As for the last bell housing bolt that is in the opposite direction of the others, you need a long extension to reach it. You run the extension through the hole in the tranny-to-engine mount...and you really didn't need to pull the oil pan. You did, however, needed to pull the starter and plastic covers over the "flywheel".
You also need to remove the tranny to engine mount bolts.
Overview: You have to remove the 6 bell housing bolts, 2 tranny to engine mount bolts, tranny mount to chasis bolts (or tranny to mount bolts), torque converter bolts. That should do it....and, of course, remove the CV axles (be careful to not split them apart!).
Are you supporting the engine somehow? Come-along, cherry picker?
