Verification Tests
41TE TRANSMISSION VERIFICATION TEST - VER 1 APPLICABILITY
1. Connect the DRBIIItto the Data Link Connector (DLC).
2. Reconnect any disconnected components.
3. With the DRBIIIt, erase all Transmission DTC's, also erase the PCM DTC's.
4. NOTE: Erase DTC P0700 in the PCM to turn the Malfunction Indicator Lamp (MIL)
off after making Transmission repairs.
5. With the DRBIIIt, display Transmission Temperature. Start and run the engine until the
Transmission Temperature is HOT - above 43.33É C or 110É F.
6. Check the Transmission Fluid and adjust if necessary. Refer to the Service information for
the Fluid Fill procedure.
7. NOTE: If the Transmission Control Module or Torque Converter has been replaced
or if the Transmission has been repaired or replaced it is necessary to perform the
DRBIIItQuick Learn Procedure and reset the(Pinion Factor(
8. NOTE: If the Torque Converter is replaced, or if a TCM is replaced on a vehicle
whose Torque Converter has less than 3750 miles and less than 360 minutes of
PEMCC, then with the DRBIIItrestart the TCC Break-In. This is in order to avoid
possible shudder.
9. Road test the vehicle. With the DRBIIIt, monitor the engine RPM. Make 15 to 20 1-2, 2-3,
3-4 upshifts. Perform these shifts from a standing start to 45 MPH with a constant throttle
opening of 20 to 25 degrees.
10. Below 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.
11. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set
conditions to verify the DTC repair.
12. NOTE: Use the EATX OBDII Task Manager to run Good Trip time in each gear, this
will confirm the repair and to ensure that the DTC has not re-matured.
13. Check for Diagnostic Trouble Codes (DTC's) during the road test. If a DTC sets during the
road test , return to the Symptom list and perform the appropriate Symptom.
Were there any Diagnostic Trouble Codes (DTCs) set during the road test?All

SKIM.
2. NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret
Key data must be updated. Refer to the Service Information for the PCM, SKIM and
the Transponder (ignition key) for programming information.
3. Inspect the vehicle to ensure that all components related to the repair are connected
properly.
4. With the DRBIIIt, clear DTCs and Reset Memory all engine values.
5. Run the engine for one warm-up cycle to verify proper operation.
6. Road test the vehicle. Use all accessories that may be related to this repair.
7. With the DRBIIIt, confirm that no DTC's or Secondary Indicators are present and that all
components are functioning properly.
8. If this test is being performed after a No Trouble Code test, verify the symptom is no longer
present.
9. If the symptom is still present, or any other symptom or DTC is present refer to the
appropriate category and perform the corresponding symptom.
10. Refer to any Technical Service Bulletins that may apply.
11. If there are no DTCs present and all components are functional properly, the repair is
complete.
Are any DTCs present?All
Ye s®Repair is not complete, refer to appropriate symptom.
No®Repair is complete.
