    SOLVED! It was a bad connection on one of those two wires between the VSSB and the computer. Which is weird because I DID check those wires visually and I'm positive I tested continuity on both, but it was definitely the problem. I used the splice connectors that have the ring of solder in the middle - I think it didn't melt when I installed it originally. This time I made sure the strands intertwined and made sure the solder melted. All four forward gears again!

    Great job on your diligence :) That volt/ohm meter only checks with the slightest amount of current so it cannot possibly show anything but a short or open circuit. Some times we have to go back to logic and with wiring there are many times where you just replace. Chasing an electrical gremlin is chasing what you cannot see at times :)
    Make sure you do a "twisted wire" on any sine wave connection.
