Flywheel Noise (Automatic Transaxle)

A loose or cracked flywheel will produce an irregular thud or click. To test for a loose or cracked flywheel, operate the vehicle at approximately (32 km/h) 20 mph and shut off the engine. If a thud is heard, the flywheel may be loose or damaged. This type of thud is loudest on deceleration.

Loose torque converter-to-flywheel or flywheel-to-crankshaft bolts will sound similar to bearing knock. This condition produces several raps during quick acceleration on a free running engine. Depending on the idle smoothness, when the transaxle is in gear, the noise may or may not appear. Check the torque converter to flywheel and flywheel to crankshaft bolts before attempting to investigate any bearing-related knock.

NOTE: Be sure the converter to flywheel bolts are not too long. Converter bolts that are too long may dimple the torque converter clutch apply surface causing a shudder condition.
