Just wanted to know if anybody off the top of there head knows how much tranny fuild i would need if i just dropped the pan and changed the filter. Just wanted to know, car has 150,000 on it and i do not know if it has ever been changed. thanks guys:)

8-9 quarts seems to be the norm. good way to make sure is to catch/save what you drain out...then you use this amount as reference when you are topping off (put in what you took out)
