Re: Weird sound please help
I posted something similar.
I was thinking about it, and I've noticed that the problem goes away with the clutch disengaged. Only thing I can think of is that a belt might be the cause, as it sounds like it's coming from underhood, instead of underneath. I'm thinking that since it varies with engine noise, it might be a drivebelt or a timing belt. When I last changed my engine oil, I noticed my drive belt was really worn, so I'm going to see if that solves the problem...if not, I'm probably going to have to change the timing belt. As for it being the transmission, I'm going to say no, only because I usually keep my hand on the shifter after shifting, and I've never noticed any kind of vibration or clunking when it's in gear. Usually, the whine only comes when the gas is pressed.
Just my thoughts.

As a thought, I would do the following to see where it's coming from:
Put the rear of the truck on jackstands, making sure to block both of the front wheels so it doesn't roll. Start it, and then act like you're going to accelerate with it in gear. Now, if the whine goes away, it's in the driveline somewhere, because of the fact that while in the air, there's no load on the tires, axles, bearings, etc. If it's still there, then it is either in the transmission (hope not) or in the engine. Could also be the clutch is also worn out, which would taking it apart and looking at everything to determine the cause.
