Noise and Vibration Analysis

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 cause may be from poor engine performance.

^ Inspect the tires for these conditions:
^ Uneven wear
^ Imbalance
^ Mixed sizes
^ Mixed radial and bias ply

^ Inspect the suspension components for these conditions:
^ Alignment and wear
^ Loose fasteners
^ Inspect the engine and transmission mounts for damage and loose bolts.

^ Inspect the transmission case mounting holes for these conditions:
^ Missing bolts, nuts, and studs
^ Stripped threads
^ Cracks

^ Inspect the flywheel for these conditions:
^ Missing or loose bolts
^ Cracks
^ Imbalance
