Noise and Vibration Analysis
A noise or vibration that is noticeable when the vehicle is in
motion MAY NOT be the result of the transmission.
If noise or vibration is noticeable in PARK and NEUTRAL with the
engine at idle, but is less noticeable as RPM increases, the
vibration may be a result of poor engine performance.

Vibration may also be caused
by a small amount of water inside the converter. |

transmission mounts for damage and loose bolts. |

- |
Imbalance caused
by heat distortion or fluid contamination |
| • |
If the noise or vibration is
noticeable in PARK and NEUTRAL with the engine at idle, but is more
noticeable as RPM increases, the vibration may be an engine
imbalance or a transmission imbalance. Refer to
