4 or a 6 cyl? I swapped the one in my 2.7L a few years back, I've linked some of the tools I used.
http://www.harborfreight.com/3-8-eighth-inch-heavy-duty-flexible-ratchet-96369.html this was great for the hard to reach bolts where you couldn't get a straight handle ratchet on it. A crowsfoot was helpful for getting the driveline bolts undone. The bolts that held on the flywheel were a little strange I used some spline sockets
http://www.harborfreight.com/7-piece-3-8-eighth-inch-metric-spline-socket-set-96362.html to get them off. I got my flywheel resurfaced at Six states in Salt lake. I also used a transmission jack
http://www.harborfreight.com/450-lb-capacity-transmission-jack-39178.html to get it in position. I ended up needing some extra hands getting it lined back up because it shifted when I pulled it out.
I've got a jack if you need one, overall it wasn't too bad, I spent way too much time on the drive line bolts than I should have, they had never been removed and a normal wrench didn't have the leverage I needed.
From memory here's how I remember doing it
remove drive lines from transfer case
remove shift levers
remove cross member (support transmission/transfer case with jack)
unbolt starter (pull ground from battery first) I tied it out of the way but did not remove.
unbolt clutch slave cylinder again tied out of the way.
remove bolts attaching bell housing to engine
slide out/drop transmission/transfer case unit
remove pressure plate/clutch
unbolt flywheel
remove pilot bearing (I made something to pull mine, I'm sure there is an easier way to do it)
reverse procedure to reassemble, make sure you use a clutch alignment tool so everything goes together and is lined up.
