Transmission Verification Test

NAG1 TRANSMISSION VERIFICATION TEST - VER 1
1.
Reconnect any disconnected components.
Connect the scan tool to the Data Link Connector. With the scan tool, erase ABS DTC's. With the scan tool, erase PCM DTC's. With the scan tool, erase TCM DTC's. With the scan tool, display the Transmission temperature. Start and run the engine until the Transmission temperature is above 430°C (1100 F).
Check the Transmission fluid and adjust if necessary.

NOTE: If internal repairs were performed and the shift quality is still poor, it may be necessary to check the internal repair.

If the TCM (EGS) is flashed or replaced, with the scan tool, perform a EGS initialization to relearn variant coding. If internal transmission repairs are performed or replacement of the Transmission Control Module, perform a TCM ADAPTATION procedure. (Refer to Body Control Systems / Testing and Inspection. Testing and Inspection)
ROAD TEST PROCEDURE
Road test the vehicle. Make fifteen to twenty 1-2, 2-3, 3-4, and 4-5 upshifts.
Perform these shifts from a standing start to 72 Kmh (45 MPH) with a constant throttle opening of 20 to 25 degrees. With speeds below 40 Kmh (25 MPH), make five to eight wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.
With the scan tool, read Transmission DTC's.
Were any Diagnostic Trouble Codes set?
YES >>Repair is not complete, refer to the Transmission category and perform the appropriate symptom.
