I hope you have read 
http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Transpose#Transpose
and
http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Instrument-transpositions#Instrument-transpositions
which explain how to handle all these issues without rewriting the 
source file to concert pitch. Note also that the hint provided in a 
previous answer, of using \displayLilyMusic will result in absolute
pitches, not \relative.
