Transaxle Noise
Transaxle gears, like any mechanical device, are not absolutely quiet and will make some noise during normal operation.
To verify suspected transaxle noises:
- Select a smooth, level asphalt road to reduce tire and resonant body noise.
- Drive the vehicle far enough to warm up all the lubricants thoroughly.
- Record the speed and the gear range of the transaxle when the noise occurs.
- Check for noises with the vehicle stopped, but with the engine running.
- Determine if the noise occurs while the vehicle operates in:
- 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.
