Tom Hand has been working on and writing about the TorqueFlite automatic transmission for years, so he was a natural for CarTech when they sought an author for a rebuilding guide.

CarTech got more than they bargained for, though. The new Chrysler TorqueFlite A-904 and A-727 Transmissions book sets standards for photography, diagrams, and writing alike.

The book starts with the history of the TorqueFlite, noting its three esteemed inventors, goes on to estimate production over its 43 year run, and then gets into describing how it works, how to do basic maintenance, and what tends to go wrong before diving into rebuilding. Tom Hand covers how previous rebuilders can cause problems, along the way; and has a full chapter on performance modifications (including photos of and evaluations of numerous kits).

The diagrams have all been created for the book — there’s no borrowing from the factory service manuals — and the photography, by Tom Hand himself, is excellent, with fine clarity and careful posing to show exactly what you need to do.

With a list price of under $35, this book is an invaluable resource for anyone who owns a TorqueFlite-equipped Mopar — and that’s most of the surviving classic and muscle cars, with every engine from slant six to 426 Hemi. For a limited time, you can even get one straight from Tom Hand himself .
