I have trimmed it like this:

\version "2.14.2"
\score
        {
        \new PianoStaff
        <<
                \new Staff = "up"{
                \clef treble
                \new Voice = "upper"
                \autochange {
                \relative c'' %If this becomes c' or lower, everything ok.
                              %as it is, it puts everything in the voice of 
"down".
                        {
                        \stemUp{        
                        \bar "|:" bes4 c bes' c \bar ":|" d1 \bar "|."
                        }}}}
                                
                \new Staff = "down"{
                \clef bass
                \new Voice = "lower"
                \autochange {
                \relative c' %this is of no consequence, really
                        {
                        \stemDown{      
                         bes4 c bes' c | d1 
                        }}}}
        >>
        }       

I have put new voices, but it still doesn't work. How would this work? I am a 
relative newbie, so please excuse the clumsiness...
