31TH Transmission Verification Test VER-1

  1. Connect scan tool to Data Link Connector (DLC). Reconnect any disconnected components. Using scan tool, clear DTCs from Powertrain Control Module (PCM). Check transmission fluid level. Adjust fluid level, if necessary.
  2. Road test vehicle. Using scan tool, monitor engine RPM. Test drive vehicle from a stop to 45 MPH with a constant throttle opening of 20-25 degrees 15-20 times, allowing transmission to upshift through all gears.
  3. While driving at less than 25 MPH, make 5-8 wide open throttle kickdowns to 1st gear, allowing 5 seconds in 2nd and 3rd gears between each kickdown.
  4. For a specific DTC, drive vehicle under conditions that were present when DTC was set. Check for DTCs during road test. If no DTCs set, repair is complete. If a DTC sets, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  .
