Rebuilding a 4L60E myself, at home.
I'm really not interesting in hearing "that's crazy..." so don't bother 
Has anyone attempted it? My tranny is fine now, and I suspect it will be fine for the time being while I have (hopefully soon) just a hotcam. I want to strenghten the tranny before I spray the car though.
Some terms I've heard thrown around are
"billet servo"
"kevlar bands"
"extra clutch packs"
I'm no tranny expert, but I'm good w/ tools and so is my dad & a few friends. I know I'll need a full 4L60E manual, any suggestions?
I'd love to see pics of a torn apart 4L60E if someone has them... anywho, I'd like to hear from experience, including the tranny builder experts we have around here

DUDE Thats NOT Crazy!
From what i understand you just have to be rather CLEAN (ie NO DIRT) and the order of certain parts is absolutely CRITICAL. for one who takes his time, has the necessary manuals, and some mechanical knowledge can accomplish a transmission rebuild. In fact i plan on doing the same and rebuild my trans myself too.
this is the best i could find for you. Brent hasnt put any directions up but there are pictures.

Good luck and let us know how it goes.

I'm in the midst of a 700r4 rebuild which is basically the same as the 4l60e.
It isn't really THAT hard. What it is, is time consuming and you need to keep track of the parts. Also you will need some specialized tools such as the rear clutch spring compressor and the regular clutch spring compressor that mounts in a vice on the bench. You will also need some other specialized tools for the 4l60e probably the same ones as for the 700r4.
Go to this site and it will give you a rundown of what special tools are available.

Don't get scared though, you don't need all of them! But do expect to pay a good amount of cash on tools in addition to the parts.
And pick up the manuals as well as the video.
This site:
http://www.kdsperformance.com
Has the books and videos. They also sell rebuild kits at a pretty good price.
Don't expect it to get done in a weekend!

I'll just let FLP handle my rebuild. 
However do make a write up with plenty of pics. It will always come in handy...

I am going to go with the 3600 but I just don't know when. As you know times a little tough in buisness right now. $$$$ is a bit harder to make. This grown up, wife, mortgage $h*t is for the birds....
Actually the wife is cool its everything else.... FLP is waiting for me though with a good price...

I did mine, it's not crazy.
I did have to come up with creative way's of pulling and installing parts. For example I made my own spring compressor about $3.00 in parts. Teflon seals were fun to install, I used a aluminium can to install those. I suggest do alot of reading on this from various websites and transmission site. I did almost a month of research on this alone.
First you need a manual.

Here are some other sites.

That's all that I can think of right now.
