It took me about half an hour to drop the C6 out of my motorhome with a regular floor jack.
I had it backed up on big ramps, I rolled my jack under it, with a block of 6x6 on it, and a sheet of plywood screwed on it, and the 6x6 was held to the jack was wire mesh, unbolted the tranny and TC, lowered on jack as low as it goes, then I couldn't roll it from underneath the camper, so I put an old pillow on the ground, and dropped the tranny on that, and slided it from the side by hand.
Easier said than done, but yea, half hour to drop it, and about 45min to put it back in when rebuilt.
But the C6 only weighs half of the E40D.....
Engine didn't even need support after removing the tranny! I did put a piece of 2x4 from the ground, to the back of the block to be sure though.
