Hehe, trick question, right?
Seriously, if you have all the tools you need, have some guidance from this forum and a good place to work you should be able to have that auto out on the floor in 90 minutes. Stabbing it back in there may take a little longer because it's fiddely to get that sort of stuff back together sometimes.
You definitely need a purpose-built transmission jack with a flat surface (goes under the pan) and some chain and long bolts to secure the tranny to the jack. I rent it when I need one.
The other trick is that the bolts at the top of the bellhousing are accessed from behind the engine and below the vehicle. There is simply not enough room between the firewall and the back of the engine to accomodate a ratchet.
To get to them, remove the rear motor mount and allow the back of the engine/tranny to drop down. Have a couple of long (24") enxtensions and wobble joint ready. You can get under the car and snake the extensions up across the top of the tranny and access the 2-3 really hard to reach bolts. With long enough enxtensions, your ratchet will be back by the tailpiece.
One more thing...
I just remembered that the tranny oil cooler fittings were a different diameter between the original transmission and the one that we replaced. I think TO cut the flexible part of the lines and spliced it to make the transition.
