Chrysler TorqueFlite A-904 & A-727 Transmissions: How To Rebuild is bound to become an invaluable resource for every owner, mechanic and restorer of these classic three-speed auto trans. It is the universe for TorqueFlite transmission rebuild instructions: components and operation, detailed assembly, troubleshooting and diagnosis, and performance modification, Within these 200+ pages and over 600 color photos and charts, expect the 411 on not just how to manage these tools but the history and application of their decades long use. This tome is far more than a how-to. It's a great read for anyone that wants to understand how these puppies work!
Chrysler introduced these trannys in the early 1960s. They quickly became popular in the Mopar community and the rep of the A-727 and A-904 quickly spread. Performance, durability, strength. Even after five decades, they are considered monsters that may be slowed down but can't be stopped. These TorqueFlite transmission rebuild instructions will ensure that never happens. The author - an experienced hand with these transmissions - provides detailed and easy-to-follow guidelines, protocols and procedures for upgrading everything from planetary gear to levers and struts. There are extensive appendices for finding numbers, performance modifications and a batch of troubleshooting charts and specifications.
