In the past I have used a floor jack to set it down on stacks of 2x and 4x wood under the front and rear of the transmission. Then I slid the jack out and removed the wood at each end one piece at a time until it was on the ground and pulled it out. Installation was the same procedure in reverse.

As long as you have enough ground clearance between the top of the bell housing when it's on the ground and the rocker panel your good.
