I did mine a couple years ago in the garage with no lift.

Some tips:

- Get some help. It's definitely a two person job getting the trans bolted back up to the engine.

- Get a nice trans jack. That Amazon one probably isn't going to cut it...the trans is a beast. I ended up renting one from my local rental place.

- Separate the t-case from the trans. It's only six nuts and will make your life MUCH easier.

- Replace the rear seal while you are in there. I didn't and it started leaking shortly after.
