Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Programming The TRID Block For A Replacement TCM
The TRID block on a replacement TCM is blank and requires programming. There are two procedures available. The first is an automatic data transfer from the old TCM to the new TCM and the second is manual data entry into the new TCM.
Automatic data transfer is carried out if the old TCM is capable of communicating. This is done by the use of a scan tool to retrieve data from the old TCM before removing it from the vehicle. The stored data can now be downloaded to the new TCM after it is replaced.
Carry out manual data entry if the old TCM is damaged or incapable of communicating. Remove and install a new TCM. Using a compatible scan tool, select and carry out the module/parameter programming, referring to the manufacturer's instruction manual. Make certain that all parameters are included. Failure to correctly program certain parameters may result in DTCs. You may be instructed to contact the As Built data center for the information needed to manually update the TRID block with the scan tool. Contact the center only if the old TCM cannot be used or the data is corrupt. For Ford and Lincoln technicians, contact the National Hotline or Professional Technician Society (PTS) website for As Built data. Non-Ford technicians, use the Motorcraft website at motorcraft.com. From the Motorcraft homepage, use the search function to find the Module Programming.
