pTransformArg is null. As a side note, even when opening the file in FWTools 2.3.0, the projection reported is just -> Local_CS[""]

It seems to me that the problem isn't specifically with the coordinate reprojection, but with how the output file is created - a matter you haven't described. What is the output format? How are you setting the coordinate system on the output file? Possibly you will need to provide more context. I will say I don't see any inherent problem with the output coordinate system definition you are using.
