Starting in 2009, 4L60E, 4L65E, 4L70E no longer has a TFP (Trans Fluid Pressure Switch) assembly, and is replaced by the trans range sensor. (also called IMS, internal mode switch) Prior to 2009, the range sensor was located on the outside of the trans, over the manual shaft.  It is now located INSIDE the trans.  Below are 2009 schematics for the 4L60E in a C/K truck platform.  The 3-2 downshift solenoid was also removed. These changes would lead me to believe you WILL NOT be able to use a 2009+ 4L60, 65, 70E whatever you want to call it in older applications.  You MIGHT be able to use a 2007 & older design valve body assembly, but unsure.
