Very noisy tourque converter

I have a 97 F350 Powerstroke. Two days ago the converter started making a chattering sound just like the one in the following video.Well I don't seem to be able to upload the link but it can be found on Youtube at:


In the comments with the video many said to check flex plate for cracks and/or lose bolts which I have done. With trans still in truck I can see no cracks and no lose nuts. Noise appeared very suddenly (day before fine, started next day to noise).

OK it did upload. This was posted by someone else. This is not my truck but the sound is exactly the same.

How many miles? Tc / flex seems to be making the noise. The stock tc isn’t known to be very “tough”. Drop the transmission is best I can tell ya. You’ll see exactly what’s wrong once she’s apart.

Re: Very noisy tourque converter

@Cummins Junkie your signature statement couldn't be more correct. I do miss my ol' 94 Dodge Ram 2500 12V Cummins. I owned that truck for 9 years (sold it last year) before the frame finally gave out, drivetrain still running strong. Now i know you folks are all about Ford here so I may be shooting myself in the foot but I spent less on major repairs on that truck in almost 10 years as I have on this beast in 1 and it worked a hell of a lot harder. Every week it's something else. OK, OK guys ranting over, sorry. Wasn't going to say anything but with that signature statement I couldn't resist.:-) Down to business.

Hi DieselDC, trying not to drop trans YET, mileage around 225K. I have checked the flex plate carefully w/ mirror and flashlight and see no cracks (can't see where it bolts to crank). I have put a wrench on all flex to torque nuts to check for looseness, all tight (again can't see bolts for flex to crank). SO I am leaning towards bad tc. Now that being said can anyone give me an idea of what is happening inside the converter and can I drive for a couple more days without completely blowing it up? I have a line on a cheap rig but this is the only wheels I have. Don't know if this helps but when moving at road speed noise is diminished considerably.

Re: Very noisy tourque converter

As far as how the tc tears up, clutches wears out, impellers breaks (attaches to the input of transmission), lock up clutch wearing (causes shudder 30-45mph) etc.

SO I guess what you're saying is, at best, not good.

Drop that nonsense. Do you want to fix it? Or damage more?

Keep it up while it’s still together... once it takes a chit, metal parts will spread all over and you’re gonna need new everything.
