i have pulled my tranny 4 times in 2 yrs, my advise is:
4 hands are better than 2, really.
buy/make a pilot tool
buy some 4 to 5 in studs to go in the top 2 holes when putting back together as guides
mark your drive shafts
rent a tranny jack (my brother and i lifted one by hand but it wasnt much fun)
other wise, i agree its not to hard, i put in a new tranny last week by myself, took about 4 hrs (aprox) :-/
good luck
