I have an 89 accord with 5spd trans..im trying to change the fluid in the trans but cant find the filler plug. Chilton book is say that i fill it from the top with a long neck funel. but i dont see a spot for it from the top of the car. does anyone know where i fill it at. and it says that i put engine oil in it not gear oil...any advice would really help me out..thanks.
