Parenting instantiated particle system

Hi everyone - I have a particle system that is instantiated when another object collides with it - however I want it to move with the parent it is a child to. This is the current code I have, but it doesn't seem to be following the parent, just stays in the place it was instantiated. Thank you!

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class ParticleInstantiate : MonoBehaviour {

public GameObject transmissionParticles; public GameObject parentObject;

void OnCollisionEnter (Collision coll) { if (coll.collider.CompareTag ("Transmission")) { Transmit (); Debug.Log("collided"); } }

void Transmit () { GameObject transmission = Instantiate(transmissionParticles, transform.position, transform.rotation); transmission.GetComponent().Play(); transmissionParticles.transform.parent = parentObject.transform; }

}
