Was the black old fluid an actual oily fluid? Or were there some thick chucks or a thick slime? If it didnt look like reg fluid not counting color, it probly could use a good cleaning on the inside. If you've put some good miles on it since the change open the drain plug and check the color of it. If its black or already darker than the red fluid i'd say you definately need to flush it out. Auto parts stores have that kinda stuff, tho i'm not familiar with it.

When I say lugging I mean driving the truck in a gear thats to high for your vehicle speed forcing your engine rpms down to an idle or lower rpm. For example if your using 2nd gear to take off from a stop or you slow down a bunch like 30 mph and dont downshift at all it'll get a sound like your describing. A real low grrrrrrrrr that seemingly sends vibrations thru the whole truck. You can hear just at well as feel it.

I'd clean it just to feel more comfortable about driving it if it was as bad as its came across to me. A manual wouldnt be as bad as far as sensitivity in the auto since they're actual gears connecting and not a bunch of little clutches inside it.

as far is shifting there's no problem, shifts just fine and easy, no grinding.
What do you guys think about something in the clutch, pressure plate,discs,or a bad throw out bearing, can any of these things be dragging somehow,can it be possible????

I had the truck checked again today by the trany pros, and they couldn't hear it very well, and they said the problem is nothing to worry 4 now, it could be a throwout bearing? They couldn't tell for sure because the sound isn't loud enough to tell what it is?
He also mentioned that the sound is greater when taking off in first gear,
Anyways, they said trany is good and clutch still half life and to drive the truck and don't worry about it.

The throwout can cause that sort of noise when it is going out. No sense in replacing it...you'd end up replacing the whole clutch anyways (if you were smart), so just drive it 'til it goes out or the clutch needs replacement.
Either way, I'd flush the fluid again anyways. After 135K, my fluid was a dark dark maroon color, and it had never been changed by the previous owner. I drained and filled, ran it for three months, drained and filled. It's great now, the intermediate fill and drain came out discolored as well.

I'm getting closer to pinpoint the sound location!
I started the car at night engine cold, and the sound it's almost identical to a "DIESEL" sound, went under the car and touched the catalytic converter with a 2x4, and the sound was still there, but my ear was telling me the sound was getting louder as I was getting closer to the cat?
Got inside the truck, depress the clutch and nothing the diesel sound was still there.
With the parking brake "on" I depress the clutch again and shifted into first gear and released slowly holding it with the parking brake and nothing, no change in the sound, so clutch is not it?
The only thing I can think is a hole in the cat, but I don't see black spots anywhere, and I couldn't see the whole cat very well because of the cat shield.
listened from under the hood and the sound was far away coming from under the truck, anyway the warmer the truck the weaker the sound but not gone.
It's a rattle sound very much like a diesel.

Wasn't there a thread not all that long ago about rattling cats? Seems to me they had it replaced by the dealer under warranty. I wish I had time to search it, but check it out. My weekend starts tonight at 5
, so I'll have time then.

I checked the cats shields and they're Ok, so the sound still a mystery to me!
I know for sure the sound it's coming from under the truck somewhere inside the bellhousing or between motor/bell
?
It's not a detonation pinging, it's a rattle sound like a diesel vehicle?

You had a 2x4...knock the cat with it and see if it makes the noise. Don't be afraid to be pretty rough about it as well. Hopefully it will make a rattling/loose noise.
The cat sheilds have pretty bad welds on them honestly. Two of mine were crap when I got the truck. Rather than re-weld them myself, I just yanked the sheild off. The welds looked solid but the heat sheilds could move slightly, just enough to be annoying.

Done that,
The shields are solid and the sound the shields make are more metallic, mine is a diesel sound, if you had ever listen to the diesel car/truck next to you on the road, that's the sound I hear, not metallic, it can also be a broken cat, but I can't see any black on them? I knocked the cats with a heavy rubber sand filled mallet, and they make no sound just the normal metal sound, but solid,
so I going to concentrate somewhere in the bellhosing, the strange thing is when I clutch down or up no change in the sound?
Next time you hear a diesel vehicle remember the sound, and that's it!

Plenty of diesels around here, and I cannot think of anything in the bellhousing area that makes any sound like that, and definetly not that loud. Is it loud enough to hear when the truck is sitting there and you're in the seat?
