41TE (NGC) TRANSMISSION VERIFICATION TEST - VER 1

APPLICABILITY

1. NOTE: After completion of the Transmission Verification Test, the Powertrain
Verification Test must be performed. Refer to the Powertrain Category.
2. Connect the DRBIII

t to the Data Link Connector (DLC).

3. Reconnect any disconnected components.
4. With the DRBIII

t, erase all Transmission DTC’s, also erase the PCM DTC’s.

5. Perform *PRNDL FAULT CLEARING PROCEDURE after completion of repairs for P0706
CHECK SHIFTER SIGNAL.
6. With the DRBIII

t, display Transmission Temperature. Start and run the engine until the

Transmission Temperature is HOT, above 43° C or 110° F.
7. Check the transmission fluid and adjust if necessary. Refer to the Service Information for the
Fluid Fill procedure.
8. 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
DRBIII

t Quick Learn Procedure and reset the (Pinion Factor(

9. Road test the vehicle. With the DRBIII

t, 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 is repaired.
12. If equipped with AutoStick

t, upshift and downshift several times using the AutoStickt

feature during the road test.
13. 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.
14. 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.
15. NOTE: Erase P0700 DTC in the PCM to turn the MIL light off after making
transmission repairs.
