GM 4L60 4L60E TRANSMISSION FULL WORKSHOP REBUILD OVERHAUL REPAIR & PARTS MANUAL

GM 4L60E/4L60 (700R4) Rebuild Procedures. The General Motors 4L60 (also known as the THM700R4) has been with us now for over two decades and, along with the completely computer controlled 4L60E version, has quickly become one of the most widely used late-model GM rear wheel drive transmissions found in cars and lighter-duty pickup trucks. This unit’s time-tested durability and wide gear ratio spread of from 3.06:1 to 0.70:1 make it the perfect unit for a really wide range of different applications. Although many of the head or lead rebuilders in today’s transmission shops ‘cut their teeth’ on this unit, many rebuild technicians join our industry each year, and usually need to find their way through this unit pretty quickly since it’s definitely one of the ‘bread-and-butter’ transmissions, one that brings a lot of work into your shop. There may be parts of the rebuild process that you are not very familiar with, or you may be new to this particular type of transmission. In either case, you need some point of reference- something that will show you how to proceed when you are not sure (or have no idea whatsoever), and that is exactly what this book is designed to do.

You will not find a photocopied section out of a factory manual between these covers. In fact, you will notice a substantial difference between the book you are holding and any other books written on the subject. This is because, as this book was being written, the author was rebuilding a 4L60E step by step as he was writing this book. This helped assure that there would be no missing steps (and it was also real handy for taking pictures along the way…). This book was written for transmission rebuilders by a transmission rebuilder, in plain English rather than complex ‘factoreze’ terminology. Although a 4L60E was used throughout most of these pages, the areas where the 4L60 procedures substantially differ from the 4L60E procedures or assemblies will have a separate 4L60 section.

So, whether you’ve already done a few of the 4L60E units, or are about to tackle your first one, this book will show you how to get through the sticky parts of a rebuild, as well as the most thorough way to get through the job, start to finish.
