naumann, OK - You are talking about the "
Transmission 5 to 3 downshift" program change. Yes a number of people have had that done to their vehilces. If I can have the last 8 digits of your VIN#, I can check to see if that was applied to your vehilce.
Know that the TCM needs to updated by Allison and that the ECM needs to be updated by a WCC Service Center (so equipped). In that order.
This is a TSB and not a recall.
