The 4T60-E (and similar 4T65-E) is a series of automatic transmissions from General Motors. Designed for transverse engine configurations, the series includes 4 forward gears. The 4Txx family is an evolution of the original Turbo-Hydramatic 125 transverse automatic introduced in the late 1970s.

The '-E' transmission is electronically controlled and features an automatic overdrivetransaxle with an electronically controlled torque converter clutch.

4T60-E[edit]

In 1991 GM introduced the 4T60-E which was a 4T60 with electronic controls. By the mid-1990s, the 4T60-E was the transmission of choice in nearly every front-wheel drive GM vehicle with the exception of compacts. A heavy-duty 4T60-E HD was produced only in 1996 for the superchargedGM 3800 engine. The 4T60-E was phased out in favor of the 4T65 beginning in 1997.

The 4T60-E featured a 245mm torque converter with varying stall speed and gear ratios. For example, a '95 Beretta features a 1650 rpm stall converter as opposed to '99 Century converter with a stall of 2095 rpm. In the 4T60 family of transmissions, the combination of drive-chain sprocket ratios and the differential gear ratio together offer up to 12 different possible final drive ratios to allow the transmission family to cover various engine and vehicle applications.

Replacing a complete transaxle should only be done if a unit is verified to be the same as the unit it replaces, as in addition to the up to 12 variants of the final drive ratio, different applications and years can and will have incompatible electrical connectors. The use of an incorrect transaxle will result in undesired operation, up to and including total non-functioning of the transaxle.

4T65-E[edit]

The 4T65-E was introduced to replace the 4T60-E in 1997. The 4T65-E included a larger 258 mm torque converter for some models and many other changes to improve reliability. It is able to handle vehicles up to 6500 lb (2948 kg) GVWR with up to 280 ft·lbf (380 N·m) of torque. A number of final drive ratios are available, with many distinct models. Starting in mid year 2000 models, all 4T65-E models received an upgraded valve body. Starting in 2003 the internal electronics were changed, hardened 4th gear shaft, ratcheting sprags for input and third gear were added. The last application was the 2011 Chevrolet Impala as GM has transitioned to the 6T70 family transmissions for 2012.[1]

  • M15 — 245 mm (9.6 in) torque converter
  • MN3 — 258 mm (10.2 in) torque converter

The Hydra-matic 4T65-E Technician’s Guide is intended for automotive technicians that are familiar with the operation of an automatic transaxle or transmission. Technicians or other persons not having automatic transaxle or transmission know-how may find this publication somewhat technically complex if additional instruction is not provided. Since the intent of this book is to explain the fundamental mechanical, hydraulic and electrical operating principles, technical terms used herein are specific to the transmission industry. However, words commonly associated with the specific transaxle or transmission function have been defined in a Glossary rather than within the text of this book.

The Hydra-matic 4T65-E Technician’s Guide is also intended to assist technicians during the service, diagnosis and repair of this transaxle. However, this book is not intended to be a substitute for other General Motors service publications that are normally used on the job. Since there is a wide range of repair procedures and technical specifications specific to certain vehicles and transaxle models, the proper service publication must be referred to when servicing the Hydra-matic 4T65-E transaxle.

INTRODUCTION

The Hydra-matic 4T65-E Technician’s Guide is another Powertrain publication from the Technician’s Guide series of books. The purpose of this publication, as is the case with other Technician’s Guides, is to provide complete information on the theoretical operating characteristics of this transaxle. Operational theories of the mechanical, hydraulic and electrical components are presented in a sequential and functional order to better explain their operation as part of the system.

In the first section of this book entitled “Principles of Operation”, exacting explanations of the major components and their functions are presented. In every situation possible, text describes component operation during the apply and release cycle as well as situations where it has no effect at all. The descriptive text is then supported by numerous graphic illustrations to further emphasize the operational theories presented.

Problems

The second major section entitled “Power Flow”, blends the information presented in the “Principles of Operation” section into the complete transaxle assembly. The transfer of torque from the engine through the transaxle is graphically displayed on a full page while a narrative description is provided on a facing half page. The opposite side of the half page contains the narrative description of the hydraulic fluid as it applies components or shifts valves in the system. Facing this partial page is a hydraulic schematic that shows the position of valves, checkballs. etc., as they function in a specific gear range.

The third major section of this book displays the “Complete Hydraulic Circuit” for specific gear ranges. Fold-out pages containing fluid flow schematics and two dimensional illustrations of major components graphically display hydraulic circuits. This information is extremely useful when tracing fluid circuits for learning or diagnosis purposes.

The “Appendix” section of this book provides additional transaxle information regarding lubrication circuits, seal locations, illustrated parts lists and more. Although this information is available in current model year Service Manuals, its inclusion provides for a quick reference guide that is useful to the technician.

Production of the Hydra-matic 4T65-E Technician’s Guide was made possible through the combined efforts of many staff areas within the General Motors Powertrain Division. As a result, the Hydra-matic 4T65-E Technician’s Guide was written to provide the user with the most current, concise and usable information available regarding this product.
