I have an 05 Tundra Double cab and when i read his post i also laughed about not knowing where to put the oil in...i then went out today to look at my truck and let me tell you something...there is NO dipstick on the 05 Tundra double cab. I looked in the owners manual and it said nothing about the tranny or how to check it. I do know one thing though...the 05 Tundra requires Toyota Genuine ATF Type WS. And if you drain the pan it will require 3qts to fill it back up...where you put that in, who knows?
