I searched around some and didn't seam to find out if any one else has had this problem, but when I put my car into reverse now, it makes a whining noise similar to water pipes in a house. It's not the typical tranny whine that is common to driving in reverse. Im at 144k and replaced the tranny at 105k covered by the dealership with a three year warranty in march of 2010. Does any one have any idea of what this might be?
