Converter Noise

Well on my way to pickup a load of scrap in NYC I noticed a wicked noise and vibration in my truck... Sounded like a knock and had a bit of a grinding sound to it as well. Noise only shows up around idle and slow speeds and isnt always there. Im thinking the converter is starting to go? Looking at options as far as new ones go and wonder what everyones having good luck with. Im running a chip intake and down pipe nothing more and do a bit of towing mostly loads around 6-8k nothing crazy... Any input is appreciated thanks!

This might now be the problem but it's worth checking out. I had a sound similar to that and it turned out to just be a bad U joint. The sound was traveling up the drive shaft to the tranny. Like I said, might not be the problem but worth checking out before you throw a converter on it.

Me an my head mechanic are thinking its actually the flex plate being cracked... he said hes done 3 of them when he worked at his last job.. Going to pull the trans tommorow and hoping its just the flexplate.. The trans feels tight no slipping nothing and the fluids clean. Considering I drove it 100 miles home with that noise im pretty sure it would show some sort of indication through the trans if it was the converter
