Given that you know the transform (I assume it is an array of transforms?) you can use

 var xPos : int = -1;
 var yPos : int = -1;

 for(var i : int = 0; i < array.GetLength(0); i++)
 {
     for(var j : int = 0; j < array.GetLength(0); j++
     {
          if(selectedTransform == array[i, j];
          {
              xPos = i;
              yPos = j;
              break;
          }
     }
     if(xPos != -1)
     {
          break;
     }
 }

And then you can use xPos and yPos! If they return -1, it means the selected transform isn't in the grid (oops);

why do you have that break there?

break tells it "Ok I'm done with this now, don't bother looping through the rest of the iterations. kthxbai!". I've got it there to save time, although you don't techincally need it.

if i where to turn this into a function i would have it return the xPos and the yPos right? and then i would send it my array that i have? thats it?

Kind of? You can't return two values at a time without defining a type which contains them, and you'd need to send it both the array, and the transform you're searching for. I'm really not sure what the context of what you're doing is... (well obviously it's your TD that you are making, but more specifically)
