As trannies go, it's a fairly light one. Five years ago a buddy of mine helped me replace my clutch and it took us about 6 hours in my garage. At that time, neither one of us had a whole lot of experience wrenching on cars (although I had many years of experience wrenching on aircraft). Having someone give you a hand can speed it up quite a bit. We left the transfer case attached and dropped the whole assembly. Best if you have a place to work on it and your standard tool set (nothing fancy). If you haven't got the new clutch kit yet, get one with an alignment tool...that'll save some time.
