Angry what is that noise?

I've got a 2003 f350 powerstroke. It's got 27k on it and is in beautiful shape. Until today...driving home from work started when I hearing a noise that I thought was a rock in my tire. When I started slowing down I could hear what sounded like metal tossing around that slowed when I did. Couldn't hear it at high speeds just when slowing down. Then the truck started shifting with a clunk from 2nd to 3rd. Getting frustrated just got the truck a week ago and already problems...anybody have any idea what is going on?

when I buy a new vehicle, I like to do my own fluid changes to manufacturers spec. Several reasons for this, 1..I know I'm good for XXXX miles depending on the fluid changed and 2...I can see if there is debris, shavings, coolant, water..whatever in the fluid I changed out so I know what to look for..and change or send back to a dealer (if I bought it from there) for repairs. I'd recommend doing the same, its real inexpensive compared to replacing an automatic transmission, transfer case, or rear axle. That should pinpoint your problem though.

While reading this, before I got to the part that you said it was shifting funny, I would have bet my last dollar on front wheel bearing. But the shifting part threw me off. Might be 2 separate problems, that just happened at the same time.

I would at least, Jack up the front end and see if there is any slop or movement in your hubs. Then also drain trans fluid, change filters, and see if there any material in your trans pan magnet...

The metal noise is coming from under the cab, it is definetly shifting hard from 2nd to 3rd. When it shifts its got a little hesitation then a clunk, sounds like if you had something in the bed and it slammed against the tail gate.

Got the truck back from Ford today they said it has a bad icp sensor. They seem to think this is what's causing the shifting problem. Why would I hear a clunk in the rear end if its the icp sensor? They also said that its normal to have a little bit of a hard shift from 2nd to 3rd. This doesn't seem normal to me, this is the first powerstroke that I've owned, but my boss of 15 years has always owned them and I don't ever remember any of them shifting hard like this. Getting the sensor on Wednesday, hope it fixes this mess
