Transmission Verification Test

• After completion of the transmission verification test, the Powertrain Verification Test must be performed. Refer to => [ PCM Verification Test ] PCM Verification Test.

• Connect the scan tool to the DLC.

• Connect any disconnected components.

• With the scan tool, erase all transmission and engine DTCs.

• Erase DTC P0700 under engine to turn off the MIL light off after completion of transmission repairs.

• Perform *PRNDL Fault Clearing Procedure after completion of repairs for DTC P0706.

• If the PCM or the transmission have been repaired or replaced, it is necessary to perform the scan tool Quick Learn Procedure.

• If the torque converter has been replaced, perform the TCC Break-In with the scan tool.

• If the PCM or TIPM has been replaced you must reset the pinion factor in the TIPM.

• With the scan tool, display the transmission temperature. Start and run the engine until the transmission temperature is above 43 °C (110 °F).

• Check the transmission fluid and adjust if necessary.

• 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 45 MPH with a constant throttle opening of 20 to 25 degrees.

• With speeds less than 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 Symptom's When Monitored/When Set conditions to verify the DTC is repaired.

• If equipped with AutoStick(R), upshift and downshift several times using the AutoStick(R) feature during the road test.

• Use the OBDII task manager to run a good trip in each gear, this will confirm the repair and to ensure that the DTC has not re-matured.

• Check for any DTCs during and after the road test.
