It seems like the only thing i have yet to do to this truck is check change the trany oil. I know there is a drain plug on the bottom but im concerned that there will be an air lock and the fluid will not drain. is there something on top that you can open to get the get rid of the vacume. also is there a place on top to put the new 600 weight oil in there or do i pump it back up though the drain hole like on a lowere unit of a boat.
