Automatic Tranny noise on start
This is going to be one of those highly subjective posts, but I'll give it a go. My 2000 Ranger, 3 liter automatic has begun making this high pitched whirring noise when starting out from a stop. I liken the noise to a police siren, not that loud of course, but its getting louder and louder as time goes by. I think I started noticing it at 60K, now that my truck passed the 80K miles mark its making me wonder.
So here are the basics, a high pitched whirring noise when I come off the line from a full stop. It is very noticable when I stomp on the gas (as I typically do), and the whirring noise goes away almost immediately. Other than that no other noises or issues with the truck.

Gas in neutral
I hadn't actually thought of that.
The noise sounds like its coming from the back of the truck or right under me, rather than from the front. But, you do have a good point, I'll give it a go tomorrow and see what happens. I'm pretty sure the answer will be "No, it doesn't make that sound when in neutral", but I guess I won't know until I try.
Personally I was wondering if maybe my torque converter might be going out.

Tranny noise
Well it isn't the belt. No strange noises when the truck is in neutral.
Are there tests that can be done on an automatic tranny to see how its doing and to help pinpoint issues before they become catastrophic?

Riding in the bed
I don't think that is going to happen. I certainly wouldn't condem someone to that kind of punishment. I appreciate you willingness to help here, and I do understand that diagnosing a transmission problem by sound is pretty far out there.
I wish there was some kind of road test I could give my truck to single out any problems. I heard on the net somewhere that you can put your truck in 1st gear, put on the parking brake, push in the brakes, then push the accelerator. The test should show how many RPM's you can get and also tell you how well your Torque converter is doing. However it stated that this test isn't always recommended by the manufacturers for the stress that it puts on the drivetrain. Would you all know if Ford definitely wouldn't recommend this test?
