I did it on the floor with the X on four jack stands. Not ideal, but it did the trick. Was a little messy but not too bad. I had my friend sitting in the car shifting gears while I pumped. He was also watching the analog values for the tranny in INPA on my laptop and shouting the fluid temp to me as it went up. You have about 5 minutes until it hits 50 degrees Celsius and then you have to close it up. It was enough time, but was a close call. If I didn't have to switch the fluid pump to a new bottle 5 times then it would have gone faster. Line up everything you need right next to you on the ground and you should be fine. I'm changing the filter again because I'm OCD and I got it cheap from ECS tuning, they were having a sale. Unnecessary for sure, but why not.
