The best way and easiest way to bleed this clutch is to have everything installed and remove the reservoir cap and pull a vacuum on the system with a handheld pump. Cycle the pedal a few times and the air will be gone. If you bleed all the air from the slave cylinder with the transmission off then you will reintroduce air into the system when connecting or disconnecting the push connect fittings. You need resistance in front of the slave to bleed it. It can be done with the slave cylinder in your hand and off the trans but is is best to do it in the truck installed. You can do the vacuum method or the actual bleeding procedure if you would like that I can post it.
