01 aurora transmission whine.
 

Hello everyone. I have a 2001 aurora 3.5L with 104,000 miles. 85% of the time I drive the car it drives perfectly,shifting as usual. From time to time I'll start it up and it shifts hard, and has a high pitched whine that sounds as if it is coming from the Transmission. If I turn the car off and then back on it is usually gone immediately. Please help me out.
