2004 4l80e hot trans on hills

the truck is in the shop. 2 issues: leaking/sweating trans cooler lines, and power steering super leak. I temporarily cured by chemicals the power steering leak, and the trans line job will open up the cooler can of worms. I was monitoring the trans fluid ensuring that it was not low or actually leaking. The PS leak dripped one quart until cured by chemicals.

I am also having a sensor issue: mass air flow, left bank , and iirc knock sensor. I prior threw $300 into that CIL issue with new plugs, and injection clean out bandaid.
older tv woes.
