2. Select Use Controller Part Number under the Flash Tab.

3. Flash the controller with the correct software.

Were you to update (flash) the controller successfully?

Yes, test complete. Perform the NAG1 Transmission Verification Test.

No, using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the Transmission Control Module (TCM). Perform the NAG1 Transmission Verification Test.
