VERIFICATION TESTS
31TH 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 the PCM DTC's.
4. Check the transmission fluid and adjust if necessary. Refer to the Service information for the
Fluid Fill procedure.
5. Road test the vehicle. With the DRBIIIt, monitor the engine RPM. Make 15 to 20 1-2, 2-3
upshifts. Perform these shifts from a standing start to 45 MPH with a constant throttle opening
of 20 to 25 degrees.
6. 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.
7. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set conditions
to verify the DTC repair.
8. 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 follow the path.
Were any Trouble Codes set during the road test?All
Ye s®Refer to the Symptom List for appropriate diagnostic tests.
No®Repair is complete.
41TE TRANSMISSION VERIFICATION TEST - VER 1. APPLICABILITY

5. Check the transmission fluid and adjust if necessary. Refer to the Service information for the
Fluid Fill procedure.
6. 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(
7. 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.
8. 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.
9. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set conditions
to verify the DTC repair.
10. 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 follow the path.
11. NOTE: Erase P0700 DTC in the PCM to turn the MIL light off after making
transmission repairs. This will turn the MIL off.
