This is an excellent book and how to make one of the best automatic transmissions ever made, even better. However I recomend doing at least one standard torqueflite rebuild before venturing into some of the modifactions that are shown in the book. The torqueflite is one of the easist automatics to overhaul and a very durable transmission. Information is this book is meant for people with some experience with this transmission.This book is a huge asset to those who work on these and rebuild them. Years worth of technical information is compiled and shared in this book. Good torquflite mechanics may be pretty easy to find, but finding one with that has all the knowledge in this book are not.
