4l70e to 4l60e Hey I have a 2008 gmc sierra vortecmax with a 4l70e. The 4l70e did not hold up. I have a built 4l60e from a 1998 gmc sierra I'd be looking to swap. What is needed to be done to actually make it work.

A 4L70E is a built 4L60E. What happened to the 70E?
I believe the 08s had an ISS (speed sensor) in the trans, so a direct swap isn't an option. I think you can tune around it, but some other guys with more experience will have to comment on that.
