The coolant passes from one side to the other, through the adapter plate. The oil filter adapter/cooler and starter also attach to it... So, other than dealing with those systems, it's just a matter of bolts... You'd have to remove the transmission and flex-plate to get to all of the bolts behind the flexplate.
