Did the flush last night and all went well.
Once I was under the truck, seeing which line to connect the hose to was obvious. I used a 1/2" ID hose with a hose clamp which worked fine. Just to make sure I got all of the old fluid out, I repeated the step where you add 6 qts and then pump it out (so I pumped fluid out 3 times instead of 2).
The only messy part was dropping the pan and replacing the filter.
I have a Chilton (i.e. cheapo...to change the fluid, it says to just drain the pan and then refill with 1/3 of what the capacity of the truck is
) book that says after you add the fluid and start the engine to not run the truck through all the gears. Since the instructions posted here say to run through all the gears as the fluid is being pumped, I hope that's ok. If anyone has any knowledge about this being good or bad, I'd be interested.
Thanks to all who answered my questions. Next time I can just get right to it.
