I would suggest that you use the Mosaic_anisotropic component. This
component is available in the new version 1.2 of McStas, which I believe
is already installed at the ILL. It is a direct replacement of the old
Monochromator component (same parameters), but it correctly handles many
more non-standard configurations, including a transmission configuration
like yours.

See the manual for further details, or just ask again if you have any
further questions.

Good luck!

 - Kristian.
