P0734

Out for a cruise today and about an hour in I got a CEL. My rev match kicked off and wouldn't re-engage. I got the service the Parking Brake symbol. The engine sound reverted to the default setting even though I was in track mode and under settings, sound management was set to track. I felt no loss of power. Took the car home and shut it off. After restarting, rev match worked normally, the service parking brake symbol went away and engine sound returned to normal. Pulled the code and it is P0734. Any ideas?

Thanks,
Mike

Do you happen to have an after market shifter? The code means that the measured gear ratio doesn't match the gear position sensor indication.
