The sift solenoids are located on the valve body inside the transmission.

Removal of the transmission filter will grant you a clearer view as well.
This is a 4L60E transmission, in the event you have not purchased the solenoids.

check or replace your thottle position sensor tps that trans needs to know where the throttle is to shift if it is bad it will do as you say wont shift to third
another telltale is it will act like it goes into lockup when shifting into reverse and stall the engine
