Yes. I would not try the job without the engine hoist. You can perhaps block the front of the engine up once the transmission is off, but the process requires that the front of the engine be lifted, in my experience. Because of the placement of the engine mounts the balance is way forward without the weight of the transmission. The engine will tip forward, raising the angle of the rear. It's hard enough benchpressing the transmission back on when the engine is pointed down at the rear. With the angle wrong, you just won't get it on. Then there is the question of the transmission bolts. There are a couple across the top of the transmission which are a bit tight on clearance. Lifting the front a bit helps here too. Mind you, don't lift it too much because you're probably stressing the engine mounts in the process.

I wouldn't try to pull the transmission without a jack. That thing is heavy.
