You won't be sorry, trust me. That book will teach you things 90% of the transmission "rebuilders" don't know.

Please don't take this as a bash against transmission rebuilders, but most rebuilders are really just assemblers. They may know how to properly assemble a transmission, but they really don't know what's going on inside a transmission once it's in the vehicle. This book will teach you the basics.

Once you have the basics down, you'll still need to have the Theory & Principles of Operation (T&PO) for each transmission you're trying to diagnose as they come along, but this book gives you the fundamentals that you'll need to understand them.

It's impossible to memorize the T&PO of every transmission. There's simply too much in power flow, fluid flow, and solenoid firing order, not to mention what kind of solenoid is each solenoid. You look up all that stuff on an "as needed" basis.

It's sort of like learning to read a road map. Once you know how to read the legend, the mileage spreadsheet, and all the icons, you can go anywhere a map will take you. The same holds true of hydraulic flow charts, power flow charts, and electrical circuits that are shown in each transmission's T&PO books.

You'll get a big kick out of seeing how a torque converter can double the engine's torque applied to the input shaft of the transmission. That's truly wicked, but it works!

Enjoy your book!
