You did not take it to a "qualified Crossfire mechanic", you took it to someone who might THINK they are, but no. What you are describing is a fundamental issue with the RCM. The Traction Control relay output from the RCM has failed - he should have seen thru this in a few minutes. The Traction Control has to be powered up for the speedometer and odometer to work, there can be various failures that cause the Cruise and ABS errors, but a failed speedometer tells me the Traction Control output from the RCM has failed.
I can prove this by yanking the fuse from the Traction control - you will get exactly what you describe. Again, anyone reading this can prove what is going on by yanking the Traction Control fuse on the RCM. If the car is a manual, you get these symptoms. If the car is an automatic, you won't be able to shift from PARK.
If its an auto and you CAN shift from PARK, then I am wrong and you found a new failure scenario.
