Product Overview
This DOWNLOAD of the 4L60E/4L65E/4L70E TechTran will address the diagnostics, disassembly and assembly of the 4L Series from the 2009 model year to the 2014 model year.
The General Motors 4L60E/4L65E/4L70E transmissions were produced from its introduction for the 1993
model year until its final production model year of 2014 which is a 21 year run. For the 1993 model year the
4L60E was used only in half ton trucks and vans. For the 1994 model year its use was extended to some
passenger cars. GM's 4L, 4-speed longitudinally mounted transmission with a strength rating of 60, 65 and 70 was
designated with an E to indicate that it is electronically controlled. However, since its inception in 1993, this
transmission has received an endless list of changes and updates.
The Green Update Manual provides the many changes that took place throughout these years. Changes made to the case, the pump and the addition of the Input Shaft Speed Sensor are some of what can be found in this manual "Update Handbook" which we highly recommend alongside the TechTran Manual for a proper overhaul or repair.
