Transmission Vent hose line routing, Shifter cable too loose on 2wd Yukon

[IDontOwnAYukon]

I do not know if i am missing a bracket or something, but i am completley unable to find why my shifter cable is so damn loose. I must have lost a bracket, but I just cant find it anywhere. Additionally, Only one side of the transmission vent line is connected to anything, as the other sections are just fastened to the chassis. is this a correct routing? Its a 5.3 with the 6l80, but its a 2WD. Here are some photos. Any help would be greatly apprecieated. If anyonehas any diagrams, that would be a lifesaver. This is my first time working on a GM product ever, and have started witha transmission replacment, radiator, rear main seal, oil pressure sending unit, and oil pan gasket in my driveway, so if anyone has any of those diagrams that would be amazing. again, 014 GMC yukon XL SLT 2WD with the 5.3, no towing package
