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.
Solenoid Reprogramming Procedure
Perform solenoid characterization reprogramming after one of the following service procedures:
- Replace transmission assembly
- Replace control valve solenoid body
- Replace solenoid (currently not an available Service Procedure)
- Replace TCM
Select "Replace Transmission" at the MCVM Characterization selection screen.
Select "Replace Control Valve Solenoid Body" at the MCVM Characterization selection screen.
Select "Replace Solenoid" at the MCVM Characterization selection screen.
Select "Refresh Characterization Data" at the MCVM Characterization selection screen.
To perform solenoid characterization after a transmission component replacement:
- Document the new Transmission Unique Number (TUN). The TUN location may be found here: Transmission Identification Information . Since the TUN can be difficult to access when the transmission is installed in the vehicle, ensure you document the 16-digit TUN prior to installing the transmission in the vehicle.
- Use a generically available QR Code/data matrix scanner to obtain the Part Unique Number (PUN). The PUN location may be found here: Control Valve Solenoid Body Identification Information . Before installing the control valve solenoid body onto the transmission, scan the data matrix.
- Log into SPS.
- Type the vehicle identification number (VIN).
- Perform the SPS Transmission Control Module programming event.
- Select "Transmission Control Module - Programming" to update TCM calibrations and Solenoid Characterization data.
OR
- Select "Transmission Control Module - MCVM Operations" to update Solenoid Characterization data only.
- Select "Transmission Control Module - Programming" to update TCM calibrations and Solenoid Characterization data.
- From the "MCVM (Mechanical Characterization and Virtual Matching) Operation Selection" screen, select the applicable service procedure to be performed. You will be prompted to provide the necessary Transmission Unique Number (TUN) when replacing a transmission part.
At this point, the system will read the VIN from the engine control module (ECM) using the multiple diagnostic interface (MDI) and then retrieve the applicable genealogy data tree from the cloud. This data tree accesses the original characterization data so that it may be updated with the new component information. The system acquires characterization data for the given TUN/PUN via the cloud and updates the genealogy tree. The TCM is updated with the correct solenoid characterization data, and the cloud is updated with the new genealogy relationship.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
