40/41TE PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

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

1. Many transmission symptoms can be caused by a low fluid level. If the fluid level is low, locate and repair any leaks and fill the transmission to the proper fluid level. Refer to the Service Information for the proper repair and fluid fill procedures.
2. Testing should only be performed with the battery fully charged to avoid false diagnosis.
3. With the scan tool, read Engine (PCM) DTCs. If Engine DTCs are present, refer to the Engine Performance Diagnostic Information and perform to the appropriate diagnostic procedure(s) before proceeding.
4. With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information. Diagnose any Pending DTC as a matured DTC.
5. With the scan tool, read and record any DTC EVENT DATA. Use this data to help identify the conditions in which the DTC was set.

Note. Event Data may exist even if no DTCs are stored. Clearing DTCs does NOT erase the Event Data. To erase Event Data information you must either with the scan tool perform a Quick Learn procedure, battery disconnect (if available), or manually disconnect the battery. Whatever method used can reset some learned transmission values to controller defaults. This may cause poor shift quality until those values are relearned. Most DTCs require two "bad trips" before they are stored and the MIL illuminates. The transmission may enter "limp-in" mode during the first bad trip. However, if the fault condition is not present in the next ignition cycle and a "good trip" has been completed, the one trip or "pending" DTC may be cleared. The pending DTC information will be stored in the Event Data even though the scan tool shows no DTCs present. If the customer reports a limp-in event and no DTCs are present, check the Event Data.

1. With the scan tool, perform the Shift Lever Position Test. If the test does not pass, refer to the diagnostic procedure for P0706-Transmission Range Sensor Rationality.
2. For Gear Ratio Error DTCs, use the scan tool to read and record the Clutch Volume Index (CVI) information.
3. Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, driving under specific conditions, or after controller diagnostic monitors have run.
4. Refer to applicable Technical Service Bulletins (TSBs) for controller software update information. Some conditions can be corrected by upgrading the Engine (PCM) or Transmission (TCM) controller software.
5. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply.

1. Were there any repairs made that fixed the vehicle? Yes Testing complete. Perform the 40TE TRANSMISSION VERIFICATION TEST. Refer to «40/41 TE TRANSMISSION VERIFICATION TEST»(ref-485570-S08458558962012071300000) . No Refer to the «DIAGNOSTIC CODE INDEX»(ref-485570-S11451065552012071300000) and perform the appropriate diagnostic procedure(s).

1. Connect the scan tool to the Data Link Connector (DLC). Reconnect any disconnected components. With the scan tool, erase all Transmission and Engine Diagnostic Trouble Codes (DTCs). NOTE: Erase DTC P0700 under engine to turn off the MIL light after completion of transmission repairs. Perform *PRNDL FAULT CLEARING PROCEDURE after completion of repairs for P0706-TRANSMISSION RANGE SENSOR RATIONALITY. If the Powertrain Control Module or the Transmission has been repaired or replaced, it is necessary to perform a Quick Learn procedure with the scan tool. If the Torque converter has been replaced, with the scan tool perform TCC BREAK-IN. If the Powertrain Control Module (PCM), Front Control Module (FCM) or Totally Integrated Control Module (TIPM) has been replaced you must reset the Pinion Factor in the Front Control Module. With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Temperature is HOT, above 43° C (110° F). Check the transmission fluid and adjust if necessary. Refer to the Service Information for the Fluid Fill procedure. Road test the vehicle. With the scan tool, monitor the engine RPM. Make 15 to 20 1-2, 2-3, 3-4 upshifts. Perform these shifts from a standing start to 72 Km/h (45 mph) with a constant throttle opening of 20 to 25 degrees. With speeds below 40 Km/h (25 mph), make 5 to 8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown. For a specific DTC, drive the vehicle to the symptoms When Monitored/Set condition(s) to verify the DTC is repaired. If equipped with AutoStick®, upshift and downshift several times using the AutoStick® feature during the road test. NOTE: Use the OBDII task manager to run a Good Trip in each gear, this will confirm the repair and ensure that the DTC has not re-matured. Check for any DTCs during and after the road test. NOTE: Most DTCs require two "bad trips" before they are stored and the MIL illuminates. The transmission may enter "limp-in" mode during the first bad trip. However, if the fault condition is not present in the next ignition cycle and a "good trip" has been completed, the one trip or "pending" DTC may be cleared. The pending DTC information will be stored in the Event Data even though the scan tool shows no DTCs present. If the customer reports a limp-in event and no DTCs are present, check the Event Data. Did any DTCs set during the road test? Yes Refer to the «DIAGNOSTIC CODE INDEX»(ref-485570-S11451065552012071300000) and perform the appropriate diagnostic procedure(s). No Repair is complete.
