bud. I would try Marvel Mystery Oil or Risolone before trans fluid for a gentle cleaning. Run this for a while and change your oil with a good filter. I recommend using a Mopar filter. These engines are sensitive and pretty high tech and will not tolerate neglect. Since your engine only makes noise when cold it could be the filter also, hopefully nothing more serious. What kind of oil and filter have you been using? At what interval? Hope this helps.
