Well, here's something a little funky while I'm still waiting to test the Mikado in a Command enviroment.
I've completed one of the two Command upgrades to my SD40-2's. That one, I used the Cruise Commander. The thing is this one did cycle forward/neutral/reverse as per expected in conventional mode.
In addition to testing in the Command enviroment, I'm going to have to look into the engine again just to be sure the wires weren't crossed, and hopefully I didn't blow the DC Commander with that or some stray static electricity...
