3D Collision with Transform.Translate

I'm using transform.Translate as well as a Character Controller for my 3D player and a rotating camera controlled by the mouse. The movement for the character works fine as long as I use transform.Translate for the movement and Character.Move for the jumping. The CharacterController doesn't work well for movement because it isn't relative to the camera. Is there anyway I can make collisions with the world while using transform.Translate or is there another solution to movement while still being relative to the camera?

Here is my code so far

 //Player 1 
 var gravity    : float     = 20.0;                                                            //set gravity variab;e
 var hopValue : float     = 0.0;                                                            
 var moveSpeed : float     = 5.0;                                                            //set movement speed
 var jumpSpeed : float    = 10.0;                                                            //set jump height
 var velocity : Vector3    = Vector3.zero;                                                    //set velocity variable for 3d movement
 var FPcamera : GameObject;                                                                //define first person camera
 var TPcamera : GameObject;                                                                //define third person camera
 var startPos : Transform;                                                                //define start position for player
 
 
 function Start(){                                                                        //starting function called when player is instantiated
     FPcamera.active = true;                                                                    //activate first person camera
     TPcamera.active = false;                                                                //deactivate third person camera
 }
 function Update () {                                                                    //constantly updated function called every frame
     var controller : CharacterController = GetComponent(CharacterController);                //define character controller from the collision body
     
     var transLR : float = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;            //define left and right movement by the horizontal axis keys
     var transFB : float = Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime;            //define forward and backward movement by the vertical axis keys
     
     if(controller.isGrounded){                                                                //if player is on the ground
         if(Input.GetButton("Jump")){                                                            //if pressing the jump button
             velocity.y = jumpSpeed;                                                                    //move up by jump speed
         }
     }
     transform.Translate(transLR, 0, transFB);                                                //move by the left, right, forward, and backward movements

     }
     transform.Rotate(0,Input.GetAxis("Mouse X") * 5, 0);                                    //rotate body based on mouse x axis    
     Screen.lockCursor = true;                                                                //lock the cursor on the screen
