Preliminary Inspection

WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Transaxle malfunctions may be caused by poor engine performance, improper adjustments or failure of hydraulic, mechanical or electronic components. Prior to diagnosing transaxle concerns, always begin by checking fluid level, fluid condition and shift cable adjustment. Ensure engine starts with gearshift lever in Park and Neutral to ensure proper adjustment of park/neutral position switch. Ensure all system-related fuses are okay. Check wire harnesses for proper routing. Verify all harness and component connections are clean and tight. See WIRING DIAGRAMS  . If area of fault cannot be located or repaired during preliminary inspection, check self-diagnostic system. See SELF-DIAGNOSTIC SYSTEM  . Repair as necessary.

Perform road test to determine if problem has been corrected. See ROAD TEST  under PERFORMANCE TESTS. If problem still exists, diagnose by symptom. See SYMPTOM DIAGNOSIS  .
