Manual Shifting Test
NOTE:
Perform manual shifting test if no trouble codes are present. Manual shifting test determines if problem is an electrical or mechanical related problem.
- Start and operate vehicle until normal operating temperature is achieved. Disconnect TCM harness connector. See Figure. Road test vehicle and ensure transmission gear changes correspond with shift lever position. See GEAR APPLICATION table.
- If an abnormality is present, problem is mechanically related. If all gears are correct, perform trouble shooting in accordance with symptom. See SYMPTOM TROUBLE SHOOTING . Turn ignition off.
- Reconnect TCM harness connector. Clear trouble codes from TCM memory, as disconnecting electrical connector may set a trouble code. See CLEARING TROUBLE CODES .
