Transmission Verification Test
NOTE:
If Transmission Control Module (TCM) or torque converter was replaced or transmission has been repaired or replaced, scan tool must be used to perform quick learn procedure.
- Remove all test equipment and jumper wires. Connect any disconnected components. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Using scan tool, clear Diagnostic Trouble Codes (DTCs) from all modules. Using scan tool, check transmission temperature. Start vehicle and let idle until transmission temperature is greater than 110°F (43°C). Go to next step.
- Check transmission fluid level and adjust as necessary. Using scan tool, monitor engine RPM. Test drive vehicle from a stop to 45 MPH with throttle at approximately 20 degrees 15-20 times, allowing transmission to upshift through all gears. Go to next step.
- Driving below 25 MPH, make 5-8 wide open throttle kickdowns to 1st gear, allowing 5 seconds in 2nd and 3rd gears between each kick down. Using scan tool, retrieve DTCs from all modules during test drive. If no DTCs exist, system is operating correctly and customer's complaint cannot be duplicated, repair is complete. If any DTCs exist, perform appropriate test. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION table under SELF-DIAGNOSTIC SYSTEM.
