Ford F250 Superduty auto transmission whines
I have a 2000 Ford F250 Superduty with a 6.8L V10 and auto transmission. Last night I was hauling a 600# ATV, and the transmission started whining between 45 and 60 MPH, but only under load. It quits if you let off the gas. Shifted into neutral while rolling, and the noise stopped. Does anyone have any ideas what to look at?
