Do I need a visa to transit Montenegro ?

You didn't say clearly what kind of visa you have? If you have multiple Schengen visa, then there's no problem entering and leaving these countries! If you have a blank passport, there's a big problem.
With valid US and Schengen visas, you can also enter Montenegro! If you don't have them, you can get an invitation letter.
If you have Schengen visa or US visa multiple times, you can get UK visa exemption. For a totally blank passport, you need to apply for invitation letter through travel agencies.
