Weight, cumbersome and rather clumsy or at least I'll say it can be. Personally I like to remove the engine and transmission together and separate them once they're out. I'm less likely to drop something that way. Although in my youth I'd just lift it out, set it on my chest and then move it over beside me. I see you're in Dallas, so unless you have an airconditioned garage you're going to have sweaty hands now and that's not always a good combination with a greasy transmission. It pulls straight out. Take off the 4 bolts (any order). There will be a round lip (formed by the front retainer piece) which fits into the hole in the bell housing, and this holds it in place until you pull back and separate it. Good luck.
