Automatic Transmission Removal

Has anyone here attempted or performed the automatic transmission removal? I'm in the final stages of prepping the engine for drop, but the guide (I believe by Bentley) is very obscure and hard to understand. Does anyone have any advice or step by steps? I have been searching, but it appears there isn't much. I'd also appreciate any explanations of the "special" tools that are required. I plan on keeping the transmission mated to the engine when the drop is performed, then I can take it off after it's out.

We do this all the time, so here goes:  Tools 1 & 2 are an engine support bar (you must support the engine while removing the transmission from the car and leaving the engine in).  Tools 3 & 4 are used for the torque converter unbolting process and then retaining it with the transmission while removing the trans (you really do not want to drop a converter, it gets very expensive very quickly).  Tool 5 are hose clamps for the transmission cooler lines that have engine coolant running thru them.

I did this at home with no special tools per se.  I did use a generic engine support bar, I think it was a harbor freight $50 item.  Use some foam pads or at least a few towels underneath the bar where it rests on the car so it doesn't scratch/dent it...the stands that came with it didn't fit the Porsche.  I also supported the engine underneath with a jack and jack stands.  I just drained my coolant and filled it with new stuff on the way back in, so didn't have a need for the clamps, but those are pretty easy to find anywhere. I just used screwdrivers for the dowel pins to hold the position, but definitely have to be careful not to let the TC drop.  I used what you attached as well as this guide:  http://www.pelicanparts.com/techarticles/Boxster_Tech/37-TRANS-Drop/37-TRANS-Drop.htmeven though it is for a manual, it has some good step by step information.
