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!
