Noob question on separating block / tranny

I really don't like posting such basic questions, learning as I go here :newb: and still showing my ignorance...

I have an engine and tranny on the garage floor, still bolted together, pulled em out of a 1990 truck to eventually use in my Dart.

Question is, on the flex plate, can I just take the 4 bolts out one at a time, and then unbolt the bell housing from the block? Then the tranny should just slide off the engine (?)

Tricks? Tips?

BTW, I just ordered a shop manual for my car, it's not here yet, so be nice 8)
