Add pork and soda to the slow cooker. Cover and cook on high for 4 hours.
After 4 hours, combine all remaining ingredients in a large bowl and whisk to mix well.
Add this mixture to your slow cooker and cook for 2–3 hours more, until pork is falling apart as you try to remove it from the slow cooker.
Shred pork pieces with a fork, removing fat as you go, and place back in the sauce. Serve warm.
