Well this weekend is time for my transmission service. I bought a Hayden's 679 trans-cooler and looking through some threads about how to mount it. It seems like you would want the cooler after the stock cooler so the coolest fluid goes back in the transmission? Also I am trying to figure out how to do the flush. Can someone help me with this a little bit. I am going to be doing it in my driveway with my pops. About how much fluid do you guys think I will be using? With the new cooler and added lines I will have to add a little bit more fluid, any idea how much? Thanks for the help.
