I've had the trans out of My 06 GTO 3 times in the last month. I couldn't get mine to bleed like You would with brakes. I had someone hold the pedal down while I broke the bleeder in the bellhousing loose. I left it open about 5-10 seconds then tightened it back up. Mine normaly bleeds in about 5 times. Make sure that You keep fluid in there they don't hold much.
