it's not hard i just hate doing it.... i suppose i contradicted myself a little bit when i said clutches are never really that hard but trannys are always a bitch.... so i can see why you'd be a little confused.... but usually when i think tranny im thinking automatic...and well i've never liked dealing with those much at all, manuals are lighter, smaller much easier to work with....it still only took me about 3 hours to replace the tranny in my civic and it wasn't hard at all.....so a manual being smaller and lighter once you resurface the flywheel put the clutch on the flywheel and put the tranny in....shouldn't really take that long, it's not hard at all.....but i still hate doing it with all that asbestos crap and the fact my old tranny had a huge hole in it so i was covered in atf all while putting the new used one in
