The ATSG Comprehensive OBD2 Diagnostic Guide for The 4L60E,65E,70E & 4l80E,85E Trans

[mrrsm]

This is a VERY comprehensive 185 Page PDF Service Guide covering the OBD2 Diagnostics for The GM 4L60E, 4L65E, 4L70E, 4L80E and 4L85E Transmissions. It contains a great many contributions from the Members of the GM Automatic Transmission Service Group (ATSG) imparting arcane knowledge, tips and tricks offered up by the many Professionals working in this largely mysterious branch of Automotive Repairs; one not usually accessible to most of us. THIS one is definitely a 'Download and KEEP' kind of a Document:

The PDF is 4 Megabytes in size and is a 185 Page Long Document. It may be that you need to Download this information onto a Laptop Computer First. I cannot imagine having to read the Text and View all of the nested Images on a Cell Phone within this densely packed PDF ... unless you have absolutely Perfect Eyesight.

Note that it won't affect many here if you have a TB... but... if you're 2008 and above, you need the manual that came after this.

There were a few changes starting '08.
