I have a 2000 f-150 w/ a 4.6 eng. I was pulling my camper ,which is 2000 lb we were on US 70 going across the Rockies when going up to Loveland Pass and when it kick into the passing gear and got up to speed right before shifting back there is a winding noise for about 3-5 seconds, then it goes away after it shifts. thanks, I hope this makes sence
