hey guys,
I have a 4l46e that is consistently leaking. I replaced the pump and input seal and it slowed to next to nothing for a little while, but today it started leaking bad again. Starting to think it is the converter? is this possible? could it be defective and destroying the seal or have a crack? it is a billet aftermarket unit.

also how does one go about testing a converter for leaks or defects?
