My 1000 mile torque converter is taking a **** My videos are gone BTW. even though the links are still up.
Just like I said in the other post, stumped the best transmission guy on here.
Apparently it's very common knowledge and we don't want to throw anyone under the bus.
Again my problem: noise at 0 to 5 mph, loudest in manual second.
Heres the video I posted.
http://www.youtube.com/watch?v=KJDSsve0vOE
You can hear it get louder when you see the car try to move.
I'll try to make a better video tomorrow.
Now look at this video, same thing, way better quality I guess due to a quieter exhaust. Look at the description, exactly what mine is doing: Horrific noise when in gear and brake applied. Noise goes away in park or netural and diminishes when speed increases.

I'm assuming mine will end up that bad if I let it go.
Here is some more info that points to it being common knowledge.
Describes my noise exactly.

Torque converter noises are easy to isolate. Since the entire converter (pump, turbine and stator) turns while the transmission is in park and neutral, a converter noise will go away in those ranges. When the transmission is in gear and the drive wheels are stationary, the turbine in the torque converter doesn't spin, because the turbine shaft is stationary. This is when the bearing between the turbine and main housing of the converter is working. If the noise is there only in gear with the drive wheels stationary and goes away in neutral, suspect the torque converter. There is an exception with the AOD transmission. The direct drum of an AOD is always turning while the engine is running. For this reason, a torque converter noise can be easily confused with the noise made by one of the direct drum bearings.
Tip: A torque converter noise will get quieter as the drive wheels begin rolling slowly from a stop.

What may seem to be a transmission problem sometimes turns out to be a torque converter problem. Worn needle bearings in the torque converter may produce noise when the transmission is in gear, but the noise will go away when the transmission is shifted into neutral. Needle bearings are used inside the torque converter to separate the stator from the impeller, the stator from the turbine, and the turbine from the converter housing.

This is important when diagnosing between a transmission pump and a torque
converter. A transmission pump makes noise in all gears and is directly related to
engine speed. A torque converter will make the most noise when the vehicle is placed
in gear and the wheels held stationary. This is because the turbine is held stationary
while the housing is spinning from engine rotation (working the bearing); while in park
and neutral the noise is gone because the whole unit is spinning. This noise usually
decreases as the vehicle begins rolling forward.

Based on the info you gave in previous post I would have to say its unlikley.
Heres why you said unless I am mistaken that the noise was louder in manual second. Form the converters perspective setting still particularly there is no differential between any gear the selector is in. So if the noise is louder in manual second setting still that it is in any other position then it cannot possibly be the converter.

What else could it be?
You said it could be the increased pressure of having the selector in second, it always starts in second with the selector in 2nd. It makes the noise when the car is not moving and in gear, it quickly goes away with vehicle speed, varies with rpm and is gone by 5-10 mph.

I just connected it to hp tuners and it makes the noise when I use the VCM tools to start off in 3rd. So going off rpm vs gear the noise is there in 1st theres just not much load on anything I guess, so it's not very noticeable, it's louder in manual 2nd, even louder in manual 3rd. Manual 4th I think feels a bit tight and I didn't try it in 4th. I'll go check reverse.

Another video http://www.youtube.com/watch?v=I9k4jAkWTZI
This video you can hear it on acceleration, and it goes away at speed. Sounds like sandpaper rubbing something. I start out once each in 1st, 2nd, 3rd, all set by hp tuners vcm controls, not shifter position so it is starting in 2nd and 3rd.
http://www.youtube.com/watch?v=9PhuruPZ1Ag
This video is useless until the end, the noise can be heard going up the ramps in 1st with the shifter in OD
The rattling I'd assume is the camera mount.
http://www.youtube.com/watch?v=5ShOMVeE86U
The camera was mouted with the microphone near the bottom pass side bellhousing bolt.
Are there any pressure tests I could do to verify what the noise is? Should I put more miles on it and wait for metal to show up in the pan?
I just noticed the noise yesterday and either I got lucky and heard it when it started and it hadn't had a chance to send metal to the filter and pan (because I broke the filter open and there was nothing) or it's not making metal yet?
I don't know what to do. I don't care if it takes out the trans I have another one.

Well not likley related but the max line is a little higher than I like to see. About 210-225 is what I prefer.
I would speak with Chris and see what he thinks but I cant really make any recomendation since though I can hear the video its nothing like actually being there.

Chris will take care of me, but I don't think anyone knows what the noise is (obviously I guess)
He and I both agree it would suck to pull it, cut it open and find nothing.
I have one question for you, I trust your judgement. If it never gets worse, and no metal ever appears in the pan or filter would it be safe to say it's just one of those noises?
I really think I'm going to let it run longer and see what happens. Mainly because I got used to it or something and it seems to drive great, and time to pull it is limited.

I believe I faintly heard the noise you described, but your exhaust is too loud so I really couldn't tell. I would at least check the fluid. If the noise is driving you nuts, put the car on a chassis lift (not a drive on) and try to pinpoint the noise with a mechanics stethoscope. It's probably the most unlikely thing, but check to see if anything is contacting the driveshaft.

My trans made a similar noise several years ago. Drove OK, which is surprising considering what we found:
I put over 100 miles on the car with the noise present, until I lost 3rd and 4th gears and dropped the pan. There was a decent amount of metal in the pan
