GM Automatic OD Transmission Builder's and Swapper's Guide

If the confusing and puzzling mix of gears, seals, bearings and miscellaneous parts make your head spin, this manual by expert mechanic and drag racer Cliff Ruggles offers some clarity to the popular General Motors 700-R4 and 4L60 automatic transmissions.

There's no question that the automatic transmission is one of the miracles of modern engineering, but its many benefits are also accompanied by potential for trouble.

Once your transmission goes, you're not going anywhere. And if the tranny is not working properly, it is wasting performance potential.

Written with the enthusiast in mind, this book explains the history of these transmissions, gives the reader critical identification guidelines, and covers the complete teardown, repair, upgrade and assembly process.

You will learn how to test your GM 700-R4, 4L60, 4L60E transmission to ensure proper operation before you install it back in the car.

Book Excerpt: GM Automatic Overdrive Transmission Builder's and Swapper's Guide: 700-R4, 4L60, 4L60E REBUILDING

Rebuilding automatic transmissions has always been an area of the automotive hobby that has typically been left to professionals and a rare few hobbyists. I have known some extremely talented mechanics, and most still stay far away from any automatic transmission work. I've never fully understood why. Maybe it's the complexity of the valve body, or host of internal components, sprags, planetary gears, clutch packs, etc. At a glance it all certainly seems complicated. In reality, these transmissions can be correctly overhauled, and even upgraded, with a minimal amount of special tools and procedures. Let's proceed and find out how simple these units can really be. A few special tools will be required here and there, but as outlined in Chapter 2, most can be found, purchased, or fabricated with a minimal amount of time and expense. The procedures described in this chapter apply to all years and models of the 700-R4, 4L60, and 4L60E units. Regardless of the year and model being worked on, the biggest difference between them will be in the valve-body area. The internal components remained basically the same through all years of production. Some minor improvements and upgrading occured, but the basic relationship and arrangement of the internals remained the same, even for electronically controlled units. One must keep in mind that when working with any year or model of the 700 transmission, you can remove all of the internal components down to the low/reverse apply piston without disturbing the valve body. The valve body can be left in place, and then carefully removed after removing the internals from the unit. You must pay very close attention to the valve body and the fasteners that attach it to the case, especially for the electronically controlled units, as several different length fasteners were used.
