The factory way to do it involve supporting the engine, dropping the subframe on the trans side, going in with a special fixture on the trans jack and pulling the trans out.

Most guys I know support the engine, drop the entire subframe completely out of the way, use the trans jack adapter or not, if they run without they will typically use a big piece of squishy foam between the jack and the trans and then use one of those ratcheting nylon straps to secure the trans to the jack. This is the method I use and it works very well but unless you have an engine support fixture you are s.o.l. I have seen other guys on the various boards that have advocated pulling the engine complete to change it out. To me this seems extreme but then again I am a proffesional with and entire shop at his disposal. I have seen some crafty ways to support the engine on line as well. The problem with pulling just the trans I would think would be getting the car far enough into the air that you could pull it out. It is a frigging nightmare anyway you look at it. Let us know how it turns out or where to send the flowers after you drop the motor on your head, just kidding (I hope).
