ATSG General Motors THM 4L60-E, 4L65-E, 4L70-E Transmission Update Manual Book

Description

The ATSG GM THM 4L60-E / 4L65E / 4L70E Transmission Update Handbook
Covers engineering changes that have occurred from 1993 to 2009, parts affected by the change, interchangeability, and part numbers! A must for 4L60-E rebuilders!
Since the introduction of the
THM 4L60E
transmission in model year 1993, there have been many major engineering design changes to improve durability and reliability.  These changes have affected nearly every part used in the THM
4L60E
.  This "Update Handbook" will explain each change, the parts affected by the change, and any parts interchangeability concerns created by the change.
Beginning at the start of production for model year 2001, General Motors introduced a new transmission designated
THM 4L65E
with many engineering changes.  This unit is found in any vehicle with
5.3L
or a
6.0L
engine that was previously equipped with the THM
4L60E
transmission.  We will also cover the changes in the THM
4L65E
transmission in this booklet.
For the 2006 model year the
4L70E
was introduced to be used behind the 6.0L or larger gas engines which received heavier duty parts to handle additional horsepower.
There is no external way to distinguish the
4L70E
from the
4L65E
, however, the vehicle identification tag should have an M70 designation if the vehicle was originally equipped with a
4L70E
. Also included will be the additions the
4L70E
transmission received.
