Unity 3D C# - OnControllerColliderHit Position

Hi Im trying to move an object and keep its rotation which the slope of the terrain, for example, when the object goes up a hill, the object rotation changes with it and doesn't stay vertical, this is my code which are failed attempts.

  void OnControllerColliderHit(ControllerColliderHit hit) {
         //myAng = Vector3.Angle(Vector3.up, hit.normal); //Calc angle between normal and character
         //transform.rotation = Quaternion.FromToRotation(Vector3.up, hit.normal) * transform.rotation;
         //transform.Rotate(Vector3.up * Time.deltaTime * 6f);
 
         //transform.rotation = Quaternion.Euler(new Vector3(hit.transform.rotation.x, transform.rotation.y, hit.transform.rotation.z));
 
         transform.rotation = Quaternion.LookRotation(new Vector3(hit.transform.position.x, transform.rotation.y, hit.transform.position.z));
     }
