Its an easy job, just nuts and bolts and big pieces. I would suggest a trans jack, for removing and replacing. That freaking T18 weighs a ton. I hoisted one in a jeep by hand when I was younger but wouldn't attempt that now.
When I did mine I replaced pilot bearing and the rear main seal too as long as I was there, got the flywheel resurfaced. Another trick I learned was when going back in get 2 real long bolts for the top 2 holes on the bell housing, cut the heads off the bolts and use them for guide pins when trying to stab the shaft in the pilot. I also had a buddy help me to put it in, it helps to have another set of hands and eyes. Another thing is the silly tranny jack will have a crappy chain to hold the trans in position, ditch it and use a rachet strap or 2. Good Luck
