Little Black Box, Fuel Pump, Fuel Lines
it sounds like you have a line hooked up to the wrong spot, and that little black box sounds like the charcoal canister, which is used to filter out fuel vapors. it sounds like either the supply or return line has been hooked into the vapor line. retrace your steps, largest diameter line is supply, medium is return, smallest line is vapor line. good luck!

I looked at wiring diagrams at bbbindustries: the orange wire to the 20 amp htr fuse is direct from the ignition switch. You might check: that orange wire splices to the 10 amp brake fuse (fuse #12). check if that also has any voltage problems.
There are two black fusible links that supply power to the ignition switch. the fusible links come from the battery junction block.
Not getting proper voltage to transmission
first have the fault codes read--that saves a lot of cash and heart ache
next buy a workshop manual as that will show you where all the bits are that are from the fault codes
the codes found will indicate were the problem is
could be in the wires , servo/ solenoids or TCM
if there is nothing mechanical wrong with the transmission ( you haven't mention any problems ) then changing the transmission is a waste of time
knowing that it is a GM product and GM does not agree to transmission oil changes ( sealed transmissions) it is probably just dirty oil so a service could be the answer to your problems
Loss of power, studdering at high rpms when at temp.
Sound's like it break down due to no oil or water circulate
the engine. Or wrong spark plug gap. So it increase too much heat.
1. Flush the engine. Flush the coolant.
2. Check spark plug gap (Adjust to correct gap)
3. Check oil pressure. If it's low then new oil pump is need.
