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.
