06 Silverado tranny lines stuck. HELP

I have an 06 Silverado that I blew an upper transmission line on. I have it disconnected from the radiator, and I have the clip off of the connection on the transmission, but I can't for the life of me get the line to come out. I've tried penetrating oil, pliers, a pry bar. I'm working off the ground on a couple jack stands, so I don't have a lot of room to work with.
