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 a noise or vibration is noticeable in P (park) or N (neutral) positions with the engine at idle, but is less noticeable and engine RPM increases, the cause may be from poor engine performance.
