I am a level 34 Siren and have both of the DLC's downloaded after purchasing the season pass. Do you have to finish the main story before you can start the DLC stories? If not, how do you access them? They are not showing up in My Missions.
Just go to a fast travel station, they are in there.
Fast travel to Oasis for Captain Scarlett and Her Pirate Booty DLC or Badass Crater of Badassittude for Torgues Campaign of Carnage DLC.
