What is your question?
Where is the physical location of the sensor/Solenoid for 2-3 shift? Transmission? How do you tell which one you have? Do I have 4L60E or 4L80E?

The shift solenoids for your 1999 GMC Yukon are located on the valve body, they are accessed by removing the transmission pan. A 4L60E is a lighter duty transmission and has an almost square oil pan. The 4L80E is a heavier duty transmission will a more rectangular oil pan which is kind of rounded at one end.
