4l80E Lock Up Question Help?

I swapped an 80 into my 2000 camaro just got it out, a couple of issues im wondering on, when the converter locks up it makes a bad clunking noise, when im driving at cruise speed it seems like the converter is locking and unlocking? Any sugestions.

Thanks!

Are you throwing an codes at all? I have read that if you are throwing codes it can force the converter to lock and unlock like you are describing. Not sure about the clunking sound.
