Can a newbie restore a 727 or 904 transmission ?

I've done both a 904 and 727, and I'm a newbie. It's not very hard, but you do need to pay attention to detail and be very clean. TAKE YOUR TIME and do not rush, and if the beers start going down easy, take the rest of the day off because you WILL miss a step/forget to install something/install something backwards. If something doesn't seem to be going together as easily as you think it should, STOP. Pull it apart and find out why. Don't force anything together. Double and triple check your work. Did I mention take your time?

I have Tom Hand's book, and it's great.
