Question about transmission

[Paulpt]

I wonder if anyone has experienced this.

I was driving in the city a couple of days back. In two different ocassions, when I came to a full stop, the car started vibrating in a weird way. The best way to describe it is like when you are waiting at a traffic stop and there is a heavy truck on the road and makes the road shake. Actually I thought this was the case but it did it a few times after that.

Again, it does it once it came to a full stop, like if something was still rotating or something.

Has anyone had this same problem? - Thanks for your responses.

It happens to me when I turn on or off the AC.
