Troubleshooting car problem of whining noise when accelerating

Whining noise in most cases is caused by friction between the transmission components, a gear or a bearing may have an incorrect contact with each other. This will happen when these components have worn out or damaged. However, it is difficult to determine if it is really the cause without the inspection of the actual transmission. To confirm whether the whining noise is coming from the transmission do the following:

1) Drive the car to the speed in which the whining noise is observed. 2) Shift the gear to a neutral position then turn off the engine while it runs. 3) When the whining noise is still present then this confirms that the problem is within the transmission, but when the whining noise is not observed then the problem is within the engine or the clutch assembly.
