Ok, removing the transmission with the converter still attached to the flexplate is physically possible, but the worst idea you could have in this process. Bad, bad, bad. DO NOT do that. Absolutely 100% positively remove them together. Period and end of story on that.
First disconnect the battery and pull the transmission dipstick.
Then remove the inspection plate at the bottom front of the transmission that is held on by 2 bolts and the little rubber plug on the transmission bellhousing. Look on the drivers side of the block, about where the starter would go if it weren't on the other side of the engine, and remove that plug as well. You can easily reach the converter nuts through that hole by putting an 18mm socket on the bolt on the crank nose and turning clockwise ONLY to get to each of the nuts. There are 4 nuts. Done here.
Remove the 3 starter bolts pull it out a little and prop it. The top bolt will give you fits. Done here.
Drain the pan at some point before the next step.
Drop any exhaust that interferes (make sure to unhook the o2 sensors before you stretch the wires past their shorter than should be limits) and remove the driveshaft.
Support the transmission and remove the crossmember.
Disconnect all electricals and linkage from the transmission.
Lower the tail of the transmission and remove 7 13mm head bolts.
Wiggle the transmission loose and remove it.
That's most of it off the top of my head and I am sure I forgot several things. Probably something obvious even, but I am sitting at home on the couch watching tv with my wife, so...
