well first at all I want to thanks the fast replying on my last topic, thanks really. Now I decided to change the transmission fluid by myself, don't trust either my mechanical and don't have the time for the dealer to do the work (here it takes all day long). I've been doing some research about the 6-speeds f21 transmission and have some doubts but its seem easy and I like this kind of work, the manual book says it take 7.4 quarts. My car is a fusion 2008 sel 3.0 fwd 6-speed, I read that there should be a drain plug, but, it only drains aprox. 3qt... so where's the other 4.2 qt? and how can I drain it? A friend gave me 8qt of Motorcraft Premium Automatic Transmission Fluid.
