Hello everyone, I'm new here. I have a really puzzling intermittent sound coming from the flywheel/torque converter area of my 07 5.9. It almost sounds like the starter trying to engage for a bit, them it goes away if I back off the acceleration. I ruled out the starter (started truck and removed the starter and drove, still had the sound).
My mechanic just replaced the torque converter under warranty, trying to get rid of the sound. Tranny fluid is clean, it was just rebuilt last fall, not sure what else to look for.
I'll try to attach a video, when the sound first started it would happen at idle, but now only occasionally driving at acceleration.
Any thoughts?

 

Well it won't upload my video format. I'll try another in the morning

 

Well I got a video converted. Anyone recognize that clatter sound?
Thanks for any suggestions,
Anthony
