If you're trying string replacement in bash:

bash$ cd /usr/lib
bash$ pwd
/usr/lib
bash$!?cd?:s/usr/var/
bash$ pwd
/var/lib

I don't know of a 'cd' specific one to do that, but it's simple to
write a bash function:

function cd () {
  if [ -n "$2" ] ; then
    nd=`pwd | sed 's/'$1'/'$2'/'`
    builtin  cd $nd
  else
    builtin cd $1
  fi
}

bash$ cd /usr/lib/
bash$ pwd
/usr/lib
bash$ cd usr var
bash$ pwd
/var/lib
