fluid type for A-518

i got a transgo kit un-opened still in box for 25 bucks off ebay, and i have a b&m kit but i think it may be a manual valve body kit, not 100 percent sure cause its at my other place in idaho, ill have to check and see when i go up there, i dont want a manual valve body i want it to hold in gear like 412 stroker said. When installing the kit do you have to do a bunch of drilling? i was hoping there was a kit to where you could just pull the old valve body off and bolt the new valve body on and be done with it, i know i could handle that lol but i bet there is more to it then that, i still have not opened the transgo kit i have.
