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

While we wait for somebody like Nick to weigh in on the transmission questions, I can offer you this:

1. Vent hoses typically go from the transmission upwards and terminate, frequently attached near one of the upper bellhousing studded bolts. The idea here is to keep the vent up high in case that pothole ends up being deeper than your transmission

2. I've rebuilt transmissions up through the 700R4, but not these newer modern ones. My understanding is if you replace it in the driveway, you need to have it towed somewhere to have the transmission programmed. I guess bad things happen if you start it without doing that.
