Question for those with a 2007 automatic

So, it's the 07 cluster that doesn't respond to gear change CAN message, rather than the 07 ECM not sending it.

Now this is starting to get interesting. Why would the cluster "have" a spot for the gear selection, the ECM is sending the signal, but it's not active?

Weird...
