The statement "Never pressure flush the CD4E..." worries me a bit. Should it?

I have never pressure flushed any drivetrain components. I have also ever heard of anyone else doing it, so I wouldn't recommend it. Most axles, transmissions, engines, and any other lubes I worked at for BMW were drain and fill. The also never pressure flush the coolant, or power steering.
