2003 Chrysler 300M BaseSECTION 42LE Transmission Verification Test VER-1
NOTE: If Transmission Control Module/Powertrain Control Module (TCM/PCM) or torque converter was replaced, or transmission has been repaired or replaced, reprogram pinion factor and perform shift quality quick learn procedure. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION. If the torque converter or the PCM is replaced on a vehicle whose torque converter has less than 3750 miles and less than 360 minutes of Partial Electronically Modulated Converter Clutch (PEMCC), then with the DRBIII® scan tool, restart the TCC Break-In. This is in order to avoid possible shudder.
  1. Inspect vehicle to ensure that all engine components are properly installed and connected. Reassemble or reconnect components as necessary.
  2. Connect DRBIII® scan tool to Data Link Connector (DLC). Using DRBIII® scan tool, erase all transmission DTCs and PCM DTCs.
  3. Using DRBIII® scan tool, display Transmission temperature. Start and run the engine until the Transmission temperature is Hot, above 110°F (43°C).
  4. Check transmission fluid and top off fluid as necessary.
  5. Road test vehicle. Using DRBIII® scan tool, monitor the engine RPM. Make 15 to 20 1-2, 2-3 and 3-4 upshifts. Perform these upshifts from a standing start to 45 MPH with a constant throttle opening of 20-25 degrees.
  6. While driving at less than 25 MPH, make 5 to 8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds in 2nd and 3rd gears between each kickdown.
  7. For a specific DTC, drive vehicle under conditions that were present when DTC was set. If equipped with Autostick®, upshift and downshift several times using the Autostick® feature during the road test.
  8. Use the EATX OBD-II 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.
    9. NOTE: Erase DTC P0700 in the PCM after making transmission repairs. This will turn the MIL off.
  9. 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 .
