41TE Transmission Verification Test

NOTE: If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Controller Anti-Lock Brake (CAB), Smart Key Immobilizer Module (SKIM), if equipped and Occupant Restraint Controller (ORC). If replacing PCM and vehicle is equipped with a Smart Key Immobilizer Module (SKIM), secret key data must also be updated to enable engine starting.
  1. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If any DTCs have not been diagnosed, perform appropriate diagnostic test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If all DTCs have been diagnosed and repaired, go to next step.
  2. If repair procedure did not include replacing PCM, go to next step. If PCM has been replaced and has already been programmed, go to next step. If PCM has been replaced but has not been programmed, program PCM and clear DTCs. See PROGRAMMING . After PCM has been programmed, go to next step.
  3. Using scan tool, clear PCM and TCM DTCs. Using scan tool, monitor transaxle temperature. Start engine and allow it to run until scan tool displays transaxle temperature as HOT, above 110°F (43°C). Ensure transmission fluid is at proper level. Ensure all accessories are off.
    NOTE: If TCM or torque converter has been replaced or if transaxle has been repaired or replaced, reprogram pinion factor and perform shift quality quick learn procedure. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION.
  4. Road test vehicle. Using scan tool, monitor engine RPM. Make 15-20 1st-2nd, 2nd-3rd and 3rd-4th upshifts. Perform shifts from a standing start to 45 MPH with a constant throttle opening of 20-25 degrees.
  5. With vehicle speed less than 25 MPH, make 5-8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.
    NOTE: If any transaxle repairs were made, the Malfunction Indicator Light (MIL) may be on and DTC P0700 may be present. Using scan tool, clear DTCs. MIL should now be off.
  6. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set conditions to verify the DTC repair. Check the DTCs during the road test. If a DTC resets, proceed to appropriate DTC test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no DTCs reset, repair was successful and test is now complete.
