do you mean torque converter when you say "tq"?
Is the converter seated completely in the transmission pump? I want to say you should feel 2 distinct clunks when installing it. It helps to turn it as you gently push it on.
You should have about 1/8th inch of clearance between the flexplate and converter, so either you have the wrong or defective bellhousing, or don't have the converter seated fully in the transmission if I am to understand your question..
