Well, My 2 cents is that most of the dealer service intervals are a waste of money. You can do most of it yourself (if not all if you are competent mechanically) and even if you don't want to touch your car it should only cost 125-200 bucks at a regular shop for the same thing. 90% of the cars that come in to my shop for service intervals have the original checklists with them of what is supposed to be done, and they are mostly handled by the lube/light mechanical guys. It really is a glorified oil change, with a bunch of checks that most decent shops will do for free (the checks). This is mostly because if any of the checked items need fixing, that shop makes money fixing them after. As far as the tranny flush, we do charge $75 for that, and it is worth doing - but I included that in the 125-200 range figure.
