It may help if you could post the output of the following: System.out.println(sourceCRS); System.out.println(targetCRS); System.out.println(transform);
More specifically, it would allow us to see if a datum shift is applied using Burwa-Wolf parameters. If the datum shift appears to be applied as expected and in the particular case of NAD27 to NAD83 transform (the later is pratically identical to WGS84) it may be worth to try the following class, which should provides the most accurate transform available in GeoTools for this particular pair of CRS: http://javadoc.geotools.fr/snapshot/org/geotools/referencing/operation/transform/NADCONTransform.html This class was wrote by Rueben Schulz. I don't really have experience with this one, so I may not be able to help with it. But it probably work as expected.
