Why, for 2006 Suburban, is there no exploded diagrams, only lists by part number, or list by description ?

Example: https://www.gmpartsgiant.com/parts-l...M30;m=CK15906)

Alternatively, could someone point me to a URL having the 2006 exploded diagram for assemblies for 4L60E with transfer case extension ?

 

Thanks for the suggestion Tom. I was hoping to be ablel to find part# or at least the factory description of what I was looking for so I could find parts on Ebay or elsewhere. Not many choices for junkyards here that would have good examples of what I need- especially in winter.

 

Thanks for the link Joe, I'll try again. I'm not that good at navigating some of these sites.
