I have the Automatic Transmission Service Group manual (the best in the industry) for the 4l60e along with a DVD that goes through the whole teardown, inspection / cleaning and rebuild process for the 4L60E. I bought these with the intention to rebuild my own transmission but eventually decided to leave that to the people that have more time on their hands then myself. Picked these up last month for about $60. -- $40 shipped.

Comes with the ATSG manual and update and a very detailed DVD from Boxwrench.com.

 

Still available.
