Its not exactly a book on the subject, but the bently manual is pretty detailed on taking it apart and working on it. The VW Beetle Performance Handbook, by Keith Sueme covers trannys enough to give you an idea of what is often done to upgrading it.
10 minuts at a book store will give you enough time to glean Suemes book.
