Squealing at idle
So I have a squeal at idle that only starts when the truck reaches operating temp. It seems to be coming from the transmission area. It goes away when gas is applied, and starts again at idle. It also goes away when put into gear, but returns in park. I read on a forum someone was saying it was the transmission oil pump. Anyone have anything on this? 2019 lariat 6.7, 1000 miles, it’s done it the whole time.

My transmission has been acting like its slipping as well. Hopefully getting it back in to the dealer soon.

I have a similar issue. 2019 F-450. Idle is the only time it doesn't do it, though. Anything off idle and you can hear it, if I touch the gas at all its there. Almost sounds like a faint brake squeal.

I was having a noticeable squeal/whistle/chirping sound coming from the middle of the truck between 5-10 mph. I narrowed down the location after rolling downhill in neutral with engine off and the sound was not affected by applying the brakes. Had the dealer inspect yesterday and they confirmed it was the Transfer Case Output Shaft Seal as the culprit. They are replacing now. Will report back if that fixes the issue.
