just bought a 04 4.0 with 109,000 miles. I already did an oil change, air filter, brakes all around, new wipers and a few things here and there oh and tomorrow i am going to install new sp-500 plugs... i really want to do a tranny filter and fluid change. will it hurt the tranny if i do that? i know how the 5r55w tranny can give problems (i had a 02 and i went to hell with it) so i am trying to just extend the life of the tranny... should i use Lucas or anything? how many bottles do i have to pump into the tranny? 5? i have not done this since 2012 when i had my 02....
