I use dude, bro, man, guy, bud etc, etc, etc with everyone, regardless of gender. If I knew I was speaking to a trans woman, I'd hold off, though, out of fear of triggering her dysphoria. Of course, if someone (cis or trans) asked me to stop I would without hesitation, but unless I had some inkling that it would be specifically upsetting to any given woman, it would be a large, default part of my vocabulary.
