try this:
OSG::TransformPtr cTransform = OSG::TransformPtr::dcast(parent->getCore());
if(cTransform != OSG::NullFC)
{
OSG::Matrix m = cTransform->getMatrix();
m.setTranslate(10, 0, 0);
cTransform->setMatrix(m);
}

if the above works, there is a fault somewhere in the type info,
otherwise you probably don't have the right node.
Hope it helps,
