Transmission problem
2005 Ford Explorer 6 cyl Four Wheel Drive Automatic 60,000 miles
----------------------------------------------------------------
at approx. 57-62 mph, my SUV makes a whining noise. I brougt to dealership, it's under warranty, and they said they heard the noise, fixed the bearings and according to them the noise is gone. After two days the noise is back. Can you give me an indication what it might be so I may ask them to look at it?
