Honestly, you're going to have a tough time with this one. Your autoscan didn't even pick up the trans control module. Unplug the ABS module and see if you can communicate with the TCM, but this is the point where I would break out the lab scope, pin-outs, and ErWin account.

What's weird, is that I drove for 200 miles without a fault. Could this be the ABS module taking another sh*t on me again? So frustrated...

I would blame the wheel sensor, but I drove 200 miles after the rebuild of the ABS module (hinting that it was the module that was faulty). Same problems (no speedo, trac ctrl light, abs light, check engine).
