Transmission DTC Verification Test
NOTE:
If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Controller Anti-Lock Brake (CAB) module, Air Bag Control Module (ACM) and Sentry Key Immobilizer Module (SKIM). If replacing PCM and vehicle is equipped with SKIM, secret key data must also be updated to enable engine starting. See PROGRAMMING
.
- Inspect vehicle to ensure that all engine components are properly installed and connected. Reassemble or reconnect components as necessary. If all DTCs have been repaired, go to next step. If any DTCs have not been repaired, perform appropriate diagnostic procedure. See DIAGNOSTIC TROUBLE CODE DEFINITIONS .
- Connect scan tool to Data Link Connector (DLC). Ensure fuel tank is at least 1/4 full. Turn all accessories off. Start engine and run until transmission temperature is more than 110°F (43°C). Check transmission fluid level. Adjust if necessary.
- 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.
- 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.
- 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 .
