@Michael Gain anything special need to be done when dropping the pan? You have (had) the 8hp70 right? I've got the new pan, fluid, and a small ratchet with T40 bit; just haven't found any info on special technique to getting the pan down.
You've got mostly everything you need. You will need a small socket (I think 7 or 7.5mm) to remove the heat shield bracket. I ended up using an adjustable wrench as well. One of the driver side bolts is pretty close to the frame and the ratchet will only get a turn or two before stopping.
As far as getting it down, apply even, downward pressure until the filter disengages from the mech sleeve. Once free, move the half full pan towards the front of the truck (over the cross member), rotate 90 degrees, and slowly lower the pan between the cross member and catalytic converter to fully remove
Hope that helps!
