Torqueflites For Dummies

So I have my 904 out and wanted to install my TF-1 shift kit while i had it apart to replace leaky seals. HOLY CRAP I wasnt expecting so much disassembly to be involved in just a shift kit install!:oops:
So... What Im thinking is that since I basically have to do a full teardown just to install this kit, I might as well run completely thru this thing since its been at least 20 years since this thing has been gone thru. All i need now is a book to tell me how to do it! Is there a "torqueflite for dummies" type book, and where can I buy it? It looks simple enough, but this will be my first attempt at a trans rebuild. Any advice from the professionals here will be greatly appreciated!
