Best place for 4r55e rebuild kit/parts?

[sideman8]

Where is the best place to get a rebuild kit for a 4r55e, and parts like a output shaft?
Also doing a rebuild for the first time is there any special tools i am going to need?

There are a number of sticky posts in the Transmissions forum that saved me a fertilizer load of trouble about two years ago. The diaries cover the sourcing of parts and tools you'll need. Rumor was that I was crazy to do it myself but I rebuilt a valve body and swapped out a tranny and later the transfer case with the help of a lot of people who hang out here.
