i drained my tansission fluid yesterday without realizing there was no dipstick to refill it. to refill into the fill plug what eactly do you have to use and how. right now i have a pump that connects to the transmission fluid bottle, but the end that the fluid comes out has a plastic thing that is to big to fit up into the fill hole. i tried to pump some into the bottom of the hole but it just drained back out. please help
