Description of Repair unable to perform
Programming of replacement TCM while installed on aftermarket reman DT12 transmission.
Description of Information not available
The vehicle owner purchased an aftermarket remanufactured DT12 transmission and, separately, a new OEM etroit Diesel DT12 Transmission Control Module from Freightliner. The owner installed said parts and brought the truck to a Freightliner dealer for TCM programming to VIN. The dealership attempted to program the TCM, but somehow Detroit Diesel learned of the remanufactured DT12 transmission and locked this specific VIN out from any transmission service in Detroit Diagnostic Link software. To unlock the VIN for service, the owner had to purchase and install an OE Detroit Diesel transmission. The owner did purchase the OE transmission, the VIN was unlocked, programming completed at the Freightliner dealer, and the truck released. The owner had to turn his remanufactured DT12 for core credit to Detroit Diesel.
Description of steps taken to obtain information (help/contact function on website, websites, etc.)
Servicing dealership and vehicle owner's account of the transaction with Detroit Diesel.
Other Comments or Concerns
OEM's should not be permitted to lock out required service to vehicles based on aftermarket parts being installed. This was not an OEM warranty issue, the vehicle was out of powertrain warranty.
