Noise and Vibration Analysis

A noise or vibration that is noticeable when the vehicle is in motion, MAY NOT be the result of the transaxle.

If noise or vibration is noticeable in "PARK" and "NEUTRAL" with engine at idle, but is less noticeable as rpm increases, the cause may be from poor engine performance.
