2004 Suburban LTZ transmission swap?

Yes, but OMG the issues and electronic problems would deem the benefit as void. The new Trannies are completely electronically controlled.
If you are trying to get better performance or con out of your ride the figure in a tranny kit and consider your rear gears.

I would probably stick with the same tranny the 4l80 or if you can get the 4l85 the 85 has more clutch packs and higher pressure and its valve body is designed for firmer shifts.
