I find it easier to remove the torque converter bolts. Even with the engine out of the car. So much easier to reinstall everything. The idea is to have the torque converter in the transmission at removal & reinstall. Free the torque converter by removing the bolts and then try to get it freed from the flex plate with a screwdriver or such. If it tries to come off at an angle, its likely to get stuck in the flex plate on the nub that centers it. As sixto says, the cooler lines & dipstick, and Bowden cable should be disconnected too.
