Pay particular attention to all power and ground circuits. If no problems are found, replace the Shifter Lever Assembly in accordance with the Service Information. Refer to «SHIFTER, TRANSMISSION, REMOVAL»(ref-489308-S29149508352012072600000) . Perform the NAG1 TRANSMISSION VERIFICATION TEST. Refer to «NAG1 TRANSMISSION VERIFICATION TEST»(ref-489366-S27132934282012072600000) .

NAG1 PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

For a complete wiring diagram refer to appropriate SYSTEM WIRING DIAGRAMS article

Perform the following pre-diagnostic troubleshooting procedures prior to performing any diagnostic test.

Note. Due to different power control configurations, the Transmission Control Relay (if equipped) may be referred to as a PCM relay.

Note. Incorrect fluid level, and/or poor fluid condition can be the cause of many transmission problems. Visually inspect the transmission and cooler lines for leakage and repair as necessary and adjust the fluid level per the Service Information.

Always perform diagnostics with a fully charged battery to avoid false symptoms.

1. With the scan tool, read the engine DTCs. Check and repair all engine DTCs prior to performing transmission symptom diagnostic procedures.
2. With the scan tool, read and record all Transmission DTCs. Record the controller software version and variant ID (configuration or level). NOTE: Check for any Service Information Tune-ups or Technical Service Bulletins (TSB) that may apply. NOTE: If the TCM detects and stores a DTC, the TCM also stores the vehicles operating conditions under which the DTC originally set. This information is located using a scan tool under Environmental Data. Before erasing any stored DTCs, it is recommended to record all available data to assist in troubleshooting and duplicating the conditions and in which the DTC originally set.
3. Verify the current software level of transmission controller. Various problems are corrected by software upgrades (flash) to the transmission controller. NOTE: If a TCM software update is performed, all DTC information (Environmental Data) will be lost.
4. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors to all components related to the transmission and shift lever assembly. Clean and repair as necessary.
5. Most DTCs set on start up but some may only set by driving the vehicle. Note the when monitored and set conditions of the reported DTC. If variant DTCs are present, perform their respective test first.
6. Verify the axle ratio and transfer case ratio. NOTE: The Transfer case ratio must be programmed using the scan tool under the appropriate gateway module (FCM, FDCM, and/or TIPM) even if equipped with AWD or NO transfer case. Validate that the left to right tire sizes on each axle are the same. Do not perform diagnostics using a space-saver spare tire. Invalid tire sizes (right to left) may cause erroneous DTCs to set.

1. Did any of the above procedures repair the vehicle? Yes Testing is complete. Perform the NAG1 TRANSMISSION VERIFICATION TEST. Refer to «NAG1 TRANSMISSION VERIFICATION TEST»(ref-489366-S27132934282012072600000) . No Refer to the appropriate Electrical Diagnostic Information and perform the appropriate symptom(s).

NAG1 TRANSMISSION VERIFICATION TEST

To validate that the repair(s) fixed the vehicle, perform the following steps.

1. Reconnect any disconnected components.
2. Connect the scan tool to the Data Link Connector.
3. With the scan tool, erase ABS DTCs.
4. With the scan tool, erase PCM DTCs.
5. With the scan tool, erase TCM DTCs. CAUTION: Apply the parking brake. NOTE: The Transmission Temperature can only be read while in Reverse or Drive.
6. With the scan tool, display the Transmission temperature. Start and run the engine until the Transmission temperature is above 43° C (110° F).
7. If internal transmission components were repaired or replaced check the Transmission fluid and adjust if necessary. Refer to the Service Information for the proper Fluid Fill procedure. Refer to «FLUID AND FILTER, STANDARD PROCEDURE»(ref-489308-S36615165542012072600000) .
8. If the TCM (EGS) is flashed or replaced, with the scan tool, perform an EGS initialization to relearn variant coding.
9. If internal transmission repairs are performed or replacement of the Transmission Control Module, perform a TCM ADAPTATION procedure. Refer to «MODULE, TRANSMISSION CONTROL, STANDARD PROCEDURE»(ref-489300-S42485579262012072600000) .
10. After performing the above procedures, perform the Road Test Procedure.

ROAD TEST PROCEDURE

1. Road test the vehicle. Make fifteen to twenty 1-2, 2-3, 3-4, and 4-5 upshifts.
2. Perform these shifts from a standing start to 72 Km/h (45 mph) with a constant throttle opening of 20 to 25 degrees.
3. With speeds below 40 Km/h (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.
4. With the scan tool, read DTCs.

1. Did any DTCs set? Yes Refer to the appropriate Electrical Diagnostic Information and perform the appropriate symptom(s). No Testing is complete.
