Are you sure your torque converter isn't massively out of balance or something? Again....010" isn't going to mean anything on the oil pan.
I suspect that the converter could be a source of the problem. It was new when I installed the trans and my transmission builder was able to clean up the snout and we reused it this second time. I've never heard of a converter with bad runout or balance problems, but I don't have access to a lathe to check it.

I've thought of just bolting it to the flexplate without the trans, but I suspect it will just distort the flexplate due to the weight and make it difficult to get a runout measurement. I should mount it just to see how the crank fits.
