Читать книгу Chrysler TorqueFlite A-904 and A-727 Transmissions - Tom Hand - Страница 8

INTRODUCTION

The 3-speed TorqueFlite was produced from around 1960 until 2003. The basic design of the transmission covers two families: the smaller, lighter-duty A-904, and the heavier, stronger A-727.

The original goal for this book was to cover just the rebuilding and modification of the TorqueFlite transmission but experience in the engineering field taught me that it’s important to understand what’s inside and how and why things work before trying to repair them. Therefore, I expanded book’s scope. Chapter 1 briefly covers the history and evolution. Chapter 2 details the parts inside and how and why they interact. Chapter 3 covers troubleshooting. Chapter 4 provides step-by-step A-727 disassembly procedures. Chapter 5 addresses subassemblies and their reuse or replacement. Because of its importance, the valve body is covered in Chapter 6. Chapter 7 details the reassembly along with air checking and adjustment. The torque converter is covered in Chapter 8. Chapter 9 is dedicated to parts and processes to add strength and provide shift improvements.

The scope for Chapter 9 was to discuss street and mild strip/semi-heavy-duty applications and not get into “extreme” TorqueFlites. I did this for a good reason: to build SAFE and severe-duty transmissions requires the right combination of parts and technologies. I strongly suggest talking with reputable builders and the ones I listed (along with many others) know what to do to TorqueFlites to prevent catastrophic failure. Please be safe and use their expertise.

Appendix A is a relatively comprehensive list of TorqueFlite transmission numbers from beginning to end. All numbers came from Chrysler sources but while assembling it, I found variations and omissions. (Numbers of remanufactured Torque-Flite were omitted.) I ask that if you have updates, additions, or corrections, please contact me through CarTech so the changes can be made.

Appendix B lists specifications for assembly and adjustment. Troubleshooting charts are provided along with torque converter specifications.

Appendix C has modification suggestions from industry-leading TorqueFlite experts, experienced transmission mechanics, and Mopar enthusiasts. The Source Guide has contact information for companies and several prominent individuals in the world of TorqueFlites. (There are many others in this field and no ill will is intended by their omission.)

In today’s age of rapidly advancing technology, Internet sources are often used exclusively, which may cause books to be overlooked. I hope that after reading this CarTech offering on TorqueFlites, you refer to it often for general and specific information on this amazing transmission.

This 1962 Dodge has a 1965 A-727 case and geartrain, performance-lined rigid kickdown band, 1971 pump and clutch retainers, and a TransGo TF-3 valve body.
