I want to upgrade the valve body in my tranny, Im pretty sure i have a 4R75w because Ford upgraded the 70w for 2003. But at any rate, i can not find valve body upgrades for the 75w, all the ones i find are for the 70w. any clues what to do?? and getting a 5spd isnt an option...

Your '04 does have the 4R75W:



I am not a slushbox authority be any stretch, however from what I have picked up the 4R75W does not respond to valve body mods as dramatically as the '70--mostly because Ford incorporated much of the popular 4R70 modifications into the '75...
