hey guys i am going wheeling this weekend and i havent changed the fluid in my trans since i got my truck, it was changed when i forst bought it by me but i havent changed it since i should say, when i changed it, the truck had 137k on it, i used a good filter kit and mobil 1 fully synthetic trans fluid, the truck has 191k on it now, so lets say over 50k sincce its last change of trans fluid, it shifts perfect, doesnt slip, works like new. My 2 questions are, how many quarts would i need to buy once i dop the pan and replacce the filter, and how many does the converter hold, I have an AOD tranny btw. Also i have heard that once a trans has so many miles on it, if u chasnge the fluid, it will start to slip and i do not want that happening, the fluid on the stick looks pretty good still, a little dirty, but hey its old so thats fine, just wanted you guys's input since im not sure about how many quarts i need and since the trans works perfectly with no problems or leaks or anything, and even having 191k on it, if changing the fluid is a good idea, thanks guys
