    I would simply park the rig on an incline and loosen a few of the rear bolt on the tranny pan and Drain it out a little. In a catch can of course.

    For every ~5/8" on the dipstick you're about a quart over full in my experience. Get a piece of hose and unhook the line feeding the fluid cooler. Put the hose on the end of that and the other end into something to contain the fluid. Start the truck. Run over and watch to see how much fluid comes out. Be prepared to run back around and shut off the truck.

    It comes out pretty quick, especially if your truck is cold and the fast idle is on.

    The previous owner of my truck noticed that it was leaking ATF. Well, they must've thought it was the transmission even though you could see where it was dripping off the transfer case. The transmission was about two quarts over full and the transfer case was about two and a half quarts low. Rocket scientists, I say.

    Pick up a small hand pump at your local auto parts store. They work great for stuff like that.

    Here is the easiest way to do it. Go down to your local quick lube and ask them to use their evac-tube to suck the tranny fluid to the right level. it is just a long thin piece of flexible tubing you feed down the dipstick. I have done this many times for people at my lube shop. I am sure every lube shop has one and they will know exactly what you need.
