and the bottom edge of the hood. This actual does work as crazy as it sounds. I've attached pictures below of what the 3 different mounts look like including the price from AutoZone. Hope this helps and thanks for using 2CarPros.
