Gear Vendors OD electrical help

[J-440]

When I turn on my ignition, both the underdash lights from the switch (red/green) flash on and off once. I can see that the "brain/ECU" is lit also with 3 small lights. I take my car up to 47mph in Auto mode, press the shifter button and nothing. I've been up to 55 and still it won't upshift. The GV website states that the red light is supposed to come on to let you know when it's ready to shift. I get nothing.
I'm gonna dive into this thing here in a sec and just want some advice on what to look for. My electrical skills are about as good as dressing like a millennial...not very good. Any advice is appreciated.
