Transmission Noisy: Notes

Many noises that appear to come from the transaxle may actually originate with other sources such as the tires, road surfaces, wheel bearings, or the engine and exhaust system.

Identify the cause of any noise before attempting to repair the clutch, the transaxle, or their related linkages.

To verify suspected transaxle noises,

1. Select a smooth, level asphalt road to reduce tire and resonant body noise.
2. Drive the vehicle far enough to warm up all the lubricants thoroughly.
3. Record the speed and the gear range of the transaxle when the noise occurs.
4. Check for noises with the vehicle stopped, but with the engine running.
CAUTION: Road test a vehicle under safe conditions and while obeying all traffic laws. Do not attempt any maneuvers that could jeopardize vehicle control. Failure to adhere to these precautions could lead to serious personal injury and vehicle damage.
5. Determine if the noise occurs while the vehicle operates in the following:
   • Drive - Under a light acceleration or a heavy pull.
   • Float - Maintaining a constant speed with a light throttle on a level road.
   • Coast - With the transaxle in gear and the throttle partly or fully closed.
   • All of the above
