from plone.app.workflow:

   # Trigger any automatic transitions, or else just make sure the role mappings are right
   auto_transition = new_wf._findAutomaticTransition(obj, new_wf._getWorkflowStateOf(obj))
   if auto_transition is not None:
       new_wf._changeStateOf(obj, auto_transition)

new_wf is the workflow used for this object. You can grab that from the workflow
chain configured for the object. You should probably make sure to do this for
every workflow in the chain to make support you handle objects with multiple
workflows correctly.
