I had good luck bleeding it on the bench. I watched a video on youtube that gave me the idea. The slave and MC both unbolt from the truck, so you can take it to you bench. It made it much easier.

take the slave loose from the trans, and slowly push it in and out with the line up, for awhile. it will bleed it all out.

with line facing up you mean and with the bleeder unscrewed or not thanks for the reply

Find someone hooked on methamphetamine and have them pump it up.

It takes about 3500 pumps of the peddle so I use both legs and both arms to do it.

leave the bleeder tight. use the slave, to pump the fluid back and forth, it will air itself out that way pretty quick. took like 2 min on my cummins swap.
