Automatic transmission whine noise is an indication of a serious transmission problem occurring from inside. Most transmission noise problems are due to a very low A/T fluid inside the transmission. However, when the automatic transmission fluid is within the normal level, then expect a very serious problem that causes growling noise such as damaged or worn out transmission components.
Whining noise is a result of the incorrect rotation of transmission components such as bearings or gears that comes in contact with other components inside the transmission. Now, why did these components rotate incorrectly? The reason is the parts might have damaged or extremely worn out bearing or gears, this is only a possibility and to identify the real culprit the parts must be checked in actual.
