4L60E question
Please explain in much more detail. I should then be able to answer any 4L60E compatibility or conversion question. I may move it to the Automatic Transmission section.
2008-up 4L60E is different from the 07-back, different electronics. So no a 2007 unit will not work in plce of a 2009 unit.
Wouldn't hurt to move it to the Auto Trans section since this is specific to that.
Here's a thread that may have some info..

Of course that doesn't @the_merv conclusion that a 2007 and 2009 are not interchangeable.
However, I was wondering if maybe the OP wanted to modify a 2009 to be 2007 compatible or vise-versa. (Yes it can be done by swapping valve bodies, harness and a few other parts.)
I'm going to leave this thread here, because this is "well known" in the Automatic Transmission section.
