If it is like a 240, it is not too hard and well worth learning. The only tricky part is those "impossible to reach" top 19 mm bolts in the bell housing. You need 2 to 3 feet of extensions and try a couple of approaches to the bolts. It gets quite easy with practice. The other thing is twisting and turning the tranny to get the clutch cable tunnel to clear on the way out and back in. And you want to have the rear main seal, pilot bearing and clutch kit ready to go while you are in there. Lifting it back in will require a couple of helpers. On the way out, I use Steve S's method of pulling it onto my chest and knees (75-100 lbs, not bad) and sliding out from under it. On the way in, use a jack or two to help.
