So I decided that since I've got the next two days off, I'd go ahead and give the tb a transmission flush since it has 170k on it, I bought it 8k miles ago, and I don't know when the transmission was flushed last. I did some research and decided that pulling the return line on the cooler and letting it pump out would be the easiest way to go. I went ahead and ordered me the Hayden adapter and also figured since I'll have the pan down, that I'd go ahead and order me the Dorman pan with the drain plug. Everything started going fine, broke the line loose, pulled it out of the cooler and to my surprise fluid started gushing out like crazy. In all I got about 9 quarts out just letting it drain without starting the truck. After everything was done, I noticed that the trans fluid was a nasty "poo brown" color, and figured that it was time after all to change it. So now I'm sitting here baffled, wondering how I managed to drain 9 quarts just from the cooler alone, until I decided to swirl it around with a screwdriver...
So here I am pulling out the radiator and basically the whole front end to get to it. I figured I'd post some more pictures below of the aftermath.

Hopefully next week I'll be replacing the cooling lines (they're starting to rust and leak) along with installing a cooler and inline filter (gotta love freebies), and I'll be keeping a close watch on the trans... I really hate the thought of coolant running through it though

I poured it into a clear jug I had sitting around to show what I call GM's 2-tone tranny fluid
