Can a newbie restore a 727 or 904 transmission ?

I did my first 904 when I was 19 and I'm not God's gift to automatics. What I did was follow the FSM. When it said remove the pan bolts, I removed them and put them in an envelope labelled "Pan Bolts". When it came to go back together, everything was in envelopes and named what the FMS called them. Worked great.
