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...

That's nothing - Our friends in Australia get a cool digital cluster that has the ability to display fuel efficiency, but it's not active either. When you are designing something like a cluster, you add all of the hardware up front, and then in software you enable it as you see fit. You never want to have to go back and redo the hardware if you can avoid it. The problem though, is that upgrading the cluster SW is not a field doable thing.
