Does the chugging noise persist when the car is in neutral or park?
When a moving car is shifted into the "Park (P)" gear, the gear itself is still in motion. This causes the gear to make contact with the pawl, which is a part that slides between the teeth of the gear to immobilize it, resulting in a noise. To avoid this, it is important to ensure that the car has come to a full stop before shifting into "Park (P)".
