Author Tom Hand shares his decades of experience rebuilding TorqueFlite transmissions with chapters dedicated to troubleshooting, disassembly and reassembly, performance modifications, post-installation procedures, and the most thorough source guide offered in print, ever.
The A-904 and A-727, debuting in 1960 and 1962, respectively, are 3-speed automatic Chrysler TorqueFlite transmissions. In Mopar circles, they have become synonymous with strength, durability, and performance. In fact, 43 years after its first application, A-904s were still found in the Jeep lineup! While TorqueFlites are known for their dependability, many have endured a tremendous amount of abuse over 50-plus years when hooked up to V-8 Mopar powerplants. There is little doubt that some of these automatics could be prone to failure, or at least need a thorough rebuild.
This book will keep money in your pocket and add experience to your résumé, but more importantly, it will help you get your Mopar back on the road!"
