Z Vector Teleportation Help

Hi, I am a starter at Java and Unity, I wanted to change the z position of my player. But it always says things in the console like ' "position" is not a member of UnityEngine.GameObject. ' Here is (part of) the script:

     if(gameObject.postion.z == (-33)){ 
             transform.gameObject.position == Vector3(-74.28801,30.53975,-1486.8);   //This is the position that the player is teleported to.
     }
 }
