Default Idler noise?

I am getting a noise that sounds like a bad idler pully... It sounds like it is directly under the drivers seat but outside of the truck... It doesn't do it at idle or at any certain rpm at a stop... It does it going down the road when you let off and coast. It don't do it under say 5mph... It's not the idler pully or a bad belt I'm stumped on this one!? I checked the u joints and they are good and it doesn't sound like its coming from the wheel bearing... And it's not something rubbing I checked and nothing loose under there... It almost sounds like something in the tranny? Which has me worried bc of the minor slip I had the other day...

Has anyone had this same issue before? I'm trying to get a friend to check under there will I'm driving but it's pretty dangerous

Like a tea kettle whistle when you let off the throttle?

Not a tea kettle it sounds just like a squeaky idler pully kind of like a belt slipping? I have been doind some research and the best I can come up with is the torque converter?

I'm going to take the front drive shaft off to see if that changes and recheck the rear u joints... But I've never heard a ujoint make this noise

They can certainly make those noises. I highly doubt you can hear the torque converter...

Tough to say without the truck in front of us... this is odd. Definitely let us know what you find.

Took it out on the high way and ran her for awhile and only got my lie-0-meter to go to 9.0mpg . The noise went away after the drive... So I'll let it cool back down and check it again

And I also just noticed that the factory oil pressure gauge does not move for atleadt 10 seconds when I start it...? It seemed like it had a miss to it while I was cruising on the highway too?
