How to Work with and Modify the Turbo Hydra-Matic 400 Transmission

Great reference for rebuilding any TH400 - contains complete information in a step by step format. This is the first reference I've seen that contains information about the TH400 used by AMC (Jeep) other than the actual service manuals.

Lots of good detail and easy to understand information for the experienced mechanic, even if you've never rebuilt an automatic transmission.

Wonderful. I read this book cover to cover. I've never tackled a transmission, and the subject has always intimidated me. I knew the general theory, but after reading this book I feel confident to rebuild my own TH400. At least if I have trouble I'll know where to look and how to communicate the problems to someone else now!

I'm an accomplished mechanic and found the manual to be very comprehensive. I've not yet done the work, but have read the manual and appreciate the author having taken the mystery out of automatic transmissions. He's cost-conscious and he shows how to do the work with common shop tools rather than expensive OEM special tools. He also thoroughly explains the advantages and disadvantages of modification, be it high performance or performance enhancement. I'm anxious to begin!!

This book is marvelous. With absolutely no prior experience with automatic transmissions, I have successfully used this book and Mr. Sessions' previous book on the Turbo Hydra-Matic 350 to rebuild two transmissions. For the novice, all you need is a Master Rebuild Kit and about two weeks of patience, and you can save over $1000 by doing the rebuild yourself. The book has a good discussion on theory, but you can skip right to the "how-to" sections and follow the text/pictures to a successful end.
