The proper sequence to bleeding any brakes, are usually to do the one farthest away from the master cyl. first, and continue till ur at the last one. (left front). Rear brakes, then to the front brakes!

I have the same year Suburban and last year I had the same problem. I was told by a mechanic that it could be the Throttle Position Sensor, replaced it and now it shifts perfectly.
code 28 is transmission range pressure switch, check the fluid level and get back to me, hope this helps. Please rate my fix as i strive to be the best Thanks Ray
Code 78 refers to the secondary fan relay circuit, I would start there, you might have a short in that circuit, or an open, or bad relay. Hope this helps, let me know
well that is a great question
the only problem is that you would need a modis computer to bleed the ABS module on a Gm vehicle they have it in the PCM of your vehicle and its an option when the vehicle is plugged in at a shop..
this should not cost more than $25 to plug it in unless they are tryin to rip you off...
if you need any other info just replay ill check in later on
if rear wheel drive the combination valve has be held open.you have to have a combination valve depressor tool .you need a scanner to do abs brake functional test.
