ATSG Tech Manual 4L60E Updated Handbook
Our ATSG GM THM 4L60-E 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!
This is the one that all the shops use. If you have plans to rebuild your transmission yourself, I would highly recommend this manual. It's extremely easy to follow and has great illustrations.
