What i did was lift the car up and set it on jackstands. Then i set the trans on 3 pieces of cardboard about as wide and long as the trans. I then proceded to push the trans under the car and into place. By using more than one piece of cardboard, the trans will end up with one sheet under it and a trail of sheets from where you pushed it from. Then you can use a pry bar between the ground and the pan to lift it up enough to shimmy a piece of wood on each side until it's up high enough to slide your jack under. Or if the engine is out, just lift with your knees and have someone slide the jack under. I've done at least half a dozen like this in the driveway. Just have to stick the dipstick tube back in after you slide it under. Use stock pan for sliding trans around, chrome one after its installed, or if using stock pan and its super clean, then tape up a sheet of cardboard to it so its not scratched.
