IT1s10 is giving you good advice here,,yes you can get the books at most any library,,,but they won't go into detail very much.
Also you need the correct tool's to do an automatic transmision rebuild.
When i did my first one it was a ford C6, and although it did work,,,it never worked right.
Like ya gotta know how to read a hydraulic circuit diagrahm,,,and have an understanding of hydraulics,,,not just mechanical.
It's like anything else,,,,you gotta do it a couple of time's to be good at it.
And the best tool at your disposal will be a friend who know's what they are doing.
I say ,,,,,Go for it,,,,but pick up a spare Tranny from the Wreckers and swap it out first,,,that way,,,your Fire Chicken will still be driveable.
