But, maybe you mean they're talking to each other and working good together 'cause the rig is still running down the road fine, just no data being sent to the speedo, tach and other gauges.

That is exactly what I am saying... The Engine and transmission wouldn't be happy if they weren't able to communicate with each other. Because it seems to run fine and the transmission is working like it should, I am assuming that they are communicating.
