TH 350 converter question: noise...

Just installed a remanned TH 350. Filled the torque conveter with 1 qt of fluid before installing it. Then filled tranny. Started car.

There is a noise, coming from the torque converter. It sounds like a noise associated with the converter being unbalanced. It sounds like a light knocking, as if the converter is slightly out of balance. The converter and flywheel is not hitting anything (I have it on a lift, so I can watch and listen) The converter came with the tranny

I let it run only about about 2-3 minutes, while shifting thru the gears. The noise abated somewhat

I havent road tested it yet

Does this sound like the converter is unbalanced?

Has any one had this happen with installing a auto tranny?

A friend of mine used the wrong converter bolts which bottomed out on the flywheel before ever getting tight. It caused a simliar cluncking sound.

I've also seen interference between the converter pan and the flexplate, around the starter provision of the pan. More likely the converter mount bolts though, I agree with MILO.
