Not much fluid in the lines, but I did lose quite a bit when it spewed out. When I tried to fill it when the truck has been sitting for a day, a lot of fluid spilled out of the fill plug. So I didn't fill it, I recon I am missing about 1 quart including all the fluid I lost before replacing the pipes. A master mech told me that I have to loosen the fill plug, start the cold truck, remove the fill plug, pump the missing quart or so back in, and replace the plug. I just haven't had time to do it. I've driven it almost 1k miles like this, but need to do it soon for a peace of mind.
The tech is correct. I don't have the manual handy, but IIRC you are supposed to run the truck until the bottom of the trans pan gets to about 140 degrees and then fill until it is dribbling out of the fill port.
I went out and bought an IR thermometer specifically for this task when I was doing it.
