I have had to remove the trans. and bellhousing on my car quite a few times.
What I have are a set of 4 jack stands mounted on top of a square pc. of 2x10. I used perforated straping material to hold them down. The 2x10's have 4 casters directly underneath them where the legs of the jack stands are.
This holds the car high enough to work comfortably under it. Then I bought a transmission jack from Harborfreight.

This should work for you, and you'll always have the jack stands for future use.
Good Luck
