Whining or moan noise, 2003 S-10 pickup

New truck, 4.3 v6, auto tranny, when it is cold it has a whine, that I don't know what it is. It doesn't seem like the tranny. The dealer sez a lot of them do it ,but he doesnt know what it is. Any ideas?

It does not seem to effect the truck in any way, and it gos away after warmup. thanks, Andy

Hi!

It's the diff making noise in the cold. Scared the hell out of me one day when it started moaning while I was going down the road at about 25MPH. Mine sounded like a faint police siren whaling at just the right RPM and speed.

It is nothing to worry about. Mine did it all of the first winter I owned it. A year later it has not done it once, even in bitterly cold weather.

I have an '03 Silverado, and the tranny whines in it, too.
