SYMPTOM/CONDMON
Customer concern of "rattling" noise from transaxle area with clutch pedal out, transaxle in neutral, and engine at curb idle.
DIAGNOSIS/REPAIR
The engine and transaxle should be at their normal operating temperatures. With the engine idling, transaxle in neutral, and the clutch pedal out, listen
for gear rattle. Raise the engine idle speed slightly to see if the noise disappears. If the noise disappears, then attach a tachometer to the engine and check
the curb idle speed per Driveability Test Procedure. Adjust the idle speed to the recommended idle speed (i.e., if recommended curb idle speed is 800 +/-
100 rpm, and actual idle speed is 725 rpm, then adjust the idle speed to 800 rpm). As little as 50 rpm can make a big difference in the gear rattle sound.
CAUTION: NEVER ADJUST THE IDLE SPEED ABOVE THE RECOMMENDED RPM RANGE TO REDUCE GEAR RATTLE
If the customer is complaining of neutral gear rattle only when the steering gear is placed in a full turn against the stops (vehicles equipped with power
steering), or during air conditioning clutch engagement or any other condition that lowers the engine idle speed below the normal idle speed, the noise is
considered normal and no attempts should be made to repair it. Neutral gear rattle is not detrimental to vehicle components or operation.
