What would stop them from being able to light the logo when its in park, then have it disabled while in motion?
Other than the Camaro ZL1, GM doesn't have the 10 speed in anything else yet. Ford will have their version of the 10 speed across more of their lineup by MY2018 than GM will. As to the 9 speed, I'm not entirely sure what the delay is on Ford's end. Perhaps it just simply isn't ready yet. As much trouble as Ford has had with FWD transmissions over the last decade, it makes sense to wait a bit and make sure they get it right the first time.
